1 00:00:03,040 --> 00:00:05,840 Speaker 1: Welcome to stuff to blow your mind from house up 2 00:00:05,920 --> 00:00:30,240 Speaker 1: works dot com. The allosaurus attacks, his teeth plunge like knives. 3 00:00:30,960 --> 00:00:36,519 Speaker 1: The Diplodocus's skin turns ragged and red. The allosaurus bites deeper, 4 00:00:37,360 --> 00:00:41,519 Speaker 1: his claws gripped her belly. A frightened diplodocus roars to 5 00:00:41,600 --> 00:00:46,720 Speaker 1: the herd. Another diplodocus swings his rump sideways. His bony 6 00:00:46,760 --> 00:00:50,479 Speaker 1: tail snaps like a whip through the air. The allosaurus 7 00:00:50,560 --> 00:00:55,400 Speaker 1: falls back, his eyes sting like fire. The mother quetsoco 8 00:00:55,480 --> 00:00:59,640 Speaker 1: Atlas jerks backwards in fear. She hears her maid calling 9 00:00:59,720 --> 00:01:04,560 Speaker 1: as he flies overhead. Too late. The dromeo Saurus attack. 10 00:01:05,080 --> 00:01:10,120 Speaker 1: They swallow eggs hole, they rip leathery wings. The quetso 11 00:01:10,200 --> 00:01:13,800 Speaker 1: co Atlas swoops down as near he dares he sees 12 00:01:13,880 --> 00:01:20,080 Speaker 1: and understands. He turned sharply away. I am quetzo co Atlas. 13 00:01:20,120 --> 00:01:23,680 Speaker 1: The ground trembles below me. I glide over the rock 14 00:01:23,800 --> 00:01:28,880 Speaker 1: ledge and soar into the sky. Hey, you welcome to 15 00:01:28,880 --> 00:01:30,960 Speaker 1: stuff to blow your mind. My name is Robert Lamb, 16 00:01:31,000 --> 00:01:33,759 Speaker 1: and I'm Joe McCormick. And Robert I gotta ask, when 17 00:01:33,880 --> 00:01:36,880 Speaker 1: you are at home reading dinosaur books with your son, 18 00:01:37,120 --> 00:01:39,720 Speaker 1: do you read them out loud in that Tulsa Doom 19 00:01:39,800 --> 00:01:41,759 Speaker 1: voice you just did. Yes, if I can get away 20 00:01:41,800 --> 00:01:45,520 Speaker 1: with it, I use voices, but sometimes he just says, 21 00:01:45,640 --> 00:01:48,680 Speaker 1: use your regular voice, dad, and I I have to 22 00:01:48,720 --> 00:01:52,920 Speaker 1: oblige or he could just grow up thinking that Fulsa 23 00:01:52,920 --> 00:01:58,160 Speaker 1: Doom is his dad. Well, these books in particular really 24 00:01:58,200 --> 00:02:02,080 Speaker 1: really encourage a very dramatic reading. Now who wrote these 25 00:02:02,080 --> 00:02:04,680 Speaker 1: two we were looking at it was two different books. Yes, 26 00:02:04,720 --> 00:02:08,320 Speaker 1: now these are. One book is called I Am Quetzalcoatlas 27 00:02:08,480 --> 00:02:11,240 Speaker 1: and the other one is I Am Diplodocus. These were 28 00:02:11,240 --> 00:02:15,399 Speaker 1: written by Karen Wallace and illustrated by Mike Bostock. Now, 29 00:02:15,560 --> 00:02:17,919 Speaker 1: you sent me a link to these on Amazon, and 30 00:02:17,960 --> 00:02:19,880 Speaker 1: I went and looked it up, and it is so 31 00:02:19,960 --> 00:02:23,480 Speaker 1: funny because there is just one star review is coming 32 00:02:23,520 --> 00:02:28,040 Speaker 1: out the eye sockets. People are mad about these books. Yeah, 33 00:02:28,120 --> 00:02:29,920 Speaker 1: the first of all, I want to get out there. 34 00:02:29,919 --> 00:02:32,320 Speaker 1: These are great books. I highly recommend. These are five 35 00:02:32,320 --> 00:02:34,600 Speaker 1: star books in my opinions. These are these are dinosaur 36 00:02:34,680 --> 00:02:37,680 Speaker 1: children's but dinosaur children's books. And uh. And when I 37 00:02:37,720 --> 00:02:39,840 Speaker 1: say I love them, I'm not being like ironic, like, 38 00:02:39,880 --> 00:02:41,919 Speaker 1: oh it's a horrible book, and you know it's but 39 00:02:42,280 --> 00:02:44,320 Speaker 1: I but I find something weird about them. Now, these 40 00:02:44,360 --> 00:02:47,840 Speaker 1: are these are great dinosaur books, but they are a 41 00:02:47,880 --> 00:02:51,120 Speaker 1: bit dark, or at least they're a bit realistic. You know, 42 00:02:51,440 --> 00:02:54,000 Speaker 1: so many dinosaur books are like kids having adventures with 43 00:02:54,040 --> 00:02:58,240 Speaker 1: dinosaurs or things are kind of whitewashed. No, these these 44 00:02:58,240 --> 00:03:01,959 Speaker 1: books encourage the child to look through the eyes of 45 00:03:01,960 --> 00:03:06,920 Speaker 1: of of an animal living in an in an ancient time, uh, 46 00:03:07,160 --> 00:03:11,560 Speaker 1: competing for resources, having to deal with the relentless predators, 47 00:03:12,160 --> 00:03:15,800 Speaker 1: encountering death and injury, and and I think all the 48 00:03:15,800 --> 00:03:19,919 Speaker 1: ones I've read end in death. Uh. But and it's 49 00:03:19,960 --> 00:03:22,760 Speaker 1: weird because when I read the first one to my son, 50 00:03:22,840 --> 00:03:26,040 Speaker 1: which I think was the quets solco Atlas one, I 51 00:03:26,080 --> 00:03:28,639 Speaker 1: was reading it for the first time allowed to him, 52 00:03:28,680 --> 00:03:31,840 Speaker 1: and we were getting to the violence, and then we 53 00:03:31,840 --> 00:03:36,200 Speaker 1: were getting to the part where the male Quetsoco Atlas 54 00:03:36,200 --> 00:03:39,120 Speaker 1: flies over and sees his family consumed by predators, and 55 00:03:39,120 --> 00:03:41,560 Speaker 1: I was like, oh my god, my kid's gonna lose it. 56 00:03:41,600 --> 00:03:44,520 Speaker 1: This is too dark, this is too violent. He doesn't 57 00:03:44,760 --> 00:03:48,200 Speaker 1: he makes a skip over predation and documentaries. He's not 58 00:03:48,240 --> 00:03:52,960 Speaker 1: crazy about super dramatic scenes in children's movies, so I 59 00:03:53,000 --> 00:03:54,760 Speaker 1: didn't think he'd be able to handle this, but he did. 60 00:03:54,800 --> 00:03:57,720 Speaker 1: He loved it, and and he has this, I don't know, 61 00:03:57,720 --> 00:04:00,880 Speaker 1: an interesting disconnect where if it's dying a saur violence, 62 00:04:01,240 --> 00:04:03,600 Speaker 1: it's okay. If he has a whole book about like 63 00:04:03,640 --> 00:04:06,200 Speaker 1: it's called The Death of the Dinosaurs, it's a kid's 64 00:04:06,240 --> 00:04:09,520 Speaker 1: book in which it's just it's basically Corman McCarthy's The 65 00:04:09,600 --> 00:04:13,600 Speaker 1: Road with Dinosaurs, Death after Death after Death. And he 66 00:04:13,800 --> 00:04:15,200 Speaker 1: and after we read it, he was like, oh, that's 67 00:04:15,200 --> 00:04:16,960 Speaker 1: a great book. I love that. Yeah, there is no 68 00:04:17,080 --> 00:04:21,240 Speaker 1: God and we are his dinosaur prophets. Uh. And indeed, 69 00:04:21,279 --> 00:04:24,320 Speaker 1: one of the reviews for the uh for the book 70 00:04:24,480 --> 00:04:27,200 Speaker 1: by Karen Wallace, I am a t rex Ryan Toronto 71 00:04:27,279 --> 00:04:30,800 Speaker 1: Tyronosaurs Rex. Uh. One of the one star reviews, someone said, 72 00:04:30,839 --> 00:04:33,240 Speaker 1: this reads like a Cormy McCarthy novel. They did, and 73 00:04:33,279 --> 00:04:35,040 Speaker 1: I agree with them, but in a good way, in 74 00:04:35,080 --> 00:04:37,320 Speaker 1: a five star way. A lot of these one star 75 00:04:37,360 --> 00:04:40,440 Speaker 1: reviews featured lots of direct quotes from the books, like 76 00:04:40,600 --> 00:04:47,880 Speaker 1: lists of words ripping, slicing, slashing, tearing, and thieving. I'm sorry, whoever, 77 00:04:47,920 --> 00:04:51,800 Speaker 1: I just quoted from the internet, but uh, yeah, yeah, yeah, 78 00:04:51,839 --> 00:04:54,000 Speaker 1: I mean there there is a certain way in which 79 00:04:54,040 --> 00:04:59,839 Speaker 1: I understand how dinosaur violence can seem different than violence 80 00:04:59,880 --> 00:05:02,279 Speaker 1: the it's taking place in the present. I mean, for 81 00:05:02,400 --> 00:05:08,840 Speaker 1: one thing, we definitely do have a time desensitization mechanism 82 00:05:08,960 --> 00:05:11,680 Speaker 1: in our brains. And in the same way that if 83 00:05:11,720 --> 00:05:16,240 Speaker 1: you hear about how yesterday a thousand people were massacred, 84 00:05:16,279 --> 00:05:20,120 Speaker 1: that is a heartbreaking tragedy. But if you hear about 85 00:05:20,520 --> 00:05:23,560 Speaker 1: how a thousand years ago a thousand people were massacred, 86 00:05:23,600 --> 00:05:27,680 Speaker 1: it's fodder for jokes. It just doesn't it just doesn't 87 00:05:27,720 --> 00:05:29,719 Speaker 1: resonate in the same way. I guess it was no 88 00:05:29,839 --> 00:05:32,440 Speaker 1: less tragic then, but it just really doesn't hit you. 89 00:05:33,560 --> 00:05:36,360 Speaker 1: And dinosaurs may suffer from that, but I think they 90 00:05:36,480 --> 00:05:40,800 Speaker 1: also are subject to a kind of conditioning in the 91 00:05:40,880 --> 00:05:44,359 Speaker 1: brain that comes from dinosaur illustrations, which is that, at 92 00:05:44,440 --> 00:05:46,600 Speaker 1: least in my mind. Maybe maybe this is not true 93 00:05:46,640 --> 00:05:49,400 Speaker 1: across the board, but when I scan my memory of 94 00:05:49,480 --> 00:05:54,599 Speaker 1: dinosaur illustrations from my childhood, they're always action scenes. Something 95 00:05:54,680 --> 00:05:57,680 Speaker 1: violent is happening or is about to happen. It's not 96 00:05:57,720 --> 00:06:01,120 Speaker 1: just lots of pictures of you know, some herbivore standing 97 00:06:01,160 --> 00:06:05,240 Speaker 1: around in the water, drinking water, eating leaves, maybe a 98 00:06:05,320 --> 00:06:10,000 Speaker 1: carnivore just basking in the sun. There's always feeding imminent 99 00:06:10,320 --> 00:06:14,120 Speaker 1: or or fighting taking place. Something's leaping at something else, 100 00:06:14,279 --> 00:06:19,280 Speaker 1: mouth open, claws extended, they're wrestling. I think of that, Uh, well, 101 00:06:19,320 --> 00:06:22,000 Speaker 1: this wouldn't be dinosaurs, but it would be prehistoric animals. 102 00:06:22,040 --> 00:06:25,680 Speaker 1: I think of that iconic image of the saber tooth cat, 103 00:06:25,800 --> 00:06:28,120 Speaker 1: and it's some other scavenger I don't remember what, maybe 104 00:06:28,160 --> 00:06:31,919 Speaker 1: a dire wolf fighting over a mammoth carcass. Yeah, I 105 00:06:31,920 --> 00:06:35,640 Speaker 1: mean paleo art is rich. There's there are a lot 106 00:06:35,680 --> 00:06:37,800 Speaker 1: of just wonderful works there. I mean, especially when you're 107 00:06:37,839 --> 00:06:40,919 Speaker 1: dealing with with actual painted paleo art and and not 108 00:06:41,120 --> 00:06:43,720 Speaker 1: some of the c g I stuff. You find a 109 00:06:43,720 --> 00:06:46,840 Speaker 1: lot of the times now and you do have scenes 110 00:06:46,880 --> 00:06:49,839 Speaker 1: of like peaceful duck built dinosaurs out in the water. 111 00:06:49,960 --> 00:06:51,719 Speaker 1: But the ones that stick with us, and the certainly 112 00:06:51,760 --> 00:06:53,880 Speaker 1: the ones that I remember from dinosaur books to chin 113 00:06:54,200 --> 00:06:57,360 Speaker 1: and then I'm rediscovering now with my almost five year old, 114 00:06:58,200 --> 00:07:01,880 Speaker 1: are these scenes, like you say, I'm drum attic encounters 115 00:07:01,920 --> 00:07:06,800 Speaker 1: of a one dinosaur battling another herbivore versus predator duking 116 00:07:06,880 --> 00:07:10,320 Speaker 1: it out in a prehistoric landscape. I mean, that's the 117 00:07:10,320 --> 00:07:12,440 Speaker 1: stuff that draws us in usually also there's like a 118 00:07:12,520 --> 00:07:16,200 Speaker 1: volcano or roughing in the background. Why is that, Well, 119 00:07:17,080 --> 00:07:19,600 Speaker 1: you know, I guess tying in like the whole extinct, 120 00:07:19,720 --> 00:07:21,800 Speaker 1: like the the extinction of the dinosaurs is wrapped up 121 00:07:21,800 --> 00:07:25,000 Speaker 1: in them. They're like the Norse gods, of of of 122 00:07:25,080 --> 00:07:28,680 Speaker 1: prehistoric creatures. True, yeah, they existed for like tens of 123 00:07:28,760 --> 00:07:31,480 Speaker 1: millions of years, and yet in our minds they're constantly 124 00:07:31,520 --> 00:07:35,560 Speaker 1: going extinct. But but you're right, there's almost always a volcano. 125 00:07:35,640 --> 00:07:39,960 Speaker 1: It's like two animals fighting volcano in the background. Crazy 126 00:07:40,040 --> 00:07:43,280 Speaker 1: like the fight scenes you see for dinosaurs, Like how 127 00:07:43,320 --> 00:07:46,440 Speaker 1: often do you encounter something that climactic even in our 128 00:07:46,480 --> 00:07:51,760 Speaker 1: biggest blockbusters, like two to combatants battling killing each other 129 00:07:51,760 --> 00:07:55,720 Speaker 1: as a volcano erupts in the background. Um, it's crazy stuff. 130 00:07:55,960 --> 00:07:57,720 Speaker 1: I guess that's how it's got to be. And you 131 00:07:57,720 --> 00:08:00,760 Speaker 1: know what, it's probably not the fact or not the 132 00:08:00,800 --> 00:08:03,320 Speaker 1: case that that's really what the dominant art is is. 133 00:08:03,360 --> 00:08:05,680 Speaker 1: Just that's what I remember. I think you it makes 134 00:08:05,680 --> 00:08:07,960 Speaker 1: an impact. You know, you've probably called that out right. 135 00:08:08,600 --> 00:08:12,280 Speaker 1: But one thing that's kind of cool is that you 136 00:08:12,400 --> 00:08:15,520 Speaker 1: don't have to go to fiction to find a few 137 00:08:15,560 --> 00:08:18,920 Speaker 1: of these crazy action scenes from the prehistoric world, and 138 00:08:18,960 --> 00:08:22,400 Speaker 1: this brings us to our topic today. Robert, you suggested 139 00:08:22,440 --> 00:08:27,160 Speaker 1: this episode and the idea is fossil action scenes. Now, 140 00:08:27,200 --> 00:08:28,840 Speaker 1: what made you want to do this? Was it just 141 00:08:28,880 --> 00:08:32,200 Speaker 1: reading these books? Yeah? It was really um. I mean 142 00:08:32,240 --> 00:08:34,600 Speaker 1: I encountered stories about some of the some of these 143 00:08:34,640 --> 00:08:37,079 Speaker 1: major finds before. But when I read to my son 144 00:08:37,080 --> 00:08:39,800 Speaker 1: about dinosaurs, I I read some of these kids books. 145 00:08:39,840 --> 00:08:43,439 Speaker 1: But we also go through the Macmillian Illustrated Encyclopedia of 146 00:08:43,480 --> 00:08:46,640 Speaker 1: Dinosaurs and Prehistoric Animals, which is an older book, and 147 00:08:46,720 --> 00:08:48,720 Speaker 1: certainly as we read through it, we have I have 148 00:08:48,800 --> 00:08:51,760 Speaker 1: to remind myself that I'm not dealing with a recent text. 149 00:08:51,800 --> 00:08:55,040 Speaker 1: It's like twenty or maybe thirty years old at this point, 150 00:08:55,240 --> 00:08:57,800 Speaker 1: so it's probably got some outdated info. But man, those 151 00:08:57,840 --> 00:09:00,520 Speaker 1: illustrations make up for that is gorgeous. Us. I'm looking 152 00:09:00,520 --> 00:09:02,880 Speaker 1: at it right now. It's a gorgeous, gorgeous book. Imagine 153 00:09:02,880 --> 00:09:04,520 Speaker 1: some of you listening and grew up with it as well. 154 00:09:04,679 --> 00:09:06,600 Speaker 1: But it makes mention of some of these As we 155 00:09:06,600 --> 00:09:10,960 Speaker 1: read the more in depth discussions on these these different 156 00:09:11,000 --> 00:09:14,160 Speaker 1: fossil finds, it'll mention. Oh yeah, there is an encounter 157 00:09:14,280 --> 00:09:19,200 Speaker 1: between protoceratops and this particular predator. Uh and and and 158 00:09:19,400 --> 00:09:22,920 Speaker 1: we've learned a lot from what this creature consisted of 159 00:09:22,960 --> 00:09:26,440 Speaker 1: based on this fossil find. Now you might be wondering, well, 160 00:09:26,480 --> 00:09:28,760 Speaker 1: why why would that be such a special thing. I mean, 161 00:09:28,840 --> 00:09:32,600 Speaker 1: these animals live for millions of years and they get fossilized. 162 00:09:32,640 --> 00:09:34,800 Speaker 1: So why wouldn't we see all kinds of action scenes 163 00:09:34,800 --> 00:09:37,000 Speaker 1: in the fossil record? Why is that a rare and 164 00:09:37,080 --> 00:09:40,160 Speaker 1: wonderful thing to come across? Well, you have to think 165 00:09:40,200 --> 00:09:43,280 Speaker 1: a little bit about the conditions under which fossils arise 166 00:09:43,360 --> 00:09:46,720 Speaker 1: to understand why this really shouldn't happen all that often. Yeah, 167 00:09:46,800 --> 00:09:49,120 Speaker 1: and really it makes it makes these encounters all the 168 00:09:49,160 --> 00:09:52,719 Speaker 1: more amazing. So so yeah, stick stick with us here 169 00:09:52,720 --> 00:09:56,720 Speaker 1: as we dive into just how fossilization occurs. Right, Okay, 170 00:09:57,400 --> 00:10:01,160 Speaker 1: So when we think of fossils, were usually thinking of bones, 171 00:10:01,400 --> 00:10:04,240 Speaker 1: But that's actually a little bit narrow because a fossil, 172 00:10:04,320 --> 00:10:06,959 Speaker 1: in reality, as the term would be used by somebody 173 00:10:06,960 --> 00:10:11,400 Speaker 1: who works in paleontology or biology, is a physical remnant 174 00:10:11,720 --> 00:10:15,120 Speaker 1: of any kind left behind by an organism that lived 175 00:10:15,160 --> 00:10:18,800 Speaker 1: in a previous geological age. So these could be things 176 00:10:18,840 --> 00:10:24,040 Speaker 1: like preserved footprints or eggs or nest sites, burrows, things 177 00:10:24,040 --> 00:10:27,120 Speaker 1: like that are sometimes fossilized. Or of course it could 178 00:10:27,120 --> 00:10:29,920 Speaker 1: be the things were more familiar with body parts themselves. 