The end of the Permian period was characterized by a mass extinction of a significant number of species, including about 95% of marine invertebrates. This event is known as the Permian-Triassic extinction event or the Great Dying. While some terrestrial species, including amphibians and reptiles, were also affected, it was primarily shallow-water marine species that suffered the most severe losses. Dinosaurs and mammals did not evolve until millions of years after the Permian period.
