The Corythosaurus is an upcoming lambeosaurine.
In Real Life
Corythosaurus was a large, plant-eating, duck-billed dinosaur (family Hadrosauridae). It was about 9-10 meters (30-33 feet) long, 2 meters (6.5 feet) tall at the hips, and may have weighed up to 4.5 tonnes (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' 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 had shorter arms, and a long, heavy tail. It had no natural defenses. Its femur (thigh bone) was 108 cm long.
