Abstract

ABSTRACT Triangular non-stemmed points (TNSPs) have been recovered for several decades from early archaeological sites in different regions of South America. We report a synthesis and review of 63 early Holocene radiocarbon dates (∼12,650–8050 cal yr BP) of the main sites where TNSPs have been recovered and records of this point design with fluting technology. The oldest ages of dated sites with TNSPs are synchronous with ages obtained for Fishtail point sites. The extra-regional evidence allows discussion of aspects related to the use of open environments, chronology, size, context, fluting technology and distribution of these points, leading to the generation of new ways to continue increasing our understanding of cultural complexity in early settlement in South America. The results open new perspectives and implications for the debate on social interaction and technological transmission by Paleoamericans during the peopling of South America.

乌拉圭的凹槽三角形无茎点及其区域外关系:南美洲全新世早期技术多样性的扩大

几十年来，在南美洲不同地区的早期考古遗址中发现了三角形无茎点(TNSPs)。我们报告了63个早全新世放射性碳年代(~ 12,650-8050 calyr BP)的综合和回顾，这些地点已经恢复了tnsp，并记录了这种点设计的fluting技术。具有TNSPs的测年站点的最古老年龄与鱼尾点站点的年龄同步。区域外的证据允许讨论与开放环境的使用、年代、大小、背景、长笛技术和这些点的分布有关的方面，从而产生新的方法，继续增加我们对南美洲早期定居文化复杂性的理解。这一研究结果为南美洲人类定居期间古美洲人的社会互动和技术传播的争论开辟了新的视角和意义。

期刊介绍： PaleoAmerica disseminates new research results and ideas about early human dispersal and migrations, with a particular focus on the Americas. It fosters an interdisciplinary dialog between archaeologists, geneticists and other scientists investigating the dispersal of modern humans during the late Pleistocene. The journal has three goals: First and foremost, the journal is a vehicle for the presentation of new research results. Second, it includes editorials on special topics written by leaders in the field. Third, the journal solicits essays covering current debates in the field, the state of research in relevant disciplines, and summaries of new research findings in a particular region, for example Beringia, the Eastern Seaboard or the Southern Cone of South America. Although the journal’s focus is the peopling of the Americas, editorials and research essays also highlight the investigation of early human colonization of empty lands in other areas of the world. As techniques are developing so rapidly, work in other regions can be very relevant to the Americas, so the journal will publish research relating to other regions which has relevance to research on the Americas.
