Gryposaurus was a genus of duckbilled dinosaurs that lived about 83 to 75 million years ago, in the Late Cretaceous period of North America. It had several different types of scalation: pyramidal, ridged, limpet-shaped scutes upwards on the flank and tail. It is also known as a duck-billed dinosaur because of the specially adapted mouth that was suited for snipping vegetation. The prominent nasal arch found in this genus is formed from the paired nasal bones and rises into a rounded hump in front of the eyes, reaching a height as tall as the highest point of the back of the skull. Gryposaurus lacked an elaborate hollow crest which is the signature feature of the lambeosaurine hadrosaurids but might have had a display feature made up of soft tissue rather than the hollow bony crests.
