Fossil remains for this Dinosaur have been found in North America
ProSaurolophus was an early member of the duck-billed dinosaur family. It was very similar to Saurolophus and probably represents an evolutionary step in that dinosaur's history. Like the other duck-billed dinosaurs, it had hind legs much longer than its front legs, which means it could walk and stand on two legs. It also had hundreds of teeth packed closely together to form what is called a dental battery that was used to grind tough plant fiber into mushy pulp.
There is some fossil evidence to suggest that ProSaurolophus
could have grown to a size of almost 50 feet long. Its crest
was shorter than that of
Saurolophus and it had a smaller bill.
