Parasaurolophus (near-crested lizard) was a duck-billed, herbivorous dinosaur that lived during the Late Cretaceous period, in what is now North America. Originally discovered by a field party from the University of Toronto, there are three known species of Parasaurolophus. Similar to other duck-bill dinosaurs during the Late Cretaceous, Parasaurolophus has a long, thick crest that extends from the back of the head, which is thought to have been used for communication.
In Jurassic Park: Trespasser, Parasaurolophus is a peaceful herbivore that roams across Isla Sorna during Anne’s trek. They are usually docile animals, and often scatter and flee from Anne if she attempts to approach them. Unlike their movie counterparts, Parasaurolophus has a bright orange body, with black splotches all over the hide. Also unlike their movie counterparts, these dinosaurs have a skin flap that hangs from their crests behind the head. This feature had not yet appeared in Jurassic Park up until now, and has not re-appeared since.
