Permian

Also known as Permian Period, Permian System

The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years, from the end of the Carboniferous Period Ma (million years ago) to the beginning of the Triassic Period 251.902 Ma. It is the sixth and last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia.

AI overview

The Permian is a geologic time period that lasted about 47 million years and occurred roughly 300 to 250 million years ago, marking the final chapter of the Paleozoic Era before the Mesozoic Era began. It matters because understanding this ancient period helps scientists piece together Earth's geological history and the major transitions that occurred in the planet's rocks, climate, and life forms over deep time.

The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids (reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their amphibian ancestors.
