- The nature of Nubian: developing current global perspectives on Nubian Levallois technology and the Nubian complexPublication . Hallinan, Emily; Barzilai, Omry; Beshkani, Amir; Cascalheira, João; Demidenko, Yuri E.; Goder‐Goldberger, Mae; Hilbert, Yamandú H.; Hovers, Erella; Marks, Anthony E.; Nymark, Andreas; Olszewski, Deborah I.; Oron, Maya; Rose, Jeffrey I.; Shaw, Matthew; Usik, Vitaly I.Nubian Levallois technology has recently risen to the forefront ofdebates surrounding Late Pleistocene human technological behavior,cultural traditions, and demographic histories. Named after the regionwhere it was first identified, Nubian Levallois describes a specificmethod of lithic point production that occurs in Middle Palaeolithic (or Middle Stone Age) assemblages across arid North Africa, the Levant and Arabia.1–9However, the recent identification of Nubian technology in separate, disconnected regions, such as SouthAfrica10–12and possibly India13,14suggests there are more diversescenarios of its emergence and spread than the original model of abroad Nubian technocomplex related to a single, expandingpopulation from its north‐east African heartland.3While fewassemblages containing Nubian technology are directly dated, itsproposed MIS 5 timing coincides with early modern human dispersalsout of Africa, adding a further dimension of whether certain lithictechnologies can be linked to specific geographic populations.
- A worked bone assemblage from 120,000–90,000 year old deposits at Contrebandiers Cave, Atlantic Coast, MoroccoPublication . Hallett, Emily Y.; Marean, Curtis W.; Steele, Teresa E.; Álvarez-Fernández, Esteban; Jacobs, Zenobia; Cerasoni, Jacopo Niccolò; Aldeias, Vera; Scerri, Eleanor M.L.; Olszewski, Deborah I.; El Hajraoui, Mohamed Abdeljalil; Dibble, Harold L.The emergence of Homo sapiens in Pleistocene Africa is associated with a pro found reconfiguration of technology. Symbolic expression and personal orna mentation, new tool forms, and regional technological traditions are widely recognized as the earliest indicators of complex culture and cognition in humans. Here we describe a bone tool tradition from Contrebandiers Cave on the Atlantic coast of Morocco, dated between 120,000–90,000 years ago. The bone tools were produced for different activities, including likely leather and fur working, and were found in association with carnivore remains that were possibly skinned for fur. A cetacean tooth tip bears what is likely a combination of anthropogenic and non-anthropogenic modification and shows the use of a marine mammal tooth by early humans. The evidence from Contrebandiers Cave demonstrates that the pan-African emergence of complex culture included the use of multiple and diverse materials for specialized tool manufacture.
