kya Horse Period, roughly 3-2 kya Camel Period, 2,000 years ago to the present Works of the Bubalus period span the Sahara, with the finest work, carvings of naturalistically depicted megafauna, concentrated in the central highlands. The Round Head Period is dominated by paintings of strangely shaped human forms, and few animals, suggesting the artists were foragers.These artists may have been producing rock art 2,000 years before domestication. These works are largely limited to Tassili n'Ajjer and the Tadrart Acacus. Some works show figures with bows near herds of cattle and a reunion of members near cattle. Round heads are found in Tassili, Jebel Uweinat and Ennedi, which may indicate similar cultures between these populations. Other animals represented in the Round head art are hippopotamus, elephant, and bovids. Animals like antelope and mouflon are also represented; fauna remains have been found in archaeological sites during excavations. About 90% of Round Head art is animal representation. Toward the end of the period, images of domesticated animals, as well as decorative clothing and headdresses appear. Some domesticated animals are cattle from the Bovidae family. Pastoral Period art was more focused on domestic scenes, including herding and dancing. As well as hunting scenes of mouflon. Unlike in the Round Head art, the bow is relevant to Pastoral art since hunting scenes were depicted during this time. Pastoral figures are seen on the same wall of Round Heads except they are along the borders. The foragers may have been respecting the previous artwork and did not paint over the figures. The quality of artwork declined, as figures became more simplified. The Horse Period began in the eastern Sahara and spread west. Depictions from this period include carvings and paintings of horses, chariots, and warriors with metal weapons, although there are also frequent depictions of wildlife such as giraffes. Humans are generally depicted in a stylized way. Some of the chariot art bears resemblance to temple carvings from ancient Egypt. Occasionally, art panels are accompanied by Tifinagh script, still in use by the Berber people and the Tuareg today; however, modern Tuareg are generally unable to read these inscriptions. The final Camel period features carvings and paintings in which camels predominate, but also include humans with swords, and later, guns; the art of this time is relatively crude.
