What is the permian extinction
Pseudophillipsia (Late carboniferous to Late Permian) Final extinction. Exactly why the trilobites became extinct is not clear; with repeated extinction events (often followed by apparent recovery) throughout the trilobite fossil record, a combination of causes is likely. After the extinction event at the end of the Devonian period, what ...The Permian Mass Extinction was the largest extinction in Earth's history, which is maybe lesser known since it's kind of old news— 252 million years old to be (somewhat) precise, according to Britannica. While this mass murder was taking nearly 95% of life in the ocean and 70% of life on land, Pangea was still rocking out, dinosaurs weren't ...1. Summary. The video discusses the world's most severe extinction event, known as the End-Permian Mass Extinction. The video's theory behind the cause of the End-Permian Mass Extinction is an ancient volcano chain, which spewed out carbon dioxide into the atmosphere, trapping heat and causing a global warming event.

The Permian Mass Extinction 251.9 million years ago, otherwise known as “The Great Dying,” was the closest this planet has come to extinguishing all complex life on Earth. Around 90% of all species died out in this single event, a worse toll even than the Cretaceous extinction that wiped out the dinosaurs."All the big top predators in the late Permian in South Africa went extinct well before the end-Permian mass extinction. We learned that this vacancy in the niche was occupied, for a brief period, by Inostrancevia," says Pia Viglietti, a research scientist at the Field Museum in Chicago and a co-author of the new study in Current Biology.Mar. 27, 2020 — Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from ...
After each great extinction event, there is a scramble for supremacy among the survivors. For instance, after the [Permian-Triassic] extinction event 250 million years ago, the dice were re-rolled. Most of the proto-mammals, which had been dominant, were wiped out. The big winners when the dust cleared were reptiles, and their dominion ...The Permian–Triassic mass extinction (PTME; ca. 252 Ma) coincided with rapid global warming that produced one of the hottest intervals of the Phanerozoic 1,2,3,4,5, which was likely triggered by ...The Permo-Triassic Extinction. The end of the Permian period 252 million years ago saw the greatest mass extinction in the geological record. Many theories have been advanced as to the cause, including a fall in sea level, severe climate change induced by methane release, intense volcanism, impact by a bolide, overturn of a stratified, sulfidic ...Mass extinctions. Mass extinctions are episodes in which a large number of plant and animal species become extinct within a relatively short period of geologic time—from possibly a few thousand to a few million years. After each of the five major mass extinctions that have occurred over the last 500 million years, life rebounded.The Permian-Triassic (P-Tr) mass extinction of 252 million years (Ma) ago caused a transformation among marine communities from the Paleozoic evolutionary fauna to the modern evolutionary fauna (), although there was a prolonged delay of recovery in the Early Triassic ().Biodiversity data, compiled from global fossil databases and case studies, provide much detail on the magnitude and duration ...
Before the reign of the dinosaurs, there was an even more deadly extinction at the end of the Permian Era, 252 million years ago. This one was triggered by massive volcanic eruptions, which ...The Permian-Triassic mass extinction (PTME; 252million years ago (Ma)) was the most severe biological crisis of the Phanerozoic (FIg. 1). It almost completely eliminated Palaeozoic faunaDiscovering this new mass extinction event adds to the belief that five key extinction events have occurred since the beginning of the Cambrian Period, about 539 million years ago. ... the Permian ... ….

Erwin (1996) coined this critical interval in Earth history as the "Mother of Mass Extinctions."
