Corythosaurus is a genus of hadrosaurid "duck-billed" dinosaurs from the Upper Cretaceous Period, about 80 to 74 million years ago. This phase lies in the Campanian age of the Cretaceous period of the Mesozoic Era. They had hundreds of small interlocking teeth at the back of their jaw, allowing them to crush and grind plant matter. The bony crest on top of its head contained its nasal passage and may have been used as a sounding device. It had a long, heavy tail and probably weighed three to five tons. The first fossil evidence of Corythosaurus was discovered in the Judith River Formation, which extends from the Canadian province of Alberta to Montana in the United States, and was described in 1914.
