Dryosaurus

Dryosaurus (meaning "tree lizard", the name reflects the forested habitat, not a vague oak-leaf shape of its cheek teeth as is sometimes assumed) was an ornithopod dinosaur that lived in the Late Jurassic period. It was an iguanodont (formerly classified as a hypsilophodont). Fossils have been found in the western United States, and were first discovered in the late 19th century. Valdosaurus canaliculatus and Dysalotosaurus lettowvorbecki were both formerly considered to represent species of Dryosaurus.

Jurassic Park: Operation Genesis
Dryosaurus appeared in Jurassic Park: Operation Genesis as a 1-star herbivore, the only 1-star dinosaur in the game. They serve as a main prey for many carnivores and has no defenses against any carnivore. They enjoy herding and lack defenses so they run away from danger. They are the favored prey for Dilophosaurus and Ceratosaurus. They were probably an important prey item for the latter in real life as well. Dryosaurus, along with the Ceratosaurus, Pachycephalosaurus, Albertosaurus, Torosaurus and Parasaurolophus, are one of the dinosaurs the player is able to start with.
