A bipedal/quadrupedal herbivore the Lambeosaurus was one of the largest of the crested duckbill dinosaurs. Distinctive from it’s hatchet looking hollow cranial crest, which was would resonate to give a distinctive sound in each species.

The Lambeosaurus lived in the Late Cretaceous in North America but fossil finds have been made in Canada and Mexico too.

Lambeosaurus had a beak for breaking off leaves and fruit and teeth at the back for grinding. As the teeth wore out, they were replaced.

It’s been suggested from one fossil deposit know as a ‘bonebed’ contain hundreds of jumbled-up skeletons buried by floods, included specimens of Lambeosaurus, along with Corythosaurus and several other crested duckbill dinosaurs shared the same habitat and may even have migrated in huge mixed herds.
