PERMIAN SYSTEM Meaning and
Definition
-
The Permian System refers to a geologic period and a stratigraphic division of Earth's history that occurred approximately 299 to 251 million years ago, making it the final period of the Paleozoic Era. It is named after the region of Perm, Russia, where rocks from this time were extensively studied.
The Permian System is characterized by significant geological events and the emergence of various life forms. During this time, the Earth experienced widespread tectonic activity, including the formation of the supercontinent Pangaea. The landscape consisted of vast deserts, extensive shallow seas, and densely forested regions, offering diverse habitats for life to evolve.
The Permian System witnessed the dominance of reptiles, particularly the emergence of sauropsids or reptile-like ancestors of dinosaurs, turtles, and birds. It was also a period of diversification for other organisms, including primitive mammals, as well as the rise of many insects and coniferous vegetation. Additionally, coral reefs flourished in the shallow seas.
The Permian System concluded with one of the most catastrophic events in Earth's history, the Permian-Triassic extinction event. This mass extinction wiped out almost 96% of marine species and 70% of terrestrial vertebrate species. It is believed to have been caused by a combination of volcanic activity, climate change, and the release of large amounts of methane gas. The disappearance of numerous organisms marked the end of the Permian and led to the dawn of the Mesozoic Era.

Etymology of PERMIAN SYSTEM
The term "Permian System" refers to a geological period and rock system named after the Russian region of Perm. Its etymology can be traced back to the 19th century when German mineralogist and geologist Friedrich von Alberti named the period after the city of Perm and its surrounding area in recognition of the rich Permian rocks found there. Von Alberti's decision to name the period Permian was made to honor the location where significant Permian-age geological formations were first described and studied.
