Abstract

ABSTRACT The Spring Lake Site (41HY160) in San Marcos, located along the Balcones Escarpment in central Texas, produced fluted points that appear diagnostic of Clovis technology as well as ice-age megafauna remains. Unfortunately, these materials were recovered in what appears to be mixed deposits within the lake itself. For over 40 years, researchers have hypothesized that the points represent Clovis technology and presence at the site. We use a two-dimensional landmark approach to geometric morphometric shape analysis to test the typological context of the artifacts against a dataset of well-dated Clovis point specimens. We examine whether they fall within a morphological range of variation in planview shape documented in point assemblages from Clovis sites organized geographically into the Southwest, Northwest, and Northeast regions. Results suggest that the Spring Lake points possess particular affinity in shape to Clovis points found in the Southwest region.

德克萨斯州斯普林湖长笛点的评价：三叶草亲和性的几何形态分析

摘要：位于得克萨斯州中部巴尔科内斯悬崖沿岸的圣马科斯泉湖遗址（41HY160）产生了凹槽点，这些凹槽点似乎是克洛维斯技术的诊断，也是冰河时期巨型动物群的遗迹。不幸的是，这些物质是在湖泊内部的混合沉积物中回收的。40多年来，研究人员一直假设这些点代表了Clovis的技术和现场的存在。我们使用二维标志性方法进行几何形态计量形状分析，以根据年代久远的克洛维斯点标本数据集测试文物的类型背景。我们研究了它们是否属于平面图形状变化的形态学范围，这些变化记录在地理上分为西南、西北和东北地区的克洛维斯遗址的点组合中。结果表明，泉湖点在形状上与西南地区的克洛维斯点具有特殊的亲和力。

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.
