摘要类型学交叉年代测定是将考古遗址纳入年代框架的主要手段。这种方法依赖于这样的假设，即在未注明日期的网站，通常是弹丸点的文物是同时代的类似文物发现在其他，日期的网站。虽然类型交叉定年是必要的，在以露天碎石分散为主的地区，这种方法可能是有问题的，当未注明日期和日期的网站是由显着的距离分开。在这里，我们提出了放射性碳年代的投射点与有机hafting材料仍然附着或发现在有机存储袋。我们的研究结果提供了明确的年龄在几个大盆地地区的各种形态抛射点类型，应该是有用的研究人员寻求当地的年龄估计这些点类型，这往往涉及依赖于更遥远的网站的年代数据。研究结果还突出了不加批判地使用基于度量属性的类型学进行类型交叉定年的潜在问题，在两种情况下，建议需要修改西部大盆地某些点样式的年龄范围。
Abstract Typological cross-dating is the primary means by which archaeological sites are placed into chronological frameworks. This approach relies on the assumption that artifacts at undated sites—usually projectile points—are coeval with similar artifacts found at Other, dated sites. While typological cross-dating is necessary in regions dominated by open-air lithic scatters, the approach can be problematic when undated and dated sites are separated by significant distances. Here, we present radiocarbon dates on projectile points with organic hafting material still attached or found within organic storage bags. Our results provide unequivocal ages for various morphological projectile point types at several Great Basin locales and should be useful to researchers seeking local age estimates for those point types, which often involves relying on chronological data from more distant sites. The results also highlight potential issues with uncritically applying typological cross-dating using typologies based on metric attributes, and in two cases, suggest the need to revise the age ranges for certain point styles in the western Great Basin.
