T1 Diversity and significance of core preparation in the Developed Oldowan technology: reconstructing the flaking processes at SHK and BK (Middle-Upper Bed II, Olduvai Gorge, Tanzania)

AB 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 paperattempts to reconstruct the flake production processes of the lithic assemblages currently recovered in SHK andBK at Olduvai Gorge (Tanzania). The methodological approach applied for the study of these two classical DevelopedOldowan sites is based on the analysis and classification of flaking cores through detailed diacritical andtechnological descriptions, regardless of aprioristic morphological considerations. The flake production processesidentified in both assemblages exhibit great technological homogeneity. The most remarkable difference betweenthem is linked with divergences in flake size production. Core rotation and elongation of the perimeter of theflaked surface were the main technical actions implemented to manage core reduction, and seem to be related toreduction intensity. Core preparation, specifically striking platform preparation, was also applied, but to a minorextent, and was linked with a more effective management of blank reduction. It was not carried out through rigidtechnical and geometric schemes, and the products obtained were not predetermined. Nevertheless, its mere presencein Developed Oldowan sites is very suggestive, as it confirms a strong relationship between the DevelopedOldowan and early Acheulean assemblages.
