1 00:00:03,040 --> 00:00:05,840 Speaker 1: Welcome to Stuff to Blow your Mind from how Stuff 2 00:00:05,840 --> 00:00:14,239 Speaker 1: Works dot com. Hey are you welcome to Stuff to 3 00:00:14,240 --> 00:00:16,280 Speaker 1: Blow your Mind? My name is Robert Land, and I'm 4 00:00:16,320 --> 00:00:18,960 Speaker 1: Joe McCormick. Joe, what was your favorite dinosaur when you 5 00:00:19,000 --> 00:00:22,919 Speaker 1: were a child. That is an impossible question. It's impossible, 6 00:00:23,160 --> 00:00:26,080 Speaker 1: you know. I think my favorite was actually the fake 7 00:00:26,320 --> 00:00:30,680 Speaker 1: velociraptors from Jurassic Park, which are you know? The philociraptors 8 00:00:30,720 --> 00:00:33,480 Speaker 1: in Jurassic Park are not really much like real velociraptors. 9 00:00:33,640 --> 00:00:37,360 Speaker 1: There are more number of reasons. Yes, they're probably closer 10 00:00:37,400 --> 00:00:41,040 Speaker 1: to the dinosaur Dinonicus, right, but I was really into 11 00:00:41,080 --> 00:00:44,479 Speaker 1: them as far as real dinosaurs go. You know, your 12 00:00:44,479 --> 00:00:47,199 Speaker 1: triceratops as a fan favorite, it seems kind of like 13 00:00:47,240 --> 00:00:50,920 Speaker 1: the the workhorse protagonist of your dinosaur paleo art scene 14 00:00:50,960 --> 00:00:54,320 Speaker 1: where you've got a predator attacking and a triceratops defending 15 00:00:54,400 --> 00:00:57,319 Speaker 1: and volcanoes erupting in the background. So it always made 16 00:00:57,320 --> 00:01:00,200 Speaker 1: the triceratops look like the good guy, like the would 17 00:01:00,240 --> 00:01:03,520 Speaker 1: one while there was a ferocious tyrannosaur. It's also, I 18 00:01:03,520 --> 00:01:05,640 Speaker 1: don't know, predators are fun. It's it's hard to turn 19 00:01:05,680 --> 00:01:08,120 Speaker 1: down a Tyrannosaur. Well, I like your point about it 20 00:01:08,160 --> 00:01:12,240 Speaker 1: being impossible to pick a favorite, because ultimately, for a child, 21 00:01:12,560 --> 00:01:17,240 Speaker 1: dinosaurs are are less a roster of prehistoric creatures or 22 00:01:17,720 --> 00:01:20,840 Speaker 1: or a tree of prehistoric creatures. They're they're more a pantheon. 23 00:01:21,319 --> 00:01:23,679 Speaker 1: You know. They have different energies to them, they have 24 00:01:23,760 --> 00:01:27,200 Speaker 1: different roles, and you have to sort of love them 25 00:01:27,240 --> 00:01:30,440 Speaker 1: all because they all embody this this sort of wild 26 00:01:30,600 --> 00:01:34,400 Speaker 1: nature that I think the child, more than any of us, 27 00:01:34,400 --> 00:01:37,720 Speaker 1: certainly I mean more than us adults, is in touch with. Well, yeah, 28 00:01:37,720 --> 00:01:39,360 Speaker 1: that they do have a character, Like I was saying, 29 00:01:39,400 --> 00:01:44,319 Speaker 1: the tri Saratops very much has this kind of, uh straightforward, goodhearted, 30 00:01:44,400 --> 00:01:48,320 Speaker 1: working class hero kind of vibe. And the Dynonicus or 31 00:01:48,320 --> 00:01:51,200 Speaker 1: the velociraptor they're kind of sneaky, aren't they. Then how 32 00:01:51,240 --> 00:01:55,240 Speaker 1: would you classify the star of today's episode, the Mighty 33 00:01:55,320 --> 00:02:01,400 Speaker 1: Stegasaurus good natured, dimwitted sidekick from psychick, Yeah, sidekick, not 34 00:02:01,520 --> 00:02:05,000 Speaker 1: psychicked sidekick? No, Like the character out of this has 35 00:02:05,000 --> 00:02:07,040 Speaker 1: got to be an archetype in some movies, like the 36 00:02:08,000 --> 00:02:11,720 Speaker 1: character who's on the good side, who's friends with the protagonist, 37 00:02:11,960 --> 00:02:16,840 Speaker 1: who's maybe not too bright and like has some malapropisms, okay, 38 00:02:16,919 --> 00:02:20,280 Speaker 1: but I can also easily see the stegosaurs taking the central, dimwitted, 39 00:02:20,320 --> 00:02:23,160 Speaker 1: strong hero role of say a like a Hercules or 40 00:02:23,200 --> 00:02:27,160 Speaker 1: a or a Samson Conan. Yeah, oh that I've never 41 00:02:27,200 --> 00:02:29,880 Speaker 1: thought about it that way, but the tiny headed stegosaurus 42 00:02:30,480 --> 00:02:32,600 Speaker 1: very much could be the conan, the barbarian of the 43 00:02:32,600 --> 00:02:35,359 Speaker 1: prehistoric world, you know, like Chrome. I've never prayed to 44 00:02:35,360 --> 00:02:37,720 Speaker 1: you before. I have no tongue for it, but if 45 00:02:37,720 --> 00:02:41,560 Speaker 1: you let me thagomize my enemies, Yeah, indeed. And he's 46 00:02:41,600 --> 00:02:43,840 Speaker 1: got the armor, he's got the muscles, and he's got 47 00:02:43,880 --> 00:02:46,799 Speaker 1: that awesome weapon that he swings around. I want to 48 00:02:46,919 --> 00:02:51,120 Speaker 1: run some true dinosaur facts by you today because we 49 00:02:51,160 --> 00:02:55,040 Speaker 1: are going to be talking about some some dinosaurs pseudoscience 50 00:02:55,600 --> 00:02:57,960 Speaker 1: in the in the probably the second half of the 51 00:02:58,000 --> 00:03:01,720 Speaker 1: episode for sure. Yeah. So these are all one true facts. 52 00:03:01,720 --> 00:03:05,560 Speaker 1: I'm about to state. It can be proved that dinosaurs 53 00:03:05,600 --> 00:03:09,920 Speaker 1: are still alive today. They exist on every continent on 54 00:03:09,960 --> 00:03:13,800 Speaker 1: the Earth. There are literally even millions of dinosaurs currently 55 00:03:13,880 --> 00:03:17,480 Speaker 1: living in Antarctica. Thousands of people are maybe millions of 56 00:03:17,520 --> 00:03:21,080 Speaker 1: people for all I know, actually even keep dinosaurs as pets. 57 00:03:21,160 --> 00:03:23,160 Speaker 1: You might not have ever known about this, that they 58 00:03:23,240 --> 00:03:26,520 Speaker 1: keep dinosaurs as pets in cages, and sometimes they can 59 00:03:26,560 --> 00:03:30,480 Speaker 1: even train these dinosaurs to speak modern languages and repeat 60 00:03:30,520 --> 00:03:37,280 Speaker 1: phrases like poly wanna cracker. Those statements again a true 61 00:03:37,680 --> 00:03:40,360 Speaker 1: and certainly you can you can take them all in 62 00:03:40,440 --> 00:03:44,520 Speaker 1: kind of a dinatopia, uh spirit, where we imagine this 63 00:03:44,640 --> 00:03:49,960 Speaker 1: fantastic world full of antarctic dinosaurs and and pet velociraptors. 64 00:03:50,040 --> 00:03:53,320 Speaker 1: But uh, but but this is this is all a 65 00:03:53,440 --> 00:03:57,160 Speaker 1: much more mundane fact of our reality. Right. I'm actually 66 00:03:57,160 --> 00:04:00,280 Speaker 1: being pedantic and obnoxious because these are all true acts. 67 00:04:00,320 --> 00:04:06,600 Speaker 1: Because birds are dinosaurs. Modern birds are biologically considered dinosaurs 68 00:04:06,600 --> 00:04:09,960 Speaker 1: in terms of phylogenetic analysis. Uh So hate me if 69 00:04:09,960 --> 00:04:12,320 Speaker 1: you want, but it's true. And because we're gonna be 70 00:04:12,320 --> 00:04:15,680 Speaker 1: talking about the concept of modern or recent dinosaurs today 71 00:04:15,760 --> 00:04:18,320 Speaker 1: and some pseudo scientific beliefs associated with that, I have 72 00:04:18,400 --> 00:04:20,800 Speaker 1: to say, as a precaution against getting a lot of 73 00:04:20,800 --> 00:04:24,640 Speaker 1: potential pedantic emails, I'll go ahead and be pedantic for you. 74 00:04:24,960 --> 00:04:27,320 Speaker 1: When we talk about dinosaurs in this episode, we're talking 75 00:04:27,320 --> 00:04:31,200 Speaker 1: about the classic kind, the non avian dinosaurs, the last 76 00:04:31,200 --> 00:04:33,599 Speaker 1: of which went extinct at the end of the Cretaceous 77 00:04:33,600 --> 00:04:36,920 Speaker 1: period about sixty six million years ago. But modern day 78 00:04:36,960 --> 00:04:40,520 Speaker 1: birds are the descendants of the only dinosaurs that survived 79 00:04:40,640 --> 00:04:43,760 Speaker 1: this horrible mass extinction, in which about three quarters of 80 00:04:43,800 --> 00:04:47,800 Speaker 1: Earth's plant and animal species suddenly disappeared. Those dinosaurs that 81 00:04:47,839 --> 00:04:52,120 Speaker 1: survived became birds, and thus birds of today are dinosaurs. 82 00:04:52,480 --> 00:04:54,520 Speaker 1: So when someone says, hey, I wonder what what would 83 00:04:54,560 --> 00:04:56,880 Speaker 1: what it would have been like if dinosaurs had survived 84 00:04:56,880 --> 00:04:59,760 Speaker 1: into modern times, they did. They did. Behold here they 85 00:04:59,760 --> 00:05:03,040 Speaker 1: are dinosaurs poop on your car. It's just true. They 86 00:05:03,080 --> 00:05:07,360 Speaker 1: build nests in your shed, They fly into your home 87 00:05:07,400 --> 00:05:10,200 Speaker 1: depot and eat bird seed out of the home and 88 00:05:10,240 --> 00:05:13,120 Speaker 1: garden section. Yeah, there's a dinosaur stuck in the home depot, 89 00:05:13,440 --> 00:05:15,960 Speaker 1: going back and forth between the aisles. My cat is 90 00:05:15,960 --> 00:05:19,160 Speaker 1: out in the backyard hunting dinosaurs. And this is all 91 00:05:19,200 --> 00:05:22,039 Speaker 1: fun to say for multiple reasons, mainly maybe because we 92 00:05:22,120 --> 00:05:24,719 Speaker 1: all love us some flint stones right where humans and 93 00:05:24,800 --> 00:05:28,280 Speaker 1: dinosaurs they exist at the same time, And dinosaurs are 94 00:05:28,320 --> 00:05:32,080 Speaker 1: brutally enslaved to serve as household appliances. So you've got 95 00:05:32,120 --> 00:05:35,800 Speaker 1: a dinosaur garbage disposal. Is there a dinosaur TV? Do 96 00:05:35,880 --> 00:05:38,640 Speaker 1: they just watch a dinosaur acting out TV shows or something? 97 00:05:38,640 --> 00:05:40,320 Speaker 1: I don't remember. I feel like they probably did have 98 00:05:40,360 --> 00:05:43,760 Speaker 1: a TV, but I can't. I can't instantly picture it 99 00:05:43,760 --> 00:05:47,400 Speaker 1: in my head. I think even most elementary school children 100 00:05:47,480 --> 00:05:52,000 Speaker 1: these days are aware that humans and dinosaurs, the non 101 00:05:52,000 --> 00:05:55,320 Speaker 1: avian dinosaurs actually never existed at the same time. That 102 00:05:55,440 --> 00:05:58,160 Speaker 1: that's like something that was maybe a little bit blurrier 103 00:05:58,279 --> 00:06:00,920 Speaker 1: when I was a kid, but I think that generally 104 00:06:00,960 --> 00:06:04,920 Speaker 1: made clear to children today. Yeah, my son has no 105 00:06:04,960 --> 00:06:06,280 Speaker 1: doubt about it. I mean part of it. I think 106 00:06:06,320 --> 00:06:08,440 Speaker 1: it's because he watched a lot of dinosaur trains, so 107 00:06:09,600 --> 00:06:12,680 Speaker 1: it might be possible then that dinosaurs spoke and had 108 00:06:13,440 --> 00:06:16,680 Speaker 1: a rail system that was able to travel back and 109 00:06:16,720 --> 00:06:20,880 Speaker 1: forth in dinosaur history, but they certainly did not live 110 00:06:20,920 --> 00:06:23,440 Speaker 1: alongside humans, right, So, as we were just saying, the 111 00:06:23,480 --> 00:06:26,400 Speaker 1: non avian dinosaurs all in extinct before or during the 112 00:06:26,400 --> 00:06:30,400 Speaker 1: Cretaceous paleo gene extinction event sometimes known as the KPg 113 00:06:30,680 --> 00:06:33,760 Speaker 1: or the KT extinction about sixty six million years ago, 114 00:06:34,000 --> 00:06:36,640 Speaker 1: and human beings have existed for far less than a 115 00:06:36,680 --> 00:06:39,120 Speaker 1: million years. If you want to get more specific than that. 116 00:06:39,200 --> 00:06:41,440 Speaker 1: There there are actually some interesting questions there, like it 117 00:06:41,480 --> 00:06:45,200 Speaker 1: can prove difficult to say exactly when Homo sapiens appeared, because, 118 00:06:45,240 --> 00:06:49,000 Speaker 1: of course, the transition from earlier species of bipedal hominids 119 00:06:49,040 --> 00:06:52,160 Speaker 1: to the anatomically modern human didn't happen overnight. But our 120 00:06:52,200 --> 00:06:55,120 Speaker 1: best guess is that Homo sapiens first emerged in Africa 121 00:06:55,240 --> 00:06:58,440 Speaker 1: roughly two hundred thousand to three hundred thousand years ago roughly. 