Kamyana Mohyla is a rock art location in Southeastern Ukraine. This is the only one large rock art location in Ukraine. It contains prehistoric art pieces associated with the wast landmass from Central Europe to Western Mongolia. The site consists of 68 rock art locations and almost 400 portable rock art pieces, all engraved in the dense and heavy sandstone. Portable rock art specimens extracted by Valentin Danilenko from Churinga Cave in 1973—1974. There are no archaeological or stratigraphic context in the cave. However, based on the outlook of the figurines, the nature of the stones and the pecularities of the ornamentatioin, they were attributed to the Late Mesolithic of the region.
Dataset contains 30 portable rock art specimens (32 3D models) made of the hard sandstone and sometimes covered with shallow engravings on surface. Some of the stones represent fish figurines, others are amorphous
