What is the permian extinction
The Latest Permian Mass Extinction (LPME) was the largest extinction event in Earth's history to date, resulting in the loss of between 80-90% of life on the planet. Despite extensive research, the exact cause of the dramatic changes in climate during this time remains unknown. A team of internatOcean animals at the top of the food chain recovered first after a cataclysm at the end of the Permian period. The extinction was triggered by events resembling the changes brewing in today's oceans.

It marked the end of the Permian Epoch and the beginning of the Triassic Epoch. About three quarters of all land life and ...We observe abrupt decreases in [U] and δ(238)U across the end-Permian extinction horizon, from ∼3 ppm and -0.15‰ to ∼0.3 ppm and -0.77‰, followed by a gradual return to preextinction values over the subsequent 5 million years. These trends imply a factor of 100 increase in the extent of seafloor anoxia and suggest the presence of a ...Abstract: Wildfire has been implicated as a potential driver of deforestation and continental biodiversity loss during the end-Permian extinction event (EPE; ∼ 252 Ma). However, it cannot be established whether wildfire activity was anomalous during the EPE without valid pre- and post-EPE baselines. Here, we assess the changes in wildfire activity in the high-latitude lowlands of eastern ...
Aug 3, 1999 · The disappearance of the dinosaurs during the end-Cretaceous mass extinction 65 million years ago is perhaps the best known event, but the end-Permian (ca. 251 million years ago) extinction was, without question, the most profound.

The Permian (along with the Paleozoic) ended with the Permian–Triassic extinction event, the largest mass extinction in Earth's history (which is the last of the three or four crises that occurred in the Permian), in which nearly 81% of marine species and 70% of terrestrial species died out, associated with the eruption of the Siberian Traps.
