PERMIAN Meaning and
Definition
-
Permian refers to a geologic period that occurred approximately 299 to 251 million years ago, spanning the late Paleozoic era. It is named after the Perm region in Russia, where important geological formations from this time were first studied. The Permian period is characterized by significant climate changes, the formation of supercontinents, and the emergence of diverse life forms.
During the Permian, Earth experienced alternating periods of warm and cold temperatures, resulting in glaciations and ice ages. This climatic variability had a substantial impact on the planet's ecosystems and the evolution of organisms. The period was marked by the collision and merging of several continents, forming the supercontinent Pangaea. This uniting of landmasses transformed ocean currents and climates, influencing the distribution of life across the globe.
The Permian witnessed the flourishing of a vast range of species, including abundant marine life such as coral reefs, ammonites, and shellfish, as well as a diversity of plants and insects. However, it also witnessed the largest known mass extinction event in Earth's history, known as the Permian-Triassic extinction. This catastrophe wiped out almost 90% of marine species and around 70% of terrestrial species. The causes of this mass extinction are still debated and may involve a combination of volcanic activity, climate change, and other factors.
Permian rock formations are of great scientific interest, as they hold valuable information about the Earth's ancient ecosystems, geological processes, and the history of life on the planet.
