Parasaurolophus was a bus-sized dinosaur that had a long, hollow, bony head crest that may have used to make sounds. This plant-eating dinosaur lived during the late Cretaceous period, about 76-65 million years ago.

Anatomy: Parasaurolophus grew to be about 40 ft (12 m) long and 9 feet (2.8 m) tall at the hips. It weighed about 2 tons. It had pebbly-textured skin, a spoon-shaped beak, and a pointy tail. It may have had webbed fingers, giving it a mitten-like hand, but some paleontologists argue that the web-like fossilized hands are an artifact of the fossilization process. Its sight and hearing were keen, but it had no natural defenses. It had a toothless beak and numerous cheek teeth.

Fossils and Name: Parasaurolophus means "beside crested lizard." It was named by Dr. William A. Parks in 1922. Parasaurolophus fossils have been found in North America (in Alberta, Canada, and in New Mexico and Utah in the USA).
