Schoolgirl stumbles upon oldest known lemming preserved in permafrost

A schoolgirl has found a 41,000-year-old lemming preserved in the Siberian permafrost.

Angelina Sadovnikova, then aged 11, came across the mummified rodent under a river cliff.

Angela is now 14 but the discovery has just been revealed after a scientific investigation.

She was with her mum at the Tirekhtyakh River, close to the Arctic Circle, when she spotted the carcass.

Radiocarbon dating has revealed the Siberian brown lemming to be 41,300 years old.
