Description

Dinosaurs are a diverse group of reptiles] of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 231 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic鈥揓urassic extinction event 201 million years ago; their dominance continued through the Jurassic and Cretaceous periods. The fossil record indicates that birds are modern feathered dinosaurs, having evolved from earlier theropods during the late Jurassic Period. As such, birds were the only dinosaur lineage to survive the Cretaceous鈥揚aleogene extinction event 66 million years ago. Dinosaurs can therefore be divided into avian dinosaurs, or birds; and non-avian dinosaurs, which are all dinosaurs other than birds. This article deals primarily with non-avian dinosaurs.
