What was the permian extinction.

Permian Extinction. The largest extinction ever in the history of Earth is the Permian extinction, an event that occurred roughly 252 million years ago. Scientists estimate that 90 percent of marine species disappeared over the course of about 60,000 years. The extinction was a response to dramatic changes in the Earth's atmosphere.The Extinction marking the end of the Cretaceous period 65 Million years ago, where Iridium is found worldwide, provided conclusive evidence for a meteorite impact as the cause. The debate over the cause of the Largest Extinction in Earth History, Permian Extinction, will continue until more conclusive worldwide evidence is found.2. The Permian-Triassic mass extinction. The PTME comprised two killing events, one at the very end of the Permian (EPME) and a second at the beginning of the Triassic, separated by 60 000 years [].Together, these pulses of extinction accounted for the loss of up to 96% of marine invertebrate species globally [], and similar losses at regional scale, when documented in detail in marine ...Brachiopod extinction across the Permian-Triassic boundary is apparent in the occurrence of fossils in the Park City and Dinwoody Formations.
