In this paper, we present the results of new archaeological and geological research carried out in SHK Extension, a new site excavatedwithin the SHK fluvial complex (Bed II, Olduvai Gorge). The paper describes the stratigraphy of the site and its correlation with our excavation in SHK Main Site, showing that overbank archaeological accumulations in both areas are synchronous and form part of the same fluvial palaeo-landscape. On the basis of the archaeostratigraphical analysis performed, mainly geared towards defining high-resolution chrono-stratigraphical frameworks within the deposit, we report the results of a technological study of the lithic collection sorted by archaeo-units, an assessment of the integrity of the main accumulation and an exhaustive lithic refitting programme. The archaeological sequence at SHK Extension, consisting of three archaeo-units, preserves a high-density patch of lithics and fossil bones (Level B2), on an overbank setting, isochronous with the SHK Main site. The high percentage of small lithic remains and bones, large number of fresh archaeological materials, and the identification of several refit sets support the integrity of the anthropogenic accumulation documented in Level B2. The main technological trait of the lithic assemblage from this level is the preservation of a qualitatively significant sample of large flakes and LCTs. The technological behaviours observed in SHKE, in the frameworkof the SHK complex, confirm that the complex web of inter-assemblage variability during Bed II times operated also in very close fractions of the same palaeo-landscape. This reinforces the idea that subtle functional parameters must be taken into account in our current assessment of the Developed Oldowan/Acheulean interface.Fernando Diez-Mart ın (fernando.diez.martin@uva.es),

Both the form of a stone tool and the anatomy of the individual using it have potential to influence its cutting performance. To date, however, the selective pressures acting on stonetool form and hominin biometric/biomechanical attributes have been investigated in isolation and their relative influence on performance have never been compared directly. This paper examines the influence of both tool-form attributes and biometric variation on the functional performance of Acheulean handaxes. Specifically, it investigates the impact of 13 tool attributes and eight biometric traits on the working forces applied through the edge of 457 replica tools. The relative contribution of tool-form and biometric attributes to handaxe loading levels were examined statistically. Results identify that both tool-form attributes and biometric traits are significantly related to loading; however, tool-user biometric variation has a substantially greater impact relative to tool-form attributes. This difference was demonstrated by up to a factor of 10. These results bear directly on the co-evolutionary relationships of stone tools and hominin anatomy, and the comparative strength of selective pressure acting on each. They also underline why handaxe forms may have been free to vary in form across time and space without necessarily incurring critical impacts on their functional capabilities.

Core preparation has been documented in Developed Oldowan assemblages dated between 1.5–1.3 Ma. However, its correct identification and significance is a matter of debate. In order to shed light on this issue, this paper attempts to reconstruct the flake production processes of the lithic assemblages currently recovered in SHK and BK at Olduvai Gorge (Tanzania). The methodological approach applied for the study of these two classical Developed Oldowan sites is based on the analysis and classification of flaking cores through detailed diacritical and technological descriptions, regardless of aprioristic morphological considerations. The flake production processes identified in both assemblages exhibit great technological homogeneity. The most remarkable difference between them is linked with divergences in flake size production. Core rotation and elongation of the perimeter of the flaked surface were the main technical actions implemented to manage core reduction, and seem to be related to reduction intensity. Core preparation, specifically striking platform preparation, was also applied, but to a minor extent, and was linked with a more effective management of blank reduction. It was not carried out through rigid technical and geometric schemes, and the products obtained were not predetermined. Nevertheless, its mere presence in Developed Oldowan sites is very suggestive, as it confirms a strong relationship between the Developed Oldowan and early Acheulean assemblages.
