Melting ice within permafrost in the Russian arctic is revealing ancient life that has been buried there for thousands of years.
An investigation by Sky News into the environmental damage caused by the thawing of this region’s vast carbon stores found parts of mammoth tusk as well as fragments of woolly rhinoceros bone.
The animals once roamed the Arctic grasslands before becoming extinct: rhinos around 14,000 to 15,000 years ago and mammoths about 10,500 years ago, at the end of the last ice age.

The bone and tusk fragments were found in Duvanny Yar, near Chersky in the Siberian Arctic – home to international research stations where scientists congregate to study the impact of the retreating ice.

Last year, scientists discovered the well-preserved carcass of a woolly rhino in eastern Siberia thought to have been frozen for tens of thousands of years.
Melting permafrost in the Abyisky region of Yakutia in north-eastern Russia was the cause of the discovery, with much of the rhino’s soft tissue still visible, including part of the intestines and genitals, and a small nasal horn, which was remarkable since this often decomposes quickly.
The thawing ice also discloses plant life frozen in time from the Pleistocene epoch – the period that spanned from 2.6 million to 11,700 years ago.
But any revelations about the Russian arctic’s fascinating natural history comes at a huge price. Climate change is causing the permafrost to melt, releasing large amounts of pent-up methane gas into the atmosphere and causing the ice to thaw even more quickly.
