Hadrosaurus (Greek: sturdy lizard) is a hadrosaurid dinosaur genus. In 1858, a skeleton of a dinosaur from this species was the first full dinosaur skeleton establishes in North America, and in 1868 it became the first ever mounted dinosaur skeleton. Hadrosaurus foulkii is the only species in this class, and as of 1991 is the official state dinosaur of New Jersey - a judgment brought about by a local teacher, Joyce Berry.
