All of the big five extinctions occurred during the
Rates of extinction documented in the modern day (using extant species and a historical timeframe) match or even exceed rates calculated from fossil turnover during the Big Five mass extinctions. However, these accelerated rates have only been operating for a geologically brief amount of time (a few centuries). The third of the big five extinction events, here, is something that occurred at the end of the Permian, between the Permian and Triassic periods, about 252 million years ago. This is sometimes known as The Great Dying, the biggest known extinction event, during which 96% of all marine and 70% of all terrestrial vertebrates died out.
