Excavations at a complex of caves and open air sites at Pinnacle Point, Mossel Bay, Southern Africa have uncovered rich stratified assemblages of Middle Stone Age materials, including those from Pinnacle Point Cave 13B (PP13B) that comprises the first modernly excavated assemblage in southern Africa to be securely dated to the Middle Pleistocene. We report here on the complete excavated lithic artifact assemblage from PP13B. Both technological and typological analyses of the complete assemblage were performed. The assemblage-scale analysis allows for intrasite comparison as well as comparison of the PP13B assemblage with other sites from the region. No size-related pattern of change over time was observed within the PP13B assemblage, although there is significant evidence for varying strategies of lithic reduction between excavation areas within the cave. Comparison with other material from the Southern African MSA suggests that there is significant inter- and intra-site variability in the Southern African Middle Stone Age, even between portions of assemblages that are roughly contemporaneous.
在南非莫塞尔湾的尖峰点（Pinnacle Point）的洞穴和露天遗址群的挖掘工作中，发现了丰富的中石器时代物质的分层组合，其中包括来自尖峰点洞 13B（PP13B）的物质，这是南非第一个经过安全年代测定可追溯到中更新世的现代挖掘组合。我们在这里报告了来自 PP13B 的完整挖掘石器人工制品组合。对完整组合进行了技术和类型分析。在遗址内进行了组合规模分析，以便进行内部比较，以及将 PP13B 组合与该地区的其他遗址进行比较。虽然在洞穴内的挖掘区域之间存在明显的石器减少策略变化的证据，但在 PP13B 组合中没有观察到随时间变化的与尺寸相关的模式。与来自南非 MSA 的其他材料的比较表明，即使是大致同时的组合部分之间，南非中石器时代也存在显著的内部和内部之间的变异性。
