MACROFLORAL ANALYSIS AND AMS RADIOCARBON DATING OF CHARCOAL FROM FEATURE FILL AT SITE 48CO3511, CONVERSE COUNTY, WYOMING

Fill from a hearth at Site 48CO3511 was submitted for macrofloral analysis and AMS radiocarbon dating. It is believed that the site represents a Late Prehistoric occupation, possibly from 900-550 BP or as late as 100 BP with Middle Late Prehistoric artifacts in the vicinity. Macrofloral analysis will identify possible plant resources utilized, and a radiocarbon date will help classify the use period of the hearth feature and the site.

编号48CO3511遗址内一处火塘的堆积遗存已提交开展大植物遗存（macrofloral）分析与加速器质谱（Accelerator Mass Spectrometry, AMS）放射性碳定年。学界普遍认为该遗址属于晚史前时期的人类居留遗存，年代大致为距今900至550年，最晚可至距今100年，且遗址周边分布有中晚史前时期的人工遗物。大植物遗存分析将明确该遗址先民曾利用的潜在植物资源，而放射性碳定年结果则有助于界定该火塘遗存及整个遗址的使用时段。
