Hadrosaurus is a genus of hadrosaurid ornithopod dinosaurs that lived in North America during the Late Cretaceous Period about 80 million to 78 million years ago. They weighed up to 2 to 4 tons and have been primarily quadrupedal dinosaurs as the rear legs were the main weight-bearing features and could have still reared up on their hind legs to reach higher food, and also been able to ‘run’ on just the rear legs when escaping predators. Their teeth were incredibly complicated with up to 1400 of them. The forelimbs were not as heavily built as the hindlimbs but were long enough to be used in standing or movement. it looked like that of Kritosaurus, which lived at the same time and place, or like that of later hadrosaurids, such as Edmontosaurus.