179 00:10:29,960 --> 00:10:32,760 Speaker 1: If it's more recent, it might even include maybe uh, 180 00:10:32,840 --> 00:10:36,559 Speaker 1: soft tissue encased in ice or resin and stuff like that. 181 00:10:36,600 --> 00:10:40,199 Speaker 1: But more often with the much longer extinct animals we're 182 00:10:40,240 --> 00:10:45,199 Speaker 1: talking about, uh, fossilized bones, these geological entities that come 183 00:10:45,240 --> 00:10:49,560 Speaker 1: up from the bedrock. Now, the vast majority of animals 184 00:10:49,600 --> 00:10:53,760 Speaker 1: that die don't get fossilized. And you can probably figure 185 00:10:53,800 --> 00:10:55,760 Speaker 1: this out if you just do a little mental math 186 00:10:55,800 --> 00:10:59,760 Speaker 1: about how many organisms have ever existed and how you're 187 00:10:59,800 --> 00:11:04,440 Speaker 1: not constantly wading through fossils on planet Earth. Um, there 188 00:11:04,440 --> 00:11:06,440 Speaker 1: are a bunch of hurdles you have to pass through 189 00:11:06,679 --> 00:11:10,000 Speaker 1: to turn from a regular dead animal into a fossil. 190 00:11:10,600 --> 00:11:13,360 Speaker 1: First of all, fossilization is going to strongly prefer animals 191 00:11:13,360 --> 00:11:18,040 Speaker 1: with hard body parts, right, you want to have bones, teeth, shells, 192 00:11:18,360 --> 00:11:21,520 Speaker 1: animals that don't have hard body parts. If you're a 193 00:11:21,640 --> 00:11:25,440 Speaker 1: jelly fish or a slug or something like that, you're 194 00:11:25,520 --> 00:11:30,959 Speaker 1: almost always going to decompose entirely and just disappear into history. Also, 195 00:11:31,040 --> 00:11:35,120 Speaker 1: fossilization depends very much on the environment. It's much more 196 00:11:35,160 --> 00:11:39,200 Speaker 1: likely to happen in an environment that promotes rapid burial, 197 00:11:39,400 --> 00:11:41,880 Speaker 1: because you can think about it, it's pretty intuitive. Actually, 198 00:11:41,920 --> 00:11:46,640 Speaker 1: the longer a dead organism lies exposed to the open environment, 199 00:11:46,760 --> 00:11:48,880 Speaker 1: the you know, the seafloor or the air or whatever 200 00:11:48,920 --> 00:11:51,520 Speaker 1: it might be, the more vulnerable it is to all 201 00:11:51,600 --> 00:11:54,080 Speaker 1: kinds of pressures that would destroy it. So this could 202 00:11:54,120 --> 00:12:01,040 Speaker 1: be scavenging, scavenging by animals, decomposition by microbial life, erosion 203 00:12:01,280 --> 00:12:04,720 Speaker 1: by forces like wind and tidal action and stuff like that, 204 00:12:04,800 --> 00:12:08,000 Speaker 1: and just general destruction. If you're sitting out in the open, 205 00:12:08,679 --> 00:12:10,680 Speaker 1: the parts of your body, even the hard parts of 206 00:12:10,679 --> 00:12:14,280 Speaker 1: your body, you're gonna get worn down and destroyed over time. Yeah, 207 00:12:14,320 --> 00:12:16,440 Speaker 1: I mean I always think that too. When I when 208 00:12:16,440 --> 00:12:18,640 Speaker 1: I was a kid and I lived in a rural area, 209 00:12:19,080 --> 00:12:21,400 Speaker 1: we'd go the same way to school every day or 210 00:12:21,440 --> 00:12:24,480 Speaker 1: into town every day, and there was a dead fox 211 00:12:24,520 --> 00:12:26,679 Speaker 1: at one point, and every maybe it was a coyote, 212 00:12:26,720 --> 00:12:29,040 Speaker 1: I can't remember, but every time you pass, there'd be 213 00:12:29,080 --> 00:12:32,640 Speaker 1: a little less of it, would be a little more scattered, because, yeah, 214 00:12:32,640 --> 00:12:35,280 Speaker 1: a body is going in a natural environment, it's just 215 00:12:35,280 --> 00:12:38,240 Speaker 1: gonna be scavenged and torn apart, and then it's going 216 00:12:38,280 --> 00:12:41,679 Speaker 1: to break down like that. That coyote is never going 217 00:12:41,720 --> 00:12:44,000 Speaker 1: to be a fossil. Uh. The route where I walk 218 00:12:44,120 --> 00:12:50,040 Speaker 1: my dog Charlie has of late had a slowly settling 219 00:12:50,240 --> 00:12:53,720 Speaker 1: pile of fur with a couple of visible jawbones and 220 00:12:53,800 --> 00:12:56,280 Speaker 1: teeth and stuff. Not sure what that was. At some 221 00:12:56,360 --> 00:13:00,080 Speaker 1: point it was something mammalian. Uh. And yeah, you you 222 00:13:00,160 --> 00:13:03,920 Speaker 1: just watch it over time disappear. So, yeah, that's what 223 00:13:04,000 --> 00:13:05,960 Speaker 1: happens out in the open. So for this reason, if 224 00:13:05,960 --> 00:13:07,640 Speaker 1: you want to turn into a fossil, if you want 225 00:13:07,640 --> 00:13:09,720 Speaker 1: to be preserved, you want to be in a sediment 226 00:13:09,880 --> 00:13:12,720 Speaker 1: forming environment. That would be an area like the bottom 227 00:13:12,760 --> 00:13:15,360 Speaker 1: of the sea floor, where there's a good deposition of 228 00:13:15,400 --> 00:13:18,200 Speaker 1: sediment on top of you. And this is one reason 229 00:13:18,280 --> 00:13:20,840 Speaker 1: you're going to see way more fossils of water dwelling 230 00:13:20,880 --> 00:13:24,400 Speaker 1: animals than you do of land dwelling animals. But rapid 231 00:13:24,400 --> 00:13:27,680 Speaker 1: burial can also happen in some other situations, for example, 232 00:13:27,800 --> 00:13:30,560 Speaker 1: on land where there are sand dunes and the desert 233 00:13:30,640 --> 00:13:33,680 Speaker 1: that might quickly bury an animal body that you know, 234 00:13:33,720 --> 00:13:36,200 Speaker 1: if a sand dune collapses or gets blown by wind 235 00:13:36,280 --> 00:13:38,760 Speaker 1: over the body or in an area where some kind 236 00:13:38,760 --> 00:13:42,720 Speaker 1: of moving water flow. Alluvial areas can wash sediment over 237 00:13:42,720 --> 00:13:46,040 Speaker 1: the body and bury it that way. Of course, over time, 238 00:13:46,080 --> 00:13:48,640 Speaker 1: we know what happens to sediment under pressure. It gets 239 00:13:48,679 --> 00:13:53,720 Speaker 1: turned into rocks and solidified in various ways. But even 240 00:13:53,800 --> 00:13:56,880 Speaker 1: if an organism is quickly buried, that doesn't necessarily mean 241 00:13:56,960 --> 00:13:58,880 Speaker 1: it's going to turn into a fossil. Then you you've 242 00:13:58,920 --> 00:14:01,280 Speaker 1: still got a few hurdles, one of which is that 243 00:14:01,360 --> 00:14:05,719 Speaker 1: it has to undergo some geological transformation. When you come 244 00:14:05,760 --> 00:14:11,400 Speaker 1: across dinosaur bones in the museum, they're not really the 245 00:14:11,440 --> 00:14:14,679 Speaker 1: bones of the dinosaur that you're looking at. What what 246 00:14:14,760 --> 00:14:18,800 Speaker 1: you're looking at as a kind of geological photocopy in 247 00:14:18,840 --> 00:14:22,160 Speaker 1: a sense. Uh So. One of the processes by which 248 00:14:22,200 --> 00:14:25,760 Speaker 1: this happens is known as per mineralization. And this is 249 00:14:25,800 --> 00:14:31,080 Speaker 1: when you've got groundwater that trickles around and through a dead, 250 00:14:31,200 --> 00:14:34,800 Speaker 1: buried organism, and as it trickles through the organism, it 251 00:14:34,840 --> 00:14:38,000 Speaker 1: carries these minerals with it, dissolved minerals in the water 252 00:14:38,960 --> 00:14:41,800 Speaker 1: and leave some of them behind. So the mineral laden 253 00:14:41,800 --> 00:14:45,280 Speaker 1: water fills all these little microscopic gaps and pores in 254 00:14:45,360 --> 00:14:48,520 Speaker 1: your bones, and it deposits some of those minerals that 255 00:14:48,560 --> 00:14:51,800 Speaker 1: it carries in those empty spaces, and then over time 256 00:14:51,880 --> 00:14:55,520 Speaker 1: these minerals accumulate and crystallize throughout the structure of the bone, 257 00:14:55,840 --> 00:14:59,600 Speaker 1: essentially turning the bone into a rock in the shape 258 00:14:59,600 --> 00:15:03,120 Speaker 1: of the original bone. I have to admit, like looking 259 00:15:03,200 --> 00:15:05,640 Speaker 1: back on my own history of dinosaurs, I think I 260 00:15:05,680 --> 00:15:08,520 Speaker 1: had a sense of sadness when I learned for the 261 00:15:08,560 --> 00:15:12,880 Speaker 1: first time that dinosaur bones are not actual dinosaur bones, 262 00:15:12,880 --> 00:15:16,360 Speaker 1: that they are their fossils. Of course, it's it's still amazing, 263 00:15:16,560 --> 00:15:19,120 Speaker 1: but but I think I feel like there's there's a 264 00:15:19,120 --> 00:15:21,600 Speaker 1: certain sadness that can sink in when you when you 265 00:15:21,640 --> 00:15:23,720 Speaker 1: first have to realize, oh, this is it's not as 266 00:15:23,800 --> 00:15:27,600 Speaker 1: simple as the bones of the creature that I'm trying 267 00:15:27,600 --> 00:15:30,520 Speaker 1: to imagine. Well, while these processes do go on, I 268 00:15:30,560 --> 00:15:33,120 Speaker 1: can't say for sure that it's like none of the 269 00:15:33,160 --> 00:15:35,800 Speaker 1: original bone is left. I'm not actually sure about that. 270 00:15:36,080 --> 00:15:38,400 Speaker 1: You know, some part of it may remain in in 271 00:15:38,400 --> 00:15:41,280 Speaker 1: the process like per mineralization. Of course, I also have 272 00:15:41,320 --> 00:15:43,600 Speaker 1: to add that when you're at the museum, you're also 273 00:15:44,120 --> 00:15:45,960 Speaker 1: looking at you might be looking at a specimen for 274 00:15:46,000 --> 00:15:49,200 Speaker 1: which and there there is no complete skeleton, and they're like, 275 00:15:49,720 --> 00:15:52,920 Speaker 1: you know, casts created based on projections. And in some 276 00:15:53,120 --> 00:15:56,240 Speaker 1: museums you might go to, especially smaller museums, you might 277 00:15:56,280 --> 00:16:00,800 Speaker 1: be looking at an entire replica as opposed to actual fossls, 278 00:16:00,920 --> 00:16:03,160 Speaker 1: and a good museum will tell you the difference. I mean, 279 00:16:03,400 --> 00:16:06,000 Speaker 1: for example, the American Museum of Natural History in New York. 280 00:16:06,040 --> 00:16:09,680 Speaker 1: I remember going through their big fossil exhibits. They would 281 00:16:09,680 --> 00:16:14,880 Speaker 1: have illustrations alongside the reconstructions that would show you sometimes 282 00:16:14,880 --> 00:16:18,080 Speaker 1: like what part was original and what part was recast. 283 00:16:18,840 --> 00:16:21,400 Speaker 1: So you have this per mineralization process, but then you've 284 00:16:21,400 --> 00:16:24,440 Speaker 1: also got this process known as replacement, and this is 285 00:16:24,680 --> 00:16:28,280 Speaker 1: similar but sort of more more total, more holistic, and 286 00:16:28,440 --> 00:16:32,040 Speaker 1: organism's body is buried and then it disappears because it 287 00:16:32,040 --> 00:16:36,400 Speaker 1: gets decomposed, maybe my microbial life or gets dissolved through 288 00:16:36,480 --> 00:16:40,280 Speaker 1: chemical reactions with the soil or the groundwater gets washed 289 00:16:40,320 --> 00:16:43,120 Speaker 1: away and eroded, and what you're left with is a 290 00:16:43,160 --> 00:16:47,000 Speaker 1: cavity in the ground in the shape of the original structure. 291 00:16:47,040 --> 00:16:49,120 Speaker 1: So you might have like a cavity in the shape 292 00:16:49,440 --> 00:16:52,040 Speaker 1: of a skeleton or a shell or a bone, and 293 00:16:52,080 --> 00:16:55,440 Speaker 1: then this cavity gets filled in with some other mineral, 294 00:16:55,800 --> 00:16:58,960 Speaker 1: creating a sort of mineral cast in the same shape 295 00:16:58,960 --> 00:17:03,000 Speaker 1: as the original organ in structure. Then, of course there 296 00:17:03,000 --> 00:17:07,400 Speaker 1: are other ways. There is for example, carbonization where organisms 297 00:17:07,440 --> 00:17:10,320 Speaker 1: get squeezed between layers of sediment and leave this carbon 298 00:17:10,440 --> 00:17:14,600 Speaker 1: imprint that sometimes happens to like plants and insects. Then 299 00:17:14,640 --> 00:17:17,000 Speaker 1: there would also be resin in casing, which we all 300 00:17:17,040 --> 00:17:19,840 Speaker 1: know from Jurassic Parks seeing the mosquito and the amber. 301 00:17:20,240 --> 00:17:22,399 Speaker 1: Things can be frozen and ice, of course, like we 302 00:17:22,440 --> 00:17:24,760 Speaker 1: see from the previous ice age. You might see a 303 00:17:24,920 --> 00:17:28,679 Speaker 1: mammoth frozen and ice. And then things can be for example, 304 00:17:28,720 --> 00:17:32,399 Speaker 1: buried in tar, like in the tar pits. So there 305 00:17:32,400 --> 00:17:35,040 Speaker 1: are a lot of ways things can be preserved across 306 00:17:35,080 --> 00:17:38,919 Speaker 1: the geological eons. But despite all these different ways that 307 00:17:39,040 --> 00:17:41,760 Speaker 1: it can happen, it doesn't happen that much. Only a 308 00:17:41,880 --> 00:17:46,000 Speaker 1: very small portion of the animals that exist get preserved, 309 00:17:46,200 --> 00:17:48,240 Speaker 1: and then only a small portion of those that get 310 00:17:48,280 --> 00:17:51,480 Speaker 1: preserved actually get found by us. So we have a 311 00:17:51,720 --> 00:17:55,040 Speaker 1: have a very limited sampling of what there once was 312 00:17:55,200 --> 00:17:57,840 Speaker 1: on planet Earth. But another thing to think about is 313 00:17:58,480 --> 00:18:01,800 Speaker 1: not just the scarcity of fossiles, but the process by 314 00:18:01,840 --> 00:18:07,080 Speaker 1: which they're created. It doesn't tend to favor action. You know, 315 00:18:07,200 --> 00:18:10,239 Speaker 1: you're you're not likely to catch a fossil of an 316 00:18:10,280 --> 00:18:14,000 Speaker 1: animal in mid behavior where it's clear what was happening. 317 00:18:14,640 --> 00:18:18,760 Speaker 1: Something was dead, was probably very very often moved around 318 00:18:18,880 --> 00:18:21,960 Speaker 1: by some water currents or something like that, so you 319 00:18:22,000 --> 00:18:24,359 Speaker 1: don't really necessarily get a sense of what was going 320 00:18:24,400 --> 00:18:28,280 Speaker 1: on in this animal's life. Yeah, fossil evidence of feeding 321 00:18:28,280 --> 00:18:31,200 Speaker 1: behavior or any kind of like really key life moments 322 00:18:31,200 --> 00:18:35,400 Speaker 1: are exceedingly rare. And it's that it's always worth remembering 323 00:18:35,720 --> 00:18:39,119 Speaker 1: that the fossil record itself is inherently incomplete. You're not 324 00:18:39,160 --> 00:18:42,880 Speaker 1: gonna never gonna have a complete fossil record because, as 325 00:18:42,880 --> 00:18:46,720 Speaker 1: we've discussed, like the limits of fossilization, that all the 326 00:18:46,720 --> 00:18:48,679 Speaker 1: criteria that have to be met a stand in the 327 00:18:48,720 --> 00:18:51,040 Speaker 1: way of that um And I don't mention this to 328 00:18:51,080 --> 00:18:53,119 Speaker 1: cast doubt on what we have or the you know, 329 00:18:53,280 --> 00:18:55,720 Speaker 1: the visions of the past that we derive from our fossils. 330 00:18:55,920 --> 00:18:57,720 Speaker 1: It's just that we're left to figure out the shape 331 00:18:57,720 --> 00:19:01,320 Speaker 1: of what came before with an in complete jigsaw puzzle 332 00:19:01,359 --> 00:19:04,600 Speaker 1: that has no box right heart of the cover. And 333 00:19:04,600 --> 00:19:07,159 Speaker 1: it's Joe discussed here to begin with, sediment has to 334 00:19:07,200 --> 00:19:10,000 Speaker 1: cover in organisms remains in order for the long fossilization 335 00:19:10,040 --> 00:19:13,960 Speaker 1: process to begin. Most organisms decomposed before this can happen. 336 00:19:14,359 --> 00:19:17,520 Speaker 1: Fossilization odds increase if the organism happens to exist in 337 00:19:17,600 --> 00:19:20,560 Speaker 1: large numbers or lived in and around a sediment. So, 338 00:19:20,600 --> 00:19:24,680 Speaker 1: for instance, trilobytes meet both criteria. Tons of them, they're 339 00:19:24,720 --> 00:19:28,040 Speaker 1: on the ocean floor, They're very well represented in the 340 00:19:28,080 --> 00:19:30,359 Speaker 1: fossil record. Not so great for a lot of these 341 00:19:31,040 --> 00:19:34,000 Speaker 1: great wonderful land predators you'd want to see, Yeah, like 342 00:19:34,040 --> 00:19:36,320 Speaker 1: something like a t rex that that would have been 343 00:19:36,320 --> 00:19:39,520 Speaker 1: an apex predator. I always think of a pyramid, a 344 00:19:39,560 --> 00:19:43,560 Speaker 1: pyramid of bones, okay, and your apex predator is seated 345 00:19:43,640 --> 00:19:46,400 Speaker 1: on a throne at the top of this pyramid. So 346 00:19:47,200 --> 00:19:49,399 Speaker 1: you can only have so many pyramids based on the 347 00:19:50,400 --> 00:19:53,680 Speaker 1: bones and the bodies and the life force of the creatures. 348 00:19:53,760 --> 00:19:56,200 Speaker 1: And so your apex predator that's gonna be a really 349 00:19:56,320 --> 00:19:59,320 Speaker 1: rare fined. Yeah, I mean, the ecology can't support lots 350 00:19:59,400 --> 00:20:01,320 Speaker 1: of them in the place, so there's not that many 351 00:20:01,359 --> 00:20:04,560 Speaker 1: to choose from. And then it's also existing in circumstances 352 00:20:04,560 --> 00:20:07,160 Speaker 1: that make it less likely to get fossilized when it dies, 353 00:20:07,560 --> 00:20:10,040 Speaker 1: right and then you know, and that's why we have 354 00:20:10,359 --> 00:20:13,280 Speaker 1: we have a number of species out there where we're 355 00:20:13,400 --> 00:20:16,320 Speaker 1: basing the entire species on me maybe even just a 356 00:20:16,320 --> 00:20:19,200 Speaker 1: few different bones, you know, or at least an incomplete skeleton. 357 00:20:19,720 --> 00:20:22,320 Speaker 1: And then plus fossils might be set in stone, but 358 00:20:22,400 --> 00:20:25,400 Speaker 1: they're far from impervious. Like all rocks, they can erode, 359 00:20:25,400 --> 00:20:28,480 Speaker 1: they can melt, they can fragment. So even once fossilization occurs, 360 00:20:28,720 --> 00:20:31,120 Speaker 1: that doesn't mean they're gonna last. It also doesn't mean 361 00:20:31,160 --> 00:20:33,679 Speaker 1: that somebody didn't build a church over it at some point. 