End permian extinction cause.
Another possible cause of the extinction is an impact event, much like the meteor that famously killed the dinosaurs at the end of the Cretaceous Period. 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.
End-Triassic extinction, global extinction event occurring at the end of the Triassic Period that resulted in the demise of some 76 percent of all marine and terrestrial species and about 20 percent of all taxonomic families.

A question remains though, whether conodonts are reliable indicators of seawater temperature. While the causes of this global catastrophe are unknown, an MIT-led team of researchers has now established that the end-Permian extinction was extremely rapid, triggering massive die-outs both in the oceans and on land in less than 20,000 years — the blink of an eye in geologic time. The researchers also found that this time period coincides ...Today’s oceans are absorbing carbon about an order of magnitude faster than the worst case in the geologic record — the end-Permian extinction.
