They're both members 14 00:00:40,980 --> 00:00:43,790 of the Therepod sub order, but the pervatasaurus is smaller 15 00:00:43,790 --> 00:00:46,490 and much, much creepier. - Now, how did you and your team 16 00:00:46,490 --> 00:00:50,030 make this monumental discovery. - Oh, well, the skeleton was discovered 17 00:00:50,030 --> 00:00:53,030 in a dank, subterranean cave far away from any of the other 18 00:00:53,030 --> 00:00:55,000 dinosaur fossils we excavated. 19 00:00:55,000 --> 00:00:57,810 The large number of well preserved footprints suggests 20 00:00:57,810 --> 00:00:59,410 the pervatasaurus spent the majority of its time 21 00:00:59,410 --> 00:01:02,010 there in the cave, just pacing back and forth alone. 22 00:01:02,010 --> 00:01:05,150 So, it was basically a solitary creature. - Oh, for the most part, yes. 23 00:01:05,150 --> 00:01:07,450 The pervatasaurus seemed to only approach other dinosaurs 24 00:01:07,450 --> 00:01:09,190 when they were in large groups, 25 00:01:09,190 --> 00:01:11,990 which allowed the pervatasaurus to stealthily creep between their bodies 26 00:01:11,990 --> 00:01:14,130 and rub himself up against them. - It's incredible. 27 00:01:14,130 --> 00:01:17,830 All of my research indicates that it really liked mud and slick surfaces 28 00:01:17,830 --> 00:01:20,600 and would often submerge half of its body in mud, 29 00:01:20,600 --> 00:01:23,220 while groping its own genitals and mumbling to itself. 30 00:01:23,220 --> 00:01:25,740 Now, it was long thought, it was my understanding at least, 31 00:01:25,740 --> 00:01:29,350 that the pervatasaurus was a carnivore. - Oh that was a misconception. 32 00:01:29,350 --> 00:01:32,350 By studying the pervatasaurus fossilized feces, 33 00:01:32,350 --> 00:01:35,350 which we found neatly stacked in symmetrical piles in the cave, 34 00:01:35,350 --> 00:01:38,080 we discovered that the pervatasaurus was in fact an herbivore. 35 00:01:38,080 --> 00:01:39,730 So it was a scavenger of sorts then. - Oh yes. 36 00:01:39,730 --> 00:01:42,460 We have discovered drag marks near several caves 37 00:01:42,460 --> 00:01:45,230 indicating the pervatasaurus likely lured smaller dinosaurs 38 00:01:45,230 --> 00:01:48,850 back to its cave, but the lack of skeletons suggests the pervatasaurus 39 00:01:48,850 --> 00:01:52,070 didn't kill and eat them, but only watched them as it masturbated. 40 00:01:52,070 --> 00:01:54,810 Well, it's remarkable.
