Edmontosaurus was a large, plant-eating, duck-billed dinosaur from the Late Cretaceous period.
Like most other hadrosaurs, it had a toothless beak, with teeth further back in the cheeks. The skull shows signs that Edmontosaurus may have had large inflatable flaps of skin near its nose to attract a mate, or to make a loud honking noise.
