Permian mass extinction cause
The causes of this extinction are poorly understood. The end-Permian extinction (also called P/T or Permian/Triassic) was the largest recorded extinction event so far in the history of life, with an estimated 96 percent of all marine species and 70 percent of all terrestrial species lost.The largest mass extinction in the Earth’s history occurred during the latter part of the Permian Period. This mass extinction was so severe that only 10 percent or less of the species present during the time of maximum biodiversity in the Permian survived to the end of the period.

Jul 15, 2023 · The Early Triassic after the end-Permian mass extinction was a time of repeated environmental degradation, which delayed biotic recovery. Although repeated volcanic activity during the Early Triassic has been cited as the cause, the evidence for this hypothesis needs to be confirmed with convincing proxies. Retallack et al. (2006) suggested a link between a period of high extinction and turnover in terrestrial tetrapod faunas and the marine Guadalupian mass extinction, but it was only with improvements in biostratigraphic resolution and geochronological constraints on the mid-late Permian terrestrial sequence of the Main Karoo Basin in South Africa that such comparisons could be directly ...
