Gryposaurus was a saurolophine hadrosaur from the Late Cretaceous of western North America. The species Gryposaurus monumentensis was found in Utah, and distinguished by its robust build, which featured an arched, humped nasal ridge on the snout and an especially deep, powerful jaw for an herbivore.
