Parasaurolophus

About Parasaurolophus Parasaurolophus was discovered in Alberta, Canada in 1922 by William Parks. This dinosaur was a typical hadrosaur or duckbilled dinosaur, with a toothless bill, rows of cheek teeth, powerful rear legs, and a prominent head crest. Scientists believe that Parasaurolophus used this crest like a horn, allowing it to make very loud calls to distant companions. The fossils found in Alberta were fairly complete, and consisted of an almost complete skeleton.
