How did the permian extinction happen. Ocean animals at the top of the food chain recovered first after a cataclysm at the end of the Permian period. The extinction was triggered by events resembling the changes brewing in today's oceans.
New research from the University of Washington and Stanford University combines models of ocean conditions and animal metabolism with published lab data and paleoceanographic records to show that the Permian mass extinction in the oceans was caused by global warming that left animals unable to breathe.

Andrew Alden. Updated on March 17, 2017. The greatest mass extinction of the last 500 million years or Phanerozoic Eon happened 250 million years ago, ending the Permian Period and beginning the Triassic Period. More than nine-tenths of all species disappeared, far exceeding the toll of the later, more familiar Cretaceous-Tertiary extinction.The main reason was that the end-Permian crisis was much more severe than any other mass extinction, wiping out 19 out of every 20 species. With survival of only 5% of species, ecosystems had been destroyed, and this meant that ecological communities had to reassemble from scratch.Ocean animals at the top of the food chain recovered first after a cataclysm at the end of the Permian period.
