The Upper Triassic is the last epoch in the Triassic period. It began 237 million years ago, and ended 201.3 million years ago. It was after the Middle Triassic epoch, and before the Lower Jurassic epoch.
Many early dinosaur species appeared for the first time during the Upper Triassic. These included Plateosaurus, Coelophysis, and Eoraptor. The discovery of Herrerasaurus and Saurosuchus makes it quite clear that the dinosaurs were taking hold of the land environments.
Pterosaurs were common in the air, and ichthyosaurs dominated the seas.
At the end of the Upper Triassic some event or events caused the extinction of many animal species worldwide. This was the end–Triassic extinction event. It was similar to the more famous event that lead to the extinction of the dinosaurs. No one knows for sure what caused the event.