362 00:20:34,160 --> 00:20:36,240 Speaker 1: And it's now and so you know, it's a UNESCO 363 00:20:36,320 --> 00:20:39,760 Speaker 1: World Heritage Site now, and you'll never get that juicy 364 00:20:40,200 --> 00:20:45,000 Speaker 1: like you know, three t rex of feeding fossil extravaganza 365 00:20:45,160 --> 00:20:48,239 Speaker 1: that's trapped underneath it. You know, there's so even if 366 00:20:48,240 --> 00:20:52,280 Speaker 1: fossilization happens, we might never see it. So even when 367 00:20:52,280 --> 00:20:55,240 Speaker 1: you do wind up with the fossil jigsaw puzzle pieces 368 00:20:55,280 --> 00:20:57,280 Speaker 1: you need, you still have to figure out how they 369 00:20:57,320 --> 00:21:00,000 Speaker 1: fit together. You have to imagine the missing pieces. Uh, 370 00:21:00,000 --> 00:21:03,879 Speaker 1: there's been a long process in which we've continually refined 371 00:21:03,880 --> 00:21:08,280 Speaker 1: our understanding of the form of these dinosaurs. We're still 372 00:21:08,320 --> 00:21:11,119 Speaker 1: continuing to refine our understanding of what they looked like, 373 00:21:11,160 --> 00:21:13,119 Speaker 1: how they behaved. I mean, you look at something like 374 00:21:13,160 --> 00:21:18,600 Speaker 1: the iguanadon the spike thumbed creature, one of the earliest 375 00:21:18,600 --> 00:21:21,960 Speaker 1: dinosaur finds who's got two thumbs and got illustrated in 376 00:21:21,960 --> 00:21:26,440 Speaker 1: a very weird way. Yeah, you look that guy, because 377 00:21:26,440 --> 00:21:30,200 Speaker 1: if you look at those illustrations, the body just changes rapidly. 378 00:21:30,640 --> 00:21:32,720 Speaker 1: T Rex is another one where we've we've had some 379 00:21:32,720 --> 00:21:36,360 Speaker 1: some distinct changes over time and how we interpret its 380 00:21:36,680 --> 00:21:39,840 Speaker 1: bodily positioning and uh, you know, so a lot of 381 00:21:39,880 --> 00:21:42,159 Speaker 1: the time we can only guess at the shape. We 382 00:21:42,200 --> 00:21:44,720 Speaker 1: can form theories about the shape, and the same goes. 383 00:21:45,080 --> 00:21:48,960 Speaker 1: The same holds true for how different prehistoric species would 384 00:21:48,960 --> 00:21:51,879 Speaker 1: have interacted with each other based on their forms and 385 00:21:51,880 --> 00:21:55,959 Speaker 1: the behavior of existing animals. Evidence of dinosaurs feeding, as 386 00:21:55,960 --> 00:21:58,639 Speaker 1: we said, is exceedingly rare, but every so often the 387 00:21:58,680 --> 00:22:01,959 Speaker 1: fossil records record throws us a real hum dinger. They 388 00:22:02,000 --> 00:22:05,720 Speaker 1: give us an action scene preserved in stone. So that 389 00:22:05,880 --> 00:22:07,400 Speaker 1: is what we're gonna be looking at for the rest 390 00:22:07,440 --> 00:22:09,040 Speaker 1: of the episode. But I think we should take a 391 00:22:09,119 --> 00:22:10,920 Speaker 1: quick break first, and when we come back we will 392 00:22:10,960 --> 00:22:18,359 Speaker 1: get into some of these amazing fossil action scenes. All right, 393 00:22:18,400 --> 00:22:21,320 Speaker 1: we're back now, Robert. Before we actually take a look 394 00:22:21,320 --> 00:22:23,840 Speaker 1: at these fossil action scenes, one thing we should keep 395 00:22:23,880 --> 00:22:27,600 Speaker 1: in mind is that we should say again, you can't 396 00:22:27,680 --> 00:22:30,520 Speaker 1: always look at a fossil and know how and where 397 00:22:30,560 --> 00:22:34,159 Speaker 1: an organism died, right because a lot of remains are, 398 00:22:34,240 --> 00:22:37,200 Speaker 1: for example, moved around by water currents before they get 399 00:22:37,200 --> 00:22:40,000 Speaker 1: buried and fossilized. Uh, it might call to mind you 400 00:22:40,040 --> 00:22:45,600 Speaker 1: can imagine like a big alluvial floodwater deposit where a 401 00:22:45,640 --> 00:22:49,000 Speaker 1: bunch of bones get washed into the same place, and 402 00:22:49,040 --> 00:22:51,840 Speaker 1: then you could come along as a future archaeologist and 403 00:22:51,920 --> 00:22:54,520 Speaker 1: dig this up and look like, oh, there was an 404 00:22:54,560 --> 00:22:57,959 Speaker 1: ancient monster battle here, this is where the battlefield was 405 00:22:58,040 --> 00:23:00,760 Speaker 1: and all the creatures fell. But really what you're looking 406 00:23:00,800 --> 00:23:02,919 Speaker 1: at as a place where the bones were moved to 407 00:23:03,119 --> 00:23:04,840 Speaker 1: along a you know, a path, the path of a 408 00:23:04,920 --> 00:23:07,679 Speaker 1: river or or a flood deposit or something like that. 409 00:23:07,800 --> 00:23:10,520 Speaker 1: So we do need to keep in mind that you 410 00:23:10,560 --> 00:23:15,080 Speaker 1: always have to approach a fossil site with skepticism to 411 00:23:15,119 --> 00:23:17,960 Speaker 1: look at the surroundings, to look for clues to figure 412 00:23:18,000 --> 00:23:21,159 Speaker 1: out if what you're looking at is a true, you know, 413 00:23:21,560 --> 00:23:25,879 Speaker 1: institute scene or if it's some something that has been 414 00:23:25,920 --> 00:23:29,159 Speaker 1: altered by the environment or by the behavior of animals 415 00:23:29,240 --> 00:23:31,840 Speaker 1: or something like that. Indeed, keep that in mind at 416 00:23:31,840 --> 00:23:35,479 Speaker 1: all time. So let's go ahead and launch into it here. Uh, 417 00:23:35,480 --> 00:23:37,159 Speaker 1: it's kind of fun to think of this as a 418 00:23:37,200 --> 00:23:39,639 Speaker 1: as a big fight card, like a you know, like 419 00:23:39,680 --> 00:23:42,000 Speaker 1: a like a sort of wrestling term or you know, 420 00:23:42,080 --> 00:23:44,320 Speaker 1: you know, like a boxing wrestling and then a type 421 00:23:44,320 --> 00:23:47,720 Speaker 1: of situation where you you have the card right the 422 00:23:48,480 --> 00:23:51,879 Speaker 1: opening matches, the mid card, and then finally the main event. Robert, 423 00:23:51,920 --> 00:23:55,160 Speaker 1: I think you're more into the fighting arts than I am. Well, 424 00:23:55,520 --> 00:23:58,600 Speaker 1: probably some of the fighting arts, but here we're talking 425 00:23:58,640 --> 00:24:01,760 Speaker 1: about the dinosaurs were fighting arts, and with our first case, 426 00:24:01,800 --> 00:24:04,440 Speaker 1: we're actually gonna we're gonna kick off with just prehistoric 427 00:24:04,640 --> 00:24:08,800 Speaker 1: mammal fighting arts. So it's time to look at the 428 00:24:08,840 --> 00:24:13,639 Speaker 1: showdown of the Colombian mammoths. So these were placed to 429 00:24:13,720 --> 00:24:17,639 Speaker 1: scene epic animals. Colombian mammoths about one point five million 430 00:24:17,720 --> 00:24:20,920 Speaker 1: years ago until around ten to thirteen thousand years ago. 431 00:24:21,280 --> 00:24:24,160 Speaker 1: They lived in North America, stretching down into ice Age 432 00:24:24,160 --> 00:24:28,040 Speaker 1: Central America. And Uh, these things were big. They were 433 00:24:28,040 --> 00:24:31,280 Speaker 1: bigger than their cousins, the wooly mammoths we know about 434 00:24:31,440 --> 00:24:34,280 Speaker 1: the Colombian mammoths could grow up to about thirteen feet 435 00:24:34,320 --> 00:24:38,359 Speaker 1: tall way maybe eight to ten tons or so. And 436 00:24:38,400 --> 00:24:40,360 Speaker 1: so I want to set the scene for how these 437 00:24:40,400 --> 00:24:44,919 Speaker 1: fossils are discovered. In nineteen sixty two, there's some workers 438 00:24:45,000 --> 00:24:48,080 Speaker 1: who are, according to one account I read, installing some 439 00:24:48,160 --> 00:24:50,560 Speaker 1: electric lines, and another account I read they were doing 440 00:24:50,600 --> 00:24:53,240 Speaker 1: some surveying. So I'm not sure what's the true story there, 441 00:24:53,280 --> 00:24:55,879 Speaker 1: but they were out working on a ranch in the 442 00:24:55,920 --> 00:25:00,679 Speaker 1: Nebraska Panhandle. So that's western Nebraska. It's a sparsely populated 443 00:25:00,760 --> 00:25:03,160 Speaker 1: part of the state, but it is a place where 444 00:25:03,200 --> 00:25:06,400 Speaker 1: you can come across some ancient fossils. And near this 445 00:25:06,600 --> 00:25:11,600 Speaker 1: tiny town of Crawford in western Nebraska, they came across 446 00:25:11,760 --> 00:25:15,920 Speaker 1: the leg bone of an extremely large animal, and they 447 00:25:15,960 --> 00:25:19,600 Speaker 1: took this leg bone wrapped in some feedsack to a 448 00:25:19,640 --> 00:25:24,400 Speaker 1: paleontology student named Mike Vorhees who was brought in for excavation. 449 00:25:24,880 --> 00:25:27,160 Speaker 1: Why are you Why are you grinning? Well, and I'm 450 00:25:27,200 --> 00:25:30,360 Speaker 1: just certainly wondering if there's a connection to Jason Vorhees. Yeah, 451 00:25:30,400 --> 00:25:34,239 Speaker 1: well it's spelled differently. This is I e s all right, 452 00:25:34,640 --> 00:25:37,239 Speaker 1: all right, I'll try and force the mental image out 453 00:25:37,280 --> 00:25:39,879 Speaker 1: of my mind. Yeah, but I mean both bone kings 454 00:25:39,880 --> 00:25:43,520 Speaker 1: of a sort. Now vorhes Is brought in and he 455 00:25:43,640 --> 00:25:48,480 Speaker 1: discovered that there was not one, but two male Colombian 456 00:25:48,600 --> 00:25:54,320 Speaker 1: mammoths fossilized together in the same site. Why together, Well, 457 00:25:54,440 --> 00:25:58,399 Speaker 1: it looks like they died fighting each other. As I 458 00:25:58,440 --> 00:26:01,160 Speaker 1: said a minute ago, the columbia In mammoths are related 459 00:26:01,160 --> 00:26:05,040 Speaker 1: to the smaller, more northern dwelling wooly mammoth, and mammoth's 460 00:26:05,080 --> 00:26:07,600 Speaker 1: lived in Europe and Asia since about two point five 461 00:26:07,680 --> 00:26:10,439 Speaker 1: million years ago or so, and they are not the 462 00:26:10,480 --> 00:26:13,080 Speaker 1: ancestors of existing elephants. I think that might be a 463 00:26:13,119 --> 00:26:16,679 Speaker 1: common misconception, but instead their cousins of elephants along a 464 00:26:16,720 --> 00:26:20,720 Speaker 1: different line of elephant like creatures. They're more closely related 465 00:26:20,720 --> 00:26:24,720 Speaker 1: to Asian elephants than to African elephants. And Asian mammoths 466 00:26:24,720 --> 00:26:27,280 Speaker 1: are believed to have migrated to North America over the 467 00:26:27,320 --> 00:26:30,639 Speaker 1: Bearing Straight Land Bridge about one and a half million 468 00:26:30,720 --> 00:26:33,600 Speaker 1: years ago or so, and they had evolved into the 469 00:26:33,640 --> 00:26:36,920 Speaker 1: form we recognize as the Colombian mammoth by about one 470 00:26:36,960 --> 00:26:40,240 Speaker 1: point one million years ago. So they occupied North America, 471 00:26:40,440 --> 00:26:43,520 Speaker 1: stretching down into Central America up to about the southern 472 00:26:43,560 --> 00:26:45,600 Speaker 1: border of Canada, so you can think about them all 473 00:26:45,640 --> 00:26:49,160 Speaker 1: throughout the the United States area on all in the plains. 474 00:26:49,200 --> 00:26:52,440 Speaker 1: I've heard that they've been found, uh, pretty pretty far 475 00:26:52,560 --> 00:26:56,120 Speaker 1: east and pretty far west. Wooly mammoth's tended to live 476 00:26:56,160 --> 00:26:59,760 Speaker 1: farther up north in like Canadia. Canadia, I said it 477 00:26:59,840 --> 00:27:05,080 Speaker 1: you Canada and Alaska. Now, the Columbian mammoths could live 478 00:27:05,200 --> 00:27:08,399 Speaker 1: about seventy or eighty years, so that's a nice lifespan. 479 00:27:08,920 --> 00:27:11,840 Speaker 1: And once they were adults, they really had no natural predators. 480 00:27:11,840 --> 00:27:14,920 Speaker 1: They're huge now. When they were children, of course children. 481 00:27:15,000 --> 00:27:19,360 Speaker 1: The that is that the term for mammoth's juvenile mammoths 482 00:27:19,520 --> 00:27:22,760 Speaker 1: were preyed upon by the standard carnivores of the time, 483 00:27:22,800 --> 00:27:25,159 Speaker 1: maybe sabretooth cats and things like that. I guess it 484 00:27:25,200 --> 00:27:28,320 Speaker 1: would be a calf, right, calf, an elephant calf? Is 485 00:27:28,320 --> 00:27:32,680 Speaker 1: that right? I think that's probably right. We'll go with it. Now, 486 00:27:32,840 --> 00:27:37,240 Speaker 1: mammoths show sexual dimorphism in the tusks, with the males 487 00:27:37,280 --> 00:27:41,280 Speaker 1: having these longer, heavier tusks than the females, and sometimes 488 00:27:41,320 --> 00:27:45,000 Speaker 1: the Columbia tusks could grow up to about sixteen feet long. 489 00:27:45,800 --> 00:27:47,520 Speaker 1: I think about that. This is on an animal with 490 00:27:47,560 --> 00:27:50,479 Speaker 1: a body length and maybe thirteen to fifteen feet. So 491 00:27:50,520 --> 00:27:55,400 Speaker 1: the tusks are these gigantic weapons. And these animals wind 492 00:27:55,400 --> 00:27:58,800 Speaker 1: extinct sometime between thirteen thousand ten thousand years ago, probably 493 00:27:58,880 --> 00:28:02,040 Speaker 1: due to a combination of climate change in human hunting 494 00:28:02,119 --> 00:28:04,119 Speaker 1: that we don't really know for sure. Have you got 495 00:28:04,160 --> 00:28:06,800 Speaker 1: an illustration here? Oh? There it is. Man, look at 496 00:28:06,840 --> 00:28:09,760 Speaker 1: those massive tusks and they're they're kind of hooked in 497 00:28:09,760 --> 00:28:13,719 Speaker 1: inward and they're not uh, not underhanded sloping up, but 498 00:28:13,840 --> 00:28:18,919 Speaker 1: like hooked around like a grasping claw or something. And 499 00:28:18,920 --> 00:28:21,680 Speaker 1: now to get back to the fossil find that young 500 00:28:21,720 --> 00:28:25,800 Speaker 1: paleontologist Mike Vorhees who worked on the excavation in nineteen 501 00:28:25,880 --> 00:28:28,680 Speaker 1: sixty two, he stuck around with the project and there 502 00:28:28,720 --> 00:28:31,520 Speaker 1: was a two thousand six article on NPR News where 503 00:28:31,560 --> 00:28:34,800 Speaker 1: they interviewed him and he was describing the original discovery 504 00:28:35,480 --> 00:28:38,120 Speaker 1: and he said, quote, once we got to the skull, 505 00:28:38,280 --> 00:28:42,640 Speaker 1: it turned out, well, there's one tusk. There's two tusks. Oh, 506 00:28:42,720 --> 00:28:46,960 Speaker 1: three tusks. What's going on here? Even a young student 507 00:28:47,000 --> 00:28:50,200 Speaker 1: realizes that an elephant only has two tusks. So it 508 00:28:50,240 --> 00:28:53,560 Speaker 1: gradually dawned on us that we actually had two animals 509 00:28:53,600 --> 00:28:57,120 Speaker 1: locked in a death struggle and probably the most exciting 510 00:28:57,160 --> 00:28:59,960 Speaker 1: single fossil I've ever seen. Now, Robert, I have attack 511 00:29:00,200 --> 00:29:02,200 Speaker 1: for you a photo of this where you can kind 512 00:29:02,200 --> 00:29:05,600 Speaker 1: of see what's happening here. Now, scientists more recently believed 513 00:29:05,640 --> 00:29:08,520 Speaker 1: that the two mammoths that are fossilized in this scene 514 00:29:08,520 --> 00:29:13,720 Speaker 1: were very likely in this testosterone fueled bull elephant phase, 515 00:29:14,080 --> 00:29:18,440 Speaker 1: each about forty years old, fighting over mating opportunities, and 516 00:29:18,520 --> 00:29:21,200 Speaker 1: it appears they were well matched because the fight led 517 00:29:21,240 --> 00:29:25,440 Speaker 1: to this entanglement of the tusks, which somehow killed them both. 518 00:29:25,520 --> 00:29:29,720 Speaker 1: So you've got the two skeletons locked face to face 519 00:29:29,880 --> 00:29:34,240 Speaker 1: with tusks entwined. One of the mammoth's tusks is gouging 520 00:29:34,320 --> 00:29:36,840 Speaker 1: into the eye socket of the other, so that that 521 00:29:36,840 --> 00:29:40,280 Speaker 1: would make a good what's her name, Wallace book right 522 00:29:40,840 --> 00:29:45,040 Speaker 1: his his eyes gouged. It hurts immensely. Yeah, you this 523 00:29:45,040 --> 00:29:49,440 Speaker 1: this illustration of the skulls and the tusks intertwined like 524 00:29:49,480 --> 00:29:53,240 Speaker 1: this would make a really gnarly tattoo. Yes, it would, 525 00:29:53,640 --> 00:29:56,000 Speaker 1: that would be. Yeah, it's like a metal band album 526 00:29:56,080 --> 00:29:59,480 Speaker 1: cover kind of thing. It's it's for real Now, the 527 00:29:59,560 --> 00:30:02,120 Speaker 1: fight between these two mammoths was probably a lot more 528 00:30:02,200 --> 00:30:06,120 Speaker 1: dangerous than the average mammoth fight, and it's because both 529 00:30:06,160 --> 00:30:09,520 Speaker 1: of these mammoths had one of their tusks broken off 530 00:30:09,680 --> 00:30:13,200 Speaker 1: and thus shortened. And this actually made it more lethal 531 00:30:13,280 --> 00:30:15,520 Speaker 1: than one of these would have normally been because it 532 00:30:15,560 --> 00:30:19,720 Speaker 1: allowed them to get in closer for fighting, and since 533 00:30:19,760 --> 00:30:22,160 Speaker 1: they got in closer than would normally be possible, it 534 00:30:22,240 --> 00:30:25,880 Speaker 1: led to this tangling of the tusks that killed them. Now, 535 00:30:25,920 --> 00:30:28,560 Speaker 1: it's probably the case that their deaths came slowly, or 536 00:30:28,600 --> 00:30:31,120 Speaker 1: at least one of their deaths came slowly, with one 537 00:30:31,160 --> 00:30:33,760 Speaker 1: of the two bowls dying before the other one and 538 00:30:33,800 --> 00:30:37,240 Speaker 1: then pinning into the ground by the face. And in 539 00:30:37,320 --> 00:30:39,400 Speaker 1: this state they would have been unable to reach food 540 00:30:39,480 --> 00:30:43,080 Speaker 1: or water, but also would have been vulnerable to opportunistic scavengers. 