|Group:||Dinosauria - Hadrosauridae|
|Original Specimen Location:|
Species: E. Regalis
A large hadrosaurid known from the late Cretaceous, Edmontosaurus was a herbivore equipped with a duckbill snout and battery of deeply recessed teeth. Judging from the recovered specimens, Edmontosaurus could reach up to 13m in length, making it one of the largest hadrosaurids known. At one collection site, a skin impression was fossilized along with the animal. Evidence indicates that the skin was scaly and leathery, much like modern reptiles.
