Abstract

ABSTRACT The Pilauco site, in northwestern Chilean Patagonia, presents evidence of human occupation in South America ca. 16,500 cal yr BP. This article presents the techno-functional analysis of a unifacial artifact belonging to a 17,300 cal yr BP level, found in association with five other lithic pieces. Artifacts of this type have long been considered expedient rather than formal or curated pieces. These artifacts remain in the shadow of bifacial pieces, particularly so-called projectile points. The results of the techno-functional analysis made it possible to diagnose the unifacial artifact as a plano-convex volumetric structure with two parallel backs, on which two different tools were produced at different manufacturing stages via the technical operations of affordance, debitage, and shaping. The detailed description of this type of artifact is crucial for a more complete definition of the technical phenomena associated with the first occupations in South America.

超越强大的抛射点:一件晚更新世器物的技术功能研究，皮劳科遗址，Osorno，智利西北部巴塔哥尼亚

摘要位于智利巴塔哥尼亚西北部的皮劳科遗址提供了南美洲约16500 cal yr BP人类占领的证据。本文介绍了一件属于17300卡年BP水平的单面文物的技术功能分析，该文物与其他五件石器碎片有关。长期以来，这类文物一直被认为是权宜之计，而不是正式或精心策划的作品。这些人工制品仍然存在于双面碎片的阴影中，特别是所谓的投射点。技术功能分析的结果使得将单面伪影诊断为具有两个平行背的平凸体积结构成为可能，在该结构上，通过可供性、借记和成型的技术操作，在不同的制造阶段生产了两种不同的工具。对这类人工制品的详细描述对于更完整地定义与南美洲第一批职业相关的技术现象至关重要。
