摘要

摘要：在佛罗里达州Alexon遗址发现的一头野牛头骨中嵌入的燧石物体被认为是美国东南部更新世末人类和巨型动物相互作用的直接证据。先前的分析表明，燧石物体是一个披针形抛射点的中段。来自两种不同野牛元素的未纯化野牛胶原蛋白的放射性碳年龄产生了更新世晚期和全新世早期。我们能够重新定位现场并检查地层，但我们对骨头进行放射性碳年代测定的尝试失败了。我们获得了微型计算机断层扫描，并使用数字成像软件生成嵌入对象的三维渲染图。最后，对头骨和嵌入的物体进行了目视检查。我们得出结论，嵌入头骨中的物体不是人工制品，Alexon遗址是一个古生物遗址。

A Reexamination of the Paleoindian Bison Kill at the Alexon Site, Florida

ABSTRACT A chert object embedded in the cranium of a bison found at the Alexon site, Florida, is cited as direct evidence of human and megafauna interaction at the end of the Pleistocene in the American Southeast. Previous analyses identified the chert object as the mid-section of a lanceolate projectile point. Radiocarbon ages on unpurified bison collagen from two separate bison elements yielded Late Pleistocene and Early Holocene ages. We were able to relocate the site and examine the stratigraphy, but our attempts to radiocarbon date the bone failed. We obtained micro-computed tomography scans and used digital imaging software to generate a three-dimensional rendering of the embedded object. Finally, the skull and embedded object were visually examined. We conclude that the object embedded in the skull is not an artifact and that the Alexon site is a paleontological locality.

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.