122 00:06:59,000 --> 00:07:01,880 Speaker 1: And that's a difference of about sixty five million years 123 00:07:01,960 --> 00:07:04,479 Speaker 1: or so. It's a big difference, right, It's not like 124 00:07:04,520 --> 00:07:06,880 Speaker 1: you could fudge the numbers a little bit one way 125 00:07:06,960 --> 00:07:09,720 Speaker 1: or another and say, maybe there's a little bit of overlap. Like, 126 00:07:09,760 --> 00:07:11,760 Speaker 1: it's a big enough difference that there's no way to 127 00:07:11,840 --> 00:07:15,000 Speaker 1: do that. Based on all the evidence available to us, 128 00:07:15,040 --> 00:07:18,240 Speaker 1: there is pretty much zero chance of human interaction with 129 00:07:18,320 --> 00:07:22,200 Speaker 1: non avian dinosaurs. So what are we to make of 130 00:07:22,480 --> 00:07:25,520 Speaker 1: stories and and little bits of art and things like 131 00:07:25,560 --> 00:07:28,200 Speaker 1: that that people sometimes present to say, no, no, no, 132 00:07:28,720 --> 00:07:34,120 Speaker 1: you're wrong. Humans have seen living dinosaurs and here's the proof. Yeah, 133 00:07:34,200 --> 00:07:37,280 Speaker 1: And as the title of this episode does suggests, one 134 00:07:37,320 --> 00:07:40,840 Speaker 1: bit of proof that we're discussing here today but also 135 00:07:40,960 --> 00:07:43,640 Speaker 1: using as just an excuse to talk about the stegosaurs, 136 00:07:44,120 --> 00:07:46,800 Speaker 1: is this idea that there is a twelveth century carving 137 00:07:46,880 --> 00:07:51,360 Speaker 1: in modern day Cambodia all the Stegosaurus, again, fossils of 138 00:07:51,440 --> 00:07:55,520 Speaker 1: which were not officially discovered until eighteen seventy seven during 139 00:07:55,520 --> 00:08:00,400 Speaker 1: the so called Bone Wars in North America. So that 140 00:08:00,600 --> 00:08:04,480 Speaker 1: is the evidence that is presented. Um, we're not buying it, 141 00:08:04,560 --> 00:08:06,440 Speaker 1: but we will discuss it a little bit later in 142 00:08:06,480 --> 00:08:09,480 Speaker 1: the show. Right, So before we get to the twelfth 143 00:08:09,480 --> 00:08:12,960 Speaker 1: century Cambodian carving of a supposed Stegasaurus, we should look 144 00:08:13,000 --> 00:08:16,600 Speaker 1: at the stegosaurus itself, this powerful cone in of the 145 00:08:16,640 --> 00:08:20,880 Speaker 1: prehistoric world, this fascinating old herbivore with its plates and 146 00:08:20,920 --> 00:08:23,680 Speaker 1: its spikes and its tiny little head. I want to 147 00:08:23,720 --> 00:08:26,360 Speaker 1: know all about it, Robert, let's go in alright. Well, 148 00:08:26,560 --> 00:08:29,040 Speaker 1: like I said earlier, Stegasaurus was certainly one of my 149 00:08:29,120 --> 00:08:32,360 Speaker 1: favorites as a as a child. And my son, by 150 00:08:32,400 --> 00:08:35,400 Speaker 1: the way, he likes the stegosaurus, but he actually prefers 151 00:08:35,760 --> 00:08:39,760 Speaker 1: the Kintrasaurus, which is a smaller contemporary from East Africa. 152 00:08:39,880 --> 00:08:42,080 Speaker 1: Oh yeah, I believe, as far as I know, that's 153 00:08:42,080 --> 00:08:44,079 Speaker 1: the only one that was ever found in Africa, right 154 00:08:44,440 --> 00:08:47,840 Speaker 1: I believe. So yeah, So this one, if you're unfamiliar 155 00:08:47,880 --> 00:08:51,040 Speaker 1: with the with what this specimen probably looked like the 156 00:08:51,080 --> 00:08:54,480 Speaker 1: illustrations and the fossil reconstructions tend to show it with 157 00:08:54,880 --> 00:08:58,640 Speaker 1: typical bony plates roughly halfway down its back, and then 158 00:08:58,679 --> 00:09:01,160 Speaker 1: it has spikes, so it looks like a cross between 159 00:09:01,640 --> 00:09:05,599 Speaker 1: a proper stegasaurus and a pin cushion. But now I 160 00:09:05,600 --> 00:09:08,760 Speaker 1: should say that even though the Controsaurus was smaller, it 161 00:09:08,840 --> 00:09:11,560 Speaker 1: was still sixteen ft or five meters long, which is 162 00:09:11,559 --> 00:09:18,120 Speaker 1: still pretty enormous. A proper Stegasaurus Stegasaurus ungladas would have 163 00:09:18,160 --> 00:09:21,080 Speaker 1: reached thirty ft or nine meters in length and would 164 00:09:21,080 --> 00:09:23,400 Speaker 1: have weighed somewhere in the neighborhood of five point three 165 00:09:23,440 --> 00:09:27,160 Speaker 1: to seven tons. So this was a herbivore, and it 166 00:09:27,240 --> 00:09:30,040 Speaker 1: lived in what is now North America during the late Jurassic, 167 00:09:30,160 --> 00:09:35,240 Speaker 1: so roughly one sixty three five million years ago. Carnegie 168 00:09:35,280 --> 00:09:37,960 Speaker 1: Quarry at the US Dinosaur National Monument is a is 169 00:09:38,000 --> 00:09:40,640 Speaker 1: one of the places where you'll find a wealth of 170 00:09:40,640 --> 00:09:44,960 Speaker 1: Stegasaurus fossils. In fact, I was reading where one prominent 171 00:09:45,600 --> 00:09:49,280 Speaker 1: paleontologist had even complained at one point that the Stegasaurus 172 00:09:49,400 --> 00:09:53,560 Speaker 1: fossils were in the way of the sauropod fossils that 173 00:09:53,640 --> 00:09:57,360 Speaker 1: he wanted to to to fully examine. Oh, like, can 174 00:09:57,360 --> 00:09:59,800 Speaker 1: we get somebody in here to sweep all these stegasaurs 175 00:09:59,840 --> 00:10:02,280 Speaker 1: out the way? I just have we have a nuisance 176 00:10:02,280 --> 00:10:07,760 Speaker 1: Stegosaurus is here. So stegosaurians were part of a branch 177 00:10:07,880 --> 00:10:11,560 Speaker 1: of dinosaurs that were the ornithiscans. Right now, what does 178 00:10:11,640 --> 00:10:14,720 Speaker 1: that mean, Robert bird hip? Dinosaurs bird hips. So they're 179 00:10:14,760 --> 00:10:18,280 Speaker 1: sometimes classified in terms of the orientations of their hip bones. 180 00:10:18,520 --> 00:10:21,920 Speaker 1: Right now, it does not mean slender hips or slender 181 00:10:22,000 --> 00:10:25,760 Speaker 1: thighs exactly, because if you've looked as Stegosaurus, it's it's 182 00:10:25,880 --> 00:10:29,440 Speaker 1: thighs are enormous, it has these enormous hind legs. It's 183 00:10:29,480 --> 00:10:34,160 Speaker 1: a meat on the bones. Yes. Now, unlike their ornithopod 184 00:10:34,360 --> 00:10:38,600 Speaker 1: relatives such as iguanadons and the duck bill dinosaurs, uh, 185 00:10:38,920 --> 00:10:42,000 Speaker 1: they couldn't run on their hind legs. Their hind legs 186 00:10:42,000 --> 00:10:44,840 Speaker 1: were far larger than their front legs, meaning that they 187 00:10:44,960 --> 00:10:48,920 Speaker 1: these creatures actually sloped forward with their hips higher than 188 00:10:48,960 --> 00:10:52,240 Speaker 1: the rest of their bodies, kind of leaning down. Yeah. Oh, 189 00:10:52,280 --> 00:10:54,720 Speaker 1: and they also had tall spines at the base of 190 00:10:54,760 --> 00:10:58,960 Speaker 1: the tail. They probably helped anchor powerful muscles that helped 191 00:10:58,960 --> 00:11:01,480 Speaker 1: it actually lift its four legs up off the ground, 192 00:11:01,559 --> 00:11:04,400 Speaker 1: aid and feeding. So whin white couldn't run on its 193 00:11:04,600 --> 00:11:07,880 Speaker 1: hind legs. It's it could probably lift itself up and 194 00:11:08,360 --> 00:11:10,640 Speaker 1: you know, pull some branches down, that sort of thing. 195 00:11:10,840 --> 00:11:13,920 Speaker 1: And those spikes on the back of the stegosaurs tail 196 00:11:14,080 --> 00:11:17,160 Speaker 1: have a special name, right. Oh, yes, Now this is 197 00:11:17,160 --> 00:11:19,600 Speaker 1: a this is an informal name, but it is informal 198 00:11:19,679 --> 00:11:22,679 Speaker 1: even among paleontologists that they'll use it. I've read that 199 00:11:22,760 --> 00:11:28,160 Speaker 1: all paleontologists now called the spikes the phagomizer, the thagomizer. Yeah, 200 00:11:28,240 --> 00:11:30,560 Speaker 1: this is uh, this is great because this is an 201 00:11:30,600 --> 00:11:35,480 Speaker 1: ode to Gary Larson's Far Side cartoon one one in particular, 202 00:11:35,520 --> 00:11:39,959 Speaker 1: in which you had a number of caveman or Neanderthals, 203 00:11:40,000 --> 00:11:43,400 Speaker 1: you know, the typical Gary Larson Far Side caveman, always 204 00:11:43,440 --> 00:11:47,199 Speaker 1: depicting dinosaurs and uh and cave dwelling humans alongside each other. Right, 205 00:11:47,240 --> 00:11:49,880 Speaker 1: and one is giving a presentation on the hind quarters 206 00:11:49,880 --> 00:11:53,160 Speaker 1: of a Stegasaurus and he's saying, now, this end is 207 00:11:53,200 --> 00:11:58,040 Speaker 1: called the thagomizer after the late Fags Simmons, and so 208 00:11:58,520 --> 00:12:00,920 Speaker 1: now we call it the thagomizer, which feels appropriate because 209 00:12:00,960 --> 00:12:05,720 Speaker 1: it looks like uh an instrument for thagamizing something. The 210 00:12:05,720 --> 00:12:08,560 Speaker 1: word thagamizer even fits so well with our Conan motif. 211 00:12:08,600 --> 00:12:11,160 Speaker 1: You can imagine Conan saying it. Yeah. And again you 212 00:12:11,200 --> 00:12:15,120 Speaker 1: can also imagine Conan wearing some heavy armor into battle 213 00:12:15,160 --> 00:12:17,520 Speaker 1: as well, at least, you know, not so much that 214 00:12:17,559 --> 00:12:19,360 Speaker 1: he covers all of the muscles, but you know, just 215 00:12:19,600 --> 00:12:22,240 Speaker 1: to strengthen him up a little bit. Okay. And indeed, 216 00:12:22,240 --> 00:12:27,959 Speaker 1: the Stegasaurs did have these very fascinating plates on its body, right, 217 00:12:28,000 --> 00:12:31,360 Speaker 1: And there's actually some interesting debate over what role those 218 00:12:31,400 --> 00:12:34,679 Speaker 1: plates played, right, Yeah, Because when you I mean, one 219 00:12:34,679 --> 00:12:36,520 Speaker 1: of the things about the Stagasar says, you look at 220 00:12:36,559 --> 00:12:40,120 Speaker 1: it and it even even if it's an action pay 221 00:12:40,280 --> 00:12:42,000 Speaker 1: a bit of paleo art. You know, there's some sort 222 00:12:42,040 --> 00:12:44,400 Speaker 1: of a battle going on. It is hard to really 223 00:12:45,120 --> 00:12:48,640 Speaker 1: nail down what the plates are supposed to be doing, right, 224 00:12:48,720 --> 00:12:50,840 Speaker 1: I mean the easy thing to say, which you've seen 225 00:12:50,840 --> 00:12:52,920 Speaker 1: a Stagasur, it's got these plates poking up off of 226 00:12:52,920 --> 00:12:56,120 Speaker 1: its back. Um, you could say, well, of course they're 227 00:12:56,360 --> 00:12:58,480 Speaker 1: armor there for protection, and there's no way to rule 228 00:12:58,520 --> 00:13:00,920 Speaker 1: out that they might have played some role along those lines. 229 00:13:01,320 --> 00:13:04,880 Speaker 1: But also, I mean, imagine a person running into battle 230 00:13:05,280 --> 00:13:09,520 Speaker 1: with like sheets of steel sticking straight out from behind 231 00:13:09,640 --> 00:13:12,760 Speaker 1: their back. You mean generally you'd want the plates more 232 00:13:12,800 --> 00:13:17,080 Speaker 1: oriented along the surfaces of the skin to protect from attacks, right, yeah, 233 00:13:17,440 --> 00:13:19,880 Speaker 1: I mean these things were big. They were kind of 234 00:13:20,040 --> 00:13:24,880 Speaker 1: arrowhead shaped, were more than two ft or sixty centimeters high, 235 00:13:24,960 --> 00:13:26,439 Speaker 1: and and the I mean, one of the reasons for 236 00:13:26,559 --> 00:13:29,040 Speaker 1: such confusion even just about the placement of the plates 237 00:13:29,280 --> 00:13:33,240 Speaker 1: is that we have many well preserved specimens of the segasurist, 238 00:13:33,480 --> 00:13:35,480 Speaker 1: but there's never been one where the plates are still 239 00:13:35,480 --> 00:13:38,960 Speaker 1: attached to the skeleton. So there's been a lot of 240 00:13:39,000 --> 00:13:41,040 Speaker 1: discussion over how they might be arranged, so that the 241 00:13:41,120 --> 00:13:44,680 Speaker 1: vertical arrangement tends to be the one that you see, 242 00:13:44,760 --> 00:13:48,679 Speaker 1: the one that is accepted. Even then, it's uncertain if 243 00:13:48,720 --> 00:13:52,400 Speaker 1: we're looking at um two parallel rows of these or 244 00:13:52,480 --> 00:13:55,480 Speaker 1: there's a zig zagging pattern down the creature's spine. I 245 00:13:55,520 --> 00:13:58,400 Speaker 1: think the one layered zigzag is the favored today. Is 246 00:13:58,520 --> 00:14:02,200 Speaker 1: now I think out that there were paleontologists that argued 247 00:14:02,240 --> 00:14:05,080 Speaker 1: that they were actually in or on the skin more 248 00:14:05,160 --> 00:14:09,240 Speaker 1: like armor plating. But again, the popular theory now is 249 00:14:09,280 --> 00:14:11,360 Speaker 1: that there's a vertical arrangement. But if they were to 250 00:14:11,440 --> 00:14:15,360 Speaker 1: just be purely body armor, it would seem to make 251 00:14:15,400 --> 00:14:18,600 Speaker 1: more sense, at least to our our our human minds, 252 00:14:18,600 --> 00:14:21,600 Speaker 1: that they would be UH laid across its back like 253 00:14:21,840 --> 00:14:24,920 Speaker 1: plate mail, cover more of the body. Yeah, so they 254 00:14:24,920 --> 00:14:28,360 Speaker 1: were likely covered in tough horn, but some paleontogists have 255 00:14:28,400 --> 00:14:30,760 Speaker 1: theorized that you would have a layer of thin skin 256 00:14:30,880 --> 00:14:32,920 Speaker 1: that could have covered them as well, and this would 257 00:14:32,960 --> 00:14:35,200 Speaker 1: allow this would have allowed the place to serve as 258 00:14:35,240 --> 00:14:38,760 Speaker 1: heat exchangers. And then there's there are others who theorized 259 00:14:38,800 --> 00:14:41,160 Speaker 1: that it might have been brightly colored and used for 260 00:14:41,240 --> 00:14:44,960 Speaker 1: mating purposes. There's actually a cool fairly recent study to 261 00:14:45,000 --> 00:14:48,480 Speaker 1: back this up. At two thousand fifteen Princeton study argue 262 00:14:48,520 --> 00:14:54,480 Speaker 1: that stegasaurusmotsi actually featured differing male and female plate arrangements, 263 00:14:54,960 --> 00:14:57,640 Speaker 1: and this would certainly back up the mating theory and 264 00:14:57,680 --> 00:15:03,480 Speaker 1: also provide some different interpretations of UH stegasarian plating in general. UH. 265 00:15:03,520 --> 00:15:06,120 Speaker 1: They also argue that this sort of sexual dimorphism could 266 00:15:06,160 --> 00:15:09,360 Speaker 1: be widespread among non avian dinos. It means it's possible 267 00:15:09,360 --> 00:15:12,520 Speaker 1: that all three of these different theories are somehow involved. 