Scientists in Russia are preparing to clone a 42,000-year-old horse. The perfectly preserved baby horse was discovered last year in the Batagaika Crater in eastern Siberia.
The incredible discovery also contained an unexpected surprise. Upon autopsy the horse was found to contain liquid blood; the oldest blood ever recorded.
Usually, blood coagulates or turns to powder as the liquids inside it ages. The liquid blood found in the horse's heart means there is the possibility of cloning the foal. But it won't be easy.
