In the 1970s and 1980s, the emergence of the Acheulean at Melka Kunture (Upper Awash, Ethiopia) was dated to 1 Ma (million years ago), based on the typo-metrical analysis of the lithic assemblage of Garba Xlfi. Older sites such as Gombore I, Karre I, and Garba IV (1.7-1.5 Ma) were classified as Oldowan/Developed Oldowan. Consequently, the Oldowan and the Acheulean at Melka Kunture were interpreted as two distinct technologies separated by a chronological gap of 0.5 Ma. The archaeostratigraphic unit D of Garba IV, dated to similar to 1.5 Ma, yielded one of the richest Early Stone Age lithic series in East Africa. In this paper, a review traces methods of technological analysis, based on the concept of chaine operatoire, to update our knowledge of the techno-economic behaviours at this site. The results show two major elements characteristic of cultural changes in the Melka Kunture sequence: (1) the emergence of a new chaine operatoire focused on large flake/large cutting tool (LCT) production, and (2) a large variability of small debitage modalities with systematic preparation of the striking platform and the appearance of a certain degree of predetermination. These technological traits are shared by the contemporaneous sites in East Africa and are considered to be typical of the early Acheulean. This suggests an older origin for the Acheulean at Melka Kunture, 0.5 Ma than previously inferred. (C) 2013 Elsevier Ltd. All rights reserved.
