It is the last period of the Paleozoic Era, following the Carboniferous Period and preceding the Triassic Period of the Mesozoic Era. The Permian System has been subdivided into three series. They are the Cisuralian, Guadalupian and Lopingian Series and contain nine stages. The Permian Period was extremely important in terms of its geological history because it witnessed a process from the greatest icehouse stage to the biggest biological mass extinction stage during the Phanerozoic. The latter wiped out about 95% of the marine species and 75% of terrestrial species on the earth at the end-Permian.
