Non avian dinosaurs appeared during the Carnian stage of the Triassic period about 220 million years ago. They diversified in the Jurassic and even more in the Cretaceous, but they died out 65.5 million years ago. All non avian dinosaurs lived during the Mesozoic era, but birds, which are a group of dinosaurs, continue to exist today.
