Halfan and Kubbaniyan culture

The Halfan and Kubbaniyan, two closely related industries, flourished along the Upper Nile Valley. Halfan sites are found in the far north of Sudan, whereas Kubbaniyan sites are found in Upper Egypt. For the Halfan, only four radiocarbon dates have been produced. Schild and Wendorf (2014) discard the earliest and latest as erratic and conclude that the Halfan existed c. 22.5-22.0 ka cal BP. People survived on a diet of large herd animals and the Khormusan tradition of fishing. Greater concentrations of artifacts indicate that they were not bound to seasonal wandering, but settled for longer periods. The Halfan culture was derived in turn from the Khormusan, which depended on specialized hunting, fishing, and collecting techniques for survival. The primary material remains of this culture are stone tools, flakes, and a multitude of rock paintings.
