Rock art
human-made markings on natural stone / From Wikipedia, the free encyclopedia
Rock art is a term in archaeology for any markings that were made on natural stone by human beings.[1] They can be divided into:
- Petroglyphs – carvings into stone surfaces
- Pictographs – rock and cave paintings
In addition, there is rock art made by aligning or piling natural stones. The stones themselves are used as large markings on the ground.
