Bizarre video footage shows stones discovered by archaeologist Chi Pu Tei back in 1937 when he was trying to find shelter in the Kunlun-Kette mountains of China.
Team members entered the caves and discovered inscriptions on the walls.
At the back of the cave, they uncovered several tombs, aligned in a row, containing strange looking skeletons, each no larger than one metre in length.
Buried alongside them were more than 700 unusual discs covered in unexplainable artwork.
