Permian mass extinction cause
The three mass extinction events are highlighted in red with stars: P/Tr = end-Permian event, Tr/J = end-Triassic event, K/Pg = end-Cretaceous event. We further highlight the end-Cenomanian event (OAE2) and the Palaeocene–Eocene thermal maximum (PETM). The black arrows indicate the composition of the PCA components, with each arrow indicating ...The Permian mass extinction occurred roughly 248 million years ago and led to the loss of 90-96% of the world's species. Everything from asteroid impacts to volcanic activity, to methane gas ...Although the cause of the Permian mass extinction remains a debate, numerous theories have been formulated to explain the events of the extinction. One of the most current theories for the mass extinction of the Permian is an agent that has been also held responsible for the Ordovician and Devonian crises, glaciation on Gondwana. A similar ...

Warming of the Earth’s climate and associated changes to oceans were the most likely causes of the extinctions. At the end of the Permian Period volcanic activity on a massive scale in what is now Siberia led to a huge outpouring of lava. The eruptions also produced carbon dioxide, a greenhouse gas that helps warm the planet. 7 Ara 2018 ... ... cause of the end-Permian extinction. Magnitude of ...
