Dryosaurus (DRY - oh - SAW - rus) was an iguanodontid ornithopod dinosaur. They lived during in the Late Jurassic period. Its name meaning "Oak lizard", due to the vague oak shape of its cheek teeth.

This diminutive herbivore is both swift and agile. Lacking any other defensive abilities, its only means of defense is to flee any predators. It lives in herds to guarantee early warning of nearby predators.[2]

Novels Edit

Dryosaurs are mentioned in the chapter The Park of the first novel:

In the harsh quartz lights, the hypsilophodont's green head hung down out of the sling, the tongue dangling, the eyes dull. ... The hypsy was a small dryosaur, seven feet long, weighing about five hundred pounds.[3]

The dryosaur coughed, and then moved slowly across the field, away from the lights.[4]

The Dryosaurus is mentioned to be dark green with mottled brown spots.
