postPermianTriassic

The post-Permian-Triassic period, also known as the Permian-Triassic extinction event, was a catastrophic event that occurred approximately 252 million years ago. It is one of the five major mass extinctions in Earth's history, and it is notable for the sheer magnitude of species that went extinct. The event is estimated to have wiped out around 96% of marine species and 70% of terrestrial vertebrate species. The cause of this extinction event is still a subject of ongoing debate among scientists, with theories ranging from volcanic activity, asteroid impacts, climate change, and even a combination of these factors.

The Permian-Triassic extinction event marked the end of the Paleozoic era and the beginning of the Mesozoic era. It is often considered a turning point in Earth's history, as it led to a significant change in the composition of life on Earth. The event is also significant because it is one of the few times in Earth's history where a single event has had such a profound impact on the planet's biosphere. The recovery of life after this event took millions of years, and the diversity of life that existed before the extinction event never fully returned. The study of this event continues to provide valuable insights into the resilience of life on Earth and the factors that can lead to such catastrophic events.