268 00:15:12,560 --> 00:15:16,480 Speaker 1: But but one can imagine a scenario where some sort 269 00:15:16,520 --> 00:15:20,920 Speaker 1: of what was originally armor plating becomes increasingly involved in 270 00:15:21,040 --> 00:15:23,960 Speaker 1: mate selection and does just get out of control. So 271 00:15:24,000 --> 00:15:27,640 Speaker 1: they're just they're sticking up, they're they're less protective. Uh, 272 00:15:27,760 --> 00:15:31,240 Speaker 1: they're they're brightly colored. And then you know, millions and 273 00:15:31,280 --> 00:15:34,320 Speaker 1: millions of years later, a new species of super intelligent 274 00:15:34,320 --> 00:15:36,440 Speaker 1: apes just has a hard time figuring out what it 275 00:15:36,480 --> 00:15:38,760 Speaker 1: was all about. Now, when it comes to the tail 276 00:15:38,800 --> 00:15:42,240 Speaker 1: of the Stegasaurus, there's there's a lot less doubt about 277 00:15:42,240 --> 00:15:44,760 Speaker 1: what it was for. Yeah, it seems pretty clear that 278 00:15:44,800 --> 00:15:48,280 Speaker 1: it was used for defense, right, Yeah, everyone's pretty certain 279 00:15:48,320 --> 00:15:51,600 Speaker 1: that these were used just like the sort of medieval 280 00:15:51,640 --> 00:15:54,800 Speaker 1: morning star weapon that it resembles, that the stegosaurus would 281 00:15:54,800 --> 00:15:57,120 Speaker 1: have would have swung this thing around in battle to 282 00:15:57,200 --> 00:16:00,680 Speaker 1: protect itself from carnivores. And to one of the cool 283 00:16:00,720 --> 00:16:04,000 Speaker 1: things is that we actually have some fossil evidence, fossil 284 00:16:04,080 --> 00:16:08,520 Speaker 1: evidence of spike wounds on on on Alosaurus is to 285 00:16:08,560 --> 00:16:11,760 Speaker 1: back this up exactly. So the Alosaurus was a predator 286 00:16:12,800 --> 00:16:15,359 Speaker 1: that would have been around to prey on the stegosaurus, 287 00:16:15,840 --> 00:16:21,080 Speaker 1: and inteen there emerged a really awesome, fantastic example of this. 288 00:16:21,160 --> 00:16:25,720 Speaker 1: So inteen, the famous paleontologist Robert Backer, who if you'll recall, 289 00:16:25,800 --> 00:16:28,080 Speaker 1: he actually gets a name drop in Jurassic Park. You 290 00:16:28,080 --> 00:16:33,880 Speaker 1: remember that little the kid Tim who's following around Alan Grant. 291 00:16:34,080 --> 00:16:35,880 Speaker 1: He's like, I read this other book by this guy 292 00:16:35,960 --> 00:16:39,600 Speaker 1: named Backer. Yeah, that's him. Spells his name like our 293 00:16:39,640 --> 00:16:43,280 Speaker 1: Scott Baker. But h but Robert Backer. So he announced 294 00:16:43,280 --> 00:16:47,560 Speaker 1: a discovery ineen that the Geological Society of America that 295 00:16:48,040 --> 00:16:51,960 Speaker 1: the fossil remains of an Allosaurus. This predator in a 296 00:16:52,080 --> 00:16:55,920 Speaker 1: Wyoming museum showed signs of having been killed in combat, 297 00:16:56,200 --> 00:17:00,360 Speaker 1: with the stegosaurus, specifically being spiked to death in the 298 00:17:00,440 --> 00:17:04,879 Speaker 1: groin O man crosthagamized to death. There you go that. 299 00:17:05,000 --> 00:17:10,080 Speaker 1: If that's not some some con conan the barbarian behavior, 300 00:17:10,119 --> 00:17:12,199 Speaker 1: I don't know what is I know. So, what's the 301 00:17:12,240 --> 00:17:15,240 Speaker 1: evidence of this? Right? The allosaur skeleton has this deep 302 00:17:15,520 --> 00:17:20,040 Speaker 1: conical whole punctured right in its pubic bone. Can you 303 00:17:20,080 --> 00:17:22,520 Speaker 1: imagine how strong a blow would have to be to 304 00:17:22,800 --> 00:17:26,000 Speaker 1: punch a hole right through the bones of a massive 305 00:17:26,040 --> 00:17:30,280 Speaker 1: prehistoric predator. Wow? Yeah, that's some serious punch. Yeah. So 306 00:17:30,400 --> 00:17:33,720 Speaker 1: apparently this wound would have left shattered bone fragments and 307 00:17:33,760 --> 00:17:36,479 Speaker 1: all kinds of dirt and contaminants in a deep wound 308 00:17:36,600 --> 00:17:39,159 Speaker 1: like this, and then it appears what happened is the 309 00:17:39,200 --> 00:17:43,760 Speaker 1: wound got infected. So Backer says, quote a massive infection 310 00:17:44,000 --> 00:17:47,920 Speaker 1: ate away a baseball sized sector of the bone. Probably 311 00:17:47,960 --> 00:17:51,320 Speaker 1: this infection spread upwards into the soft tissue attached here, 312 00:17:51,560 --> 00:17:56,159 Speaker 1: the thigh muscles and adjacent intestines and reproductive organs, and 313 00:17:56,240 --> 00:17:59,080 Speaker 1: the wound. They are sure that it killed the allosaur 314 00:17:59,160 --> 00:18:01,920 Speaker 1: because the wound does show any signs of having healed over, 315 00:18:01,960 --> 00:18:04,080 Speaker 1: which is usually a sign that the animal died from 316 00:18:04,119 --> 00:18:07,719 Speaker 1: the wound, or maybe just coincidentally died right after receiving it. 317 00:18:07,760 --> 00:18:10,840 Speaker 1: But it probably died from this horrible wound, right. So 318 00:18:10,920 --> 00:18:14,639 Speaker 1: Bocher is talking about the specific weaponized qualities of the 319 00:18:14,680 --> 00:18:18,159 Speaker 1: thagomizer and the stegosaur's tail in general, and he says, quote, 320 00:18:18,359 --> 00:18:21,560 Speaker 1: most dinosaur tails get stiffer towards the end, but the 321 00:18:21,640 --> 00:18:25,080 Speaker 1: joints of a stegosaur tail look like a monkey's tail. 322 00:18:25,680 --> 00:18:29,360 Speaker 1: They were built for three dimensional combat. And the way 323 00:18:29,359 --> 00:18:32,199 Speaker 1: I've seen this explained was that Baker's team says, we 324 00:18:32,240 --> 00:18:35,760 Speaker 1: often think about the combat behaviors of stegosaurs as in 325 00:18:35,840 --> 00:18:37,960 Speaker 1: like they can just sort of wave their tail back 326 00:18:38,000 --> 00:18:40,120 Speaker 1: and forth like we see in cartoons, right, I mean 327 00:18:40,119 --> 00:18:42,160 Speaker 1: they probably would have been able to wave their tail 328 00:18:42,200 --> 00:18:45,080 Speaker 1: back and forth. But Baker and colleagues instead argue that 329 00:18:45,119 --> 00:18:48,120 Speaker 1: the stegosaur was not limited to this motion, but could 330 00:18:48,200 --> 00:18:52,359 Speaker 1: make these powerful stabbing thrusts with its tail like we 331 00:18:52,400 --> 00:18:55,159 Speaker 1: would with a spear or a sword. Oh I love this. 332 00:18:55,440 --> 00:18:57,760 Speaker 1: So so it's it's it's not just this idea that 333 00:18:57,800 --> 00:18:59,520 Speaker 1: it just has to wave it back and forth, and 334 00:18:59,520 --> 00:19:01,760 Speaker 1: it's just kind of a general don't approach me from 335 00:19:01,760 --> 00:19:04,600 Speaker 1: the rear because there's there are spikes back there, but 336 00:19:04,680 --> 00:19:07,520 Speaker 1: it's more of a strategic weapon that it can use 337 00:19:07,560 --> 00:19:10,280 Speaker 1: against the offender. Yeah, it's almost like a spiked arm. 338 00:19:10,520 --> 00:19:13,200 Speaker 1: Like it's got three dimensions of freedom of movement. Right, 339 00:19:13,240 --> 00:19:16,159 Speaker 1: So so if it gets uh, snuck up on by 340 00:19:16,160 --> 00:19:19,280 Speaker 1: an allosaurus. Allosaurs runs up on the stegosaur from behind 341 00:19:19,280 --> 00:19:22,399 Speaker 1: the stegosaur, it's not like has its tail pinned down. 342 00:19:22,480 --> 00:19:25,240 Speaker 1: Now it can go up and stab the allosaur and 343 00:19:25,280 --> 00:19:28,160 Speaker 1: the groin. And that's what happened here. I like how 344 00:19:28,840 --> 00:19:32,080 Speaker 1: Baker reminds us that the stegosaurus would not have kept 345 00:19:32,160 --> 00:19:36,040 Speaker 1: its thagamizer and sterile conditions. And it also kind of 346 00:19:36,040 --> 00:19:37,600 Speaker 1: makes me think, oh, what if it What if it 347 00:19:37,680 --> 00:19:39,960 Speaker 1: was quite the opposite. What if this thing was just nasty, 348 00:19:40,119 --> 00:19:43,320 Speaker 1: just it just it just dragged its thagamizer through its 349 00:19:43,320 --> 00:19:46,920 Speaker 1: own extrements. So it was just this this sharp brutal 350 00:19:47,480 --> 00:19:52,760 Speaker 1: of just feces encrusted the instrument of death, that it 351 00:19:52,760 --> 00:19:57,240 Speaker 1: would that it would weave back and forth that its enemies. Gross. Yeah, 352 00:19:57,400 --> 00:19:59,040 Speaker 1: I mean that that's great. That would have been a 353 00:19:59,080 --> 00:20:01,400 Speaker 1: really devious weapon. I don't know if you could have really, 354 00:20:01,600 --> 00:20:02,960 Speaker 1: I mean, when you think about it, could they have 355 00:20:03,040 --> 00:20:05,880 Speaker 1: had a selection pressure for that if like it wouldn't 356 00:20:05,920 --> 00:20:09,560 Speaker 1: immediately kill the allosaur that's attacking it, but would kill 357 00:20:09,600 --> 00:20:12,479 Speaker 1: it like within a few days from infection. I don't know. 358 00:20:12,680 --> 00:20:15,400 Speaker 1: I don't know. And I mean to to his actual point, though, 359 00:20:15,520 --> 00:20:19,000 Speaker 1: you would not have to have a feces encrusted thagomizer 360 00:20:19,359 --> 00:20:23,920 Speaker 1: to results in catastrophic infection exactly. No. Yeah, you'd stab 361 00:20:23,960 --> 00:20:26,280 Speaker 1: a hole through the bones, leave a bunch of fragments, 362 00:20:26,280 --> 00:20:28,760 Speaker 1: you get some dirt in there. Yeah. So, and in 363 00:20:28,800 --> 00:20:31,480 Speaker 1: any case, even if it doesn't immediately kill the allosaurus, 364 00:20:31,520 --> 00:20:33,639 Speaker 1: it's gonna wound it bad enough that the stegosaur is 365 00:20:33,640 --> 00:20:36,360 Speaker 1: probably gonna be able to get away, right. Yeah. Oh 366 00:20:36,600 --> 00:20:39,359 Speaker 1: interesting side note. If you look at older illustrations of 367 00:20:39,400 --> 00:20:43,360 Speaker 1: the stegosaurus, uh, they'll often be extra spikes on the thagomizer. 368 00:20:43,560 --> 00:20:46,280 Speaker 1: Oh yeah, Now everyone tends to agree you're looking at 369 00:20:46,320 --> 00:20:48,959 Speaker 1: four spikes, but you you see older paintings where they 370 00:20:48,960 --> 00:20:51,440 Speaker 1: have eight. Yeah, And in that paleo are you also 371 00:20:51,600 --> 00:20:54,560 Speaker 1: see the parallel arrangement of the vertical plates on the 372 00:20:54,600 --> 00:20:58,320 Speaker 1: back instead of the single line arrangement. Another side note 373 00:20:58,320 --> 00:21:01,640 Speaker 1: about this fine with the groin stab from the thagomizer, 374 00:21:02,480 --> 00:21:05,760 Speaker 1: it also affects an interesting debate over the basic survival 375 00:21:05,840 --> 00:21:09,879 Speaker 1: niche of therapod carnivores like Allosaurus. So you've got the therapods, 376 00:21:09,920 --> 00:21:14,640 Speaker 1: you know, the Tyrannosaurus type dinosaurs, the two legged walking dinosaurs, um, 377 00:21:14,800 --> 00:21:19,120 Speaker 1: these therapod predators. Some have proposed that allosaurs and tyrannosaurs 378 00:21:19,119 --> 00:21:24,080 Speaker 1: were actually scavengers primarily, rather than active hunters, and this 379 00:21:24,160 --> 00:21:28,440 Speaker 1: wound in others like it inflicted by herbivores on carnivores 380 00:21:28,640 --> 00:21:31,399 Speaker 1: seems to me to be pretty good evidence that large 381 00:21:31,440 --> 00:21:35,840 Speaker 1: therapod carnivores like Allosaurus were active hunters, right, yeah, because 382 00:21:35,920 --> 00:21:38,959 Speaker 1: why else are you gonna thagamize somebody right there? There 383 00:21:38,960 --> 00:21:42,000 Speaker 1: would be no reason for a stegosaurus to jab an 384 00:21:41,960 --> 00:21:44,639 Speaker 1: allosaurus to death unless the allosaurs was attacking it. YEA 385 00:21:44,680 --> 00:21:46,720 Speaker 1: stegosaurus is not gonna walk up and be like, stop 386 00:21:46,800 --> 00:21:52,760 Speaker 1: disrespecting the dead, yeah, because because the segasaurus doesn't doesn't 387 00:21:52,800 --> 00:21:56,960 Speaker 1: think like that, right, And speaking of thinking, the Stegasaurus 388 00:21:56,960 --> 00:22:00,920 Speaker 1: had an extremely small head, a mirror sixteen inches or 389 00:22:00,960 --> 00:22:05,199 Speaker 1: forts long. The brain, it's often pointed out, would have 390 00:22:05,240 --> 00:22:08,480 Speaker 1: been roughly the size of a walnut. I like this, 391 00:22:08,560 --> 00:22:11,240 Speaker 1: but I also like because that's an often cited fact. 392 00:22:11,560 --> 00:22:14,840 Speaker 1: The paleontologist Kenneth Carpenter, who's director of the U. S 393 00:22:14,920 --> 00:22:18,840 Speaker 1: U Eastern Prehistoric Museum in Utah, has said that despite 394 00:22:18,880 --> 00:22:23,000 Speaker 1: the despite the common comparison of the stegosaurus brain to 395 00:22:23,040 --> 00:22:26,120 Speaker 1: the walnut, he makes an even more specific comparison, which 396 00:22:26,160 --> 00:22:28,679 Speaker 1: is to say, quote, actually, it's brain had the size 397 00:22:28,720 --> 00:22:32,159 Speaker 1: and shape of a bent hot dog. I really like 398 00:22:32,240 --> 00:22:34,879 Speaker 1: this this interpretation because it kind of implies that all 399 00:22:34,920 --> 00:22:38,359 Speaker 1: the Stegasurians were we're deviance. You know, they had a 400 00:22:38,359 --> 00:22:40,560 Speaker 1: real bent hot dog of a brain. All right, I 401 00:22:40,600 --> 00:22:43,440 Speaker 1: think we should explore some facts and some controversies about 402 00:22:43,480 --> 00:22:45,760 Speaker 1: that bent hot dog when we come back from a break. 