Hadrosaurs or Duck-Billed Dinosaurs were a very successful group of plant-eaters that thrived throughout western Canada and around the globe during the Late Cretaceous. Hadrosaurs lived as part of a herd, dining on pine needles, horsetails, twigs and flowering plants.

They are ornithischians — an extinct clade of mainly herbivorous dinosaurs characterized by a pelvic structure superficially similar to that of birds. They are close relatives and possibly descendants of the earlier iguanodontid dinosaurs. They had slightly webbed, camel-like feet with pads on the bottom for cushioning and perhaps a bit of extra propulsion in water. They were primarily terrestrial but did enjoy feeding on plants near and in shallow water. There had a sturdy build with a stiff tail and robust bone structure.
