00:00:01,920 --> 00:00:06,880
Speaker 1: Welcome to brain Stuff production of iHeart Radio. Hey brain Stuff.

2
00:00:06,880 --> 00:00:09,559
Speaker 1: I'm Lauren voc Obaum and this is another classic episode

3
00:00:09,600 --> 00:00:13,040
Speaker 1: from our previous host, Christian Sagar. This one talks about

4
00:00:13,080 --> 00:00:18,000
Speaker 1: perhaps the smallest of the completely wild prehistoric creatures, the

5
00:00:18,120 --> 00:00:24,200
Speaker 1: hell ant. Hey brain Stuff is Christian Sagar. Here, fire ants,

6
00:00:24,360 --> 00:00:27,480
Speaker 1: carpenter ants, bull ants. There are a lot of ant

7
00:00:27,520 --> 00:00:31,280
Speaker 1: species that can cause a great deal of harm. The

8
00:00:31,400 --> 00:00:34,960
Speaker 1: worst one alive today, according to the Guinness World Records,

9
00:00:35,360 --> 00:00:39,760
Speaker 1: is the bulldog aunt. It has killed at least three humans,

10
00:00:39,840 --> 00:00:44,600
Speaker 1: some within fifteen minutes. But perhaps the worst aunt ever

11
00:00:45,200 --> 00:00:49,279
Speaker 1: was the hell aunt, a prehistoric insect that was recently

12
00:00:49,320 --> 00:00:53,199
Speaker 1: discovered incased in a chunk of Myanmar amber dating to

13
00:00:53,280 --> 00:00:58,160
Speaker 1: the Late Cretaceous period. Evolutionary biologist Philip Barden of the

14
00:00:58,200 --> 00:01:02,440
Speaker 1: New Jersey Institute of Technology and his team wrote about

15
00:01:02,480 --> 00:01:07,399
Speaker 1: the hell aunt discovery in the journal Systemic Entomology. The

16
00:01:07,440 --> 00:01:10,399
Speaker 1: hell aunt got its name from its anatomy and behavior.

17
00:01:10,760 --> 00:01:14,040
Speaker 1: Instead of having a typical mouth, the hell aunt had

18
00:01:14,120 --> 00:01:18,880
Speaker 1: blades that stuck upward, think like tusks, plus a horn

19
00:01:19,160 --> 00:01:23,000
Speaker 1: that was reinforced with metal. Scientists don't know for sure

20
00:01:23,080 --> 00:01:26,840
Speaker 1: how the hell aunt used its unusual appendages, but they

21
00:01:26,880 --> 00:01:30,280
Speaker 1: have some theories. First, it seems clear that the ant's

22
00:01:30,360 --> 00:01:34,400
Speaker 1: tusks and horn were mainly used for catching prey, So

23
00:01:34,440 --> 00:01:37,679
Speaker 1: here's one possible m O. When it came to finding dinner.

24
00:01:38,040 --> 00:01:41,720
Speaker 1: When a tasty insect passed nearby, the hell ance jaw

25
00:01:41,760 --> 00:01:45,040
Speaker 1: tusks would flip the insect up and onto its horn,

26
00:01:45,319 --> 00:01:49,040
Speaker 1: impaling it. Spearing prey does take a toll, though, which

27
00:01:49,080 --> 00:01:52,600
Speaker 1: is probably why the hell ants horn was clad with metal.

28
00:01:53,080 --> 00:01:56,600
Speaker 1: And if that isn't gruesome enough, researchers say this prehistoric

29
00:01:56,680 --> 00:02:00,600
Speaker 1: insect might have had some vampire like tendencies to When

30
00:02:00,600 --> 00:02:04,160
Speaker 1: the ants snagged its prey, its tusk like jaws clothes

31
00:02:04,320 --> 00:02:07,680
Speaker 1: to form a gutter, which may have been a means

32
00:02:07,720 --> 00:02:12,720
Speaker 1: of funneling the insects blood right down into the ant's gullet.

33
00:02:13,200 --> 00:02:17,480
Speaker 1: The hell ants, scientifically known as Lingua mirmes vlady, was

34
00:02:17,560 --> 00:02:21,160
Speaker 1: discovered in a chunk of amber that was nine million

35
00:02:21,280 --> 00:02:25,520
Speaker 1: years old. Although it's unusual appendages were likely used to

36
00:02:25,560 --> 00:02:29,680
Speaker 1: catch its food, researchers say they may have occasionally been

37
00:02:29,800 --> 00:02:34,320
Speaker 1: used defensively. This is not the only insects sporting metal, either.

38
00:02:34,800 --> 00:02:39,400
Speaker 1: Some present day termite species actually have zinc and manganese

39
00:02:39,520 --> 00:02:45,120
Speaker 1: in their mandibles. However, there are no modern ants similarly equipped.
