They're both members 00:00:40.980,00:00:42.620 of the Therepod sub order, but the pervatasaurus is smaller 00:00:43.790,00:00:46.390 and much, much creepier. - Now, how did you and your team 00:00:46.490,00:00:49.730 make this monumental discovery. - Oh, well, the skeleton was discovered 00:00:50.030,00:00:52.730 in a dank, subterranean cave far away from any of the other 00:00:53.030,00:00:54.700 dinosaur fossils we excavated. 00:00:55.000,00:00:57.470 The large number of well preserved footprints suggests 00:00:57.810,00:00:59.310 the pervatasaurus spent the majority of its time 00:00:59.410,00:01:01.710 there in the cave, just pacing back and forth alone. 00:01:02.010,00:01:04.780 So, it was basically a solitary creature. - Oh, for the most part, yes. 00:01:05.150,00:01:07.240 The pervatasaurus seemed to only approach other dinosaurs 00:01:07.450,00:01:08.860 when they were in large groups, 00:01:09.190,00:01:11.700 which allowed the pervatasaurus to stealthily creep between their bodies 00:01:11.990,00:01:14.030 and rub himself up against them. - It's incredible. 00:01:14.130,00:01:17.730 All of my research indicates that it really liked mud and slick surfaces 00:01:17.830,00:01:20.270 and would often submerge half of its body in mud, 00:01:20.600,00:01:22.900 while groping its own genitals and mumbling to itself. 00:01:23.220,00:01:25.440 Now, it was long thought, it was my understanding at least, 00:01:25.740,00:01:29.040 that the pervatasaurus was a carnivore. - Oh that was a misconception. 00:01:29.350,00:01:32.250 By studying the pervatasaurus fossilized feces, 00:01:32.350,00:01:35.250 which we found neatly stacked in symmetrical piles in the cave, 00:01:35.350,00:01:37.750 we discovered that the pervatasaurus was in fact a herbivore. 00:01:38.080,00:01:39.420 So it was a scavenger of sorts then. - Oh yes. 00:01:39.730,00:01:42.370 We have discovered drag marks near several caves 00:01:42.460,00:01:45.130 indicating the pervatasaurus likely lured smaller dinosaurs 00:01:45.230,00:01:48.540 back to its cave, but the lack of skeletons suggest the pervatasaurus 00:01:48.850,00:01:51.970 didn't kill and eat them, but only watched them as it masturbated. 00:01:52.070,00:01:54.510 Well, it's remarkable. Thanks for being with us, Dr. Vaughn. 00:01:54.810,00:01:56.650 Congratulations on your find. - Thank you. 00:01:56.750,00:02:00.150 Moving on, accusations of steroid use are calling into question the legitimacy 00:02:00.250,00:02:02.290 of many of the world's greatest sports' bloopers. 00:02:04.320,00:02:08.260 Still Ahead This Hour: Marlboro Charity Sponsors 0.3K Charity Walk
