Hadrosaurus

Hadrosaurus (pronounced /ˌhædrɵˈsɔrəs/, from Greek: ἁδρος, hadros + σαυρος, sauros = sturdy lizard) is a dubious genus of hadrosaurid dinosaur. In 1858, a skeleton of a dinosaur from this genus was the first dinosaur skeleton known from more than isolated teeth to be found in North America. In 1868, it became the first ever mounted dinosaur skeleton. Hadrosaurus foulkii is the only species in this genus and has been the official state dinosaur of New Jersey since 1991.
