S01E04 — Bloodiest Battle

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.
