CORYTHOSAURUS
"Helmet Lizard"

ANATOMY
Corythosaurus was a large, plant-eating, duck-billed dinosaur (family Hadrosauridae). It was about 30-33 feet (9-10 m) long, 6.6 feet (2 m) tall at the hips, and may have weighed up to 5 tons.

It had a hollow, bony crest on top of its long head in the shape of a helmet flattened on the sides (Corythosaurus means "helmet lizard"). Corythosaurus' nostrils went up through the crest. The crest may have been used to make sounds, as a cooling device, courtship displays, and/or as a sense-of-smell enhancer (Corythosaurus' olfactory lobes, the part of the brain that sense smell, were located within the crest). Males had larger crests than females and juveniles.

Corythosaurus had a toothless beak and hundreds of cheek teeth that it used to grind up its food. It walked on two legs (or four), had shorter arms, and a long, heavy tail. It had no natural defenses. Its femur (thigh bone) was 108 cm long.



WHEN CORYTHOSAURUS LIVED
Corythosaurus lived during the Cretaceous period, roughly 80 to 65 million years ago, toward the end of the Mesozoic, the Age of Reptiles. Among the contemporaries of Corythosaurus in the late-Cretaceous (in North America) were Albertosaurus, Nanotyrannus, Parasaurolophus, Euoplocephalus, Kritosaurus, and Pachyrhinosaurus.

CORYTHOSAURUS BEHAVIOR
Corythosaurus was a herding animal that may have migrated from shorelines to higher ground to reproduce.

DIET
Corythosaurus was an herbivore, perhaps eating pine needles, conifers, ginkgos, seeds, cycads, twigs, and magnolia leaves.

INTELLIGENCE
Corythosaurus was an ornithopod, whose intelligence (as measured by its relative brain to body weight, or EQ) was midway among the dinosaurs.

LOCOMOTION

Corythosaurus walked and ran on two legs, and was a relatively fast dinosaur. It may have gone on all fours to forage for low-lying plants.

DISCOVERY OF FOSSILS
Corythosaurus was named by Barnum Brown in 1914 from a fossil found in Alberta, Canada. Fossils have been found in North America, including Montana, USA, and Alberta, Canada. Fossilized skin with a pebbly texture has been found.
