AMS RADIOCARBON DATING AND PHYTOLITH AND STARCH GRAIN ANALYSIS OF ORGANIC RESIDUE FROM A BESANT PHASE POTSHERD, MAINARD RANCH, 24LT505, MONTANA

A Besant phase potsherd with visible residue from site 24LT505 was submitted for AMS radiocarbon dating and phytolith and starch grain analysis. Radiocarbon dating the charred residue provides information on when the vessel represented by this sherd was primarily in use. Phytolith and starch grain analysis provides information on some of the foods prepared or stored within the vessel.一件采自遗址24LT505、带有可见残留物的贝桑特期（Besant phase）陶片，被送检以开展加速器质谱仪放射性碳定年法（AMS radiocarbon dating）、植硅体（phytolith）与淀粉粒分析。对该炭化残留物进行放射性碳定年，可获取此陶片所代表的陶器的主要使用时段信息。植硅体与淀粉粒分析则能够揭示该容器内曾制备或储存的部分食物品类。
