Hadrosaurus (HAD-row-sore-us)
A Late Cretaceous ornithopod from USA (New Jersey and Mexico) and Canada (Alberta) [Greek hadros, "heavy"]. It had a deep, narrow face with a rounded bump in front of the eyes. The bump was probably covered by thick, rough skin. (Perhaps only the males had this bump.) Hadrosaurus also had a soft comb that ran along its back.
Length: 8-10 m
