Lambeosaurus was a crested, duck-billed dinosaur. Its forward-leaning, hollow, bony crest was as big or bigger than the rest of its skull and may have been used to produce sounds, enhance its sense of smell, and/or add to its courtship display. Lambeosaurus' nostrils went up through the crest. Its snout was narrow and ended in a beak that was wide and blunt.

Lambeosaurus walked and ran on two legs, and was a relatively fast dinosaur. It probably went on all fours to forage for plants.
