Dictionary

Dinosaur : any of a group (Dinosauria) of extinct often very large chiefly terrestrial carnivorous or herbivorous reptiles of the Mesozoic era — Webster

OneLook, Free Dictionary, Wiktionary, Urban Dictionary

Encyclopedia

Dinosaurare a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 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–Jurassic extinction event 201 million years ago; their dominance continued through the Jurassic and Cretaceous periods. Reverse genetic engineering and the fossil record both demonstrate 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–Paleogene 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. — Wikipedia

    Scientists have discovered the fossils of an iguana-sized reptile, which they named 'Antarctic king,' that lived at the South Pole 250 million years ago (it used to be warmer). Antarctanax was an early cousin of the dinosaurs, and it shows how life bounced back after the world's biggest mass extinction. […]
