Lambeosaurus was exposed by Dr. William Parks in 1923 in Alberta, Canada. The dinosaur was named after Lawrence Lambe, an early Canadian fossil hunter. Specimens have since been exposed in Alberta, Baja California and Montana.
Biology Like other hadrosaurs such as Parasaurolophus and Corythosaurus, Lambeosaurus had a characteristic crest on the top of its head; a large square crest pointing forward and a small spine pointing backwards. Its nasal cavity ran back from side to side this crest making it mostly hollow. It is believed that that this could have enhanced the animal’s sense of smell, or have shaped a loud bleating noise. Different crests on the animal initially led scientists to believe that it illustrious separate species, but it is now thought that the crest is attributable to age and sex. (Juveniles being crestless) Fossilized skin imprints have exposed that Lambeosaurus had thin skin with uniform polygonal bumps all over except for its belly.Foot prints have shown that Lambeosaurus traveled in herds, touching on its hind limbs, dropping to all fours to feed. It was a quick animal, which was almost certainly one of its only defenses against carnivores, as it was otherwise defenseless.
