The Edmontosaurus River Herds That Ruled Hell Creek

Edmontosaurus was one of the great herd animals of the final dinosaur world—a powerful duck-billed dinosaur that moved through the rivers, floodplains, and forests of Hell Creek. In this video, we explore the life of Edmontosaurus, from massive herds and feeding behavior to predators like Tyrannosaurus rex, fossilized skin impressions, nesting, migration, and survival in the last days of the Cretaceous. Discover how this remarkable dinosaur lived alongside some of the most famous creatures in prehistory before the asteroid brought their world to an end.
