Lambeosaurus ( lambe’s lizard) was a large, robust, duckbilled dinosaur with a head crest that has often been compared in shape to a hachet. The crest was hollow: the cavity inside was an extension of the nasal passage, and most probably amplified the sound of the animal’s calls. Finds of skeletons as far apart as Canada and Mexico suggest that Lambeosaurus ranged a long way north and south, west of North America’s Late Cretaceous inland sea.
