0:00:00.000,0:00:06.940 Captions by www.SubPLY.com . . . . . . . . . . . . . 0:00:06.940,0:00:09.680 The scientific community is buzzing following the announcement that 0:00:09.680,0:00:13.750 archaeologists in Argentina have uncovered the first complete skeleton 0:00:13.750,0:00:15.850 of the world's oldest sexual predator. 0:00:15.850,0:00:19.260 According to the team of archaeologists, the discovery of a full skeleton 0:00:19.260,0:00:22.830 of Pervatasaurus Leroy, the first dinosaur species 0:00:22.830,0:00:24.600 known to stalk another not for food, 0:00:24.600,0:00:28.240 but for sexual satisfaction could, quote: "...shed light on any number 0:00:28.240,0:00:30.370 of mysteries surrounding this ancient lecherous creature." 0:00:30.370,0:00:33.980 Joining us now from Argentina is the lead paleontologist on the dig, 0:00:33.980,0:00:35.480 Andrew Vaughn. - Hello. 0:00:35.480,0:00:38.820 Dr. Vaughn, the pervatasaurus looks a bit like the Tyrannosaurus Rex. 0:00:38.820,0:00:40.980 Are the two related? - Yes. They're both members 0:00:40.980,0:00:43.790 of the Therepod sub order, but the pervatasaurus is smaller 0:00:43.790,0:00:46.490 and much, much creepier. - Now, how did you and your team 0:00:46.490,0:00:50.030 make this monumental discovery. - Oh, well, the skeleton was discovered 0:00:50.030,0:00:53.030 in a dank, subterranean cave far away from any of the other 0:00:53.030,0:00:55.000 dinosaur fossils we excavated. 0:00:55.000,0:00:57.810 The large number of well preserved footprints suggests 0:00:57.810,0:00:59.410 the pervatasaurus spent the majority of its time 0:00:59.410,0:01:02.010 there in the cave, just pacing back and forth alone. 0:01:02.010,0:01:05.150 So, it was basically a solitary creature. - Oh, for the most part, yes. 0:01:05.150,0:01:07.450 The pervatasaurus seemed to only approach other dinosaurs 0:01:07.450,0:01:09.190 when they were in large groups, 0:01:09.190,0:01:11.990 which allowed the pervatasaurus to stealthily creep between their bodies 0:01:11.990,0:01:14.130 and rub himself up against them. - It's incredible. 0:01:14.130,0:01:17.830 All of my research indicates that it really liked mud and slick surfaces 0:01:17.830,0:01:20.600 and would often submerge half of its body in mud, 0:01:20.600,0:01:23.220 while groping its own genitals and mumbling to itself. 0:01:23.220,0:01:25.740 Now, it was long thought, it was my understanding at least, 0:01:25.740,0:01:29.350 that the pervatasaurus was a carnivore. - Oh that was a misconception. 0:01:29.350,0:01:32.350 By studying the pervatasaurus fossilized feces, 0:01:32.350,0:01:35.350 which we found neatly stacked in symmetrical piles in the cave, 0:01:35.350,0:01:38.080 we discovered that the pervatasaurus was in fact an herbivore. 0:01:38.080,0:01:39.730 So it was a scavenger of sorts then. - Oh yes. 0:01:39.730,0:01:42.460 We have discovered drag marks near several caves 0:01:42.460,0:01:45.230 indicating the pervatasaurus likely lured smaller dinosaurs 0:01:45.230,0:01:48.850 back to its cave, but the lack of skeletons suggests the pervatasaurus 0:01:48.850,0:01:52.070 didn't kill and eat them, but only watched them as it masturbated. 0:01:52.070,0:01:54.810 Well, it's remarkable. Thanks for being with us, Dr. Vaughn. 0:01:54.810,0:01:56.750 Congratulations on your find. - Thank you. 0:01:56.750,0:02:00.250 Moving on, accusations of steroid use are calling into question the legitimacy 0:02:00.250,0:02:04.320 of many of the world's greatest sports' bloopers. 0:02:04.320,9:59:59.000 Still Ahead This Hour: Marlboro Charity Sponsors 0.3K Charity Walk
