Duck-Billed Dinosaur

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.
