added by archaeologs A stone tool culture characterized by small backed bladelets and found across the North African coast from at least 22,000-10,000 years ago (the late Würm (last) glacial period). It followed the Aterian in the Epipalaeolithic of Maghreb in North Africa and preceded the Capsian. The culture was related to Cro-Magnon, a group of people known as the Mechta-el-Arbi race, living along the Mediterranean from Tunisia to Morocco and also Libya. Linked to the sea, there are huge shell mounds of mussels, oysters, and arca. Associated with these are pottery and limited stone tool industry, in conjunction with hearths, sometimes still marked by supporting stones. Extensive cemeteries have been investigated, as at Taforalt, and also at Afalou bou Rhummel and Columnata in Algeria. Burials were sometimes decorated with ochre or accompanied by food remains or by horns of wild cattle. The industry does bear a close resemblance to the late Magdalenian culture in Spain, which is broadly contemporary (c 15,000 BC). There is evidence suggesting that the Ibero-Maurusian industry is derived from a Nile River valley culture known as Halfan, which dates from c 17,000 BC.
