Dinosaurs are a species of reptiles that first appeared during the Triassic period, about 230-240 million years ago, and then continued through the Jurassic and Cretaceous periods. At some point during the Cretaceous-Paleogene an extinction event wiped out the dinosaurs, roughly 66 million years ago.
