Dinosaurs (meaning "terrible lizards") are a varied group of archosaur reptiles. They were the dominant land animals of the Mesozoicera. Over 500 different genera of dinosaurs are known. Fossils of dinosaurs have been found on every continent, and there are still frequent new discoveries.
Dinosaurs appeared in the Upper Triassic, about 230 million years ago.The earliest date of a dinosaur fossil is that of Eoraptor, 231.4 to 228 mya. By the early Jurassic they were the top land vertebrates, and dominated most environments on land. They continued until the sudden K/T extinction event 66 million years ago.
From the fossil record, we know that birds are living feathered dinosaurs. They evolvedfrom the earliest theropods during the late Jurassic. And so they were the only line of dinosaurs to survive to the present day.
Dinosaurs had adaptations which helped make them successful. The first known dinosaurs were small predators that walked on two legs. All their descendants had an upright posture, with the legs underneath the body. This transformed their whole life-style. There were other features. Most of the smaller dinosaurs had feathers, and were probably warm-blooded. This would make them active, with a higher metabolism than modern reptiles. Social interaction, with living in herds and co-operation seems very likely for some types.
The first fossils were recognised as dinosaurs in the early 19th century. Some of their bones were found much earlier, but were not understood. William Buckland, Gideon Mantell and Richard Owen were scientists who saw these bones were a special group of animals. Dinosaurs are now major attractions at museums around the world. They have become part of popular culture. There have been many best-selling books and movies. New discoveries are reported in the media.

Dinosaurs are a group of reptiles that have lived on Earth for about 245 million years. In 1842, the English naturalist Sir Richard Owen coined the term Dinosauria, derived from the Greek deinos, meaning “fearfully great,” and sauros, meaning “lizard.” Dinosaur fossils have been found on all seven continents.
