MACROFLORAL ANALYSIS AND AMS RADIOCARBON AGE DETERMINATION OF HEARTH FILL FROM SITE 48CO3688, LOCALITY 7608-5, CONVERSE COUNTY, WYOMING

Site 48CO3688 lies on the crest of a broad ridge in Converse County, Wyoming. A surface hearth contained fire-affected rock and one flake. No tools or diagnostic artifacts were associated with this site (John Greer, personal communication July 23, 2015). Feature fill from soil probes was submitted for macrofloral and AMS radiocarbon analysis to ascertain the period of occupation. Charcoal from this locality is expected to date between 2500 and 800 BP (John Greer, personal communication July 23, 2015).遗址48CO3688坐落于怀俄明州康弗斯县一处宽阔山脊的顶部。该遗址的地表火塘内出土有受火作用的岩石与1件石片，未关联出土工具或诊断性人工遗物（约翰·格里尔，2015年7月23日私人通信）。研究人员将土壤钻探获取的遗迹填充物送检，开展大植物遗存与加速器质谱（AMS）碳十四测年分析，以确定该遗址的人类居住时段。该地点出土的木炭测年结果预计介于距今2500年至800年之间（约翰·格里尔，2015年7月23日私人通信）。
