E3 - Gang Killers

Aired: August 12, 2008

In south central Montana, a group of bird-like predators called Deinonychus are unearthed, altering our view of dinosaurs forever. Scientists are quick to recognize that these creatures, equipped with a deeply recurved sickle-shaped claw, do not fit into the image of a slow-moving, cold-blooded dinosaur. Lying next to the skeletons of these raptors were the remains of a large plant-eating dinosaur called Tenontosaurus. Modern CAT Scanners help scientists get a never-before-seen look into how these animals moved, fought and behaved. Watch as experts recreate what happened when a pack of deadly raptors took on an adversary more than twice their own size.

Discover a prehistoric watering hole where multiple dinosaur species fought to the death under the intense heat of a Jurassic drought. Watch as more than 15,000 bones are uncovered at the scene of one of the bloodiest battles in Paleohistory. Scientists are able to identify Allosaurus and its rival Ceratosaurus as the predators. Evidence collected at the site, detailed animal behaviors, and the results of hi-tech CAT scanning are used to recreate what happened on this dry lakebed in Utah 150 million years ago.

E5 - Ice Aged Monsters

The remains of two of the largest predatory mammals of North America are discovered in a cave in Wyoming. The first is a 750-pound Mega-Lion and the second is an eleven foot tall bear equipped with huge claws and muscles. How could an ecosystem support two predators of such size and raw power? Using evidence collected in the cave and studying the skeletal design of each combatant, experts are able to recreate a blow by blow account of how these two ice aged monsters fought to the death.

Megalodon, a 50-foot long cousin of the modern Great White Shark was considered the most dangerous predator in the 15 million year old seas. That belief held until a discovery in Japan in 1992 of a fossilized whale equipped with 44 teeth that equaled those of a Tyrannosaurus rex. Watch as experts recreate an undersea battle using modern whale and shark behaviors, and fossilized evidence to see how the two largest killers of the sea fought for supremacy.
