The extreme cold preserved some of the male mammoth's soft tissue, including the remains of its fat hump and its penis, they said.
However, injuries found on the mammoth's bones — including its ribs, left shoulder bone, right tusk and cheekbone — suggest that it had a violent end.
Some of the bones have dents and punctures, possibly from thrusting spears, the researchers said.
"[These injuries] are clearly related to the death of the animal, which was killed and then partly butchered," Pitulko said in a statement he emailed to journalists.
The slashed and punctured bones of a woolly mammoth suggest that humans lived in the far northern reaches of Siberia earlier than scientists had previously thought, a new study finds.
Before the surprising discovery, researchers thought that humans lived in the freezing Siberian Arctic no earlier than about 30,000 to 35,000 years ago.
