Abstract. The end-Permian mass extinction was the most severe biodiversity crisis in Earth history. To better constrain the timing, and ultimately the causes of this event, we collected a suite of geochronologic, isotopic, and biostratigraphic data on several well-preserved sedimentary sections in South China.

They record times when major environmental change occurred world-wide. Four of the "Big Five" extinctions were at least partly the result of climate change in the form of global warming (end-Permian; end-Triassic) or cooling (end-Ordovician; Late Devonian).The marine version of the end-Permian extinction took up 100,000 years out of the entire 3,800,000,000 years that life has existed—the equivalent to 14 minutes out of a whole year.