403 00:22:46,440 --> 00:22:50,320 Speaker 1: Thank thank alright, we're back. So we were talking about 404 00:22:50,359 --> 00:22:53,960 Speaker 1: the particularly low brain to body ratio that you would 405 00:22:53,960 --> 00:22:57,000 Speaker 1: have found in the stegasarians. Right, it's a it's a 406 00:22:57,080 --> 00:22:59,560 Speaker 1: crown worshiper. It's got a big weapon, that's got a 407 00:22:59,560 --> 00:23:02,600 Speaker 1: tiny head and a tiny, tiny little brain often compared 408 00:23:02,640 --> 00:23:05,280 Speaker 1: to a walnut, sort of like a bent hot dog. 409 00:23:05,320 --> 00:23:09,400 Speaker 1: In the words of one paleontologist, Why so small though, Well, ultimately, 410 00:23:10,000 --> 00:23:14,000 Speaker 1: if you're walking tank, if you're walking Jurassic tank, uh, 411 00:23:14,280 --> 00:23:16,720 Speaker 1: how much thinking do you need to do? Right? You're 412 00:23:16,760 --> 00:23:21,439 Speaker 1: you're essentially a grazing herbivore. If something attacks you, you 413 00:23:21,520 --> 00:23:26,040 Speaker 1: fight back viciously with your thagomizer, but you're not engaging 414 00:23:26,119 --> 00:23:29,639 Speaker 1: and probably a lot of rich social behavior. You're not 415 00:23:29,680 --> 00:23:32,920 Speaker 1: doing any pack hunting or anything of that nature. You're 416 00:23:32,960 --> 00:23:35,560 Speaker 1: not you don't have a like a diverse diet that 417 00:23:35,600 --> 00:23:38,080 Speaker 1: you're having to to deal with. So a lot of 418 00:23:38,080 --> 00:23:41,840 Speaker 1: the behavioral reasons that you would have a more highly 419 00:23:41,880 --> 00:23:46,879 Speaker 1: evolved uh brain are just not present in the Steaga stars. 420 00:23:47,640 --> 00:23:49,960 Speaker 1: I know some people throughout history, and will will present 421 00:23:50,000 --> 00:23:51,960 Speaker 1: counters to this in a minute. But some people throughout 422 00:23:52,000 --> 00:23:54,720 Speaker 1: history looked at the tiny brain and said, wow, that's 423 00:23:54,720 --> 00:23:57,480 Speaker 1: so small. How could it even control its body? Right? 424 00:23:57,520 --> 00:24:00,200 Speaker 1: Would that even have enough processing power to move its 425 00:24:00,200 --> 00:24:03,439 Speaker 1: body parts around? Yeah? Well, this we get into an 426 00:24:03,520 --> 00:24:08,920 Speaker 1: interesting theory that that I understand it is less popular now, 427 00:24:08,960 --> 00:24:11,320 Speaker 1: but that the idea was that, well, the stegasaurs had 428 00:24:11,359 --> 00:24:15,080 Speaker 1: a second brain in its hips to control the movements 429 00:24:15,080 --> 00:24:18,160 Speaker 1: of its hind quarters, sort of like a rear steering 430 00:24:18,160 --> 00:24:20,520 Speaker 1: wheel and a fire truck. Oh I like that. Yeah, 431 00:24:20,520 --> 00:24:23,040 Speaker 1: And now, of course nobody was arguing that this would 432 00:24:23,040 --> 00:24:25,399 Speaker 1: have been a true brain, but rather a cluster of 433 00:24:25,480 --> 00:24:30,000 Speaker 1: nervous tissue. Uh, the idea of say, neural canal in 434 00:24:30,040 --> 00:24:31,880 Speaker 1: the syncrum, and it just would have been a lot 435 00:24:32,000 --> 00:24:35,800 Speaker 1: larger in the in the stegosaurs, because the stegosaurs has 436 00:24:35,800 --> 00:24:38,320 Speaker 1: such large hind quarters. Yeah, a lot of bones, a 437 00:24:38,320 --> 00:24:40,119 Speaker 1: lot of less space between the bones, a lot of 438 00:24:40,160 --> 00:24:42,200 Speaker 1: meat on the bones, right, so there's a lot of stuff. Yeah. 439 00:24:42,240 --> 00:24:46,280 Speaker 1: So as beautiful as the stegastar butt brain idea is, 440 00:24:47,280 --> 00:24:49,080 Speaker 1: because it would be kind of beautiful to find a 441 00:24:49,119 --> 00:24:52,360 Speaker 1: creature with a brain in its butt. Unfortunately, it looks 442 00:24:52,400 --> 00:24:54,400 Speaker 1: like the evidence did not pan out for the butt 443 00:24:54,400 --> 00:24:58,040 Speaker 1: brain theory, and it's not accepted anymore. This hypothesis first 444 00:24:58,080 --> 00:25:02,040 Speaker 1: came from the nineteenth century paleon hoologist oath Neil Charles Marsh, 445 00:25:02,080 --> 00:25:04,760 Speaker 1: who wrote in eighteen eighty one that the cavity for 446 00:25:04,800 --> 00:25:07,879 Speaker 1: the expansion of the neural canal, which is what you 447 00:25:07,920 --> 00:25:12,080 Speaker 1: were just mentioning, was a quote, posterior brain case, and 448 00:25:12,119 --> 00:25:14,280 Speaker 1: that that's also a good insult to keep in your bank, 449 00:25:14,640 --> 00:25:17,679 Speaker 1: you know, posterior brain case. We're getting them all. So 450 00:25:17,720 --> 00:25:19,760 Speaker 1: it's like you call somebody a bent hot dog brain, 451 00:25:19,880 --> 00:25:24,040 Speaker 1: you call somebody a posterior brain case. But paleontologists do 452 00:25:24,080 --> 00:25:27,360 Speaker 1: not believe this anymore, mainly because there's no evidence for it, 453 00:25:27,560 --> 00:25:29,320 Speaker 1: and in fact, there's a pretty good reason for thinking 454 00:25:29,359 --> 00:25:32,320 Speaker 1: that this cavity was for something else. And I found 455 00:25:32,359 --> 00:25:35,440 Speaker 1: a good, clear explanation of this in a blog post 456 00:25:35,480 --> 00:25:38,800 Speaker 1: by a Western you paleontologist named Matt wood Dell that 457 00:25:38,920 --> 00:25:41,520 Speaker 1: clearly explains what's going on here, and funny enough, as 458 00:25:41,560 --> 00:25:45,040 Speaker 1: a side note, in the context of him mentioning this, 459 00:25:45,200 --> 00:25:48,840 Speaker 1: was complaining about being featured in a wildly inaccurate Science 460 00:25:48,920 --> 00:25:52,159 Speaker 1: Channel documentary in two thousand nine. I wonder what it was, 461 00:25:52,240 --> 00:25:55,040 Speaker 1: What is it like? Uh Stegasarian's Walk among Us. I 462 00:25:55,040 --> 00:25:57,399 Speaker 1: don't remember the name of it, but he's he's talking 463 00:25:57,440 --> 00:26:00,520 Speaker 1: about how he claims that it misleading. He cut his 464 00:26:00,560 --> 00:26:03,600 Speaker 1: interview to make it seem like he was advocating this 465 00:26:03,680 --> 00:26:07,919 Speaker 1: outdated brain butt hypothesis, and he wasn't. So instead, he 466 00:26:08,000 --> 00:26:11,199 Speaker 1: rights that there were actually two different things in the 467 00:26:11,200 --> 00:26:13,959 Speaker 1: body of a stegasur that get referred to as the 468 00:26:14,000 --> 00:26:17,720 Speaker 1: sacro lumbar expansion, this cavity you're talking about. One is 469 00:26:17,760 --> 00:26:20,320 Speaker 1: a swelling of the spinal cord around the pelvis, which 470 00:26:20,400 --> 00:26:23,560 Speaker 1: is actually present in most vertebrates and is apparently there 471 00:26:23,600 --> 00:26:27,320 Speaker 1: to control motor function. Right. One of the weird things 472 00:26:27,359 --> 00:26:29,480 Speaker 1: that a lot of people don't know is that it 473 00:26:29,920 --> 00:26:32,520 Speaker 1: is thought that much of your body's motor function, like 474 00:26:32,560 --> 00:26:36,440 Speaker 1: the less executively controlled things sort of like automatic continuous 475 00:26:36,480 --> 00:26:40,080 Speaker 1: motion like say walking just walking, some of that doesn't 476 00:26:40,119 --> 00:26:43,480 Speaker 1: come directly from the brain, but is controlled by central 477 00:26:43,840 --> 00:26:48,280 Speaker 1: locomotion function. Like there's a cluster of nervous tissue in 478 00:26:48,320 --> 00:26:51,960 Speaker 1: the spinal cord that says legs keep walking unless something 479 00:26:52,000 --> 00:26:54,800 Speaker 1: goes wrong. Now, the other thing that potentially gets called 480 00:26:54,800 --> 00:26:59,000 Speaker 1: a sacro lumbar expansion. This, this cavity is a real expansion, 481 00:26:59,040 --> 00:27:01,399 Speaker 1: a cavity in the acroll vertebrae, or is kind of 482 00:27:01,400 --> 00:27:04,439 Speaker 1: a gap in the bones back there. But it's not 483 00:27:04,560 --> 00:27:08,439 Speaker 1: unique to the Stegosaurus, and paleontologists are pretty confident that 484 00:27:08,520 --> 00:27:10,399 Speaker 1: it was not the side of a brain, but actually 485 00:27:10,400 --> 00:27:13,200 Speaker 1: the site of a glycogen body, which is a massive 486 00:27:13,320 --> 00:27:17,240 Speaker 1: glucose energy storage, which is still seen around the same 487 00:27:17,280 --> 00:27:20,680 Speaker 1: location in bird skeletons today. And of course birds are 488 00:27:20,760 --> 00:27:24,520 Speaker 1: the descendants of the dinosaurs that had them. Yeah, I 489 00:27:24,560 --> 00:27:27,399 Speaker 1: was reading about this, this theory. This was actually in 490 00:27:27,600 --> 00:27:31,280 Speaker 1: um uh In, an older dinosaur text from the nineties, 491 00:27:31,320 --> 00:27:33,640 Speaker 1: So I'm not sure to what extent this holds up, 492 00:27:33,840 --> 00:27:36,680 Speaker 1: but one possible interpretation was that this could have given 493 00:27:36,680 --> 00:27:39,240 Speaker 1: the hind quarters an energy boost when it was I 494 00:27:39,240 --> 00:27:43,399 Speaker 1: guess chlaubra in time. Oh yeah, well, uh, obviously that 495 00:27:43,520 --> 00:27:45,679 Speaker 1: is one thing to consider. I guess people don't know 496 00:27:45,760 --> 00:27:47,680 Speaker 1: for sure yet. I mean when the most recent stuff 497 00:27:47,680 --> 00:27:50,160 Speaker 1: I've read, people don't know for sure what the glycogen 498 00:27:50,200 --> 00:27:54,760 Speaker 1: body is for even in modern birds. But yeah, interesting mystery. 499 00:27:55,480 --> 00:27:59,960 Speaker 1: Another side note, if this discredited hypothesis had been true, 500 00:28:00,280 --> 00:28:03,680 Speaker 1: like if there were a second brain in the stegosaurs. 501 00:28:03,760 --> 00:28:07,280 Speaker 1: But what would the consciousness of an organism like that be, 502 00:28:07,440 --> 00:28:10,040 Speaker 1: like if if it was capable of being conscious, what 503 00:28:10,040 --> 00:28:13,880 Speaker 1: would the consciousness of an organism with two separate brains 504 00:28:13,920 --> 00:28:18,720 Speaker 1: connected by a single nervous system be Like? Huh would 505 00:28:18,720 --> 00:28:21,520 Speaker 1: it be a brain that has not two houses but three? 506 00:28:21,560 --> 00:28:24,480 Speaker 1: Would you have a tricameral mind? I don't know, No, 507 00:28:24,640 --> 00:28:27,919 Speaker 1: I mean, like, could you, I mean, imagine it for 508 00:28:27,960 --> 00:28:31,240 Speaker 1: a second. Would it be that you'd have two minds 509 00:28:31,280 --> 00:28:34,639 Speaker 1: in the same body, or would somehow one mind be 510 00:28:34,720 --> 00:28:38,400 Speaker 1: split across the two different brains connected by nervous tissue. 511 00:28:39,440 --> 00:28:43,400 Speaker 1: I guess I would tend towards the second. But I 512 00:28:43,440 --> 00:28:46,480 Speaker 1: also can't help, but but think about some of I mean, 513 00:28:46,520 --> 00:28:48,600 Speaker 1: I can't help, but think about Julian James and the 514 00:28:49,160 --> 00:28:53,560 Speaker 1: bicameral mind interpretation where you have one half speaking to 515 00:28:53,600 --> 00:28:57,280 Speaker 1: the other and uh and yeah, so I kind of 516 00:28:57,360 --> 00:29:01,120 Speaker 1: jokingly mentioned the idea of a tricameral mind, but it's 517 00:29:01,200 --> 00:29:04,160 Speaker 1: it's one help can't help. But wonder, like, how would 518 00:29:04,440 --> 00:29:09,440 Speaker 1: communication among these three regions of cognition, how would they 519 00:29:09,480 --> 00:29:14,080 Speaker 1: be experienced as conscious thought? And of course it's ridiculous. 520 00:29:14,080 --> 00:29:16,920 Speaker 1: We're talking about this with a stegasaurus, which were multiple 521 00:29:16,960 --> 00:29:22,240 Speaker 1: levels pretty far from from from from modern consciousness to 522 00:29:22,240 --> 00:29:25,800 Speaker 1: this creature. But but no, it's it's a fascinating idea. 523 00:29:26,040 --> 00:29:30,880 Speaker 1: It also makes me think of of the various models 524 00:29:30,960 --> 00:29:36,120 Speaker 1: of chakra in um in Eastern and New Age thought, 525 00:29:36,560 --> 00:29:39,040 Speaker 1: the idea that you have these different centers of cognition 526 00:29:39,400 --> 00:29:43,160 Speaker 1: throughout the body or there's one, right, Yeah, yeah, so 527 00:29:43,440 --> 00:29:45,920 Speaker 1: maybe it would sort of be like that. I mean, 528 00:29:46,000 --> 00:29:49,720 Speaker 1: I can't help but but but but someone that that 529 00:29:49,720 --> 00:29:53,760 Speaker 1: that idea when I'm trying to imagine a brain in 530 00:29:53,800 --> 00:29:57,320 Speaker 1: the butt. Okay, let's get back to the tail. Yes, yeah, 531 00:29:57,320 --> 00:29:59,280 Speaker 1: I mean, we're we're we're we're headed that way anyway, 532 00:29:59,280 --> 00:30:01,040 Speaker 1: we're talking about the the idea of a rear brain. 