Othnielia

Othnielia rex
(also known as Nanosaurus rex)

Othnielia was discovered in 1977, named after the famous Paleontologist Charles Othniel Marsh. Othnielia ate with a horny beak and self-sharpening cheek plates. As a fast running bipedal dinosaur its primary defense was probably to run away. An ornithopod, Othnielia was probably midway or average intelligence.
