Late Acheulean Handaxes from Northeastern Caucasus: Morphology and Technology

We describe the variability of morphological and technological features of handaxes from two culturally and chronologically consecutive Acheulean assemblages of Dagestan, Northeastern Caucasus. The early one, dating to MIS 11, 10 is represented by three sites: Darvagchay-Zaliv-1 (complex IV, layer 3), Darvagchay-Zaliv-4 (layer 5), and Darvagchay-Zaliv-2. The late complex, dating to MIS' 7, includes the sites of Darvagchay-Zaliv-1 (complex IV, layer 2), Darvagchay-Zaliv-4 (layer 3), and Darvagchay-Karier. We examine analogies from other Acheulean sites in the Caucasus. Two-dimensional geometric-morphometric analysis was used to study the shape of tools from Dagestan. The findings suggest that the shape of unifacial tools is the same as that of bifaces. The comparison of tools from two cultural and chronological horizons, including those from contemporaneous sites in the Caucasus, indicates a higher variability in earlier tools. Based on the scar pattern analysis, three chaises operatoires in manufacturing handaxes were reconstructed. Tools of the later complex had been subjected to a more thorough reduction than those of the early complex. Technological continuity was traced over a considerable tirnespan (MIS 11-7). it was manifested in the standardization of biftcial shape and the gradual sophistication of chaises operatoires. Given the high morphological homogeneity of tools from Dargvachay complexes and other contemporaneous industries of the Caucasus, it can he suggested that these technological tendencies are characteristic of the entire Caucasus.
