Phanerozoic

The Permian is the sixth and last period of the Paleozoic Era, spanning about 298.9 to 251.902 million years ago; the following Triassic belongs to the Mesozoic. It ended with the Permian-Triassic extinction event, the most severe mass extinction recorded in the fossil record, associated with the eruption of the Siberian Traps.