533 00:30:01,120 --> 00:30:02,600 Speaker 1: Let's just head on all the way back to the 534 00:30:02,640 --> 00:30:06,760 Speaker 1: thagomizer because here's a here's a fun question that I 535 00:30:06,800 --> 00:30:08,680 Speaker 1: don't I don't think i'd really thought about this before, 536 00:30:08,720 --> 00:30:12,200 Speaker 1: but it's it's a pretty natural question to ask, why 537 00:30:12,320 --> 00:30:16,959 Speaker 1: don't modern vertebrates have weaponized tails like we see with 538 00:30:17,000 --> 00:30:20,240 Speaker 1: the stegasarians or with the ankliosaurus, you know, the the 539 00:30:20,280 --> 00:30:23,720 Speaker 1: other kind of famous armored dinosaur. It's kind of a 540 00:30:23,760 --> 00:30:26,880 Speaker 1: ball tail, right, yeah, kind of like very blunt looking spikes, 541 00:30:26,960 --> 00:30:30,520 Speaker 1: but very much this enormous like dwarf and warhammer of 542 00:30:30,520 --> 00:30:33,760 Speaker 1: a tail, a little even more conan he maybe. Yeah. 543 00:30:33,840 --> 00:30:37,080 Speaker 1: And then among among among mammals, pretty stark mammals, you 544 00:30:37,120 --> 00:30:41,360 Speaker 1: had the glyphodonts, which also had a weaponized tail. So 545 00:30:41,400 --> 00:30:44,320 Speaker 1: you're saying, like, where are all the thagomizers today? Yeah? Yeah, 546 00:30:44,320 --> 00:30:47,760 Speaker 1: because you look around that our our modern verbet organisms, 547 00:30:47,800 --> 00:30:50,200 Speaker 1: and you just do not see them. So a two 548 00:30:50,240 --> 00:30:53,840 Speaker 1: thousand eighteen North Carolina State University study actually looked into 549 00:30:53,880 --> 00:30:57,400 Speaker 1: this because because they think about it, we have all 550 00:30:57,400 --> 00:31:00,200 Speaker 1: of these creatures that have horns on their head at 551 00:31:00,240 --> 00:31:03,160 Speaker 1: antlers on their head, and they're going around using these 552 00:31:03,240 --> 00:31:07,840 Speaker 1: either offensively and some sort of mating behavior against other males, 553 00:31:08,280 --> 00:31:11,640 Speaker 1: or they're using them defensively against predators. But that's up 554 00:31:11,680 --> 00:31:15,240 Speaker 1: there where the brain is exactly the most pivotal part 555 00:31:15,280 --> 00:31:18,120 Speaker 1: of the of the organism. Why are they fighting with that? 556 00:31:18,240 --> 00:31:20,000 Speaker 1: For a while now, I've been wanting to do a 557 00:31:20,040 --> 00:31:23,440 Speaker 1: whole episode on this question of weaponized heads and why 558 00:31:23,560 --> 00:31:27,640 Speaker 1: you would have so so commonly evolved weaponized heads. You're 559 00:31:27,640 --> 00:31:30,720 Speaker 1: putting the most important part of your body right out 560 00:31:30,760 --> 00:31:34,360 Speaker 1: front as a weapon. Yeah, yeah, why not use the tail? 561 00:31:35,000 --> 00:31:37,080 Speaker 1: The tail that is, you know in many organisms that 562 00:31:37,160 --> 00:31:39,720 Speaker 1: this is a part that can be lost. It's a 563 00:31:39,760 --> 00:31:44,479 Speaker 1: part that is brightly colored or or otherwise ornamented so 564 00:31:44,520 --> 00:31:47,520 Speaker 1: that it will attract the attention of predators, and not 565 00:31:47,800 --> 00:31:51,520 Speaker 1: the front end, not the business end of the organism. Yeah. So, 566 00:31:51,520 --> 00:31:54,040 Speaker 1: so what's the deal here, Well, it's indeed, it's indeed 567 00:31:54,160 --> 00:31:56,680 Speaker 1: topic we could probably go into in more depth, but 568 00:31:56,760 --> 00:31:59,840 Speaker 1: in this case, the researchers they look for commonality among 569 00:32:00,000 --> 00:32:04,680 Speaker 1: weapon tailed four legged organisms, both living in extinct, and 570 00:32:04,880 --> 00:32:07,480 Speaker 1: their guiding question was simply like, why don't turtles have 571 00:32:07,560 --> 00:32:10,240 Speaker 1: spiked tails? You know, it's a it's a they're big 572 00:32:10,320 --> 00:32:12,920 Speaker 1: armored creatures in many cases. Why is there no they 573 00:32:12,920 --> 00:32:16,120 Speaker 1: have tails? Why are there no spikes back there? Right? Well, 574 00:32:16,160 --> 00:32:20,480 Speaker 1: they determined that these are the necessary factors that you 575 00:32:20,520 --> 00:32:23,880 Speaker 1: need in place four weaponized tails to emerge. First of all, 576 00:32:23,880 --> 00:32:25,680 Speaker 1: they said, you need to be at least two hundred 577 00:32:25,680 --> 00:32:28,680 Speaker 1: pounds or a hundred krams in weight, and next, you 578 00:32:28,720 --> 00:32:32,920 Speaker 1: need to be armored and boast a thoracic stiffness enough 579 00:32:32,960 --> 00:32:36,400 Speaker 1: to swing the tail and counteract the swing force, So 580 00:32:36,480 --> 00:32:39,360 Speaker 1: no windmilling. You know, the stegasaurus is not going to 581 00:32:39,440 --> 00:32:42,040 Speaker 1: just spin in circles. It needs to be able to 582 00:32:42,080 --> 00:32:44,880 Speaker 1: move it around back and forth, or or at least 583 00:32:44,960 --> 00:32:48,080 Speaker 1: to strike and recoil. Right. You can't have like a 584 00:32:48,240 --> 00:32:51,320 Speaker 1: you know, a ten foot long arm to hit somebody with, right, 585 00:32:51,360 --> 00:32:54,320 Speaker 1: because you wouldn't be able to control it. Right. Yeah, 586 00:32:54,320 --> 00:32:57,040 Speaker 1: you need like a base of operations there. Right. And 587 00:32:57,080 --> 00:32:59,680 Speaker 1: then finally you need to be a herbivore. And the 588 00:32:59,760 --> 00:33:04,400 Speaker 1: reality is that large armored herbivores are rare, and additional 589 00:33:04,440 --> 00:33:08,160 Speaker 1: head or tail ornamentation is generally an energy expenditure beyond 590 00:33:08,280 --> 00:33:12,440 Speaker 1: what natural selection will support. Uh. So they described the 591 00:33:12,480 --> 00:33:15,800 Speaker 1: tales of beasts like the stegosaurus is being kind of 592 00:33:15,600 --> 00:33:19,640 Speaker 1: a perfect storm of traits. So which makes them all 593 00:33:19,640 --> 00:33:21,640 Speaker 1: the more special. You know that you realize in this 594 00:33:21,840 --> 00:33:29,440 Speaker 1: vast history of a varied of organisms and varied defensive forms, uh, 595 00:33:29,680 --> 00:33:34,520 Speaker 1: the stegosaurians, the glyphodonts, and Angliosaurus, they have something special 596 00:33:34,560 --> 00:33:38,960 Speaker 1: going on totally. The stegosaurs are beautiful, fascinating creatures to study. 597 00:33:39,000 --> 00:33:41,240 Speaker 1: But now that we've taken a look at them by chrom, 598 00:33:41,400 --> 00:33:43,880 Speaker 1: I think it's about time to get back into the 599 00:33:43,920 --> 00:33:47,560 Speaker 1: claim that somebody saw a living stegosaurus and carved it 600 00:33:47,560 --> 00:33:50,920 Speaker 1: into a temple in Cambodia. So let's let's go to 601 00:33:50,960 --> 00:33:53,240 Speaker 1: this claim. What's up with it? What's going on? Well, 602 00:33:53,280 --> 00:33:55,000 Speaker 1: what should we do first, Joe? Should we talk about 603 00:33:55,200 --> 00:33:58,000 Speaker 1: the carving itself or should we talk about the location 604 00:33:58,040 --> 00:33:59,800 Speaker 1: of the carving? Well, let's set the scene first and 605 00:33:59,840 --> 00:34:02,040 Speaker 1: then we'll talk about the carving. Okay, all right, Well, 606 00:34:02,240 --> 00:34:06,000 Speaker 1: the place is u is a temple complex known as 607 00:34:06,440 --> 00:34:09,960 Speaker 1: Ta prom Uh. This is the place where allegedly we 608 00:34:10,080 --> 00:34:14,320 Speaker 1: find a carving of a stegasuris. So it's a temple 609 00:34:14,400 --> 00:34:17,520 Speaker 1: in modern day Cambodia. It's a relic of the Camir 610 00:34:17,640 --> 00:34:22,520 Speaker 1: Empire and located in its then capital of Angkor. Now. 611 00:34:22,680 --> 00:34:25,680 Speaker 1: The Camera Empire lasted from a roughly the ninth to 612 00:34:25,719 --> 00:34:29,040 Speaker 1: the fifteenth century see and it ruled the entire met 613 00:34:29,080 --> 00:34:33,080 Speaker 1: Kong River valley, but then ultimately declined as empires tend 614 00:34:33,120 --> 00:34:35,960 Speaker 1: to do. And there are a number of different attributed reasons. 615 00:34:36,360 --> 00:34:39,560 Speaker 1: Uh within with as with the fall of any empire. Um, 616 00:34:39,600 --> 00:34:43,520 Speaker 1: it's a complex thing, but historians and anthropologists can't help 617 00:34:43,520 --> 00:34:48,480 Speaker 1: but tease various possibilities apart. Right, So one idea is 618 00:34:48,520 --> 00:34:51,640 Speaker 1: that you know, you simply had Thai conquests going on 619 00:34:52,200 --> 00:34:56,440 Speaker 1: that that whittled them down. Or one idea that's particularly 620 00:34:56,480 --> 00:35:00,920 Speaker 1: engaging is the idea that widespread religious conversion, uh, kind 621 00:35:00,960 --> 00:35:03,759 Speaker 1: of destabilized things to some extent. Oh, do you know 622 00:35:03,920 --> 00:35:06,200 Speaker 1: what the conversion from what to what would have been? 623 00:35:06,239 --> 00:35:09,560 Speaker 1: It would have been Hinduism to Buddhism, particularly to uh 624 00:35:09,920 --> 00:35:14,520 Speaker 1: Theravada Buddhism for instance. One idea here is that under Hinduism, 625 00:35:14,760 --> 00:35:18,920 Speaker 1: the rulers of the Communite empire were divine kings or 626 00:35:19,040 --> 00:35:23,000 Speaker 1: dave A raja, but with a conversion to theraved to Buddhism, 627 00:35:23,040 --> 00:35:26,480 Speaker 1: they became more mortal. But ultimately there are a lot 628 00:35:26,520 --> 00:35:29,160 Speaker 1: of factors to consider here. Yeah, that can undercut your 629 00:35:29,160 --> 00:35:31,439 Speaker 1: divine right Huh. Yeah, it takes me back a little 630 00:35:31,440 --> 00:35:35,000 Speaker 1: to our our episode on the divine rule of kings 631 00:35:35,080 --> 00:35:39,160 Speaker 1: and what happens when when they've outlived their usefulness. Yeah, 632 00:35:39,239 --> 00:35:42,839 Speaker 1: ritual regicide, yeah yeah, But ultimately there are a number 633 00:35:42,880 --> 00:35:46,440 Speaker 1: of factors to consider here, including like maritime trade. I 634 00:35:46,480 --> 00:35:49,080 Speaker 1: saw that come up in h in some papers, including 635 00:35:49,080 --> 00:35:53,920 Speaker 1: a paper by anthropologist Miriam T. Stark, who also points 636 00:35:53,920 --> 00:35:57,920 Speaker 1: out that Cambodia's ancient histories among the least known of 637 00:35:57,920 --> 00:36:00,640 Speaker 1: of Southeast Asia. And this is due to a number 638 00:36:00,680 --> 00:36:04,520 Speaker 1: of factors, including civil war and just an increasingly like 639 00:36:04,640 --> 00:36:08,759 Speaker 1: colonial tradition of of attempting to understand the history of 640 00:36:08,800 --> 00:36:11,680 Speaker 1: another people. But as comparatively little as we might know 641 00:36:11,719 --> 00:36:14,520 Speaker 1: about it, they certainly did leave behind some amazing and 642 00:36:14,600 --> 00:36:17,920 Speaker 1: beautiful relics of the civilization. Oh yeah, without doubt, Now 643 00:36:17,920 --> 00:36:21,040 Speaker 1: I have I've never been to Cambodia, but but I have. 644 00:36:21,200 --> 00:36:23,719 Speaker 1: But but I want to because i've I've certainly I've 645 00:36:23,760 --> 00:36:27,160 Speaker 1: seen images and I've heard about the famous temp temple 646 00:36:27,200 --> 00:36:31,359 Speaker 1: complex of angkor Watt. You've probably seen pictures of Oh yeah, yeah, 647 00:36:31,360 --> 00:36:34,840 Speaker 1: these these are beautiful to behold. Uh. It's the nation's 648 00:36:34,880 --> 00:36:38,360 Speaker 1: most popular tourist destination. It's a UNESCO World Heritage Site, 649 00:36:38,600 --> 00:36:42,200 Speaker 1: as is Ta Prom. Now these uh, these temple complexes, 650 00:36:42,239 --> 00:36:44,600 Speaker 1: they would have been Hindo to Hindu temples originally, and 651 00:36:44,600 --> 00:36:48,400 Speaker 1: they gradually became more Buddhist and function as this massive 652 00:36:48,440 --> 00:36:52,440 Speaker 1: conversion took place within the Commi Empire when was to 653 00:36:52,640 --> 00:36:55,160 Speaker 1: prom built, So this would have been built in eleven 654 00:36:55,239 --> 00:37:01,200 Speaker 1: eighty six by King Jayavarman the seventh and sadly, I 655 00:37:01,200 --> 00:37:03,680 Speaker 1: have to say it's also known today as the tomb 656 00:37:03,760 --> 00:37:07,160 Speaker 1: Raider Temple. It was used as a location for the 657 00:37:07,200 --> 00:37:10,200 Speaker 1: two thousand one film tomb Raider. The two thousand one film, 658 00:37:10,360 --> 00:37:15,080 Speaker 1: which one is that the original Angelia original Angelina Jolie 659 00:37:15,160 --> 00:37:17,839 Speaker 1: saw it in the theater, don't remember anything about it. 660 00:37:17,960 --> 00:37:20,560 Speaker 1: I looked back at the the IMDb list for it 661 00:37:20,480 --> 00:37:23,400 Speaker 1: and it has like a like a number of famous 662 00:37:23,640 --> 00:37:27,560 Speaker 1: actors in it. John Void in it? Is that, right? God? 663 00:37:27,719 --> 00:37:29,959 Speaker 1: Was he? I don't know. I don't know about John Void, 664 00:37:30,080 --> 00:37:33,000 Speaker 1: but because he's I mean he's Angela, you know, Angelina 665 00:37:33,080 --> 00:37:37,360 Speaker 1: Jolie's father, so maybe he was in it. But Daniel 666 00:37:37,360 --> 00:37:40,239 Speaker 1: Craig was in it, I believe pre James Bond. Oh. 667 00:37:40,280 --> 00:37:41,759 Speaker 1: I just looked it up. You know who it has 668 00:37:41,800 --> 00:37:44,040 Speaker 1: in it? It's got Ian Glenn, the guy who plays 669 00:37:44,080 --> 00:37:46,880 Speaker 1: Jora Mormont on Game of Thrones. Oh, yeah, and it 670 00:37:47,000 --> 00:37:50,440 Speaker 1: I believe it also has uh, what's his name, Noah Taylor? 