Parasaurolophus

Parasaurolophus is a hadosaurid dinosaur from late Cretacious North America. It was known for having a large tube-like Creasy on its face which it used to make trumpeting sounds. It was not in Jurassic Park but was recreated on Isla Sorna. They are observed to make mixed herds with Apatosaurus. They do that because Parasaurolophus has good eyesight for spotting predators while Apatosaurus can defend them with their whip-like tail.
