Blade Technology Characterizing the MIS 5 D-A Layers of Sibudu Cave, South Africa

Abstract

ABSTRACTBlade technology, long associated solely with the Upper Paleolithic (UP) as an indicator of modern behavior, appears as early as the Middle Pleistocene and is present during the Middle Paleolithic (MP) and the Middle Stone Age (MSA). The nature behind the appearance of early laminar assemblages remains poorly understood. Yet current excavations at Sibudu Cave (KwaZulu-Natal, South Africa) have yielded MIS 5 lithic assemblages that contribute to the understanding of the diversity of blade technologies during the MSA. Following the chaîne opératoire approach, we explain how the knappers at Sibudu developed a laminar reduction strategy characterized by unidirectional cores with a lateral crest opposite a flat surface. The core configuration facilitated the production of blades with different intended morphological characteristics. Our results highlight the distinctiveness of the laminar reduction system of the D-A layers and foster the discussion on the role of this technological choice within the Southern African MSA.