671 00:37:50,640 --> 00:37:52,960 Speaker 1: Noah Taylor? Yes, He was another actor who was on 672 00:37:53,000 --> 00:37:54,759 Speaker 1: Game of Thrones and has been in a number of 673 00:37:54,760 --> 00:37:58,480 Speaker 1: other interesting films over the years. And it all goes 674 00:37:58,480 --> 00:38:01,440 Speaker 1: back to tomb Rater. Thank you to m writer. All right, 675 00:38:01,520 --> 00:38:03,759 Speaker 1: let's not turn this into tomb Rater to blow your mind. 676 00:38:04,040 --> 00:38:07,439 Speaker 1: So the temple, Yes, yes, So I found a nice 677 00:38:07,560 --> 00:38:10,279 Speaker 1: ride up on Lonely Planet about the top Rom. I 678 00:38:10,320 --> 00:38:12,520 Speaker 1: just want to read one paragraph from it that it 679 00:38:12,840 --> 00:38:16,040 Speaker 1: nicely sets the stage. Quote. Top Rom is a temple 680 00:38:16,080 --> 00:38:19,840 Speaker 1: of towers, closed courtyards, and narrow corridors. Many of the 681 00:38:19,840 --> 00:38:24,240 Speaker 1: corridors are impassable, clogged with jumbled piles of delicately carved 682 00:38:24,239 --> 00:38:27,960 Speaker 1: stone blocks, dislodged by the roots of long decayed trees. 683 00:38:28,600 --> 00:38:32,120 Speaker 1: Bass reliefs on bulging walls are carpeted with lichen moss, 684 00:38:32,160 --> 00:38:35,400 Speaker 1: and creeping plants and shrubs sprout from the roofs of 685 00:38:35,520 --> 00:38:40,600 Speaker 1: monumental porches. Trees hundreds of years old tower overhead, their leaves, 686 00:38:40,640 --> 00:38:43,960 Speaker 1: filtering the sunlight and casting a greenish pall over the 687 00:38:43,960 --> 00:38:47,319 Speaker 1: whole scene. Well, that's beautifully described. Yeah, it makes me 688 00:38:47,360 --> 00:38:50,160 Speaker 1: want to go there, But I'm also I'm susceptible to 689 00:38:50,239 --> 00:38:53,200 Speaker 1: this kind of setting anyway, and I think a lot 690 00:38:53,280 --> 00:38:55,680 Speaker 1: of people are right, Like it keeps showing up in 691 00:38:55,719 --> 00:38:58,920 Speaker 1: our adventure movies and video games and all that. I 692 00:38:58,960 --> 00:39:03,120 Speaker 1: wonder why we so love the image of the overgrown 693 00:39:03,239 --> 00:39:07,440 Speaker 1: jungle temple with crumbling ancient stone archways being consumed by 694 00:39:07,480 --> 00:39:11,879 Speaker 1: tree roots and vines. It's it's a singularly beautiful kind 695 00:39:11,920 --> 00:39:15,279 Speaker 1: of image and setting for some reason. Well, I can't 696 00:39:15,320 --> 00:39:17,040 Speaker 1: help but think there are a number of different things 697 00:39:17,040 --> 00:39:21,480 Speaker 1: going on, So the more pessimistic side of me tends 698 00:39:21,520 --> 00:39:22,960 Speaker 1: to think with it. Part of it is kind of 699 00:39:22,960 --> 00:39:29,600 Speaker 1: like a colonial um like pulp saturated notion of the 700 00:39:29,880 --> 00:39:33,560 Speaker 1: like the noble westerner walking among the ruins of fallen 701 00:39:33,600 --> 00:39:37,160 Speaker 1: ancient cultures. Well, you could maybe see something like that, 702 00:39:37,200 --> 00:39:39,560 Speaker 1: But I think it's equally true of ruins no matter 703 00:39:39,600 --> 00:39:42,279 Speaker 1: what culture they're from, right, And you can imagine it's 704 00:39:42,320 --> 00:39:45,960 Speaker 1: equally true of old cathedral ruins in Western Europe, yeah, 705 00:39:46,080 --> 00:39:48,960 Speaker 1: or just old supermarket ruins here in the States. Like 706 00:39:49,200 --> 00:39:51,719 Speaker 1: anywhere I go that I see some sort of ruins, 707 00:39:52,239 --> 00:39:55,480 Speaker 1: you know, be they ancient or fairly recent, They're fascinating. 708 00:39:55,480 --> 00:39:58,400 Speaker 1: I want to walk inside them and see what's there 709 00:39:58,440 --> 00:40:02,759 Speaker 1: and or what's living inside. It's specifically the idea of 710 00:40:02,840 --> 00:40:08,480 Speaker 1: the plant overgrowth of like a sacred stone building. You 711 00:40:08,520 --> 00:40:11,280 Speaker 1: know that that's like the main elements that are featuring 712 00:40:11,360 --> 00:40:14,520 Speaker 1: in in my picture of this in the mind. I 713 00:40:14,560 --> 00:40:16,880 Speaker 1: guess maybe it's just something about like maybe maybe it 714 00:40:16,960 --> 00:40:19,920 Speaker 1: indicates the folly of human projects. I don't know. Yeah, well, 715 00:40:19,960 --> 00:40:22,960 Speaker 1: there is kind of like a memento more aspect to it, right, 716 00:40:23,040 --> 00:40:25,800 Speaker 1: this this sort of ozamandi as effect that no matter 717 00:40:25,800 --> 00:40:29,720 Speaker 1: how great the structure, it is going to fall with time, 718 00:40:30,280 --> 00:40:33,560 Speaker 1: nature is going to going going to flow over it 719 00:40:33,640 --> 00:40:36,600 Speaker 1: and take it back. Uh. And there's something like beautiful 720 00:40:36,600 --> 00:40:39,680 Speaker 1: and haunting and poignant about all of that. It's like 721 00:40:39,800 --> 00:40:43,760 Speaker 1: watching human built structure has become a part of the forest. Yeah. 722 00:40:43,840 --> 00:40:48,040 Speaker 1: But then also, I mean we're I am fascinated by 723 00:40:48,320 --> 00:40:51,440 Speaker 1: by other cultures, and many of them are ancient cultures. 724 00:40:51,640 --> 00:40:53,719 Speaker 1: And therefore to visit a site like this or even 725 00:40:53,760 --> 00:40:56,239 Speaker 1: just look at photographs of it, it's kind of like 726 00:40:56,320 --> 00:40:59,200 Speaker 1: going back in time. But how far back in time? 727 00:41:00,000 --> 00:41:02,080 Speaker 1: It's a good question. Okay, Well, there's not really a 728 00:41:02,160 --> 00:41:05,080 Speaker 1: question about when the temple is from. It seems you know, 729 00:41:05,160 --> 00:41:07,719 Speaker 1: it's less than a thousand years old, right, right, So 730 00:41:07,880 --> 00:41:10,480 Speaker 1: it's being less than a thousand years old. I think 731 00:41:10,480 --> 00:41:13,640 Speaker 1: it's about eight hundred years older. So what is the 732 00:41:13,800 --> 00:41:18,800 Speaker 1: argument that someone has carved a stegosaurus into the temple 733 00:41:18,880 --> 00:41:22,040 Speaker 1: as a decorative motif. And I'll remind everybody here that 734 00:41:22,120 --> 00:41:25,120 Speaker 1: you can see the image we're talking about at Stuff 735 00:41:25,120 --> 00:41:27,000 Speaker 1: to Blow your Mind dot Com on the landing page 736 00:41:27,000 --> 00:41:29,360 Speaker 1: for this episode. It's going to be the central image 737 00:41:29,840 --> 00:41:34,520 Speaker 1: for the episode, the carving of the supposed Stegasaurus. Right, 738 00:41:34,560 --> 00:41:37,120 Speaker 1: so there's a building, it's got a pillar, was sort 739 00:41:37,160 --> 00:41:39,600 Speaker 1: of like a pillar against a wall, and there are 740 00:41:39,640 --> 00:41:42,279 Speaker 1: carvings all up and down the vertical length of the 741 00:41:42,320 --> 00:41:46,760 Speaker 1: pillar where they're sort of like these these abstract lines 742 00:41:46,880 --> 00:41:51,440 Speaker 1: snaking around framing obviously representative carvings that are supposed to 743 00:41:51,520 --> 00:41:55,400 Speaker 1: be animals and mythological beasts. Yes, and one of these, 744 00:41:55,520 --> 00:41:58,280 Speaker 1: when you look at it, it's kind of it's inside 745 00:41:58,320 --> 00:42:03,040 Speaker 1: of a circle, or at least a curved decorative flourish here, 746 00:42:03,400 --> 00:42:06,560 Speaker 1: and it appears to be a quadruped. It has a 747 00:42:06,600 --> 00:42:10,800 Speaker 1: long tail, and it has one, two, three, four, five, 748 00:42:11,200 --> 00:42:15,200 Speaker 1: five or six I think maybe six perhaps bony plates 749 00:42:15,200 --> 00:42:19,040 Speaker 1: on its back. It kind of looks like a stegasarian, 750 00:42:19,600 --> 00:42:22,080 Speaker 1: and you could even go as far to say that, yeah, 751 00:42:22,160 --> 00:42:24,360 Speaker 1: it looks like it could be one of the I 752 00:42:24,400 --> 00:42:29,160 Speaker 1: think three varieties of stegasarians that have been found in 753 00:42:29,440 --> 00:42:32,680 Speaker 1: modern China. So you know, you don't even have to say, well, 754 00:42:32,680 --> 00:42:34,879 Speaker 1: how did they get over from North America? While there 755 00:42:34,880 --> 00:42:39,840 Speaker 1: were there are fossil remains of stegasarians from uh, generally 756 00:42:39,880 --> 00:42:42,040 Speaker 1: that part of Asia. So I would also add that 757 00:42:42,080 --> 00:42:43,920 Speaker 1: it feels a bit silly to attempt to match up 758 00:42:43,920 --> 00:42:47,440 Speaker 1: a supposed dinosaur that would have evolved from these forms 759 00:42:47,440 --> 00:42:50,000 Speaker 1: across a hundred and fifty million years or so. But 760 00:42:50,000 --> 00:42:52,359 Speaker 1: but still we have to You have to admit, when 761 00:42:52,360 --> 00:42:54,879 Speaker 1: you look at it, you can say, well, that kind 762 00:42:54,880 --> 00:42:57,600 Speaker 1: of looks like a Stegasaurus. I don't buy it for 763 00:42:57,600 --> 00:42:59,920 Speaker 1: a second, but I have to admit that looking at 764 00:43:00,040 --> 00:43:04,840 Speaker 1: it and imagining it as a stegosaurus is kind of intriguing. 765 00:43:05,560 --> 00:43:08,080 Speaker 1: So I was trying to understand the argument that this 766 00:43:08,239 --> 00:43:12,000 Speaker 1: is a stegosaurus. I found an article on a creationist 767 00:43:12,040 --> 00:43:15,320 Speaker 1: website called Answers in Genesis is that you got. You 768 00:43:15,400 --> 00:43:17,280 Speaker 1: gotta keep an eye out for this one, because actually, 769 00:43:17,280 --> 00:43:22,040 Speaker 1: when you start googling like evolutionary science topics. Somehow, this 770 00:43:22,120 --> 00:43:24,640 Speaker 1: website very often tends to make it near the top 771 00:43:24,680 --> 00:43:27,480 Speaker 1: of Google results, like it'll pop up your maybe you're 772 00:43:27,520 --> 00:43:31,160 Speaker 1: searching should I mouthwash before I brushed my teeth afterwards? 773 00:43:31,680 --> 00:43:33,880 Speaker 1: And then answers you're you're getting answer like, oh, it's 774 00:43:33,880 --> 00:43:36,200 Speaker 1: answers in genesis. Maybe I shouldn't trust this. Yeah, they've 775 00:43:36,200 --> 00:43:38,480 Speaker 1: got some good s c O game going whatever it is, 776 00:43:38,520 --> 00:43:41,439 Speaker 1: so they get up in those Google results. But uh, yeah, 777 00:43:41,560 --> 00:43:44,480 Speaker 1: this is a Young Earth creationist website that is going 778 00:43:44,520 --> 00:43:48,160 Speaker 1: to pedal a whole lot of pseudoscience about geology and paleontology. 779 00:43:48,520 --> 00:43:50,719 Speaker 1: And they've got an article attributed to a writer named 780 00:43:50,800 --> 00:43:54,400 Speaker 1: Kenneth Cole empd uh that is defending the idea that 781 00:43:54,480 --> 00:43:57,840 Speaker 1: this is evidence of a young Earth, like a recent 782 00:43:57,960 --> 00:44:00,640 Speaker 1: creation and humans and dinosaurs living at the same time. 783 00:44:01,280 --> 00:44:04,680 Speaker 1: So Coal Rights quote. There are no mythological figures among 784 00:44:04,719 --> 00:44:08,120 Speaker 1: the roundels, so one can reasonably conclude that these figures 785 00:44:08,120 --> 00:44:10,920 Speaker 1: depict the animals that were commonly seen by the ancient 786 00:44:11,000 --> 00:44:14,279 Speaker 1: Khmer people in the twelfth century. That means that only 787 00:44:14,320 --> 00:44:17,040 Speaker 1: a little over eight hundred years ago, some dinosaurs were 788 00:44:17,080 --> 00:44:20,680 Speaker 1: likely still living in that region of Cambodia. Of course, 789 00:44:20,840 --> 00:44:23,799 Speaker 1: this is no surprise to biblical creationists, because we know 790 00:44:23,920 --> 00:44:26,880 Speaker 1: from Genesis One that land animals such as dinosaurs and 791 00:44:26,960 --> 00:44:30,440 Speaker 1: humans were living together in the beginning, and that representatives 792 00:44:30,440 --> 00:44:33,040 Speaker 1: of the land animals e g. Dinosaurs were saved on 793 00:44:33,080 --> 00:44:35,919 Speaker 1: the arc to repopulate the Earth after the flood only 794 00:44:35,960 --> 00:44:38,920 Speaker 1: four thousand, three hundred years ago. No, I don't want 795 00:44:38,960 --> 00:44:42,600 Speaker 1: to give in to excessive, unnecessary mockery, but I think 796 00:44:42,680 --> 00:44:46,040 Speaker 1: this is not a tenable position, and we can explore 797 00:44:46,080 --> 00:44:47,960 Speaker 1: some of the reasons for that when we come back 798 00:44:48,000 --> 00:44:52,560 Speaker 1: from a break. All right, we're back. So, Joe, you 799 00:44:52,640 --> 00:44:55,480 Speaker 1: just read this, this passage from this Young Earth creationists 800 00:44:55,680 --> 00:45:01,160 Speaker 1: about Noah Noah's ark and uh the stegasarians ward the vessel. Yeah. 801 00:45:01,280 --> 00:45:04,960 Speaker 1: I would say that this actually represents one way you 802 00:45:05,000 --> 00:45:07,120 Speaker 1: could take if you're going to go with the line 803 00:45:07,200 --> 00:45:10,600 Speaker 1: that this carving in this Cambodian temple is actually a 804 00:45:10,640 --> 00:45:12,600 Speaker 1: depiction of a stegosaurus. There are a couple of ways 805 00:45:12,640 --> 00:45:14,520 Speaker 1: you could go with it, but you've got to start 806 00:45:14,560 --> 00:45:17,040 Speaker 1: with the idea that there's an obvious problem here. The 807 00:45:17,120 --> 00:45:20,120 Speaker 1: carving is less than a thousand years old. We mentioned 808 00:45:20,120 --> 00:45:23,560 Speaker 1: earlier that all non avian dinosaurs went extinct sixty six 809 00:45:23,600 --> 00:45:26,839 Speaker 1: million years ago or before that. Well, for the Stegosaurus, 810 00:45:26,920 --> 00:45:29,520 Speaker 1: the problem is even worse because it's one of those 811 00:45:29,560 --> 00:45:34,040 Speaker 1: that went extinct long before the KPg extinction event took place. 