Since the discovery, scientists have recovered part of the animal’s skull, the lower jaw, several ribs, and a foot fragment with sinews still intact.
The plan is to create a woolly mammoth-elephant hybrid.

The animals could play a key role in slowing climate change.
The extinct creature is believed to have roamed the Earth between 10,000 and 15,000 years ago.
