Most scientific evidence suggests the causes were global ... The Permian extinction appears to have happened in two or three pulses of extinction. Two or more separate impacts could have possibly accounted for these pulses. Some possible evidence for impact events are meteorite fragments in Australia, rare shocked quartz in both Australia and Antarctica, and craters in Australia. The cause for the end Permian mass extinction, the greatest challenge life on Earth faced in its geologic history, is still hotly debated by scientists.

The end-Permian extinction (EPE), the most severe biotic crisis of the Phanerozoic (Wignall, 2015), led to the fundamental restructuring of terrestrial and marine ecosystems.The consensus view is that the EPE occurred as a consequence of Siberian Traps volcanism, which generated large volumes of sulfate aerosols and CO 2 over a short interval (Burgess et al., 2017), with further contributions ...

Mass extinction. The greatest mass extinction episodes in Earth’s history occurred in the latter part of the Permian Period.Although much debate surrounds the timing of the Permian mass extinction, most scientists agree that the episode profoundly affected life on Earth by eliminating about half of all families, some 95 percent of marine species (nearly wiping out brachiopods and corals ...
