Hammer or crescent wrench? Stone-tool form and function in the Aurignacian of southwest Germany

Abstract

The early Upper Paleolithic of Europe is associated with the appearance of blade/bladelet technology (e.g., Aurignacian). These industries include a wider range of formal tool types than seen in the Middle Paleolithic. Greater diversity in tool types is often interpreted as specialized tools created for specific tasks. This, in turn, is said to reflect dramatic behavioral shifts between Neandertals and modern humans. In order to test previous interpretations, it is necessary to have a detailed understanding of early Upper Paleolithic stone-tool function. Toward this end, analyses of microscopic residue and use-wear were undertaken on 109 stone tools from three Aurignacian sites in southwest Germany (Hohle Fels, Geißenklösterle, and Vogelherd). These cave sites evidenced remarkable residue preservation, with approximately 82% of the sample showing some form of functional evidence. Residues observed included hair, feathers, bone/antler, wood, plant tissue, phytoliths, starch grains, and resin. The results suggest that tool typology is not strongly linked to the processing of specific materials. For example, endscrapers from the sample show evidence of processing wood, charred wood, plants, starchy plants, birds, bone/antler, and animals (hair). Hairs are found on tools typologically classified as blades, flakes, borers, pointed blades, and combination tools (nosed endscraper-borer, burin-laterally-retouched blade). In the early Upper Paleolithic of southwest Germany, a wide range of tool types appears to have been used to process a diverse array of materials. These results suggest that the interpretation of behavioral patterns from stone tools must consider more than tool typology. © 2007 Elsevier Ltd. All rights reserved.
