The new research aimed to study how such polar ecosystems changed during the mass extinction at the end of the Permian period 250 million years ago, he said.

Although research is still ongoing on what caused the mass extinction, many scientists believe 90 per cent of all species were wiped out from the face of the earth, including the polar forest, because of higher global temperatures and ocean acidification caused by an injection of carbon dioxide in the atmosphere spanning over 200,000 years.
