A Neolithic culture of the Yenisei valley of southern Siberia. The people, who were stock breeders and hunters, probably moved into the area in the late 3rd millennium BC. Excavations uncovered burials under kurgans (low mounds), surrounded by circular stone walls. There was stamped dentate pottery, stone, bone, and bronze tools, and some copper ornaments with the burials. The Afanasievo people were the first food-producers in the area, breeding cattle, horses, and sheep, but also practiced hunting. The Afanasievo were succeeded by the Andronovo culture in the mid-2nd millennium BC.
