Saurolophus

Saurolophus was a large herbivorous dinosaur with a single horn sticking out of the back of its head. This dinosaur was first discovered in North America, and has more recently been found in Mongolia. Its existence on both continents supports the idea that North America and Asia were connected by a land bridge 70 million years ago. There is some debate whether this animal preferred to walk on two legs or four legs.
