A woolly mammoth calf carcass was recently discovered by a reindeer herder in the Russian Arctic. The 40,000-year-old calf carcass was protruding from the permafrost in Arctic Yamalo-Nentsk region. Though the mammoth’s coat is gone, its skin and internal organs are intact, making the find an exceptional one. Woolly mammoths have been extinct since the Earth’s last ice age, between 1.8 million and 11,500 years ago. At one time they walked alongside the humans, Neanderthals and Denisovans.