541 00:30:43,840 --> 00:30:47,440 Speaker 1: And this, this aggressive fighting between male mammoths can possibly 542 00:30:47,480 --> 00:30:50,480 Speaker 1: be chalked up to the glory of what's known as must. 543 00:30:50,520 --> 00:30:54,360 Speaker 1: There are you familiar with this concept, Robert Musk the 544 00:30:55,360 --> 00:30:58,440 Speaker 1: smell of the scent no, no, no, must, must with 545 00:30:58,520 --> 00:31:01,560 Speaker 1: a thh, not with a kill? A familiar with? Okay? 546 00:31:01,560 --> 00:31:05,000 Speaker 1: So must? Is this kind of this problem? This is 547 00:31:05,000 --> 00:31:06,560 Speaker 1: not the right way to say it, but I want 548 00:31:06,560 --> 00:31:09,960 Speaker 1: to characterize it this way. It's like a recurring murderous 549 00:31:10,080 --> 00:31:14,040 Speaker 1: puberty in male elephants. More literally, what it is is 550 00:31:14,080 --> 00:31:17,920 Speaker 1: a hormonal period lasting up to weeks and even months, 551 00:31:17,920 --> 00:31:21,480 Speaker 1: when a bull elephants body begins to produce about sixty 552 00:31:21,680 --> 00:31:26,280 Speaker 1: times the amount of testosterone normally found in male elephants, 553 00:31:26,760 --> 00:31:30,080 Speaker 1: and during this period, known as the must, bull elephants 554 00:31:30,120 --> 00:31:33,520 Speaker 1: secrete a substance called tempour in from the temporal glands 555 00:31:33,560 --> 00:31:35,400 Speaker 1: on the sides of their head. You can see pictures 556 00:31:35,400 --> 00:31:38,320 Speaker 1: of them where it looks like they're just using some 557 00:31:38,480 --> 00:31:43,040 Speaker 1: gross orange fluid from their temples. Uh. But it also 558 00:31:43,120 --> 00:31:46,280 Speaker 1: alters their regular behavior, so they become much more violent 559 00:31:46,360 --> 00:31:50,360 Speaker 1: and aggressive. Elephants that are that work with humans in 560 00:31:50,400 --> 00:31:53,560 Speaker 1: these periods become much more dangerous to work with. And 561 00:31:53,600 --> 00:31:56,680 Speaker 1: they also emit this noise known as a must the rumble, 562 00:31:57,200 --> 00:31:59,760 Speaker 1: and they can be seen I watched video of this 563 00:32:00,240 --> 00:32:04,720 Speaker 1: doing this display called tusking the ground where they will 564 00:32:04,760 --> 00:32:09,200 Speaker 1: stab their tusks into the soil um and I think 565 00:32:09,200 --> 00:32:11,920 Speaker 1: they're multiple theories on why exactly they do that, but 566 00:32:12,040 --> 00:32:14,600 Speaker 1: it looks pretty threatening. I'm not sure if it's meant 567 00:32:14,600 --> 00:32:17,800 Speaker 1: to look threatening, you know. I I certainly watched the 568 00:32:17,840 --> 00:32:21,680 Speaker 1: number of documentaries detailing elephants, but but I feel like 569 00:32:21,760 --> 00:32:25,520 Speaker 1: most of them tend to focus on the female herds. 570 00:32:25,720 --> 00:32:28,800 Speaker 1: Ye in the matriarchal order there, because you have the 571 00:32:28,800 --> 00:32:32,000 Speaker 1: the elderly females, uh, leading and then you have the 572 00:32:32,040 --> 00:32:34,480 Speaker 1: younger females, and then you have the the young the 573 00:32:34,560 --> 00:32:38,280 Speaker 1: calf's following around. And in the males they live separately. 574 00:32:38,320 --> 00:32:41,760 Speaker 1: And now that you've described their behavior at times, you 575 00:32:41,840 --> 00:32:44,280 Speaker 1: understand why they have to live outside the house, right, 576 00:32:44,320 --> 00:32:46,320 Speaker 1: so when they go into a must period, you just 577 00:32:46,360 --> 00:32:49,160 Speaker 1: don't want to be around them. They're no good uh. 578 00:32:49,200 --> 00:32:52,560 Speaker 1: And so it's it's not unknown actually for for other 579 00:32:52,720 --> 00:32:56,760 Speaker 1: types of animals to engage in these than these mutually 580 00:32:56,880 --> 00:33:01,760 Speaker 1: deadly male dominance encounters. For example, stags sometimes go into 581 00:33:01,760 --> 00:33:05,120 Speaker 1: male dominance conflicts where they get their antlers hopelessly locked. 582 00:33:05,280 --> 00:33:07,560 Speaker 1: You might remember from last year there was the discovery 583 00:33:07,560 --> 00:33:11,680 Speaker 1: of these two bull moose in Una lucklyit Alaska. Oh yeah, 584 00:33:11,800 --> 00:33:14,240 Speaker 1: I think I remember this. Yes, So they're frozen in 585 00:33:14,400 --> 00:33:17,800 Speaker 1: ice with their antlers locked, and it looks like what 586 00:33:17,880 --> 00:33:20,400 Speaker 1: happened in this case was that the two moose were 587 00:33:20,520 --> 00:33:23,320 Speaker 1: in a fight over mating rights, and they got their 588 00:33:23,360 --> 00:33:26,479 Speaker 1: antlers stuck together, and then they drowned, and then the 589 00:33:26,480 --> 00:33:30,480 Speaker 1: water that they drowned in froze. This also happened sometimes 590 00:33:30,480 --> 00:33:32,960 Speaker 1: with male white tailed deer and elk who they have 591 00:33:33,080 --> 00:33:36,600 Speaker 1: these antlers and they locked them together in these dominance displays, 592 00:33:37,080 --> 00:33:40,240 Speaker 1: and sometimes they get their antlers entangled during fights over 593 00:33:40,280 --> 00:33:43,480 Speaker 1: mating and territory, and once they're stuck together, they can 594 00:33:43,520 --> 00:33:47,240 Speaker 1: become exhausted and die and sometimes even be eaten alive 595 00:33:47,400 --> 00:33:51,960 Speaker 1: by coyotes, and their vulnerable state even crazier. Here's another 596 00:33:52,000 --> 00:33:56,560 Speaker 1: thing I came across male dominance entanglement swans. Did you 597 00:33:56,600 --> 00:33:59,560 Speaker 1: see this video? It went viral a while back, but 598 00:33:59,600 --> 00:34:03,600 Speaker 1: there were the two photographers in Latvia named Alexander and 599 00:34:03,680 --> 00:34:08,000 Speaker 1: Vitali drov And in two thousand nine they filmed this 600 00:34:08,120 --> 00:34:11,319 Speaker 1: encounter where they had a pair of swans that were 601 00:34:11,360 --> 00:34:16,440 Speaker 1: just hopelessly entangled by the wings and necks, floating pathetically 602 00:34:16,480 --> 00:34:20,160 Speaker 1: in a pond, just kind of paddling around randomly, looking 603 00:34:20,200 --> 00:34:23,279 Speaker 1: on the verge of death, and the two men came 604 00:34:23,360 --> 00:34:25,680 Speaker 1: up to them. I from what I've read, by the way, 605 00:34:25,800 --> 00:34:29,040 Speaker 1: don't don't try this because swans can actually be very 606 00:34:29,080 --> 00:34:34,000 Speaker 1: aggressive and dangerous. Yeah, so don't try to mess with swans. 607 00:34:34,040 --> 00:34:37,120 Speaker 1: But the two men were unable to untie the knot 608 00:34:37,200 --> 00:34:40,799 Speaker 1: of birdnecks and wings and the two swans, you would 609 00:34:40,800 --> 00:34:42,520 Speaker 1: you'd have to see it. It's crazy. They are in 610 00:34:42,560 --> 00:34:46,279 Speaker 1: a knot. They're just completely twisted around each other. And 611 00:34:46,400 --> 00:34:48,839 Speaker 1: once they finally get all this stuff untangled, the two 612 00:34:48,920 --> 00:34:52,520 Speaker 1: swans just scramble away, and without this intervention, it looks 613 00:34:52,560 --> 00:34:55,120 Speaker 1: like they probably would have died. But in a National 614 00:34:55,160 --> 00:34:59,680 Speaker 1: Geographic article about this incident, the Smithsonian Natural History Museum 615 00:34:59,680 --> 00:35:02,920 Speaker 1: bird expert Brian K. Schmidt says that they were probably 616 00:35:02,960 --> 00:35:07,600 Speaker 1: also male swans who were fighting overbreeding territory. So with 617 00:35:07,880 --> 00:35:11,440 Speaker 1: all these animals, from swans to stags to mammoths, it 618 00:35:11,520 --> 00:35:14,960 Speaker 1: often probably doesn't come to a physical fight, right, and 619 00:35:15,040 --> 00:35:17,440 Speaker 1: two males are going to be making threatening displays at 620 00:35:17,480 --> 00:35:19,799 Speaker 1: one another and then the less dominant one is going 621 00:35:19,840 --> 00:35:22,719 Speaker 1: to run away. But sometimes this doesn't happen in the 622 00:35:22,719 --> 00:35:26,600 Speaker 1: situation escalates into this genuine battle of strength, and I 623 00:35:26,680 --> 00:35:29,759 Speaker 1: just think it's kind of odds is a strange poeticism 624 00:35:29,760 --> 00:35:32,960 Speaker 1: to it that there's this tendency of male animals across 625 00:35:33,040 --> 00:35:36,440 Speaker 1: all these different classes of life to put up fighting 626 00:35:36,440 --> 00:35:39,560 Speaker 1: displays for the right to mate with females, only to 627 00:35:39,719 --> 00:35:42,560 Speaker 1: end up in an eternal death embrace with their enemy 628 00:35:42,600 --> 00:35:47,839 Speaker 1: and usurper. Yeah, to remove them from themselves from competition. Yeah, 629 00:35:47,880 --> 00:35:51,239 Speaker 1: for the for the thing that they're after feels somehow metaphorical. 630 00:35:52,280 --> 00:35:54,360 Speaker 1: Well that is, that is one heck of an encounter. 631 00:35:54,960 --> 00:35:56,239 Speaker 1: It's one of these where you can look at you 632 00:35:56,239 --> 00:35:58,960 Speaker 1: can look at the fossil evidence you can, and then 633 00:35:59,000 --> 00:36:03,040 Speaker 1: you can imagine conflict and and just just see these 634 00:36:03,640 --> 00:36:07,279 Speaker 1: behemoths locked up with each other and just battling to 635 00:36:07,320 --> 00:36:09,759 Speaker 1: the death. Yeah. It's also kind of sad though, to 636 00:36:09,800 --> 00:36:12,000 Speaker 1: imagine what they looked like once they were on the ground, 637 00:36:12,200 --> 00:36:15,600 Speaker 1: maybe once one of them has died and they're just stuck. Yeah, 638 00:36:15,719 --> 00:36:18,719 Speaker 1: I don't know. It's an ignominious end for a for 639 00:36:18,760 --> 00:36:22,120 Speaker 1: a powerful beast. I agree. Well, you know, if that, 640 00:36:22,400 --> 00:36:24,960 Speaker 1: if that's the story of an end, I think we 641 00:36:25,000 --> 00:36:28,800 Speaker 1: should discuss the story of a beginning. So we're on 642 00:36:28,840 --> 00:36:31,319 Speaker 1: the lower still on the lower card here, so it's 643 00:36:31,360 --> 00:36:34,760 Speaker 1: time to you know, we can include some some fossil 644 00:36:34,840 --> 00:36:38,640 Speaker 1: action scenes that are less combative in nature. Well, I 645 00:36:38,640 --> 00:36:41,799 Speaker 1: should hope, so come on, yeah, because certainly bring the peace, 646 00:36:41,800 --> 00:36:44,839 Speaker 1: love and understanding. Yeah, because the animal interactions don't have 647 00:36:44,960 --> 00:36:48,160 Speaker 1: to include violence. They can of course include mating. They 648 00:36:48,160 --> 00:36:52,040 Speaker 1: can also include birth itself or or the the care 649 00:36:52,080 --> 00:36:54,640 Speaker 1: for young. Right, And that's why we turn now to 650 00:36:54,800 --> 00:36:58,960 Speaker 1: the it feels saurus all right, Yes, And what we're 651 00:36:59,000 --> 00:37:02,719 Speaker 1: dealing with here is it the osaurus live birth. And 652 00:37:02,800 --> 00:37:05,680 Speaker 1: this this now blew me away when I've heard about it. 653 00:37:05,920 --> 00:37:09,000 Speaker 1: Here's something that's interesting to me. I didn't know that 654 00:37:09,200 --> 00:37:12,440 Speaker 1: I theosaurs would have live offspring. I just would have 655 00:37:12,480 --> 00:37:14,879 Speaker 1: assumed they laid eggs because it seems like they're sort 656 00:37:14,880 --> 00:37:19,640 Speaker 1: of half reptile half fish, both of which lay eggs. Right. Yeah, 657 00:37:19,719 --> 00:37:22,520 Speaker 1: And we and certainly when we think of aquatic reptiles, 658 00:37:22,600 --> 00:37:26,480 Speaker 1: we think of existing examples that are the very sea turtles, who, 659 00:37:26,719 --> 00:37:29,600 Speaker 1: as as as I think most of us know, have 660 00:37:29,760 --> 00:37:31,920 Speaker 1: to return to shore to lay their eggs and then 661 00:37:31,960 --> 00:37:35,759 Speaker 1: go back to sea. So what we're dealing with here 662 00:37:35,800 --> 00:37:40,960 Speaker 1: are are athosaurs, in many cases specifically the Ichthyosaurus. There 663 00:37:40,960 --> 00:37:44,360 Speaker 1: are several varieties. The time here is early Jurassic to 664 00:37:44,480 --> 00:37:49,680 Speaker 1: early Cretaceous. Location Europe Greenland and North America and these uh, 665 00:37:49,880 --> 00:37:53,240 Speaker 1: these specimen. These organisms were generally up to six ft 666 00:37:53,320 --> 00:37:57,480 Speaker 1: six inches long or two ms long. So the athosaurs 667 00:37:57,520 --> 00:38:01,320 Speaker 1: were the fish lizards the name applies. They were indeed 668 00:38:01,480 --> 00:38:05,839 Speaker 1: highly specialized marine reptiles. They ruled the seas, ranging far 669 00:38:05,920 --> 00:38:09,359 Speaker 1: and wide throughout the early Triassic times for roughly one 670 00:38:09,840 --> 00:38:13,279 Speaker 1: million years. I love these guys and I actually have 671 00:38:13,320 --> 00:38:16,439 Speaker 1: a bumper sticker on my car of of one done 672 00:38:16,440 --> 00:38:20,560 Speaker 1: by the local Atlanta artists our land. Uh it I 673 00:38:20,600 --> 00:38:23,800 Speaker 1: interpreted as an ichthiosaura. It might just be a funky dolphin. 674 00:38:24,680 --> 00:38:27,239 Speaker 1: But but but I see it, and I think, knowing 675 00:38:27,239 --> 00:38:31,120 Speaker 1: our lands, I have googly eyes. It does have strange eyes. 676 00:38:32,400 --> 00:38:35,600 Speaker 1: But you know, the funky dolphin thing is is is 677 00:38:35,640 --> 00:38:38,040 Speaker 1: apt because indeed, when you look at a skeleton or 678 00:38:38,120 --> 00:38:42,279 Speaker 1: certainly a work of paleo art, the Ichthyosaurus does look 679 00:38:42,360 --> 00:38:45,400 Speaker 1: very much like a weird dolphin, and paleontologists believed they 680 00:38:45,400 --> 00:38:49,440 Speaker 1: would have probably occupied the same ecological niche uh. The 681 00:38:49,480 --> 00:38:52,640 Speaker 1: origins are unclear, but they likely evolved from a land 682 00:38:52,680 --> 00:38:56,000 Speaker 1: reptile rather than another aquatic one. That is really interesting. 683 00:38:56,040 --> 00:38:58,960 Speaker 1: Of course, now we know that these these marine mammals 684 00:38:59,000 --> 00:39:02,239 Speaker 1: evolved probably from land dwelling mammals. Right, They were land 685 00:39:02,280 --> 00:39:05,600 Speaker 1: dwelling mammals that moved back into the water. And now 686 00:39:05,640 --> 00:39:09,080 Speaker 1: we see the same thing happen with reptiles, but earlier. Yeah, 687 00:39:09,320 --> 00:39:12,600 Speaker 1: it's mind blowing to see the evolution of a basic 688 00:39:12,680 --> 00:39:15,440 Speaker 1: form across a different species. So you have, you know, 689 00:39:15,480 --> 00:39:18,600 Speaker 1: the shark, the tune of the dolphin, the athosaurs. It 690 00:39:18,640 --> 00:39:21,600 Speaker 1: makes me wonder if you know, some distant water world 691 00:39:21,640 --> 00:39:25,880 Speaker 1: on another planet, Uh, you're gonna have creatures that are 692 00:39:26,080 --> 00:39:28,440 Speaker 1: very different in many respects but still end up taking 693 00:39:28,480 --> 00:39:32,080 Speaker 1: the basic form of the athiosaur or the dolphin. Yeah, 694 00:39:32,120 --> 00:39:36,680 Speaker 1: it seems widely successful. So we talked earlier about you know, 695 00:39:36,719 --> 00:39:40,360 Speaker 1: the what helps a creature become a fossil if it 696 00:39:40,400 --> 00:39:42,320 Speaker 1: lives in the water, but it lives in a near sediment, 697 00:39:42,320 --> 00:39:45,839 Speaker 1: and if it's around insufficient numbers and the ethos are 698 00:39:45,960 --> 00:39:48,520 Speaker 1: definitely lines up with this. It's an animal that we 699 00:39:48,600 --> 00:39:51,640 Speaker 1: know very well from the fossil record, based on several 700 00:39:51,800 --> 00:39:57,320 Speaker 1: hundred complete skeletons, many stemming from early Jurassic fossils recorded 701 00:39:57,320 --> 00:40:01,520 Speaker 1: in shallow waters now shale in southern Germany. And and 702 00:40:01,600 --> 00:40:05,640 Speaker 1: these are these are some excellent fossils because in many 703 00:40:05,680 --> 00:40:09,360 Speaker 1: cases there's a thin film of carbon around them that 704 00:40:09,480 --> 00:40:13,880 Speaker 1: indicates the exact shape of their bodies while they had flesh. 