The Triassic is the first and shortest period of the Mesozoic Era, spanning about 251.902 to 201.4 million years ago. It began in the aftermath of the Permian-Triassic extinction and ended with the Triassic-Jurassic extinction event; archosaurs, including the early dinosaur lineages, were the chief terrestrial vertebrates while Pangaea began to rift apart late in the period.
