The rock art of the Djelfa region shows large naturalistic cattle (Zaccar) and sub-naturalistic ones (Bou Sekkin), the others dating from the pastoral era. Their horns are similarly closed into a ring and they sometimes wear devices in segments of a circle, or of textile, which are perhaps means of carrying things (Hadjra Sidi Boubakeur, Teniet el Mzab, Hadjra Mohkotma, Ben Hadid, Bou Sekkin, Safiet bou Khenan and Oued Mergueb).
