The end-Permian mass extinction (EPME) at ∼252 Ma was the most severe extinction in the Phanerozoic. Marine ecosystems devastated by the EPME had a highly prolonged recovery, and did not substantially recover until after the Smithian–Spathian substage boundary (SSB) of the Lower Triassic (5 to 9 Ma after the EPME).First, we need to be clear on what we mean by ‘mass extinction’. Extinctions are a normal part of evolution: they occur naturally and periodically over time. 1 There’s a natural background rate to the timing and frequency of extinctions: 10% of species are lost every million years; 30% every 10 million years; and 65% every 100 million years. 2 It would be wrong to assume that species ...Sep 19, 2018 · The end-Permian mass extinction, which took place 251.9 million years ago, killed off more than 96 percent of the planet's marine species and 70 percent of its terrestrial life—a global ...
