A site of Middle Palaeolithic occupation in the southern Nile Valley of Egypt in the Second Cataract. It has given its name to the final phase of the Nubian 'Middle Stone Age' for other sites close to the River Nile and contemporary with, or following, the Aterian. The site had Levallois flakes, denticulates, and burins. It seems probable that the Khormusan industry was broadly contemporary with the Dabban of Cyrenaica, belonging to the period following c 40,000 BC when increased aridity rendered the Sahara uninhabitable. Faunal remains from Khormusan sites indicate fishing and the hunting of land animals.
