Three different types of engravings can be distinguished at Twyfelfontein: iconic imagery (images of animals, humans, and fantasy creatures); pictograms (geometric rock art like pecked circles, rows of dots); indentations for or from everyday use (grinding hollows, board games, gong stones). The hunter-gatherers made most of the iconic engravings and probably all the paintings. The carvings represent animals such as rhinoceroses, elephants, ostriches and giraffes as well as depictions of human and animal footprints.
