Saurolophus is a well-known member of the duckbill family of dinosaurs. It had a small crest on the top of its head, highlighted by a fairly short and hollow tube. Like the other duck-billed dinosaurs, it had a large, flat beak (like a duck) at the front of its mouth and hundreds of teeth packed closely together to form what is called a dental battery. These were used to grind tough plant fiber into mushy pulp so that it could be digested more easily.

The Asian species of this genus, S. angustirostris, was considerably larger than the Saurolophus specimen found in Southwestern Canada. Discovered in 1911, this was the most complete Canadian dinosaur found up to that time. The Canadian species is about 7 feet (2 m) shorter than its Asian relative.
