The LARGEST MASS EXTINCTION of life on our planet occurred at the end of the Permian when ~ 96% of all species perished. Evidence suggests that massive volcanic eruptions, one or more meteor impacts, and/or a rapid temperature increase due to a sudden release of methane from the ocean bottoms may have contributed to this extinction. “Background” extinction rates are particularly elevated during the Early Paleozoic (Cambrian and Ordovician) (12, 13). For this reason, these periods are sometimes considered separately in paleontological analyses (12, 14). For example, it has been proposed that the high Early Paleozoic extinction rates reflected an interval ofThe Late Devonian mass extinction, which occurred 374.5 Ma, is one of the ‘Big Five’ mass extinctions in Earth history.