812 00:45:34,640 --> 00:45:38,760 Speaker 1: The Stegosaurus genus apparently went extinct during the Late Jurassic period, 813 00:45:38,880 --> 00:45:42,200 Speaker 1: roughly a hundred and fifty million years ago, and by 814 00:45:42,200 --> 00:45:45,680 Speaker 1: the time of the KPg extinction, Stegosaurus had already been 815 00:45:45,680 --> 00:45:49,160 Speaker 1: extinct for almost a hundred million years. So a way 816 00:45:49,160 --> 00:45:51,800 Speaker 1: of putting this I've seen quoted before is that more 817 00:45:51,840 --> 00:45:56,440 Speaker 1: time separates the Stegosaurus from the Tyrannosaurus rex than separates 818 00:45:56,480 --> 00:46:00,400 Speaker 1: the Tyrannosaurus rex from us. So we're talking just a 819 00:46:00,680 --> 00:46:03,520 Speaker 1: vast lengths of time that are that are that are 820 00:46:03,600 --> 00:46:07,719 Speaker 1: almost incomprehensible for us neager humans right now. If you 821 00:46:07,719 --> 00:46:09,799 Speaker 1: want to say, it wasn't a Stegosaurus, but it was 822 00:46:09,920 --> 00:46:14,400 Speaker 1: a related stegasaurian, right, some other type of related or 823 00:46:14,520 --> 00:46:17,279 Speaker 1: aiski and herb before with with plates on its back 824 00:46:17,320 --> 00:46:20,279 Speaker 1: of some kind from the group Stegasauria that may have 825 00:46:20,320 --> 00:46:23,439 Speaker 1: existed a little bit later, maybe into the earlier maybe 826 00:46:23,480 --> 00:46:26,680 Speaker 1: Middle Cretaceous, but even those probably didn't make it to 827 00:46:26,680 --> 00:46:29,839 Speaker 1: the KPg event, which in any case wiped out all 828 00:46:29,880 --> 00:46:33,720 Speaker 1: of the dinosaurs except the ones that became modern day birds. 829 00:46:33,760 --> 00:46:36,040 Speaker 1: So if you want to believe that it really is 830 00:46:36,200 --> 00:46:40,560 Speaker 1: a live Stegasaurus that somebody saw being depicted in the carving, uh, 831 00:46:40,840 --> 00:46:43,800 Speaker 1: and that the carving is original, of course there's another 832 00:46:43,840 --> 00:46:45,560 Speaker 1: idea that, of course, well, what if it's a more 833 00:46:45,600 --> 00:46:48,720 Speaker 1: recent hoax or something. Then I think there are really 834 00:46:48,760 --> 00:46:51,759 Speaker 1: two main ways people could go. You could either say 835 00:46:51,920 --> 00:46:55,240 Speaker 1: some stegosaurs managed to survive about a hundred and fifty 836 00:46:55,280 --> 00:46:58,480 Speaker 1: million million years longer than we thought without leaving any 837 00:46:58,520 --> 00:47:01,120 Speaker 1: fossil evidence in the mean time, and we can call 838 00:47:01,200 --> 00:47:04,799 Speaker 1: the believers of this hypothesis the cryptid camp. Right, This 839 00:47:04,880 --> 00:47:08,000 Speaker 1: is the standard cryptozoology kind of thing. There's some isolated 840 00:47:08,040 --> 00:47:11,920 Speaker 1: population of an otherwise unknown creature, right, Yeah, that we 841 00:47:11,960 --> 00:47:15,200 Speaker 1: don't we we haven't explored every nook and cranny of 842 00:47:15,239 --> 00:47:17,520 Speaker 1: the Earth, and it's in those nooks and crannies that 843 00:47:17,560 --> 00:47:24,279 Speaker 1: we might find uh, fabulous or henceforth unrecognized species. The 844 00:47:24,320 --> 00:47:26,759 Speaker 1: other one is what we heard from Kenneth Cole m d. 845 00:47:26,960 --> 00:47:30,040 Speaker 1: Which is the entire timeline of Earth history is wrong. 846 00:47:30,400 --> 00:47:32,839 Speaker 1: The Earth is actually less than ten thousand years old, 847 00:47:32,840 --> 00:47:37,200 Speaker 1: and dinosaurs existed alongside most of human civilization throughout history. 848 00:47:37,520 --> 00:47:40,160 Speaker 1: We can call this the young Earth creationist camp. And 849 00:47:40,200 --> 00:47:42,640 Speaker 1: I have theological problems with that because I think God 850 00:47:42,680 --> 00:47:45,440 Speaker 1: would have destroyed all the crooked, hot dog brained dinosaurs 851 00:47:45,880 --> 00:47:47,759 Speaker 1: with the flood, and then they would not have been 852 00:47:48,320 --> 00:47:51,360 Speaker 1: permitted to board the arc. But that's that's that's my attantion. 853 00:47:51,680 --> 00:47:54,680 Speaker 1: Leave your theology aside, Robert, I won't hear of it. 854 00:47:55,600 --> 00:47:58,440 Speaker 1: Uh So, I think we can say probably neither of 855 00:47:58,480 --> 00:48:02,440 Speaker 1: these is plausible at all. But the creationist the hypothesis 856 00:48:02,480 --> 00:48:07,040 Speaker 1: actually has more problems going for it than the cryptid hypothesis. Yeah, 857 00:48:07,040 --> 00:48:10,560 Speaker 1: the cryptid hypothesis at least does not require us to 858 00:48:10,680 --> 00:48:13,879 Speaker 1: bend and break time. Yeah, before we get into those 859 00:48:13,920 --> 00:48:16,600 Speaker 1: I would say, we don't really need to debate the 860 00:48:16,719 --> 00:48:19,800 Speaker 1: visual qualities of the image, because even if it looked 861 00:48:19,880 --> 00:48:23,360 Speaker 1: exactly like a stegosaurus, this would not be a reason 862 00:48:23,400 --> 00:48:26,280 Speaker 1: to think that humans and dinosaurs existed at the same time. 863 00:48:26,800 --> 00:48:30,400 Speaker 1: But I must point out it does not look exactly 864 00:48:30,480 --> 00:48:32,879 Speaker 1: like a stegosaurus. I mean, if you look at it, 865 00:48:33,239 --> 00:48:36,040 Speaker 1: you might say, oh, that's a stegosaurus. Because you'd recognize 866 00:48:36,080 --> 00:48:39,839 Speaker 1: the plates, right, Stegosaurus had a very small cranium with 867 00:48:39,920 --> 00:48:42,680 Speaker 1: no known adornments, and this creature in the carving has 868 00:48:42,680 --> 00:48:45,000 Speaker 1: a huge head with the appearance of some kind of 869 00:48:45,040 --> 00:48:47,920 Speaker 1: pointed ear or horn on its face. I don't know 870 00:48:48,000 --> 00:48:50,359 Speaker 1: exactly what it's supposed to be, but there's a thing 871 00:48:50,440 --> 00:48:53,799 Speaker 1: on the face and the head is very large. Stegosaurus 872 00:48:53,800 --> 00:48:56,720 Speaker 1: also has a huge tail with spikes, and this carving 873 00:48:56,800 --> 00:48:59,840 Speaker 1: has a pretty small tail with no spikes. So to 874 00:49:00,120 --> 00:49:02,880 Speaker 1: clear what I'm saying is that nothing about it looks 875 00:49:02,920 --> 00:49:05,799 Speaker 1: like a Stegasaurus except that it has four legs and 876 00:49:05,840 --> 00:49:08,960 Speaker 1: appears to have these lumps positioned over its back. And 877 00:49:08,960 --> 00:49:12,080 Speaker 1: these lumps, by the way, might not even be parts 878 00:49:12,239 --> 00:49:15,560 Speaker 1: of the animal. They there's a strong argument that these 879 00:49:15,560 --> 00:49:18,839 Speaker 1: are perhaps supposed to be leaves or some other vegetative 880 00:49:19,080 --> 00:49:21,560 Speaker 1: detail in the background. Oh yeah, that's true. I mean, 881 00:49:21,560 --> 00:49:23,520 Speaker 1: if you look at some of the same carvings from 882 00:49:23,560 --> 00:49:26,640 Speaker 1: this area of the temple, other animals are depicted with 883 00:49:26,760 --> 00:49:29,319 Speaker 1: sort of like shapes in the background that I think 884 00:49:29,360 --> 00:49:32,200 Speaker 1: are just sort of like supposed to be background foliage 885 00:49:32,280 --> 00:49:34,920 Speaker 1: or something. Now, it's just another problem that I have 886 00:49:35,080 --> 00:49:39,680 Speaker 1: with it. Either the stegosaurus or some stegasarian creature were 887 00:49:39,760 --> 00:49:44,520 Speaker 1: to have survived to the point where humans either solid 888 00:49:44,640 --> 00:49:46,960 Speaker 1: or just remembered it. They just had like an oral 889 00:49:47,040 --> 00:49:49,680 Speaker 1: history of the stegasarians, and it made their way made 890 00:49:49,680 --> 00:49:52,279 Speaker 1: their made its way into their art. Why would this 891 00:49:52,360 --> 00:49:55,239 Speaker 1: be the lone example of it? Oh? Why would there 892 00:49:55,239 --> 00:49:59,719 Speaker 1: not be stegasarians everywhere right where all the other ones exactly? 893 00:49:59,760 --> 00:50:02,920 Speaker 1: And and also, if you're gonna look at fantastic creatures 894 00:50:02,920 --> 00:50:05,720 Speaker 1: in art from that region, then what about the naga, 895 00:50:05,800 --> 00:50:09,719 Speaker 1: the seven headed serpent that you see in various Southeast 896 00:50:09,800 --> 00:50:13,280 Speaker 1: Asian traditions, right, I mean, so you're saying, like, why, 897 00:50:13,400 --> 00:50:15,600 Speaker 1: why don't we assume that maybe that's based on a 898 00:50:15,600 --> 00:50:18,440 Speaker 1: real animal they saw too. Yeah, I think you're they're 899 00:50:18,440 --> 00:50:23,040 Speaker 1: really cherry picking a particular beast or fantastic beast and 900 00:50:23,080 --> 00:50:25,919 Speaker 1: then saying it is real when they're if you're gonna 901 00:50:25,960 --> 00:50:27,759 Speaker 1: let that one through the gates, then you have to 902 00:50:27,840 --> 00:50:30,720 Speaker 1: let the Naga. You have to let every fantastic creature 903 00:50:31,239 --> 00:50:35,520 Speaker 1: from from Hindu and Buddhist traditions in through the gates 904 00:50:35,600 --> 00:50:38,560 Speaker 1: as well. It's only fair let them on the art too. Well, 905 00:50:38,560 --> 00:50:40,680 Speaker 1: that's a good point. I think a supporter could say 906 00:50:40,800 --> 00:50:45,040 Speaker 1: the it's a Stegasaurus argument. Uh, well, it's got going 907 00:50:45,080 --> 00:50:47,760 Speaker 1: for it that the Stegosaurus did exist at some point, 908 00:50:48,120 --> 00:50:50,640 Speaker 1: and we don't have evidence that the Naga ever existed. 909 00:50:50,880 --> 00:50:53,400 Speaker 1: But we don't have evidence that the Naga ever existed 910 00:50:53,440 --> 00:50:56,239 Speaker 1: because what nobody's ever said they saw one, and there's 911 00:50:56,239 --> 00:50:59,680 Speaker 1: no fossil evidence. With the Stegosaurus, nobody's ever said that 912 00:50:59,719 --> 00:51:02,160 Speaker 1: they seen one in any kind of credible way, and 913 00:51:02,400 --> 00:51:05,640 Speaker 1: there's no fossil evidence since a hundred and fifty million 914 00:51:05,719 --> 00:51:08,120 Speaker 1: years ago or whenever the particular genus you're talking about 915 00:51:08,120 --> 00:51:11,000 Speaker 1: when extinct, so within the period of the past dozens 916 00:51:11,000 --> 00:51:13,799 Speaker 1: of millions of years. Actually, the evidential issue is the 917 00:51:13,880 --> 00:51:18,359 Speaker 1: same for the Nauga and the Stegosaurus. Meanwhile, uh, there 918 00:51:18,440 --> 00:51:21,600 Speaker 1: there's we have no doubt that there were sightings of 919 00:51:21,600 --> 00:51:25,279 Speaker 1: of course bores. Uh. And the job and Rhino, which 920 00:51:25,680 --> 00:51:28,200 Speaker 1: we discussed in depth in our Rhino Horn episode. The 921 00:51:28,280 --> 00:51:31,000 Speaker 1: job and Rhino is is at least if you're used 922 00:51:31,040 --> 00:51:33,640 Speaker 1: to just seeing the African varieties of rhino, it is 923 00:51:33,640 --> 00:51:36,759 Speaker 1: a weird looking rhino and it it looks a lot 924 00:51:36,840 --> 00:51:39,720 Speaker 1: like the creature in this carving. Well, yeah, the creature 925 00:51:39,719 --> 00:51:42,200 Speaker 1: in the carving. It's got something strange going on in 926 00:51:42,239 --> 00:51:44,160 Speaker 1: its face that looks like it could be an ear 927 00:51:44,320 --> 00:51:47,400 Speaker 1: or a horn or something. Uh, and I'm inclined to 928 00:51:47,400 --> 00:51:50,400 Speaker 1: think that, Yeah, that could be some kind of rhino horn. Yeah. 929 00:51:50,440 --> 00:51:53,000 Speaker 1: So in these again, our real beasts, it's just it's 930 00:51:53,040 --> 00:51:56,239 Speaker 1: just they're far fewer leaps and bounds one has to 931 00:51:56,280 --> 00:51:58,440 Speaker 1: make in logic to get there. And even if you 932 00:51:58,480 --> 00:52:00,520 Speaker 1: were too ignoral the stuff we're saying, this would only 933 00:52:00,560 --> 00:52:03,320 Speaker 1: go to support the cryptid argument that somehow this small 934 00:52:03,360 --> 00:52:07,880 Speaker 1: population of stegasaur Is or related stegosaurids managed to survive 935 00:52:08,000 --> 00:52:10,560 Speaker 1: undetected until at least eight hundred years ago or so, 936 00:52:10,960 --> 00:52:14,319 Speaker 1: leaving no other traces that we've ever found. If I'm 937 00:52:14,320 --> 00:52:18,360 Speaker 1: being generous, the