Hadrosaur (duck-billed dinosaur)
~ 30 – 50 feet
~ 5 – 9 tons
Montana, North Dakota, South Dakota, Wyoming, Colorado, Saskatchewan and Alberta
Late Cretaceous Period
A specimen of Edmontosaurus found in Alberta revealed that this dinosaur had a fleshy frill on its head, like a rooster’s comb. Edmontosaurus was a large duck-billed dinosaur, but some of the largest individuals discovered were previously thought to represent a distinct giant species named Anatotitan. The large skeleton on display at the Carter County Museum is an example of an Edmontosaurus that was previously called Anatotitan.
