[3][4] Similarly, the Blombos Cave of South Africa yielded some stones with engraved grid or cross-hatch patterns, dated to some 73,000 years ago, but they are attributed to Homo sapiens.
[2] In July 2021, scientists reported the discovery of a bone carving, one of the world's oldest works of art, made by Neanderthals about 51,000 years ago.
The "Divje Babe flute" had controversially been claimed as a Neanderthal musical instrument, though many researchers believe that its holes are most likely the bite marks of carnivores.
[11][12] In 2002 in Blombos cave, situated in South Africa, ochre stones were discovered engraved with grid or cross-hatch patterns, dated to some 70,000 years ago.
The interpretation of the hatching patterns as "symbolic" has been challenged, and several purely functional explanations of the objects have been proposed, e.g. as an ingredient in mastic, skin protection against sun or insects, as soft-hammers for delicate knapping, as a hide preservative or as medicine.
