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.
What is the strongest hypothesis for the mass extinction event at the end of the Permian?
The leading hypothesis is that the end-Permian extinction was caused by massive volcanic eruptions that spewed more than 4 million cubic kilometers of lava over what is now known as the Siberian Traps, in Siberia, Russia.
What happened in the end-Permian extinction?
About 250 million years ago, at the end of the Permian period, something killed some 90 percent of the planet’s species. Less than 5 percent of the animal species in the seas survived. On land less than a third of the large animal species made it. Nearly all the trees died.
What do scientists suggest may have been the cause of the Permian mass extinction event?
Scientists believe a large volcanic eruption in southern China may have contributed to the end-Permian mass extinction 250 million years ago.

What caused mass extinctions on Earth?
What causes mass extinctions? Past mass extinctions were caused by extreme temperature changes, rising or falling sea levels and catastrophic, one-off events like a huge volcano erupting or an asteroid hitting Earth. We know about them because we can see how life has changed in the fossil record.
Why was the Permian mass extinction so important?
The Permian had great diversity in insect and other invertebrate species, including the largest insects ever to have existed. The end-Permian is the largest known mass extinction of insects; according to some sources, it may well be the only mass extinction to significantly affect insect diversity.
What ended the Permian period?
How long did the end Permian extinction last?
252 million years ago
Many geologists and paleontologists contend that the Permian extinction occurred over the course of 15 million years during the latter part of the Permian Period (299 million to 252 million years ago).
