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
