The remarkably well preserved frozen carcass was discovered in Siberia as part of a BBC/Discovery Channel-funded expedition and is believed to be at least 10,000 years old, if not older. If further study confirms the preliminary findings, it would be the first mammoth carcass revealing signs of human interaction in the region.The carcass is in such good shape that much of its flesh is still intact, retaining its pink color. The blonde-red hue of Yuka's woolly coat also remains.
