Permian period extinction
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 ...However, if during the late Permian period the lack of dissolved oxygen is believed to be a consequence of a global warming (Zhang et al., 2018a), and during the late Ordovician period – a consequence of a climate cooling (Bartlett et al., 2018), what could cause it during other periods of mass extinctions is not yet clear.The Permian ended with the most extensive extinction event recorded in paleontology: the Permian–Triassic extinction event. 90 to 95% of marine species became extinct, as well as 70% of all land organisms. It is also the only known mass extinction of insects.
