CORYTHOSAURUS (ko-RITH-o-sawr-us) "Helmet Lizard" (Greek korythos = helmet + sauros = lizard, referring to the shape of its CREST)

A LAMBEOSAURINE HADROSAUR. This Late Cretacious dinosaur measured 30 feet (9.1 m) from the tip of its duck-like bill to the end of its long, heavy TAIL. It weighed 2 to 3 tons (1.8 to 2.7 metric tons). A hollow, helmet-shaped crest adorned its long, narrow head, and hundreds of TEETH lined its jaws. Its SKIN had a pebbly surface, similar to the texture of a football. Three rows of larger bumps, or tubercles, covered the belly.

Corythosaurus was a BIPEDAL land dweller and probably a fast runner. The Corythosaur was strictly a herbivour and its diet consisted primarily of twigs, leaves, and pine needles. These dinosaurs were primaraily located in the Alberta and Montana states. A nearly complete skeleton has been bound in Alberta, Canada.
