MACROFLORAL ANALYSIS AND AMS RADIOCARBON DATING OF HEARTH FILL FROM SITE 48CO3613, CONVERSE COUNTY, WYOMING

The small prehistoric Site 48CO3613, located in Converse County, Wyoming, is a lithic scatter with a surface-exposed open hearth feature. A small projectile point, recovered among the scattered flakes and tools, is believed to be a Late Archaic dart point from approximately 2000 BP (John Greer, personal communication November 16, 2014). Charcoal/ash-rich feature fill was collected from the hearth and submitted for macrofloral analysis and AMS radiocarbon dating.

位于美国怀俄明州康弗斯县的史前小型遗址48CO3613，是一处带有地表裸露露天火塘遗迹的石制品散布区。在散落的石片与工具中出土的一枚小型投射尖，被认为是距今约2000 BP的晚古风期镖尖（约翰·格里尔，2014年11月16日私人通讯）。研究人员从该火塘中采集了富含木炭与灰烬的遗迹填充物，并将其送检开展大植物遗存分析与加速器质谱（AMS）碳十四测年。