705 00:40:14,000 --> 00:40:15,719 Speaker 1: So so it's not just a matter of you know, 706 00:40:16,000 --> 00:40:18,680 Speaker 1: when you look at some of the dinosaurs uh skeletons, 707 00:40:18,680 --> 00:40:21,520 Speaker 1: you'll see varying theories about like, well, maybe this one 708 00:40:21,600 --> 00:40:25,719 Speaker 1: had some sort of um like an inflatable growth on 709 00:40:25,800 --> 00:40:29,360 Speaker 1: its head, especially with the duck build dinosaurs, or just 710 00:40:29,360 --> 00:40:32,359 Speaker 1: stuff about skin texture and feathers and things like that. Yeah, 711 00:40:32,400 --> 00:40:35,240 Speaker 1: we don't always have enough fossil events to really fully 712 00:40:35,239 --> 00:40:38,920 Speaker 1: imagine the flesh, but with the atheosaurs we do. We 713 00:40:38,960 --> 00:40:41,879 Speaker 1: have this carnibon outline that tells us the shape they 714 00:40:41,920 --> 00:40:45,319 Speaker 1: had in life. We also have a fossilized poop or 715 00:40:45,600 --> 00:40:49,000 Speaker 1: corporate lights. We have the stomach contents in some cases, 716 00:40:49,160 --> 00:40:52,520 Speaker 1: so we know what they ate, mostly fish and some cephalopods, 717 00:40:52,600 --> 00:40:55,560 Speaker 1: and we even have remnants of pigment cells to suggest 718 00:40:55,600 --> 00:41:00,319 Speaker 1: a dark reddish brown colorization. Now you might be well, 719 00:41:00,360 --> 00:41:02,200 Speaker 1: whine with an animal that lives in the water or 720 00:41:02,200 --> 00:41:04,520 Speaker 1: want to have like a dark ruddy, you know, kind 721 00:41:04,520 --> 00:41:07,600 Speaker 1: of color, And there there's a theory that they may 722 00:41:07,640 --> 00:41:11,240 Speaker 1: have used this dark colouration to to heat up rapidly 723 00:41:11,360 --> 00:41:16,279 Speaker 1: between deep dives into the cool depths for fish. Whoa, yeah, 724 00:41:16,320 --> 00:41:19,680 Speaker 1: so again, they basically had the same role as a 725 00:41:19,719 --> 00:41:23,040 Speaker 1: modern dolphin, and paleontologist believed they may have become extinct 726 00:41:23,200 --> 00:41:27,400 Speaker 1: due to later competition with the increasingly advanced sharks of 727 00:41:27,440 --> 00:41:31,680 Speaker 1: the cretation. Now that's funny because I love sharks, but 728 00:41:31,719 --> 00:41:34,680 Speaker 1: it's hard for me to think of sharks as advanced. Well, 729 00:41:34,920 --> 00:41:36,480 Speaker 1: this was a time when they were. They were the 730 00:41:36,520 --> 00:41:38,600 Speaker 1: hot new model. Yeah, I mean, it seems like they 731 00:41:38,600 --> 00:41:41,720 Speaker 1: are the dinosaurs now, I mean so yeah, it's certainly 732 00:41:41,800 --> 00:41:44,480 Speaker 1: we do have these amazing prehistoric sharks, right, I mean 733 00:41:45,760 --> 00:41:49,400 Speaker 1: the Megalodon, krotoxy Ryan and all these. But this was 734 00:41:49,440 --> 00:41:52,720 Speaker 1: a time when the atostars ruled the world, the world 735 00:41:52,719 --> 00:41:55,880 Speaker 1: the seas for for this long stretch of time. But 736 00:41:55,960 --> 00:41:59,960 Speaker 1: then the sharks got more advanced and they likely outcompete 737 00:42:00,040 --> 00:42:02,799 Speaker 1: them for resources. Now, one cool thing about the ichthyosaur 738 00:42:03,400 --> 00:42:05,920 Speaker 1: is that if it's occupying a similar to the dolphin 739 00:42:05,960 --> 00:42:07,680 Speaker 1: and it evolved for the same way, it's probably not 740 00:42:07,719 --> 00:42:10,080 Speaker 1: going to be a gill breathing organism, right, but it's 741 00:42:10,080 --> 00:42:13,719 Speaker 1: an air breathing organism. Right. Yeah, everyone agrees they were 742 00:42:13,760 --> 00:42:16,920 Speaker 1: air breathers, there's no getting around that. But they seem 743 00:42:16,960 --> 00:42:19,960 Speaker 1: to get around the necessity of returning to shore to 744 00:42:20,080 --> 00:42:22,680 Speaker 1: lay their eggs as other uh you know, extinct and 745 00:42:22,680 --> 00:42:26,719 Speaker 1: existing marine animals, marine reptiles must And that's where the 746 00:42:26,760 --> 00:42:29,440 Speaker 1: action packed fossil comes into play. Not a fossilized bit 747 00:42:29,480 --> 00:42:34,560 Speaker 1: of combat, but a seemingly fossilized live birth whole, or 748 00:42:34,560 --> 00:42:37,000 Speaker 1: at least that's what the fossil evidence suggests. So there's 749 00:42:37,000 --> 00:42:39,359 Speaker 1: there's been some debate in the past on whether this 750 00:42:39,600 --> 00:42:43,200 Speaker 1: might have been near stomach contents. Uh. You run into 751 00:42:43,239 --> 00:42:46,720 Speaker 1: similar cases of interpretation, like you have some some bodies 752 00:42:46,760 --> 00:42:50,080 Speaker 1: grouped together. Is there just it's just just some accidental 753 00:42:50,239 --> 00:42:53,920 Speaker 1: overlay here, Um, what's going on when we look at 754 00:42:53,960 --> 00:42:56,759 Speaker 1: these But the consensus now seems to be that that 755 00:42:56,840 --> 00:43:00,239 Speaker 1: we do have fossil evidence of embryos and live earth 756 00:43:00,680 --> 00:43:04,120 Speaker 1: sometimes scattered outside of the body. And there's some discussion 757 00:43:04,400 --> 00:43:07,200 Speaker 1: over whether this was due to explosion after death, like 758 00:43:07,239 --> 00:43:10,840 Speaker 1: the body bloats up and then burst right. Um. Early 759 00:43:10,960 --> 00:43:13,920 Speaker 1: arguments that they might have given birth on land gave 760 00:43:14,000 --> 00:43:17,239 Speaker 1: way to uh an aquatic consensus at least with the 761 00:43:18,040 --> 00:43:21,520 Speaker 1: with with with many of the athios are species, evidence 762 00:43:21,560 --> 00:43:24,840 Speaker 1: shows that they were born tail first to prevent drowning 763 00:43:25,080 --> 00:43:29,880 Speaker 1: breach by nature. Now this being said, In two thousand fourteen, 764 00:43:30,280 --> 00:43:35,040 Speaker 1: uh Ryosuki Motani of the University of California Davis and 765 00:43:35,160 --> 00:43:39,319 Speaker 1: colleagues published research concluding that a fossil i specimen of 766 00:43:39,400 --> 00:43:43,560 Speaker 1: the athiosaur Chao Hu sais this is the oldest of 767 00:43:43,880 --> 00:43:47,480 Speaker 1: Mesozoic marine reptiles that lived approximately two forty eight million 768 00:43:47,560 --> 00:43:51,919 Speaker 1: years ago. Uh They showed that the partial skeleton which 769 00:43:51,960 --> 00:43:54,840 Speaker 1: was recovered in China may show a live birth. It 770 00:43:54,880 --> 00:43:59,040 Speaker 1: features three embryos and neonates, one inside the mother, another 771 00:43:59,160 --> 00:44:02,320 Speaker 1: exiting the pell us, with half the body still inside 772 00:44:02,320 --> 00:44:05,560 Speaker 1: the mother, and the third outside. Interestingly enough to study 773 00:44:05,560 --> 00:44:08,320 Speaker 1: concluded that these specimens might have given birth on dry 774 00:44:08,480 --> 00:44:11,440 Speaker 1: land due to the head first positioning of the emerging 775 00:44:11,520 --> 00:44:15,040 Speaker 1: young So this would have been an older example. So 776 00:44:15,080 --> 00:44:19,600 Speaker 1: we can imagine how how this might have developed into 777 00:44:19,640 --> 00:44:24,080 Speaker 1: the full uh at sea live birth that the majority 778 00:44:24,120 --> 00:44:28,280 Speaker 1: of the atheosaurs engaged in. God, it's crazy to imagine 779 00:44:30,320 --> 00:44:32,520 Speaker 1: that this must not be all that weird for the 780 00:44:32,560 --> 00:44:35,400 Speaker 1: majority of life on Earth. But but I don't know. 781 00:44:35,719 --> 00:44:39,800 Speaker 1: All doing all of the life stuff, mating, giving birth, 782 00:44:39,920 --> 00:44:42,759 Speaker 1: all in this marine environment with nothing to grab a 783 00:44:42,760 --> 00:44:46,399 Speaker 1: hold of. I mean, and it's crazy to think too, 784 00:44:46,400 --> 00:44:49,120 Speaker 1: that this is a form that evolved from a terrestrial creature. 785 00:44:50,239 --> 00:44:53,400 Speaker 1: You basically encounted the same, the same blocks, the same, 786 00:44:56,360 --> 00:44:59,719 Speaker 1: the same struggle to try and imagine, uh, just the 787 00:45:00,080 --> 00:45:03,560 Speaker 1: the scope of evolution over the course of time periods 788 00:45:03,600 --> 00:45:06,760 Speaker 1: that humans just simply did not evolve to fathom totally. 789 00:45:06,840 --> 00:45:08,799 Speaker 1: Now I've got another one for you, Robert, in the 790 00:45:08,840 --> 00:45:12,200 Speaker 1: same scope, getting away from the fighting more towards the 791 00:45:12,239 --> 00:45:15,840 Speaker 1: reproduction and nurture. Uh, this one's gonna be short, but 792 00:45:16,320 --> 00:45:21,160 Speaker 1: in a group of German scientists reported, I thought this 793 00:45:21,239 --> 00:45:25,080 Speaker 1: was amazing, the first known find of a pair of 794 00:45:25,239 --> 00:45:30,000 Speaker 1: vertebrate animals fossilized in the active mating. So it's a 795 00:45:30,000 --> 00:45:33,080 Speaker 1: pair of turtles from about fifty million years ago or so. 796 00:45:33,760 --> 00:45:36,360 Speaker 1: It's described in the article Caught in the Act, the 797 00:45:36,440 --> 00:45:41,120 Speaker 1: first record of copulating fossil vertebrates by Walter G. Joyce 798 00:45:41,200 --> 00:45:45,319 Speaker 1: at All in Biology Letters in and these turtles were 799 00:45:45,320 --> 00:45:49,200 Speaker 1: discovered in the Eocene Messil Pit fossil site in Germany, 800 00:45:49,239 --> 00:45:51,960 Speaker 1: which is a site of an ancient lake that's produced 801 00:45:52,000 --> 00:45:55,920 Speaker 1: tons of fossils, and the turtles in question were Aliachellis 802 00:45:56,000 --> 00:45:59,160 Speaker 1: crassus sculpta, an example of what's known as the pig 803 00:45:59,200 --> 00:46:04,319 Speaker 1: nosed turtle, and the authors used the fact that the 804 00:46:04,360 --> 00:46:08,120 Speaker 1: two turtles died in the coital position to infer something 805 00:46:08,160 --> 00:46:10,279 Speaker 1: interesting about the lake, or at least this was their 806 00:46:10,320 --> 00:46:13,960 Speaker 1: their conclusion. Not everybody agrees with it. But when these 807 00:46:13,960 --> 00:46:17,360 Speaker 1: types of turtles mate, the smaller male mounts up on 808 00:46:17,440 --> 00:46:21,359 Speaker 1: top of the back of the larger female, and once 809 00:46:21,400 --> 00:46:25,040 Speaker 1: they're in the copulation position, they tend to sort of freeze. 810 00:46:25,560 --> 00:46:27,759 Speaker 1: They just sort of stopped moving around and they do 811 00:46:27,800 --> 00:46:31,200 Speaker 1: their thing and they're frozen in position. Now, of course, 812 00:46:31,560 --> 00:46:34,080 Speaker 1: if they're frozen in position and it happens out in 813 00:46:34,160 --> 00:46:37,640 Speaker 1: open water, the couple of turtles will tend to sink 814 00:46:37,880 --> 00:46:42,279 Speaker 1: down into the water during the mating process. And what 815 00:46:42,360 --> 00:46:44,920 Speaker 1: the authors de do is is that the mating began 816 00:46:45,160 --> 00:46:49,120 Speaker 1: on the surface waters which were inhabitable fine, and then 817 00:46:49,680 --> 00:46:52,919 Speaker 1: sank down into the abyss hole section of the lake, 818 00:46:53,080 --> 00:46:57,279 Speaker 1: which they hypothesized was toxic. And this is their explanation 819 00:46:57,400 --> 00:47:00,239 Speaker 1: for why this lake has produced so many fossils. That 820 00:47:00,680 --> 00:47:03,719 Speaker 1: that the abyssle section of the lake is has some 821 00:47:03,800 --> 00:47:06,760 Speaker 1: kind of dissolved I think they were talking about dissolved 822 00:47:06,760 --> 00:47:09,520 Speaker 1: CEO two that would be toxic to animals that have 823 00:47:09,640 --> 00:47:12,879 Speaker 1: some kind of respiration quality in their skin. And so 824 00:47:13,000 --> 00:47:16,520 Speaker 1: as the mating pair sank lower during mating, their skin 825 00:47:16,560 --> 00:47:19,800 Speaker 1: absorbed poisons and they died in the act, only to 826 00:47:19,880 --> 00:47:22,919 Speaker 1: be buried and fossilized in the sediment below and now 827 00:47:23,360 --> 00:47:26,640 Speaker 1: pointed and then laughed at by everyone. Well, I like 828 00:47:26,680 --> 00:47:29,280 Speaker 1: how this this story starts out feeling like a James 829 00:47:29,280 --> 00:47:32,360 Speaker 1: Bond love sequence, like from Russia with love needs to 830 00:47:32,400 --> 00:47:34,799 Speaker 1: be playing over, you know, Da da da da da, 831 00:47:35,480 --> 00:47:40,440 Speaker 1: and then it turns deadly. Yeah, as it always does. Uh, 832 00:47:40,480 --> 00:47:42,520 Speaker 1: But yeah, I thought that's kind of interesting. You can 833 00:47:42,520 --> 00:47:44,600 Speaker 1: look up the picture of the two turtles. They are 834 00:47:45,960 --> 00:47:50,239 Speaker 1: joined in their fossilized state, uh, and it's kind of 835 00:47:50,280 --> 00:47:53,000 Speaker 1: an interesting thing to look at. So yeah, as turtles 836 00:47:53,120 --> 00:47:56,200 Speaker 1: mating always always are. If you ever go to the zoo, 837 00:47:56,280 --> 00:47:59,560 Speaker 1: you you may encounter mating turtles, and it's all it's 838 00:47:59,560 --> 00:48:03,520 Speaker 1: always worth gazing at and listening to because it's generally 839 00:48:03,600 --> 00:48:06,239 Speaker 1: there's a lot of grunting involved. I'm not sure have 840 00:48:06,360 --> 00:48:10,280 Speaker 1: you seen the YouTube videos of turtles trying to mate 841 00:48:10,320 --> 00:48:14,120 Speaker 1: with various objects such as shoes and bowls. No, I 842 00:48:14,160 --> 00:48:16,560 Speaker 1: have not. Yeah, they tend to make a kind of 843 00:48:16,600 --> 00:48:21,160 Speaker 1: squeaking sound that's cute. I will have to look those up. 844 00:48:21,360 --> 00:48:23,000 Speaker 1: All Right, we're gonna take a quick break and when 845 00:48:23,000 --> 00:48:30,720 Speaker 1: we come back, we're going to get back into the combat. Alright, 846 00:48:30,719 --> 00:48:35,040 Speaker 1: we're back, So we're finally going to get back into 847 00:48:35,040 --> 00:48:37,120 Speaker 1: the combat, and we're going to get back to the 848 00:48:37,440 --> 00:48:40,080 Speaker 1: to some of the dinosaurs that everyone's properly familiar with. 849 00:48:40,200 --> 00:48:42,399 Speaker 1: You've been itching for a fight, haven't you. Yes, I have. 850 00:48:42,880 --> 00:48:47,080 Speaker 1: And enough enough of this love, enough of this reproduction 851 00:48:47,160 --> 00:48:49,960 Speaker 1: and birth. Yeah, and we're definitely in terms of the 852 00:48:49,960 --> 00:48:53,680 Speaker 1: big fight card. We're into the upper mid card now, 853 00:48:54,200 --> 00:48:57,400 Speaker 1: so it's time for some really hard hitting action. And 854 00:48:57,440 --> 00:49:00,480 Speaker 1: when you when you think about dinosaur combat, there are 855 00:49:00,520 --> 00:49:02,360 Speaker 1: a few names that are gonna be on that list, 856 00:49:02,719 --> 00:49:06,320 Speaker 1: and I guarantee for most people, I mean, for modern listeners, 857 00:49:06,360 --> 00:49:08,239 Speaker 1: this one might even be up at the top, but 858 00:49:08,280 --> 00:49:10,880 Speaker 1: I think it's probably two or three, maybe four, and 859 00:49:10,920 --> 00:49:15,480 Speaker 1: that is the Velociraptor. Now, I wonder if wasn't there 860 00:49:15,600 --> 00:49:18,799 Speaker 1: some TV show that does these historical matchups where it's 861 00:49:18,840 --> 00:49:21,800 Speaker 1: like who would win in a fight between a velociraptor 862 00:49:22,280 --> 00:49:26,759 Speaker 1: and a medieval night Probably there was some show like 863 00:49:26,840 --> 00:49:29,200 Speaker 1: this wasn't there, so it sounds like something that would 864 00:49:29,239 --> 00:49:34,919 Speaker 1: be on that I didn't watch. Samurai versus Velociraptor. Well, 865 00:49:35,800 --> 00:49:39,960 Speaker 1: advantage probably goes to the velociraptor. Just just off the 866 00:49:39,960 --> 00:49:42,560 Speaker 1: top of my head without really crunching with data. Uh, 867 00:49:42,719 --> 00:49:46,719 Speaker 1: these will tell me why these were pretty terrifying creatures. 868 00:49:47,000 --> 00:49:51,680 Speaker 1: So late Cretaceous is the time period the location asia 869 00:49:52,000 --> 00:49:56,240 Speaker 1: modern day Mongolian parts of China. These guys were six 870 00:49:56,239 --> 00:49:59,680 Speaker 1: ft long or one point eight meters long, so there 871 00:49:59,680 --> 00:50:03,840 Speaker 1: an growth the family Dromeo Saraday and they look pretty 872 00:50:03,920 --> 00:50:06,160 Speaker 1: much like the creatures you know and love from the 873 00:50:06,239 --> 00:50:11,560 Speaker 1: Jurassic Park movies, but with three major differing factors here. 874 00:50:12,160 --> 00:50:15,120 Speaker 1: So first of all, we know now that they had feathers, 875 00:50:15,360 --> 00:50:19,600 Speaker 1: likely iridescent feathers, Okay, So I don't think that takes 876 00:50:19,600 --> 00:50:22,640 Speaker 1: away from the terrifying nature of the velociraptor. I know 877 00:50:22,680 --> 00:50:24,400 Speaker 1: a lot of people don't like it. I love it. 878 00:50:24,440 --> 00:50:27,799 Speaker 1: I think that's even better. But birds are scarier than lizards. Yeah, 879 00:50:27,840 --> 00:50:29,440 Speaker 1: birds are scary. And you know what, you don't have 880 00:50:29,520 --> 00:50:32,960 Speaker 1: to like it. That's what the science says. Uh. They 881 00:50:33,000 --> 00:50:35,480 Speaker 1: had feathers and they were terrifying. You don't have to 882 00:50:35,520 --> 00:50:38,040 Speaker 1: like it to be eaten. They don't care. The velociraptor 883 00:50:38,120 --> 00:50:40,640 Speaker 1: doesn't care if you're if you approve, if it's uh, 884 00:50:40,680 --> 00:50:44,400 Speaker 1: if it's plumage. And second, the head is all wrong 885 00:50:44,440 --> 00:50:49,000 Speaker 1: in the movies. Okay, so the actual velociraptor probably had 886 00:50:49,040 --> 00:50:51,840 Speaker 1: a head that was you know, it is a long, low, 887 00:50:52,000 --> 00:50:55,799 Speaker 1: flat snouted head. It looked more like an alligator. And 888 00:50:55,920 --> 00:50:58,840 Speaker 1: a third it was it was This was a smaller 889 00:50:58,880 --> 00:51:00,480 Speaker 1: creature than you see in them, of vise. It was 890 00:51:00,480 --> 00:51:04,719 Speaker 1: about the size of a large dog, not as tall. Yeah, yeah, 891 00:51:04,719 --> 00:51:07,560 Speaker 1: a bit longer. So the creature you see in Jurassic 892 00:51:07,680 --> 00:51:13,000 Speaker 1: Park is actually patterned after Udnonicus, which is a close 893 00:51:13,120 --> 00:51:17,240 Speaker 1: relative in the same family. So Michael Crichton basically wrote 894 00:51:17,280 --> 00:51:22,919 Speaker 1: about Dnonicus, but thought, hey, velass velociraptor sounds cooler. We'll 895 00:51:22,960 --> 00:51:25,239 Speaker 1: just make it be Adnonicus and then we'll call it 896 00:51:25,320 --> 00:51:27,279 Speaker 1: of a loci raptor. Now I don't know if this 897 00:51:27,360 --> 00:51:31,480 Speaker 1: theory is correct, but I have read that people essentially 898 00:51:31,520 --> 00:51:36,040 Speaker 1: figured out why Crichton chose the name of velociraptor, and 899 00:51:36,080 --> 00:51:38,920 Speaker 1: it's that they think he was using as a major 900 00:51:39,120 --> 00:51:43,959 Speaker 1: research resource for Jurassic Park, this one particular book by 901 00:51:44,080 --> 00:51:48,279 Speaker 1: this author who had an idiosyncratic view of Dinonicus and 902 00:51:48,440 --> 00:51:52,120 Speaker 1: thought that it was a velociraptor of a different type. 903 00:51:52,760 --> 00:51:54,920 Speaker 1: So I have read that. I don't know if that's correct, 904 00:51:54,960 --> 00:51:57,000 Speaker 1: and I guess I guess Michael Crichton has passed on 905 00:51:57,080 --> 00:51:59,600 Speaker 1: and we can't ask him, but but I have heard 906 00:51:59,680 --> 00:52:02,960 Speaker 1: that's jested as how that mix up happened. Okay, so 907 00:52:03,000 --> 00:52:05,160 Speaker 1: he might have had a little more excuse there as 908 00:52:05,160 --> 00:52:08,440 Speaker 1: opposed to just it sounds cooler. But regardless, we know 909 00:52:08,560 --> 00:52:11,840 Speaker 1: better now, and we're still depicting these Jurassic Park movies. 