Lithic Economy and Specialized Activities Among the Iberomaurusian Populations of Tamar Hat Rockshelter (Northeastern Algeria)

Tamar Hat rockshelter (Béjaïa, northeastern Algeria) has yielded a lithic assemblage showing general characteristics of an Iberomaurusian Early Late Stone Age nature. Specific “becs,” which we shall call “becs of Tamar Hat,” appear as an important component of the assemblage in the upper occupations, which occurred at the end of Late Glacial Maximum. These becs, from a technological point of view and especially by their shaping processes, constitute a reliable reference collection, though showing morphological variability resulting in part to the reduction process. The use-wear analysis conducted, based on a microscopic examination validated by experimentation, testifies the becs would have functioned for engraving hard bone, such as those of deer. Other scars observed on the sharp edge and lower face near the active portion of the tool are caused by hafting. Hence, the results of the technological and functional analyses of the becs from Tamar Hat reveal the presence of specialized activities in the upper occupations, related to the animal bone processing. These results are supported by the archaeozoological study, which confirms that the site functioned as a seasonal habitat, where Megacerin deer was exploited in the upper occupations for utilitarian, non-food purposes. The emergence of the use of the becs of Tamar Hat is synchronous with the end of the Upper Paleolithic, prior to the expansion of bec use in the Upper Magdalenian of Europe, where technical and stylistic convergences were observed. This raises the question of the emergence of these lithic implements in North Africa and the possible spread of similar industries elsewhere.
