Abstract

Recent fieldwork at SHK Main site and SHK Extension (2009–2016) has recovered an abundant lithic sample that contains giant cores, large flakes and large cutting tools (LCT), such as bifaces, cleavers, picks and knives. Such a significant collection constitutes an opportunity to understand and reconstruct the chaîne opératoire of LCT production undertaken by hominins at this site complex. Through a technological approach based on detailed reconstructions of the large tool shaping patterns and the analysis of techno-functional potentiality, this work presents the study of lithic implements specifically related to the Acheulean sequence unearthed at SHK by our team. This assessment has been completed with other specimens identified by us among the original Leakey collections. The aim is to define the LCT conceptualization strategies of the SHK toolmakers. This information, in combination with subsequent experimental and use-wear analyses, will shed light on the functional meaning of the LCTs produced during the Early Acheulean.

来自SHK（床II， Olduvai峡谷，坦桑尼亚）的大型切削工具：一种技术功能方法

最近在新鸿基主场和新鸿基延伸区（2009-2016）的野外工作中，发现了大量的岩石样本，其中包含巨大的岩心、大薄片和大型切割工具（LCT），如双面刀、切刀、镐和刀。如此重要的收集提供了一个机会来理解和重建在这个遗址复合体中人类进行的LCT生产的cha ne opsamatoire。通过对大型工具成形模式的详细重建和技术功能潜力分析的技术方法，本工作介绍了我们团队在SHK出土的与阿舍利序列有关的石器工具的研究。这项评估已经与我们在原始的利基藏品中鉴定的其他标本一起完成。目的是定义香港工具制造商的LCT概念化策略。这些信息，结合随后的实验和使用磨损分析，将阐明早期阿舍利时期生产的lct的功能意义。

期刊介绍： Archaeological and Anthropological Sciences covers the full spectrum of natural scientific methods with an emphasis on the archaeological contexts and the questions being studied. It bridges the gap between archaeologists and natural scientists providing a forum to encourage the continued integration of scientific methodologies in archaeological research. Coverage in the journal includes: archaeology, geology/geophysical prospection, geoarchaeology, geochronology, palaeoanthropology, archaeozoology and archaeobotany, genetics and other biomolecules, material analysis and conservation science. The journal is endorsed by the German Society of Natural Scientific Archaeology and Archaeometry (GNAA), the Hellenic Society for Archaeometry (HSC), the Association of Italian Archaeometrists (AIAr) and the Society of Archaeological Sciences (SAS).