910 00:52:11,920 --> 00:52:14,200 Speaker 1: They're still making more, aren't they. Yeah, they're still making more, 911 00:52:14,200 --> 00:52:18,520 Speaker 1: and they're still depicting the velociraptor as Adnonicus without feathers, 912 00:52:19,400 --> 00:52:23,799 Speaker 1: which I think they have a responsibility to to fix that. 913 00:52:23,840 --> 00:52:27,560 Speaker 1: I mean, granted, nobody's going in and watching Jurassic Park 914 00:52:27,640 --> 00:52:29,440 Speaker 1: or Jurassic World or whatever. The next one is going 915 00:52:29,480 --> 00:52:33,719 Speaker 1: to be called as their hopefully as their primary educational 916 00:52:34,640 --> 00:52:39,239 Speaker 1: dinosaur documentary. Hopefully that's not also where you get your 917 00:52:39,239 --> 00:52:42,719 Speaker 1: info about chaos theory, right. But but on the other hand, 918 00:52:42,880 --> 00:52:47,400 Speaker 1: like this is still like a prime visualization of dinosaur life. 919 00:52:47,440 --> 00:52:49,479 Speaker 1: I mean, it's it's a it's amazing footage. They're putting 920 00:52:49,480 --> 00:52:51,640 Speaker 1: all this money into it. Why not make it match 921 00:52:51,719 --> 00:52:55,520 Speaker 1: up with our current understanding of the fossil record. I 922 00:52:55,600 --> 00:52:58,680 Speaker 1: why not have some some feathered dnonicus or just go ahead, 923 00:52:58,719 --> 00:53:01,440 Speaker 1: have feathered velociraptors. Because the thing is, even though they 924 00:53:01,440 --> 00:53:03,719 Speaker 1: were smaller than what you see in the movie, they 925 00:53:03,800 --> 00:53:06,000 Speaker 1: still would have been deadly, especially if they were hunting 926 00:53:06,000 --> 00:53:08,320 Speaker 1: in a pack. Yeah. Yeah, I mean think how scary 927 00:53:08,360 --> 00:53:11,439 Speaker 1: that would be to get get attacked by these tiny things? Yeah, 928 00:53:11,520 --> 00:53:13,319 Speaker 1: or you know, dog size thing. Nobody wants to get 929 00:53:13,320 --> 00:53:15,160 Speaker 1: eaten by a pack of dogs as tiny as a 930 00:53:15,239 --> 00:53:17,560 Speaker 1: relative word or a tiny relative to what they were. 931 00:53:18,480 --> 00:53:21,440 Speaker 1: And it's certainly in the dinosaurs seen a scheme of things. 932 00:53:22,040 --> 00:53:25,120 Speaker 1: So no matter how you shake it, the raptor was 933 00:53:25,200 --> 00:53:29,399 Speaker 1: indeed a member of the terrible cloud lizards group here, 934 00:53:29,600 --> 00:53:33,880 Speaker 1: all of which were swift, fearsome hunters, probably pack hunters 935 00:53:33,880 --> 00:53:37,440 Speaker 1: in many cases. Uh, there's controversy about that we can 936 00:53:37,440 --> 00:53:40,040 Speaker 1: get into it, get back to especially concerning Denona, because 937 00:53:40,280 --> 00:53:44,560 Speaker 1: they would have had large brains, elongated sickle shaped claws 938 00:53:44,560 --> 00:53:47,200 Speaker 1: on the second toe of each foot, and uh as 939 00:53:47,239 --> 00:53:50,360 Speaker 1: the as Jurassic Park indicates. They would have been clever girls. 940 00:53:51,320 --> 00:53:53,960 Speaker 1: But they were probably not as smart as cats or 941 00:53:54,000 --> 00:53:56,480 Speaker 1: dogs are today, so don't get too excited about that. 942 00:53:56,680 --> 00:54:00,400 Speaker 1: They couldn't have, you know, piloted a helicopter, so you 943 00:54:00,440 --> 00:54:03,359 Speaker 1: think maybe smart for dinosaurs, but not as smart as 944 00:54:03,360 --> 00:54:09,320 Speaker 1: the movies would have you believe. Probably mean that's probably 945 00:54:09,360 --> 00:54:12,040 Speaker 1: a larger conversation, right, because I've seen my car to 946 00:54:12,080 --> 00:54:15,520 Speaker 1: try to open a door, So who's to say that 947 00:54:15,600 --> 00:54:18,600 Speaker 1: a dinosaur couldn't open a door. We'll leave that one 948 00:54:18,640 --> 00:54:21,560 Speaker 1: for another another episode. But will your cat run with 949 00:54:21,600 --> 00:54:25,239 Speaker 1: your motorcycle gang? Oh well no, probably not. I think 950 00:54:25,280 --> 00:54:27,560 Speaker 1: she would. She would flatly refuse to do that. Okay, 951 00:54:27,560 --> 00:54:30,080 Speaker 1: we'll leave Jurassic World out of this now. Now tell 952 00:54:30,160 --> 00:54:32,200 Speaker 1: us about the other contender here, Robert, all right, the 953 00:54:32,200 --> 00:54:36,840 Speaker 1: other contender is Protoceratops. This one you've seen many pictures 954 00:54:36,840 --> 00:54:39,680 Speaker 1: of this one before. It was a common dinosaur, and 955 00:54:39,719 --> 00:54:44,480 Speaker 1: it's essentially a smaller tri Serratops. Smaller horned dinosaur, but 956 00:54:44,800 --> 00:54:47,959 Speaker 1: without any of the without any of the horns, say 957 00:54:48,040 --> 00:54:50,879 Speaker 1: for a sort of nose bulge. Okay, now it does 958 00:54:50,920 --> 00:54:53,600 Speaker 1: have like a frill, right, yes, it does have a 959 00:54:53,719 --> 00:54:56,880 Speaker 1: broad neck frill. And this was primarily to to anchor 960 00:54:57,000 --> 00:55:01,359 Speaker 1: muscles for the heavy toothed beak and aw, so it 961 00:55:01,400 --> 00:55:03,160 Speaker 1: was and it and its one horn was more of 962 00:55:03,200 --> 00:55:05,600 Speaker 1: a crest, and this crest was larger and older males, 963 00:55:05,640 --> 00:55:08,760 Speaker 1: suggesting it was probably used in mating battles. It walked 964 00:55:08,800 --> 00:55:10,680 Speaker 1: on all fours, though it may have been able to 965 00:55:10,800 --> 00:55:14,759 Speaker 1: run on its back legs when needed. So this is 966 00:55:14,800 --> 00:55:20,200 Speaker 1: where we get a really important dinosaur combat fossil, also 967 00:55:20,320 --> 00:55:25,040 Speaker 1: known as the fighting dinosaurs. Uh and this was This 968 00:55:25,080 --> 00:55:29,279 Speaker 1: was a nine find in Mongolia, and it seems to 969 00:55:29,280 --> 00:55:33,080 Speaker 1: show a deadly battle between a velociraptor and a protoceratops 970 00:55:33,160 --> 00:55:36,839 Speaker 1: roughly seventy four million years old. One interpretation is that 971 00:55:36,880 --> 00:55:40,000 Speaker 1: the raptor is eviscerating its prey with its claws, while 972 00:55:40,040 --> 00:55:43,000 Speaker 1: the protoceratops is caving in the predator's chest with its 973 00:55:43,000 --> 00:55:46,600 Speaker 1: horned beak. Another interpretation is that the raptor is slicing 974 00:55:46,600 --> 00:55:50,319 Speaker 1: open the throat and the Protoceratops is biting down on 975 00:55:50,440 --> 00:55:53,600 Speaker 1: the raptor's right arm with its beak. Either way, it's 976 00:55:53,640 --> 00:55:57,440 Speaker 1: a deadly tableau that indicates they died at the same time. 977 00:55:58,160 --> 00:56:01,839 Speaker 1: UM A Polish Mongolian team discovered it in the White 978 00:56:01,880 --> 00:56:05,439 Speaker 1: stand Zone cliffs of the Southern Gobi Desert and it's 979 00:56:05,560 --> 00:56:08,880 Speaker 1: considered a national treasure of Mongolia and you can you 980 00:56:08,920 --> 00:56:11,799 Speaker 1: can see it on display in the Mongolian Dinosaur Museum 981 00:56:11,840 --> 00:56:15,480 Speaker 1: in ulm Pitar. I've never heard of that museum before, 982 00:56:15,520 --> 00:56:18,359 Speaker 1: but Mongolia is a treasure trove of fossils. I bet 983 00:56:18,400 --> 00:56:20,840 Speaker 1: that place is awesome. Yeah. I tried to go to 984 00:56:20,880 --> 00:56:23,440 Speaker 1: the website but it was down. I would certainly love 985 00:56:23,520 --> 00:56:27,960 Speaker 1: to hear from anyone who's actually been there. So interpretations 986 00:56:28,120 --> 00:56:30,800 Speaker 1: vary on this encounter, Like you know, certainly it's an encounter. 987 00:56:31,040 --> 00:56:33,640 Speaker 1: Nobody seems to be doubting that, but some look to 988 00:56:33,800 --> 00:56:37,160 Speaker 1: it as a preserved example of a common encounter like these. 989 00:56:37,360 --> 00:56:39,520 Speaker 1: This was the common predator and this was the common prey, 990 00:56:39,760 --> 00:56:41,520 Speaker 1: and this kind of thing went down all the time 991 00:56:41,920 --> 00:56:43,799 Speaker 1: in the past. Others have argued that it might have 992 00:56:43,800 --> 00:56:46,239 Speaker 1: been a chance encounter between two species that didn't have 993 00:56:46,320 --> 00:56:49,920 Speaker 1: much to do with each other. Um this, and this 994 00:56:50,080 --> 00:56:53,040 Speaker 1: illustrates some of the problems with basing everything you know 995 00:56:53,800 --> 00:56:59,480 Speaker 1: about prehistoric species interaction on a single bit of evidence totally. 996 00:57:00,200 --> 00:57:03,000 Speaker 1: But that's not all. Luckily so, a two thousand ten 997 00:57:03,120 --> 00:57:09,400 Speaker 1: study published in the journal paleo Geography, Paleoclimatology, Paleoecology revealed 998 00:57:10,040 --> 00:57:13,919 Speaker 1: some corroborating fossil evidence uh so that we're talking about 999 00:57:13,960 --> 00:57:18,960 Speaker 1: Upper Cretaceous deposits uh in inner Mongolia UH that features 1000 00:57:19,080 --> 00:57:23,640 Speaker 1: a mass of badly eroded Protoceratops bones. Among them, they 1001 00:57:23,640 --> 00:57:27,560 Speaker 1: found two velociraptor like teeth and bite marks, So the 1002 00:57:27,760 --> 00:57:31,960 Speaker 1: paleontologists stressed that this uh, this raptor in this case 1003 00:57:32,160 --> 00:57:36,400 Speaker 1: likely scavenged its meal. But this find and the fighting 1004 00:57:36,440 --> 00:57:41,000 Speaker 1: dinosaurs of find indicate that the creatures probably regularly fed 1005 00:57:41,040 --> 00:57:45,360 Speaker 1: on Protoceratops, both as hunters and scavengers. And they point 1006 00:57:45,400 --> 00:57:48,880 Speaker 1: out that almost all living carnivores do the exact same 1007 00:57:48,920 --> 00:57:53,600 Speaker 1: thing with their core prey species. You would rather just 1008 00:57:53,720 --> 00:57:56,520 Speaker 1: come across a dead one and eat that without having 1009 00:57:56,560 --> 00:58:01,240 Speaker 1: to struggle, But if you're starving, you'll yeah, or or 1010 00:58:01,320 --> 00:58:04,840 Speaker 1: likewise that maybe you know, maybe you prefer the thrill 1011 00:58:04,920 --> 00:58:07,880 Speaker 1: of the kill that the fresh meat. Though of course, 1012 00:58:07,920 --> 00:58:09,720 Speaker 1: any interaction like that is going to bring the risk 1013 00:58:09,760 --> 00:58:13,080 Speaker 1: of injury or death. Uh, and injury for a predator 1014 00:58:13,160 --> 00:58:18,280 Speaker 1: can be a major thing. Like I remember researching these 1015 00:58:18,520 --> 00:58:22,000 Speaker 1: these cases where male cheetahs develop a strategy for bringing 1016 00:58:22,000 --> 00:58:26,240 Speaker 1: down an ostrich, which generally isn't on the menu. And 1017 00:58:26,280 --> 00:58:28,960 Speaker 1: one of the reasons is taking down an ostrich is dangerous. 1018 00:58:29,400 --> 00:58:31,560 Speaker 1: And if you're a cheetah that depends on high speed, 1019 00:58:32,000 --> 00:58:34,640 Speaker 1: an injury can mean starvation because it's not like you 1020 00:58:34,640 --> 00:58:36,520 Speaker 1: can just go on the shelf and recoup and then 1021 00:58:36,560 --> 00:58:38,200 Speaker 1: get back in the game. Now that that could be 1022 00:58:38,240 --> 00:58:43,560 Speaker 1: a death sentence. Um, So yeah, taking on dangerous prey 1023 00:58:43,800 --> 00:58:47,120 Speaker 1: is dangerous. Well, that is a perfect segue into our 1024 00:58:47,160 --> 00:58:53,560 Speaker 1: next conflict, which is the showdown between Tanantasaurus and Dynonicus. 1025 00:58:54,240 --> 00:58:56,280 Speaker 1: So now we're gonna be looking at what are assumed 1026 00:58:56,320 --> 00:59:00,320 Speaker 1: to be a standard predator and prey species of North America. 1027 00:59:00,520 --> 00:59:05,840 Speaker 1: So Tanantasaurus, which is uh that means sinew lizard lived 1028 00:59:05,840 --> 00:59:08,000 Speaker 1: in the early Cretaceous a little more than a hundred 1029 00:59:08,000 --> 00:59:12,120 Speaker 1: million years ago in North America, especially western regions, and 1030 00:59:12,200 --> 00:59:14,640 Speaker 1: it's about six to eight meters long, up to around 1031 00:59:14,720 --> 00:59:19,320 Speaker 1: two ms high, about two thousand to hundred pounds, and 1032 00:59:19,360 --> 00:59:23,280 Speaker 1: then we're back to Denonicus. Uh. That's the genus that 1033 00:59:23,480 --> 00:59:27,840 Speaker 1: includes the species Denonicus and tirapists. That's also Early Cretaceous, 1034 00:59:27,880 --> 00:59:31,320 Speaker 1: same same time period, pretty much a hundred million years ago, 1035 00:59:31,440 --> 00:59:36,000 Speaker 1: roughly uh, North America, United States, and Denonicus is up 1036 00:59:36,040 --> 00:59:38,040 Speaker 1: to about three and a half ms long, maybe a 1037 00:59:38,080 --> 00:59:40,600 Speaker 1: little more than a meter high, usually about a hundred 1038 00:59:40,640 --> 00:59:44,120 Speaker 1: and fifty pounds, so also not huge. You know, we 1039 00:59:44,120 --> 00:59:48,120 Speaker 1: were just talking about the smallness of the raptor um. 1040 00:59:48,280 --> 00:59:52,080 Speaker 1: There is a great story about this fossil tableau I'm 1041 00:59:52,080 --> 00:59:54,720 Speaker 1: about I'm about to explain. But the story is by 1042 00:59:55,120 --> 00:59:59,160 Speaker 1: Desmond Maxwell and the December nine to January two thousand 1043 00:59:59,200 --> 01:00:01,800 Speaker 1: issue of Natural History magazine, which I think that's the 1044 01:00:01,840 --> 01:00:04,160 Speaker 1: magazine put out by the American Museum and Natural History, 1045 01:00:04,200 --> 01:00:07,680 Speaker 1: I think UM. And it's describing the work of the 1046 01:00:07,800 --> 01:00:13,920 Speaker 1: Yale Peabody Museum paleontologist John Ostrom and others in understanding 1047 01:00:14,000 --> 01:00:20,000 Speaker 1: Dononicus largely through its relationship with its supposed prey to Nontosaurus. 1048 01:00:20,000 --> 01:00:22,560 Speaker 1: So John Ostrom is now known as this really important 1049 01:00:22,680 --> 01:00:27,200 Speaker 1: very influential twentieth century paleontologist, and he's widely associated with 1050 01:00:27,240 --> 01:00:31,880 Speaker 1: our current understanding of dinosaurs as the ancestors of modern birds. 1051 01:00:32,520 --> 01:00:35,400 Speaker 1: People had gone back and forth in the paleontology community 1052 01:00:35,440 --> 01:00:38,720 Speaker 1: about the relationship between dinosaurs and birds. I think during 1053 01:00:38,760 --> 01:00:42,600 Speaker 1: the eighteen hundreds people associated dinosaurs with birds, but then 1054 01:00:42,640 --> 01:00:46,000 Speaker 1: a lizard model seemed to take over, and then the 1055 01:00:46,040 --> 01:00:50,640 Speaker 1: bird model started coming back. So in the mid nineteen sixties, 1056 01:00:50,960 --> 01:00:55,640 Speaker 1: Ostrom was working on fossil fossil excavations in the Cloverlely 1057 01:00:55,840 --> 01:00:59,760 Speaker 1: Formation in Montana and Wyoming. I think this was southern Montana, 1058 01:01:00,480 --> 01:01:02,680 Speaker 1: and on the last day of the digging season in 1059 01:01:02,800 --> 01:01:07,680 Speaker 1: nineteen sixty four, Ostrom discovered a composed scene of fossil 1060 01:01:07,720 --> 01:01:10,880 Speaker 1: bones that was totally unlike anything he had encountered in 1061 01:01:10,920 --> 01:01:14,720 Speaker 1: his work before, where there were five specimens in total 1062 01:01:14,800 --> 01:01:18,680 Speaker 1: at this site. Four were small therapods. Now, when you 1063 01:01:18,680 --> 01:01:23,520 Speaker 1: think therapod, that's sort of the velociraptor or tyrannosaurus kind 1064 01:01:23,520 --> 01:01:26,320 Speaker 1: of model, you know, two legs, the that that kind 1065 01:01:26,360 --> 01:01:30,600 Speaker 1: of thing, and then pieces of one large ornithopod. Her 1066 01:01:30,680 --> 01:01:34,440 Speaker 1: before in the site where these were discovered came to 1067 01:01:34,440 --> 01:01:39,280 Speaker 1: be known by the Yale excavation crew as the shrine site. Yeah, 1068 01:01:39,360 --> 01:01:42,800 Speaker 1: it evokes this kind of holy mystery. Neither of these 1069 01:01:42,800 --> 01:01:45,680 Speaker 1: species had been described in the scientific literature before, though 1070 01:01:45,720 --> 01:01:48,440 Speaker 1: I think denonicas skeletons had been found, They hadn't just 1071 01:01:48,520 --> 01:01:52,320 Speaker 1: they just hadn't really been described by scientists. And the 1072 01:01:52,360 --> 01:01:56,600 Speaker 1: small therapods were most noticeable for this one huge hook 1073 01:01:56,680 --> 01:02:00,360 Speaker 1: shaped claw found on each foot, and this in them 1074 01:02:00,360 --> 01:02:05,160 Speaker 1: their name Denonicus, also of course means terrible claw. Meanwhile, 1075 01:02:05,240 --> 01:02:10,280 Speaker 1: this one large herbivore was called Tanantosaurus, meaning sinew lizard. 