There was widespread geologic uplift, resulting in the formation of Pangea. The major climatic characteristics of the period are aridity and glaciation.
The end of the Permian was marked by the largest mass extinction in the history of life on Earth, in which many groups of organisms died out including almost all marine invertebrates. On land, a relatively smaller extinction of diapsids and synapsids cleared the way for other forms to dominate, and led to what has been called the Age of Dinosaurs.