crypted argument seems at best physically possible, 938 00:52:18,400 --> 00:52:21,359 Speaker 1: but just really implausible, Like, I don't see any good 939 00:52:21,400 --> 00:52:25,560 Speaker 1: reason to prefer it over a handful of rival explanations 940 00:52:25,560 --> 00:52:28,040 Speaker 1: you can come up with, which include, for example, the 941 00:52:28,120 --> 00:52:30,320 Speaker 1: carving is supposed to be a bore or a rhino 942 00:52:30,440 --> 00:52:32,960 Speaker 1: like we've been talking about. Maybe the carving is a 943 00:52:33,000 --> 00:52:37,160 Speaker 1: mythological beast of the imagination that has a superficial resemblance 944 00:52:37,200 --> 00:52:40,000 Speaker 1: to something with back plates. And if you just look 945 00:52:40,040 --> 00:52:42,000 Speaker 1: on the pillar in the temple, if you look just 946 00:52:42,040 --> 00:52:45,520 Speaker 1: like two spaces down, there's another crazy looking mythological beast 947 00:52:45,600 --> 00:52:48,080 Speaker 1: that's pretty cool, and it's got all kinds of features 948 00:52:48,080 --> 00:52:50,640 Speaker 1: that you don't see in nature. Yeah, this looks like 949 00:52:50,680 --> 00:52:54,160 Speaker 1: some sort of like a cross between the lorax and 950 00:52:54,200 --> 00:52:57,720 Speaker 1: the and and and the monsters from where the wild 951 00:52:57,719 --> 00:53:00,479 Speaker 1: things are. Well, it's sort of it sort of looks like, yeah, 952 00:53:00,520 --> 00:53:04,520 Speaker 1: it's like a fawn, but it's wearing like a magistrate's wig. 953 00:53:05,280 --> 00:53:07,480 Speaker 1: And nobody's making the argument that this was a real 954 00:53:07,560 --> 00:53:10,840 Speaker 1: creature that I have seen. No, but give them time. 955 00:53:11,719 --> 00:53:14,719 Speaker 1: Uh So, another possibility, I I don't know that there's 956 00:53:14,719 --> 00:53:16,960 Speaker 1: any evidence to support this, but then again, it's probably 957 00:53:17,000 --> 00:53:19,760 Speaker 1: more plausible than a crypted thing, is that the carving 958 00:53:19,840 --> 00:53:22,440 Speaker 1: is a more recent forgery. I'm not advocating that, but 959 00:53:22,560 --> 00:53:25,880 Speaker 1: of course it's possible. Yeah, I think I did see. It. 960 00:53:25,920 --> 00:53:28,080 Speaker 1: Brought up the idea that, oh, what if a film 961 00:53:28,120 --> 00:53:30,719 Speaker 1: crew did it. Western film crew comes in and maybe 962 00:53:30,719 --> 00:53:34,840 Speaker 1: they fake a stegasaurus on ancient ruins, which which seems 963 00:53:34,880 --> 00:53:37,640 Speaker 1: like that would be an extreme and a reckless thing 964 00:53:37,719 --> 00:53:39,799 Speaker 1: for anyone to do so. I don't know how much 965 00:53:40,680 --> 00:53:44,320 Speaker 1: how much credence I give to that idea. Personally, I 966 00:53:44,560 --> 00:53:46,600 Speaker 1: don't see any evidence for it at all, except to 967 00:53:46,640 --> 00:53:48,480 Speaker 1: say that it would be a less extravagant thing to 968 00:53:48,520 --> 00:53:51,680 Speaker 1: resort to than saying that Stegasaurus has survived an extra 969 00:53:51,760 --> 00:53:55,200 Speaker 1: hundred million years or and we we haven't even mentioned 970 00:53:55,200 --> 00:53:58,640 Speaker 1: this yet geo mythology. Like if you haven't heard our 971 00:53:58,760 --> 00:54:01,800 Speaker 1: episode the Mystery of the myth Fleshed Fossil, We discussed 972 00:54:01,800 --> 00:54:04,960 Speaker 1: the work of the Stanford historian Adrian Mayer, who has 973 00:54:04,960 --> 00:54:09,120 Speaker 1: written books documenting many possible cases where ancient art, mythology, 974 00:54:09,239 --> 00:54:12,640 Speaker 1: folk beliefs could have been inspired by ancient people's coming 975 00:54:12,640 --> 00:54:16,680 Speaker 1: across confusing geo facts like fossils of dinosaurs and other 976 00:54:16,760 --> 00:54:20,239 Speaker 1: amazing extinct animals. So you find a dinosaur fossil, you're 977 00:54:20,239 --> 00:54:22,680 Speaker 1: in the ancient world. It looks like nothing you've ever 978 00:54:22,719 --> 00:54:25,800 Speaker 1: seen alive today. So maybe it's some sort of monster. 979 00:54:25,960 --> 00:54:29,280 Speaker 1: It's a griffin, it's a dragon, it's cyclops and so forth, 980 00:54:29,719 --> 00:54:33,319 Speaker 1: and so some ancient stegasaurians, not the Stegosaurus itself, but 981 00:54:33,480 --> 00:54:37,239 Speaker 1: related backplated orna. This key and herbivores did live in 982 00:54:37,280 --> 00:54:40,080 Speaker 1: this area around China, as you've pointed out, at least 983 00:54:40,080 --> 00:54:44,120 Speaker 1: three different stegasaurians, so there's no way to rule out 984 00:54:44,160 --> 00:54:46,440 Speaker 1: that this kind of carving could also have been inspired 985 00:54:46,440 --> 00:54:50,680 Speaker 1: by somebody finding a mysterious stegasaurian fossil skeleton with backplates, 986 00:54:51,160 --> 00:54:54,360 Speaker 1: passing that morphology on through art and folklore, and it 987 00:54:54,560 --> 00:54:58,520 Speaker 1: ending up getting carved into a temple wall. Yeah. I mean, 988 00:54:58,640 --> 00:55:01,200 Speaker 1: especially if you're digging up lot of stone to build 989 00:55:01,239 --> 00:55:04,759 Speaker 1: a giant temple complex. Yeah. Now we don't know which 990 00:55:04,800 --> 00:55:06,800 Speaker 1: which of these is correct, but any of them seem 991 00:55:06,880 --> 00:55:10,600 Speaker 1: more plausible than huge land dwelling dinosaurs surviving millions of 992 00:55:10,680 --> 00:55:13,560 Speaker 1: years after we have any fossil records of them, So 993 00:55:13,640 --> 00:55:17,720 Speaker 1: I think the cryptid approach kind of falls apart. Yes. Plus, 994 00:55:17,800 --> 00:55:20,640 Speaker 1: I have to think that if dinosaurs were around during 995 00:55:20,800 --> 00:55:23,759 Speaker 1: the Roman Empire, they would have wound up in the Colosseum. 996 00:55:23,880 --> 00:55:26,520 Speaker 1: There would have been there would have been a Stegasaurus 997 00:55:27,200 --> 00:55:30,560 Speaker 1: in the Colosseum battling a gladiator. Well, I mean, yeah, 998 00:55:30,600 --> 00:55:32,520 Speaker 1: I mean you go back into the age of emperors 999 00:55:32,560 --> 00:55:34,680 Speaker 1: and kings and all that. I mean, they really did 1000 00:55:34,760 --> 00:55:37,560 Speaker 1: love to get some exotic animals into their into their 1001 00:55:37,600 --> 00:55:40,759 Speaker 1: menagerie and and trot them around for people to see. Right, 1002 00:55:41,000 --> 00:55:44,000 Speaker 1: they're countless tales. We could we could do a whole 1003 00:55:44,040 --> 00:55:48,880 Speaker 1: episode on examples of exotic creatures that were transported across 1004 00:55:48,920 --> 00:55:53,319 Speaker 1: continents so that royal individuals could look at them and 1005 00:55:53,360 --> 00:55:56,200 Speaker 1: you know, maybe have them fight another beast. Now, that's 1006 00:55:56,239 --> 00:55:59,479 Speaker 1: all the cryptid approach, I think. Unfortunately, the argument gets 1007 00:55:59,480 --> 00:56:01,520 Speaker 1: a lot worse if you try to take the young 1008 00:56:01,560 --> 00:56:05,719 Speaker 1: Earth approach, because the idea that the humans saw stegosaurs, 1009 00:56:05,760 --> 00:56:09,840 Speaker 1: because dinosaurs actually existed alongside humans for much of history, 1010 00:56:09,880 --> 00:56:12,800 Speaker 1: and that history is less than ten thousand years long. 1011 00:56:14,160 --> 00:56:16,560 Speaker 1: I have to say, I, I you know, sometimes I 1012 00:56:16,560 --> 00:56:19,160 Speaker 1: think people in the skeptic community have too much fun 1013 00:56:19,280 --> 00:56:22,360 Speaker 1: harping on the wrongness of stuff like that. Like it 1014 00:56:22,440 --> 00:56:25,400 Speaker 1: can Yeah, there are lots of people who have deeply 1015 00:56:25,520 --> 00:56:28,359 Speaker 1: untenable views like the idea of a young Earth, but 1016 00:56:28,440 --> 00:56:32,279 Speaker 1: it can feel excessive and unnecessary to just like keep 1017 00:56:32,320 --> 00:56:34,680 Speaker 1: harping on how wrong that is. But at the same time, 1018 00:56:35,080 --> 00:56:37,120 Speaker 1: I do feel a kind of sadness about all of 1019 00:56:37,160 --> 00:56:40,920 Speaker 1: the energy that goes into defending views like that, because 1020 00:56:41,239 --> 00:56:43,320 Speaker 1: it's similar to like the energy that would go into 1021 00:56:43,400 --> 00:56:46,880 Speaker 1: defending a flat earth approach. It's something that is not 1022 00:56:47,000 --> 00:56:50,920 Speaker 1: just disagreeing with the majority of scientists about a fact 1023 00:56:50,960 --> 00:56:53,640 Speaker 1: here or a fact there, but it's sort of undermining 1024 00:56:53,680 --> 00:56:57,359 Speaker 1: the integrity of the entire scientific enterprise. If you take 1025 00:56:57,400 --> 00:57:01,040 Speaker 1: a position like flat Earth or like younger, you are 1026 00:57:01,320 --> 00:57:06,279 Speaker 1: forced by extension to essentially deny everything. Yeah, I mean, 1027 00:57:06,440 --> 00:57:08,759 Speaker 1: one way that I think about it is I I 1028 00:57:08,800 --> 00:57:12,600 Speaker 1: will sadly never see a living stegasaurus. But at the 1029 00:57:12,640 --> 00:57:16,480 Speaker 1: same time, the stegosaurus was real, and that is that 1030 00:57:16,640 --> 00:57:19,760 Speaker 1: is fascinating and it's amazing, and it it fills me 1031 00:57:19,840 --> 00:57:23,560 Speaker 1: with with wonder and awe to to to to research 1032 00:57:23,640 --> 00:57:26,320 Speaker 1: the creature and read about it and see these artistic 1033 00:57:26,360 --> 00:57:30,240 Speaker 1: depictions of it. Likewise, I will never see a unicorn, 1034 00:57:30,800 --> 00:57:35,000 Speaker 1: and unicorns never existed, and yet the unicorn images of 1035 00:57:35,000 --> 00:57:37,760 Speaker 1: the unicorn are beautiful. And when you start reading about 1036 00:57:37,800 --> 00:57:41,240 Speaker 1: the complex the symbolism of the unicorn, that that is 1037 00:57:41,280 --> 00:57:44,160 Speaker 1: beautiful and it can bring meaning to your life. And uh, 1038 00:57:44,600 --> 00:57:48,800 Speaker 1: it's it's no, there's no need to start bending your 1039 00:57:48,840 --> 00:57:52,200 Speaker 1: reality and bending your your understanding of the world so 1040 00:57:52,240 --> 00:57:55,520 Speaker 1: that you can make it somehow more real than it 1041 00:57:55,600 --> 00:57:58,240 Speaker 1: is as if the idea of it and the potency 1042 00:57:58,240 --> 00:58:00,560 Speaker 1: of the idea is not real it exactly. I mean, 1043 00:58:00,720 --> 00:58:04,440 Speaker 1: is is it really worth believing in the physical existence 1044 00:58:04,480 --> 00:58:09,520 Speaker 1: of a unicorn to make you essentially forced to undermine 1045 00:58:09,560 --> 00:58:17,360 Speaker 1: the foundations of astronomy, cosmology, astrophysics, geology, radiochemistry, biology, paleontology, genetics. 1046 00:58:17,600 --> 00:58:22,040 Speaker 1: I mean, all of these fields are are based on 1047 00:58:22,360 --> 00:58:28,560 Speaker 1: predictions and consistently produce results that are in agreement basically 1048 00:58:28,640 --> 00:58:31,720 Speaker 1: with with a picture of an old Earth and an 1049 00:58:31,720 --> 00:58:34,240 Speaker 1: old universe. And all of these fields not only have 1050 00:58:34,360 --> 00:58:38,240 Speaker 1: successful predictive theories corroborating the old Universe, the old Earth, 1051 00:58:38,320 --> 00:58:41,320 Speaker 1: hundreds of millions of years of animal evolution, but they 1052 00:58:41,320 --> 00:58:45,600 Speaker 1: independently produce new results and overturn old misconceptions that keep 1053 00:58:45,720 --> 00:58:49,320 Speaker 1: further resolving the clarity of that picture rather than undermining it. 1054 00:58:49,800 --> 00:58:51,400 Speaker 1: And of course, you know, as we all know, some 1055 00:58:51,440 --> 00:58:53,560 Speaker 1: of these fields use that picture of the world to 1056 00:58:53,600 --> 00:58:57,680 Speaker 1: produce technologies that even Cambodian stegosaur advocates use in their 1057 00:58:57,760 --> 00:59:00,919 Speaker 1: daily lives end up just having to do so much 1058 00:59:01,600 --> 00:59:04,120 Speaker 1: mental gymnastics to make it work. And you know who 1059 00:59:04,120 --> 00:59:08,920 Speaker 1: didn't have time for mental gymnastics Stegasaurus. The stegosaurus was 1060 00:59:08,920 --> 00:59:11,760 Speaker 1: a plain dealer. Yeah yeah, if it's grain, eat it. 1061 00:59:11,800 --> 00:59:13,800 Speaker 1: If it tries to bite you, stab it in the 1062 00:59:13,800 --> 00:59:19,960 Speaker 1: groin with sagony. Is it good by crom Al? Right? Well, 1063 00:59:19,960 --> 00:59:22,680 Speaker 1: there you there you go. Hopefully this episode A a 1064 00:59:22,680 --> 00:59:24,760 Speaker 1: Minute provided us an excuse to just talk about the 1065 00:59:24,800 --> 00:59:28,440 Speaker 1: Stegasaurus for quite a while, and we got to discuss 1066 00:59:28,640 --> 00:59:32,720 Speaker 1: some of these other issues related to crypto zoology, a 1067 00:59:33,200 --> 00:59:36,320 Speaker 1: Young Earth, creationism and um and just a little bit 1068 00:59:36,320 --> 00:59:40,400 Speaker 1: of Cambodian history. Again. You can find the key images 1069 00:59:40,440 --> 00:59:42,440 Speaker 1: that we're talking about here at stuff to Blow your 1070 00:59:42,440 --> 00:59:45,680 Speaker 1: Mind dot com.
