An Early Iron Age group in northern Zambia, taking its name from the 4th century AD village at Kalambo Falls. It is of the Chifumbaze complex. A prepared-core industry existed by c 36,000 BC and a true backed microlith assemblage appeared by 20,000 BC. The shift to a microlithic industry was accompanied by a change in faunal remains indicating a new preference for hunting small solitary creatures. The site also contains a large series of rock paintings, probably of later Iron Age date.
