Duck-billed Dinosaure

Back to the sheet

This piece is an incomplete jaw of the Edmontosaurus, a herbivorous dinosaur that lived more than 65 million years ago. The Edmontosaurus had neither incisor teeth nor canines, but rather hundreds of tiny teeth aligned on either side of the jaw. When the teeth were worn down by grinding leathery plant matter, they were replaced by new ones that took their place just below. The large flat head of this dinosaur ended in a corneous beak formed somewhat like a duck's beak.

This fossil comes from the Red Deer River area of Alberta. This region is so rich in dinosaur fossils that the Dinosaur Provincial Park was created, which has attached to it the Royal Tyrrell Museum of Palaeontology.
