One of the last dinosaurs to become extinct, Anatosaurus lived 65 million years ago. Anatosaurus was a duckbill dinosaur and belonged to a family that had jaws shaped like a duck's beak. They were called hadrosaurids and lived for more than 60 million years. Anatosaurus was a typical hadrosaurid. It had up to 1,000 tiny teeth in its mouth for munching vegetation. Many types of Hadrosaurids had a crest, each type shaped differently. Anatosaurus had no crest, but had instead a smooth, rounded head. Anatosaurus had strong back legs and could probably run very fast.

Anatosaurus was built to eat plants, leaves, and small shrubs. One set of remains has been found with pine needles in its stomach, along with seeds and fruit! They could stand erect on their back legs and nibble high branches or rest on their front legs and munch plants. If threatened, they could probably rear up and dash away at great speed.

They had strong tails that provided balance when they were running on their back legs. Some Anatosaurus remains have been found with pieces of skin preserved. This is a very unusual find, and scientists have studied the skin carefully. Anatosaurus skin had a pebbly texture, like the skin of a lizard.
