Edmontosaurus is a large duck-billed dinosaur that is part of the Hadrosaur Family. It was common prey for large predatory dinosaurs like T-rex. It can move at 35 miles per hour, and It lived in groups of its own species so they can protect themselves. But unlike most hadrosaurs, Edmontosaurus did not hoot or honk like most hadrosaurs, due to the lack of crest on its head. New fossil evidence shows that Edmontosaurus had a crest, but this was found after Walking with Dinosaurs aired.
Edmontosaurus has been featured in Walking with Dinosaurs, and When Dinosaurs Ruled America.
