Dinosaurs are 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 TriassicJurassic extinction event 201. 3 million years ago, their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are the only extant dinosaurs on Earth, having evolved from feathered dinosaurs. Birds evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage to survive the CretaceousPaleogene extinction event approximately 66 million years ago. Dinosaurs can therefore be divided into avian dinosaurs, or birds, and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Due to birds being dinosaurs, and dinosaurs being reptiles, this makes birds reptiles, albeit highly evolved and specialized reptiles. Dinosaurs are a varied group of animals from taxonomic, morphological and ecological standpoints. Birds, at over 10, 700 living species, are among the most diverse group of vertebrates. Using fossil evidence, paleontologists have identified over 900 distinct genera and more than 1, 000 different species of non-avian dinosaurs.
