Hadrosaurus were duck-billed, plant-eating dinosaurs that lived during the late Cretaceous period, roughly 80 million years ago. They were herbivores with a toothless bill but many cheek teeth, and ran on four legs. They was about 9 metres long and 4.5 metres tall, and lived near the coast of New Jersey, U.S.A.
