|The Permian period extends from about 299.0 to 248.0 million years before the present.|
The Permian follows the Carboniferous (Pennsylvanian in North America) and is followed by the Triassic. The end of the period is marked by a major extinction event, called the Permian-Triassic extinction event.
During the Permian, all the Earth's major land masses except portions of East Asia were collected into a single supercontinent known as Pangea. Pangea straddled the equator and extended toward the poles.
