Researchers have shed light on the final centuries of the woolly rhinoceros after studying a hairy lump of meat from the stomach of an ancient wolf cub that became mummified in the Siberian permafrost.
The beautifully preserved remains of a two-month-old female wolf cub were discovered in 2011 near the village of Tumat in northeastern Siberia. The animal is thought to have died 14,400 years ago when a landslide collapsed its den, trapping the cub and others inside.