1076 01:02:11,840 --> 01:02:16,880 Speaker 1: It's kind of they should have called it like gristle lizard. Now, 1077 01:02:16,920 --> 01:02:20,840 Speaker 1: because of the arrangement of the fossils, Ostrom came to 1078 01:02:20,840 --> 01:02:26,040 Speaker 1: a strange conclusion. These four predator carcasses lie, you know, 1079 01:02:26,080 --> 01:02:29,520 Speaker 1: they lay buried around the remains of one large prey animal, 1080 01:02:29,840 --> 01:02:32,440 Speaker 1: and because of the nature of the area. Looking at 1081 01:02:32,840 --> 01:02:36,400 Speaker 1: how the bodies were oriented and some stuff about the sediment, 1082 01:02:36,760 --> 01:02:39,680 Speaker 1: Ostrom didn't think the bones could have been washed into 1083 01:02:39,720 --> 01:02:42,680 Speaker 1: the plate into that place by moving water. The fossils 1084 01:02:42,720 --> 01:02:45,800 Speaker 1: appeared to be lying in the place where the animals died, 1085 01:02:46,280 --> 01:02:50,960 Speaker 1: so he concluded that Denonicus was a pack hunter. Now 1086 01:02:50,960 --> 01:02:54,440 Speaker 1: you remember this from Jurassic Park, right, their pack hunters, 1087 01:02:54,520 --> 01:02:57,040 Speaker 1: you know all that. So the scene, as you should 1088 01:02:57,080 --> 01:02:59,920 Speaker 1: imagine it, is that a pack of around eight denonic 1089 01:03:00,000 --> 01:03:05,080 Speaker 1: becus attacked, wore down, and killed this much larger prey animal, 1090 01:03:05,200 --> 01:03:08,560 Speaker 1: the Tanantosaurus, but not before about half of the hunting 1091 01:03:08,560 --> 01:03:12,480 Speaker 1: pack was injured and killed in the struggle. And now 1092 01:03:12,520 --> 01:03:15,960 Speaker 1: this interpretation has remained very controversial. Scientists go back and 1093 01:03:16,000 --> 01:03:18,880 Speaker 1: forth on it. In Jurassic Park, we do see the 1094 01:03:18,920 --> 01:03:23,520 Speaker 1: stand in for the Denonicus executing these complex pack hunting behaviors, 1095 01:03:23,520 --> 01:03:26,640 Speaker 1: but real evidence for this kind of pack hunting behavior 1096 01:03:26,720 --> 01:03:30,600 Speaker 1: has been kind of elusive. And the article basically mentions 1097 01:03:30,720 --> 01:03:34,160 Speaker 1: three main lines of evidence that the Didonicus were pack hunters. 1098 01:03:34,680 --> 01:03:37,680 Speaker 1: One of them is the arrangement of bones itself, the 1099 01:03:37,720 --> 01:03:41,080 Speaker 1: weird way the bones are laid out at the shrine. Now, 1100 01:03:41,200 --> 01:03:44,160 Speaker 1: it's fairly certain that the fossilized animals died in the 1101 01:03:44,240 --> 01:03:46,680 Speaker 1: position where they were found. And here's one good piece 1102 01:03:46,680 --> 01:03:51,520 Speaker 1: of evidence. After a dinosaur dies, tendons in the vertebrae 1103 01:03:51,600 --> 01:03:54,720 Speaker 1: cause a curling up of the neck and the tail 1104 01:03:55,040 --> 01:03:58,480 Speaker 1: spine along the backbone essentially, and this is why you 1105 01:03:58,560 --> 01:04:01,920 Speaker 1: sometimes see dinosaur falls with their necks curled back in 1106 01:04:01,960 --> 01:04:05,880 Speaker 1: these crazy positions, as if screaming in pain. You know 1107 01:04:05,920 --> 01:04:09,480 Speaker 1: what I'm talking about. Uh. This is generally thought to 1108 01:04:09,520 --> 01:04:14,560 Speaker 1: be called caused by this contraction of the vertebral tendons 1109 01:04:14,600 --> 01:04:18,520 Speaker 1: as the animal rots. Now, in the specimen the Tenantosaurus, 1110 01:04:18,600 --> 01:04:21,120 Speaker 1: the tail and neck were heavily curved towards each other, 1111 01:04:21,480 --> 01:04:24,360 Speaker 1: making it almost impossible that the body had been moved 1112 01:04:24,360 --> 01:04:27,520 Speaker 1: around by water currents. It looked like this is where 1113 01:04:27,520 --> 01:04:31,600 Speaker 1: it was when it died. So if multiple Denonicus died 1114 01:04:31,640 --> 01:04:36,160 Speaker 1: alongside this one large Tenantosaurus at the same time and 1115 01:04:36,200 --> 01:04:39,880 Speaker 1: in the same place, what would explain that other than 1116 01:04:39,960 --> 01:04:43,880 Speaker 1: some deadly fight for survival? Uh? So, the Tenantosaurus is 1117 01:04:43,920 --> 01:04:47,720 Speaker 1: certainly large enough to batter, crush, and kill the relatively 1118 01:04:47,760 --> 01:04:52,120 Speaker 1: small predators. Right that it wouldn't be one Dnonicus versus 1119 01:04:52,160 --> 01:04:54,520 Speaker 1: a Tenanto sourus wouldn't be much of a fight. The 1120 01:04:54,560 --> 01:04:58,320 Speaker 1: prey animal is much bigger. Uh. Then again, if a 1121 01:04:58,400 --> 01:05:01,680 Speaker 1: pack of eight attacked the this one prey animal and 1122 01:05:01,720 --> 01:05:04,360 Speaker 1: half of the pack died, that does not sound like 1123 01:05:04,400 --> 01:05:08,240 Speaker 1: a sustainable hunting strategy. That is that that that is 1124 01:05:08,280 --> 01:05:11,160 Speaker 1: that does not pay off for the hunters here, right, 1125 01:05:11,200 --> 01:05:14,320 Speaker 1: So was it a fluke? Are we seeing some incredibly weird, 1126 01:05:14,600 --> 01:05:19,720 Speaker 1: rare event where the predators desperate and starving? There's an 1127 01:05:19,720 --> 01:05:22,919 Speaker 1: alternate explanation of the site, which is that the denonicus 1128 01:05:23,320 --> 01:05:27,160 Speaker 1: were scavenging. The ideas that a bunch of dnonicus came 1129 01:05:27,200 --> 01:05:30,160 Speaker 1: across the corpse of a dead tenanta sore and somehow 1130 01:05:30,320 --> 01:05:33,400 Speaker 1: died in the feeding process of scavenging on it. But 1131 01:05:33,480 --> 01:05:36,600 Speaker 1: then you're faced with another odd question, what killed him? Like? 1132 01:05:36,720 --> 01:05:40,080 Speaker 1: Why did all these different denonicus die while scavenging this 1133 01:05:40,120 --> 01:05:44,680 Speaker 1: one corpse? The scavenging interpretation that has been advocated by 1134 01:05:44,680 --> 01:05:47,880 Speaker 1: the prominent paleontologist Jack Horner, And I want to read 1135 01:05:47,920 --> 01:05:50,360 Speaker 1: a quote from the article I described It said, quote 1136 01:05:50,640 --> 01:05:55,200 Speaker 1: Horner likens the idea of a Tenantasaurus killing four dinonicus 1137 01:05:55,200 --> 01:06:00,320 Speaker 1: to that of a lone willed to best dispatching four lions. True, 1138 01:06:00,320 --> 01:06:02,200 Speaker 1: the will to beast is bigger than the lions, right, 1139 01:06:02,240 --> 01:06:04,280 Speaker 1: but it just seems kind of crazy thinking it would 1140 01:06:04,320 --> 01:06:08,000 Speaker 1: like kill all these predators. But back to the quote, Yet, 1141 01:06:08,440 --> 01:06:10,960 Speaker 1: an adult will to beast might weigh from fifty to 1142 01:06:11,040 --> 01:06:14,240 Speaker 1: a hundred pounds more than an adult lion, compared with 1143 01:06:14,280 --> 01:06:17,760 Speaker 1: the difference of about a ton between the Tenantosaurus and 1144 01:06:17,800 --> 01:06:20,960 Speaker 1: the Dynonicus preserved at the shrine site. A will to 1145 01:06:21,000 --> 01:06:24,040 Speaker 1: beast falling on a lion would probably inflict little damage. 1146 01:06:24,240 --> 01:06:29,800 Speaker 1: A Tenantosurus would crush at anonicus, So some evidence going 1147 01:06:29,840 --> 01:06:31,680 Speaker 1: both ways there. It's hard to know what to think, 1148 01:06:32,080 --> 01:06:34,600 Speaker 1: but a couple other interesting lines of thought. One of 1149 01:06:34,640 --> 01:06:38,760 Speaker 1: them is teeth. Now, the Tanata source remains are associated 1150 01:06:38,800 --> 01:06:41,200 Speaker 1: with lots of Denonicus teeth. It seems like when you 1151 01:06:41,240 --> 01:06:45,120 Speaker 1: find one of these prey animals dead, there's Denonicus teeth 1152 01:06:45,160 --> 01:06:50,080 Speaker 1: all around. That tells you something, right, It indicates a 1153 01:06:50,080 --> 01:06:54,600 Speaker 1: predator prey relationship um there. And there's so many Denonicus 1154 01:06:54,680 --> 01:06:58,240 Speaker 1: teeth found with Tenantosurus remains, way more than you could 1155 01:06:58,280 --> 01:07:01,520 Speaker 1: reasonably expect to be lost to a like by a 1156 01:07:01,640 --> 01:07:07,240 Speaker 1: soliditary scavenger. If one came across one Dnonicus was eating 1157 01:07:07,280 --> 01:07:10,400 Speaker 1: off of a dead corpse, it wouldn't leave eleven teeth 1158 01:07:10,440 --> 01:07:13,000 Speaker 1: in it, right, That's just too many teeth to be 1159 01:07:13,080 --> 01:07:17,800 Speaker 1: lost to be sustainable. Also, the placement of the teeth 1160 01:07:18,120 --> 01:07:21,960 Speaker 1: tends to concentrate in the abdomen and pelvis. Why is 1161 01:07:22,000 --> 01:07:25,640 Speaker 1: that interesting, Well, it's actually consistent with what you see 1162 01:07:25,640 --> 01:07:30,080 Speaker 1: in predators today, where predators tend to feed on these areas, 1163 01:07:30,160 --> 01:07:33,240 Speaker 1: the abdomen and the pelvis first. When they kill an 1164 01:07:33,240 --> 01:07:35,800 Speaker 1: animal freshly, Uh, they tend to go for the parts 1165 01:07:35,800 --> 01:07:38,160 Speaker 1: while they're still sort of warm and moist, to be 1166 01:07:38,200 --> 01:07:41,640 Speaker 1: a little gross, to be a little wallace as children's 1167 01:07:41,720 --> 01:07:45,480 Speaker 1: children's book material, folks. So if the dnonicus were doing 1168 01:07:45,520 --> 01:07:47,680 Speaker 1: the same, it looks like they were feeding on a 1169 01:07:47,720 --> 01:07:51,480 Speaker 1: fresh kill, not scavenging piecemeal on some dead animal that 1170 01:07:51,600 --> 01:07:55,320 Speaker 1: came across. And then one final point, the anatomy of 1171 01:07:55,320 --> 01:07:58,320 Speaker 1: the dnonicus makes it look plausibly like a pack hunter. 1172 01:07:58,720 --> 01:08:01,280 Speaker 1: It's got this one terrible law that looks effective for 1173 01:08:01,360 --> 01:08:05,880 Speaker 1: both grasping and slashing. Uh. The the an tirapists part 1174 01:08:05,920 --> 01:08:10,040 Speaker 1: of the name the dnonicus and tirapists that means counterbalancing, 1175 01:08:10,400 --> 01:08:14,080 Speaker 1: referring to the bone structure of the tail. Now why 1176 01:08:14,080 --> 01:08:17,040 Speaker 1: would that matter, Well, it means that the animal is 1177 01:08:17,080 --> 01:08:21,519 Speaker 1: capable of making its tail rigid and using it as 1178 01:08:21,560 --> 01:08:25,280 Speaker 1: a counterweight to balance and control the movement of its body, 1179 01:08:25,680 --> 01:08:31,200 Speaker 1: which suggests kind of quick graceful movement and the lightweight 1180 01:08:31,280 --> 01:08:33,799 Speaker 1: of the predator's body also kind of suggests a fast, 1181 01:08:33,880 --> 01:08:38,160 Speaker 1: active hunter rather than a passive scavenger. So we still 1182 01:08:38,160 --> 01:08:41,440 Speaker 1: don't know whether the pack hunting interpretation of the Dononicus 1183 01:08:41,560 --> 01:08:45,080 Speaker 1: is correct, but some subsequent studies kind of try to 1184 01:08:45,200 --> 01:08:47,920 Speaker 1: endorse the idea. Others have some evidence against it. We 1185 01:08:47,960 --> 01:08:51,000 Speaker 1: don't know for sure, but this one site, with all 1186 01:08:51,040 --> 01:08:54,920 Speaker 1: these with these dead predators and dead prey together is 1187 01:08:54,920 --> 01:08:57,360 Speaker 1: still something that's really interesting to think about and how 1188 01:08:57,400 --> 01:09:01,439 Speaker 1: it informs our understanding of how these almost hunted. All Right, 1189 01:09:01,640 --> 01:09:04,240 Speaker 1: it's main event time. And when it comes to main 1190 01:09:04,320 --> 01:09:07,479 Speaker 1: event to combat between dinosaurs, you know, what's what's the 1191 01:09:07,600 --> 01:09:11,480 Speaker 1: kirk Khan, What's the Flair steamboat, the Massawa Coba Kobashi, 1192 01:09:11,800 --> 01:09:15,960 Speaker 1: the batman joke, or the gandolf ball rog encounter. What's 1193 01:09:16,000 --> 01:09:19,519 Speaker 1: the one that that is so prominently featured in so 1194 01:09:19,560 --> 01:09:23,160 Speaker 1: many dinosaur books for children, for adults, even like a 1195 01:09:23,240 --> 01:09:28,639 Speaker 1: paleontology textbooks. What is the what is the iconic battle? Well, 1196 01:09:28,640 --> 01:09:31,280 Speaker 1: it has to be everybody's favorite herbivore, which would be 1197 01:09:31,320 --> 01:09:34,880 Speaker 1: what tri saratops and everybody's favorite carnivore, which would be 1198 01:09:35,000 --> 01:09:37,720 Speaker 1: turning the source Rex. That's correct. Now, I will say 1199 01:09:37,720 --> 01:09:43,240 Speaker 1: Stegasaurus is also a pretty awesome herbivore. People love those thagomizers. Yeah, 1200 01:09:43,280 --> 01:09:47,479 Speaker 1: the thagomizers named for Gary Larson cartoon. These are, of 1201 01:09:47,479 --> 01:09:51,040 Speaker 1: course the spikes and the tail of the Stegasaurus. Uh. Sadly, 1202 01:09:51,040 --> 01:09:54,599 Speaker 1: Stegasaurus will have to wait for another episode to get 1203 01:09:54,600 --> 01:09:58,160 Speaker 1: his due. But in this case, yes, t Rex versus 1204 01:09:58,160 --> 01:10:02,880 Speaker 1: tri Sarah tops the cl pasic the paleo artists the 1205 01:10:03,000 --> 01:10:05,560 Speaker 1: favorite battle. So let's go into a rundown of the 1206 01:10:05,800 --> 01:10:09,760 Speaker 1: two combinants. Here we have Tarannosaurus rex t rex late 1207 01:10:09,760 --> 01:10:14,559 Speaker 1: Cretaceous North America and Asia as It's stomping grounds size 1208 01:10:14,960 --> 01:10:18,160 Speaker 1: up to forty nine feet fifteen meters long, so an 1209 01:10:18,160 --> 01:10:20,720 Speaker 1: adult human would would fall short of the knee. So 1210 01:10:20,800 --> 01:10:24,680 Speaker 1: this was one of the largest carnosaur dinosaurs uh and one, 1211 01:10:24,800 --> 01:10:28,120 Speaker 1: and therefore one of the largest terrestrial carnivores ever to 1212 01:10:28,200 --> 01:10:30,760 Speaker 1: walk the Earth. Yeah. I think it's just the Spinosaurus 1213 01:10:30,800 --> 01:10:33,320 Speaker 1: and the Gigantosaurus up there with it. Yeah, yeah, I 1214 01:10:33,360 --> 01:10:37,519 Speaker 1: believe so. And it's a It's diet probably primarily dependent 1215 01:10:37,600 --> 01:10:42,479 Speaker 1: on duck build hadrosaurs and for a while paleontologists drifted 1216 01:10:42,520 --> 01:10:45,280 Speaker 1: towards uh, when I tend to think of as a 1217 01:10:45,360 --> 01:10:48,680 Speaker 1: bully scavenger view of the beast. So so, it's this 1218 01:10:48,920 --> 01:10:53,280 Speaker 1: enormous creature obviously, but there were there were theories about 1219 01:10:53,320 --> 01:10:56,599 Speaker 1: its its size and its speed that made the paleonta 1220 01:10:56,800 --> 01:10:58,640 Speaker 1: to say, well, maybe what this thing did is it 1221 01:10:58,760 --> 01:11:02,639 Speaker 1: just scared away the predators from an existing kill. That's 1222 01:11:02,680 --> 01:11:04,639 Speaker 1: my corps get away from it. Yeah, And who's gonna 1223 01:11:04,640 --> 01:11:07,639 Speaker 1: stop t rex? Because once in this theory, this view 1224 01:11:07,680 --> 01:11:10,519 Speaker 1: of a of a slow t rex, once it ambles up, 1225 01:11:11,000 --> 01:11:13,360 Speaker 1: you better eating all you can eat, because it's it's 1226 01:11:13,400 --> 01:11:16,840 Speaker 1: gonna get whatever it wants at that point. Now, opinions varied, 1227 01:11:16,960 --> 01:11:20,520 Speaker 1: but over time the consensus drifted back towards the apex 1228 01:11:20,560 --> 01:11:23,479 Speaker 1: predator model of the t rex, the saying that it 1229 01:11:23,600 --> 01:11:26,759 Speaker 1: likely hit among the trees and then ran full force 1230 01:11:26,960 --> 01:11:30,160 Speaker 1: jaws open at its prey. Uh. And it's certainly had 1231 01:11:30,240 --> 01:11:33,320 Speaker 1: encounters with triceratops as well, which we'll get to. And 1232 01:11:33,360 --> 01:11:35,839 Speaker 1: of course that's our our next combatant in this battle, 1233 01:11:36,000 --> 01:11:38,640 Speaker 1: the triceratops. Now, you might put up for the stigasaur, 1234 01:11:38,760 --> 01:11:44,040 Speaker 1: but I think triceratops is the most widely beloved herbivore dinosaur. 1235 01:11:45,000 --> 01:11:47,320 Speaker 1: I think there's a there's a very strong case for 1236 01:11:47,400 --> 01:11:50,200 Speaker 1: that being true. Yeah, I mean it's it's it's you 1237 01:11:50,280 --> 01:11:52,320 Speaker 1: just look at it and you can tell that this 1238 01:11:52,400 --> 01:11:55,960 Speaker 1: is this is an animal you're behind and to go 1239 01:11:56,000 --> 01:11:59,080 Speaker 1: back to Jurassic Park. Uh. Stegosaurus I don't think made 1240 01:11:59,120 --> 01:12:03,679 Speaker 1: it into the film, but tri sarratops Is is prominently featured. 1241 01:12:03,960 --> 01:12:07,240 Speaker 1: All the human cast members, maybe except for Jeff Goldblum, 1242 01:12:07,280 --> 01:12:09,439 Speaker 1: I think, are hugging on it and touching it because 1243 01:12:09,439 --> 01:12:13,240 Speaker 1: it's laying there recovering from its illness. Surely getting some 1244 01:12:13,280 --> 01:12:17,080 Speaker 1: staff infections from that thing. Yeah. Meanwhile, Stegosaurus is off 1245 01:12:17,160 --> 01:12:20,720 Speaker 1: camera asking hey, what about my scene? Stephen? When when 1246 01:12:20,760 --> 01:12:23,080 Speaker 1: do I go on? And Steven Spielberg is like, uh, 1247 01:12:23,360 --> 01:12:25,720 Speaker 1: they did, well just a minute, we're we have to 1248 01:12:25,720 --> 01:12:27,559 Speaker 1: do this scene. I think they show up in the 1249 01:12:27,600 --> 01:12:31,439 Speaker 1: sequel in the Lost World, do they? Yeah, I remember correctly. 1250 01:12:31,439 --> 01:12:33,960 Speaker 1: I think that they're somebody's taking a picture of one 1251 01:12:34,360 --> 01:12:37,320 Speaker 1: and the Stegosaurus becomes disturbed by the loud noise that 1252 01:12:37,360 --> 01:12:41,120 Speaker 1: the camera makes while it's winding its film back. Okay, alright, 1253 01:12:41,160 --> 01:12:43,760 Speaker 1: good to know, good to know. So the tri Steratops 1254 01:12:43,920 --> 01:12:48,439 Speaker 1: late Cretaceous North American thirty ft nine meters long, the 1255 01:12:48,479 --> 01:12:51,680 Speaker 1: most famous of the horned dinosaurs, also the largest and 1256 01:12:51,720 --> 01:12:54,759 Speaker 1: the most abundant, so they lived in herds across North America. 