Duck-Billed Dinosaur

Part of Hall of Ornithischian Dinosaurs.

Fossil skeleton of a duck-bill dinosaur mounted to show the animal's skull reaching down toward the ground with its square-shaped bill.

Anatotitan was a duck-billed dinosaur, one of the most widespread dinosaur groups. About 70 million years ago, duck-billed dinosaurs lived in the Americas, Europe, and Asia. Their habitats varied from forests in river valleys to swamps in coastal floodplains.

In addition to their ducklike beaks and webbed front feet, some of the fossil "mummy" duck-billed dinosaurs had powerful jaws with hundreds of blunt teeth that were ideal for grinding fibrous land plants.
