Resources About Dinosaurs For Kids

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–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. This article deals primarily with non-avian dinosaurs.

List of Quadrupedal Dinosaurs

The earliest dinosaurs known are bipedal and this may well be the original posture of the entire group. Quadrupedal dinosaurs appear a little later in the fossil record than the bipedal dinosaurs, but are equally interesting and considerably more varied. Almost all quadrupedal dinosaurs are herbivores. Most dinosaurs were obligate quadrupeds; well-known groups of dinosaurs that normally walked on all four legs […]
