Climbers in Siberia have discovered the mummified paw of a mystery creature thought to have walked the earth thousands of years ago.
Scientists are carrying out tests to see if it belonged to a yeti!
Nobody has ever had proof that they exist, but loads of people believe the hairy creature is real.
Found in the mountains
The paw was found 3,500 metres up in the mountains in Russia's remote Siberia region.
The climber who found it said: "I turned the limb over and examined the sole of the foot, and I thought it looked unusual, so I decided to bring it back with me."