1257 01:12:55,040 --> 01:12:57,960 Speaker 1: And unlike the net frills of other horned dinosaurs, and 1258 01:12:57,960 --> 01:13:01,600 Speaker 1: there are several varieties and even some sub varieties of 1259 01:13:01,640 --> 01:13:05,800 Speaker 1: Triceratops here, Unlike these others, though, this frill was solid bone, 1260 01:13:05,880 --> 01:13:08,920 Speaker 1: a defensive structure to protect the neck. And we have 1261 01:13:09,000 --> 01:13:12,879 Speaker 1: fossil evidence of encounters between Triceratops and t Rex, including 1262 01:13:12,880 --> 01:13:18,000 Speaker 1: evidence of partially healed tyrannosaur tooth marks on a triceratops 1263 01:13:18,000 --> 01:13:21,000 Speaker 1: brow horn. Whoa healed and now that means it it 1264 01:13:21,400 --> 01:13:24,679 Speaker 1: met a t Rex and went and lived to tell 1265 01:13:24,720 --> 01:13:27,760 Speaker 1: the tale exactly it either it at least drove the 1266 01:13:27,760 --> 01:13:32,880 Speaker 1: creature away or managed to escape and maybe even lethally interested, 1267 01:13:33,000 --> 01:13:36,760 Speaker 1: who knows, but either way the message seems to be Triceratops, 1268 01:13:36,880 --> 01:13:40,080 Speaker 1: when it encountered t Rex, it was capable of holding 1269 01:13:40,120 --> 01:13:42,639 Speaker 1: its own at least in some cases. Because of course, 1270 01:13:42,640 --> 01:13:46,680 Speaker 1: you're also gonna have varying situations of age and size, right, 1271 01:13:46,920 --> 01:13:51,719 Speaker 1: like a young um, a young tristerotopes encountering older t rex, 1272 01:13:52,000 --> 01:13:55,760 Speaker 1: which I understand plays into Karen Wallace's I Am a 1273 01:13:55,800 --> 01:13:59,000 Speaker 1: Tyrannosaurus Rex, and I think that's why every That's one 1274 01:13:59,040 --> 01:14:01,200 Speaker 1: of the reasons some of the the reviews were so 1275 01:14:02,320 --> 01:14:04,960 Speaker 1: critical is that I don't know for sure because I 1276 01:14:04,960 --> 01:14:07,080 Speaker 1: haven't read it, but I think the t rex kills 1277 01:14:07,200 --> 01:14:11,360 Speaker 1: try stereotops. This is like the grail legend king version 1278 01:14:11,400 --> 01:14:14,320 Speaker 1: of the Tyrannosaurus Rex, the king whose strength is failing. 1279 01:14:15,280 --> 01:14:19,240 Speaker 1: Uh okay, So where's the fossil evidence? Where where do 1280 01:14:19,240 --> 01:14:24,200 Speaker 1: we actually have an encounter between these two creatures. Well, 1281 01:14:24,320 --> 01:14:27,000 Speaker 1: we do have what has been referred to as the 1282 01:14:27,040 --> 01:14:31,559 Speaker 1: Montana dooling dinosaurs, and this is from about sixty eight 1283 01:14:31,600 --> 01:14:36,799 Speaker 1: million years ago. Now here's a little fine print. UM. 1284 01:14:36,840 --> 01:14:39,680 Speaker 1: Based on interpretation, seems like what we have here is 1285 01:14:39,680 --> 01:14:45,160 Speaker 1: an encounter between the smaller nano Tyrannis, which is a 1286 01:14:45,280 --> 01:14:48,960 Speaker 1: close relative of the t rex, though some people argue 1287 01:14:48,960 --> 01:14:51,479 Speaker 1: that this might be a juvenile t Rex tiny enough 1288 01:14:51,520 --> 01:14:57,559 Speaker 1: to be injected into your bloodstream attack your DNA directly. Yeah, 1289 01:14:57,600 --> 01:14:59,960 Speaker 1: well not not that small. Don't let the nano foo, 1290 01:15:00,000 --> 01:15:02,639 Speaker 1: will you? Um? Dino scale is still in play, but 1291 01:15:02,640 --> 01:15:06,000 Speaker 1: but certainly a smaller t Rex. And then the other 1292 01:15:06,080 --> 01:15:11,240 Speaker 1: creature uh is Casmio Sarine Saratopsian, and this would have 1293 01:15:11,280 --> 01:15:15,360 Speaker 1: been from the Triceratops family, but smaller. Though some people 1294 01:15:15,479 --> 01:15:17,559 Speaker 1: are commenting on this fossil, go ahead and call it 1295 01:15:17,640 --> 01:15:21,439 Speaker 1: a Triceratops based on what we've seen of this fossil, 1296 01:15:21,479 --> 01:15:24,160 Speaker 1: let's believe that the two dinos killed each other in battle. 1297 01:15:24,360 --> 01:15:27,519 Speaker 1: T Rex suffered a crushed skull and chest, and its 1298 01:15:27,520 --> 01:15:31,519 Speaker 1: teeth pierced the horned one's skull as well. They were buried, 1299 01:15:31,760 --> 01:15:36,120 Speaker 1: probably by an earthquake because the theories like an earthquake happen, 1300 01:15:36,320 --> 01:15:38,599 Speaker 1: So they died and their bodies were there and then 1301 01:15:38,640 --> 01:15:41,519 Speaker 1: an earthquake buried them. Or does it look like the 1302 01:15:41,520 --> 01:15:44,200 Speaker 1: earthquake was going on while they were fighting. I don't 1303 01:15:44,280 --> 01:15:47,400 Speaker 1: want it to be the last either. Interpretation is pretty amazing, 1304 01:15:47,520 --> 01:15:51,080 Speaker 1: like you think of your most cinematic battles between hero 1305 01:15:51,520 --> 01:15:55,559 Speaker 1: and villain. Does it ever end in both characters killing 1306 01:15:55,560 --> 01:15:58,280 Speaker 1: each other and then a volcano erupts and covers them, 1307 01:15:58,400 --> 01:16:02,240 Speaker 1: or or an earthquake swallows them hold or a mudslide 1308 01:16:02,400 --> 01:16:04,679 Speaker 1: buries them like that kind of thing is rare even 1309 01:16:04,680 --> 01:16:10,200 Speaker 1: in our most uh you know, imagine fictional showdowns, modern 1310 01:16:10,360 --> 01:16:13,040 Speaker 1: modern stories. You don't want the hero to die usually. 1311 01:16:13,560 --> 01:16:16,240 Speaker 1: I mean, what do they have, like Sherlock Holmes and Moriarty, 1312 01:16:16,360 --> 01:16:18,960 Speaker 1: like plunge to their death together or something that would 1313 01:16:18,960 --> 01:16:21,919 Speaker 1: be a pretty awesome fossil Can you imagine a future 1314 01:16:22,000 --> 01:16:26,080 Speaker 1: generation of intelligent squid creatures looking through the fossil record 1315 01:16:26,120 --> 01:16:28,120 Speaker 1: of humanity and they say, well, we don't have a 1316 01:16:28,160 --> 01:16:31,000 Speaker 1: lot to go on about human on human combat, but 1317 01:16:31,080 --> 01:16:34,960 Speaker 1: we do have the Sherlock Moriarty fossil fine and it's amazing, 1318 01:16:36,280 --> 01:16:39,439 Speaker 1: and it's got this opium pipe you know. Oh yeah, 1319 01:16:40,479 --> 01:16:43,960 Speaker 1: uh so um. This particular fine though, the Montana doling 1320 01:16:44,000 --> 01:16:48,960 Speaker 1: dinosaurs is is pretty controversial. So it was unearthed by 1321 01:16:49,160 --> 01:16:52,919 Speaker 1: fossil hunters. Fossil hunters that were not working on behalf 1322 01:16:53,000 --> 01:16:57,400 Speaker 1: of you know, scientific organization or a museum. They found 1323 01:16:57,400 --> 01:16:59,000 Speaker 1: this thing, They dug it up, and then they tried 1324 01:16:59,040 --> 01:17:02,960 Speaker 1: to sell the rock embedded fossils at auction for eight 1325 01:17:03,000 --> 01:17:06,200 Speaker 1: to ten million dollars. Yeah. So the idea was to 1326 01:17:06,240 --> 01:17:09,960 Speaker 1: snag a wealthy and fossil enthusiast who then might donate 1327 01:17:10,000 --> 01:17:13,120 Speaker 1: it to a museum. Uh, it ended up failing to 1328 01:17:13,160 --> 01:17:17,400 Speaker 1: sell it auction into in and uh the thing was 1329 01:17:17,520 --> 01:17:20,880 Speaker 1: valued at seven to nine million dollars, but bidding only 1330 01:17:20,920 --> 01:17:24,519 Speaker 1: reached five point five million. So they just put it 1331 01:17:24,560 --> 01:17:28,360 Speaker 1: into into storage, into a vault. And that's that's where 1332 01:17:28,360 --> 01:17:31,599 Speaker 1: it is today now to give all that's that's sad, 1333 01:17:31,760 --> 01:17:35,040 Speaker 1: that's junk. Yeah. Uh so how did this even come 1334 01:17:35,160 --> 01:17:38,320 Speaker 1: come to pass? Well, you have to look back a 1335 01:17:38,320 --> 01:17:44,160 Speaker 1: little to you know, the post Jurassic Park zeal for dinosaurs. Okay, 1336 01:17:44,520 --> 01:17:47,200 Speaker 1: uh and uh in particular, there was a t rex 1337 01:17:47,479 --> 01:17:50,840 Speaker 1: skeleton uh named Sue this one moment up for bidding 1338 01:17:50,840 --> 01:17:53,040 Speaker 1: and it was valued about a million dollars, but the 1339 01:17:53,040 --> 01:17:55,800 Speaker 1: Field Museum of Natural History purchased it for eight point 1340 01:17:55,960 --> 01:17:59,280 Speaker 1: four million. And so critics have said, well, this was 1341 01:17:59,360 --> 01:18:02,960 Speaker 1: kind of the start of the dinosaur gold rush. You've 1342 01:18:02,960 --> 01:18:05,639 Speaker 1: got into people's mind if we find a really awesome fossil, 1343 01:18:05,680 --> 01:18:09,559 Speaker 1: so find we can sell it, you know, at high 1344 01:18:09,560 --> 01:18:12,040 Speaker 1: price to the highest bidder, and then they can they 1345 01:18:12,080 --> 01:18:14,160 Speaker 1: can do the science once we've done that. But first 1346 01:18:14,200 --> 01:18:16,919 Speaker 1: we're gonna get we're gonna get our our our payday. 1347 01:18:18,439 --> 01:18:20,599 Speaker 1: And this area discussion reminds me a lot of the 1348 01:18:20,680 --> 01:18:25,400 Speaker 1: meteorite hunter debate. So when when profit chasing hunters are 1349 01:18:25,439 --> 01:18:29,560 Speaker 1: the ones finding scientifically significant rocks instead of the scientist, 1350 01:18:30,280 --> 01:18:34,559 Speaker 1: then all sorts of problems emerge. Proper identification, proper protection 1351 01:18:34,640 --> 01:18:37,640 Speaker 1: of the find, proper values placed on the rocks, not 1352 01:18:37,680 --> 01:18:41,400 Speaker 1: to mention, opening the door to fossil or meteorite theft, 1353 01:18:41,400 --> 01:18:45,240 Speaker 1: to black markets, to rock squatting, as we see with 1354 01:18:46,640 --> 01:18:48,679 Speaker 1: with the with the idea of this, this fossil find 1355 01:18:48,760 --> 01:18:52,439 Speaker 1: just landing in a vault until somebody ponies up enough money. Um. 1356 01:18:53,040 --> 01:18:56,479 Speaker 1: The falsification is pretty interesting to consider that Nicolas Cage, 1357 01:18:56,840 --> 01:19:00,360 Speaker 1: the actor, paid two hundred and seventy six thousand hours 1358 01:19:00,360 --> 01:19:03,240 Speaker 1: in an auction in twenty two seven for a t 1359 01:19:03,479 --> 01:19:06,160 Speaker 1: rex skull, a skull that turned out to have been 1360 01:19:06,200 --> 01:19:09,200 Speaker 1: illegally removed from Mongolia and he had to return it. 1361 01:19:10,320 --> 01:19:14,560 Speaker 1: That's Nick, you should be ashamed of yourself. Well, he 1362 01:19:15,080 --> 01:19:18,519 Speaker 1: turned he did the right thing, the Nick credit. Well, 1363 01:19:18,560 --> 01:19:21,560 Speaker 1: I guess so, I'm sorry. I don't mean to be vindictive, 1364 01:19:21,960 --> 01:19:24,960 Speaker 1: he I. I think when you first told me about this, Robert, 1365 01:19:25,000 --> 01:19:28,000 Speaker 1: I imagined him reading an apology letter in his can 1366 01:19:28,040 --> 01:19:31,840 Speaker 1: air accent as I just recently rewatched that movie. Well, 1367 01:19:31,880 --> 01:19:34,320 Speaker 1: the headline on the CNN piece that I sent about 1368 01:19:34,360 --> 01:19:39,880 Speaker 1: that um um the title was I think Nicholas Cage 1369 01:19:40,200 --> 01:19:43,120 Speaker 1: returns his t rex skull, which kind of implied that 1370 01:19:43,200 --> 01:19:45,519 Speaker 1: the skull inside his head was that of a t rex, 1371 01:19:45,640 --> 01:19:48,480 Speaker 1: which I kind of like. By the way, that CNN 1372 01:19:48,560 --> 01:19:52,120 Speaker 1: article reported that quote, he bought the tyronos Are skull 1373 01:19:52,240 --> 01:19:56,040 Speaker 1: during a time when he also bought fifteen mansions, two castles, 1374 01:19:56,240 --> 01:20:00,759 Speaker 1: four yachts, and nine rolls royces. So you know, sometimes 1375 01:20:00,800 --> 01:20:03,840 Speaker 1: you go on a spending uh spree and you make 1376 01:20:03,880 --> 01:20:07,519 Speaker 1: a few questionable purchase in purchases, including maybe a stolen 1377 01:20:07,520 --> 01:20:10,520 Speaker 1: Mongolian t rex skull. Well, if you're going for opulence 1378 01:20:10,560 --> 01:20:15,439 Speaker 1: and violating the world's right to preservation of natural history, 1379 01:20:16,320 --> 01:20:18,479 Speaker 1: I think you should just go all out, not you know, 1380 01:20:18,520 --> 01:20:22,120 Speaker 1: skip fourteen in the mansions and instead have one castle 1381 01:20:22,400 --> 01:20:27,360 Speaker 1: made out of t rex skulls. Uh. Well, basically, I 1382 01:20:27,360 --> 01:20:30,040 Speaker 1: would say the big take home here is that sadly 1383 01:20:30,560 --> 01:20:35,679 Speaker 1: the Montana dueling dinosaurs uh find uh has not received 1384 01:20:35,680 --> 01:20:39,840 Speaker 1: the actual scrutiny that it deserves. And if there's a 1385 01:20:39,880 --> 01:20:43,120 Speaker 1: plus side though, the failure of of this and I 1386 01:20:43,120 --> 01:20:45,960 Speaker 1: think there was a Stegasaurus find that also failed to 1387 01:20:45,960 --> 01:20:49,439 Speaker 1: to to bring in the dough that the hunters wanted. 1388 01:20:50,040 --> 01:20:53,679 Speaker 1: These you could indicate that the fossil bubble has burst 1389 01:20:53,880 --> 01:20:55,880 Speaker 1: and you'll see less of this in the future, So 1390 01:20:56,120 --> 01:21:00,720 Speaker 1: fossil hunters will hopefully be more you influenced by the 1391 01:21:00,760 --> 01:21:05,720 Speaker 1: desire to to get these fines to two institutions and experts, 1392 01:21:05,960 --> 01:21:09,559 Speaker 1: as opposed to just making a massive payday off. Yeah. 1393 01:21:09,680 --> 01:21:12,760 Speaker 1: I mean, maybe I'm just not being sympathetic enough to 1394 01:21:12,840 --> 01:21:15,040 Speaker 1: see the other side of the coin. But to me, 1395 01:21:15,080 --> 01:21:18,280 Speaker 1: it seems like, I don't know, relics of past geological 1396 01:21:18,400 --> 01:21:21,360 Speaker 1: eras seem like the common heritage of humanity. Shouldn't they 1397 01:21:21,400 --> 01:21:23,439 Speaker 1: be in a place where open to the public, where 1398 01:21:23,439 --> 01:21:27,160 Speaker 1: people can come and see them. Yeah, but but then again, 1399 01:21:27,200 --> 01:21:28,839 Speaker 1: but of course they need to get down to the question. 1400 01:21:28,880 --> 01:21:32,360 Speaker 1: While if that fossil relic is in Mongolia at a museum, 1401 01:21:32,720 --> 01:21:35,320 Speaker 1: not everybody gets to see that. If that fossil relic 1402 01:21:35,439 --> 01:21:38,000 Speaker 1: is in Chicago, not everyone gets to see that. Yeah, 1403 01:21:38,120 --> 01:21:40,640 Speaker 1: but that's better than being in a private it's in 1404 01:21:40,680 --> 01:21:43,160 Speaker 1: a private vault, like virtually nobody gets to see that, 1405 01:21:43,240 --> 01:21:47,839 Speaker 1: and that doesn't benefit anyone. But still, this fossil exists 1406 01:21:47,960 --> 01:21:51,240 Speaker 1: and that that is exciting. So maybe one day, uh 1407 01:21:52,200 --> 01:21:53,920 Speaker 1: kids will get to see it in a museum and 1408 01:21:54,160 --> 01:21:58,519 Speaker 1: paleontologist will get to give it a lot more attention hopefully. 1409 01:21:58,520 --> 01:22:02,280 Speaker 1: So all right, Robert, you got anything else about fossil 1410 01:22:02,320 --> 01:22:05,280 Speaker 1: action scenes? No, I think that the card has concluded. 1411 01:22:05,320 --> 01:22:08,599 Speaker 1: The main event has concluded. Uh we we've people are 1412 01:22:08,680 --> 01:22:11,559 Speaker 1: throwing their beer cups down into the ring, right, everyone's 1413 01:22:11,840 --> 01:22:16,160 Speaker 1: piling out of the the the cretaceous thunder dome here, 1414 01:22:17,000 --> 01:22:19,120 Speaker 1: and uh yeah, we're left to just consider just the 1415 01:22:19,400 --> 01:22:22,120 Speaker 1: just how amazing it is. First of all that fossils exist, 1416 01:22:22,560 --> 01:22:25,000 Speaker 1: like the the the the string of events that have 1417 01:22:25,080 --> 01:22:28,920 Speaker 1: to take place to reach fossilization and and then recovery 1418 01:22:29,120 --> 01:22:32,760 Speaker 1: and appreciation by modern humans. But then to consider that, yes, 1419 01:22:32,800 --> 01:22:37,719 Speaker 1: we have these amazing moments from life, violent confrontations, mating, 1420 01:22:38,120 --> 01:22:41,760 Speaker 1: uh and even birth preserved in the fossil record. And 1421 01:22:42,000 --> 01:22:43,920 Speaker 1: I do I've said this on the podcast before, but 1422 01:22:43,960 --> 01:22:45,840 Speaker 1: I do just want to say again, if you've never 1423 01:22:46,240 --> 01:22:48,599 Speaker 1: had the chance to go to a good natural history 1424 01:22:48,680 --> 01:22:52,160 Speaker 1: museum and look at fossil exhibits, you should find a 1425 01:22:52,200 --> 01:22:54,920 Speaker 1: way to do this. It it is worth it. It's 1426 01:22:54,960 --> 01:22:58,040 Speaker 1: so cool, it's it's a life changing experience to really 1427 01:22:58,080 --> 01:23:01,559 Speaker 1: see dinosaur fossils in person. Indeed, and if you want 1428 01:23:01,560 --> 01:23:03,360 Speaker 1: to check out those books that we read from at 1429 01:23:03,360 --> 01:23:07,000 Speaker 1: the beginning, again, those are by Karen Wallace. There's I 1430 01:23:07,080 --> 01:23:12,080 Speaker 1: Am a Diplodocus, I Am a quetzal Coatlas, and then 1431 01:23:12,080 --> 01:23:17,559 Speaker 1: she also has one on Ankleiosaurus Tyrannosaurus. Uh and uh yeah, 1432 01:23:17,640 --> 01:23:19,960 Speaker 1: I think that's it. Yeah, yeah, they'll be prepared for 1433 01:23:20,000 --> 01:23:22,680 Speaker 1: the carnage. Be prepared for the carnage. Come for the carnage, 1434 01:23:23,479 --> 01:23:25,080 Speaker 1: all right. In the meantime, if you want to check 1435 01:23:25,120 --> 01:23:29,080 Speaker 1: out various other podcast episodes we've done, head a numbers 1436 01:23:29,120 --> 01:23:30,880 Speaker 1: stuff to blow your mind dot com.
