(CNN)Found frozen deep in the Siberian Arctic, the cave lion cub looks like she’s asleep and one touch might awaken her. The cub’s golden fur is matted with mud but otherwise undamaged. Her teeth, skin, soft tissue and organs are mummified but all intact. Some 28,000 years since she last closed her eyes, her claws are still sharp enough to prick the finger of one of the scientists who are studying this remarkable — and unprecedented — permafrost-preserved specimen.
