Definition

Noun: 1. A type of theropod dinosaur: An ornithomimid is a member of a family (Ornithomimidae) of lightly built, medium-sized, bipedal dinosaurs that lived during the Cretaceous period. They are characterized by their extremely long limbs and necks, small heads, large brains relative to body size, and large eyes. Their name means "bird mimic," due to their superficial resemblance to modern ostriches.
