PHYTOLITH AND STARCH ANALYSIS OF FEATURE FILL SAMPLES FROM THE PINTO SITE (48CR10382), CARBON COUNTY, WYOMING

The Pinto site (48CR10382) is located in the eastern portion of the Washakie Basin in Carbon County, south central Wyoming. Excavations have exposed thermal basins, a housepit feature, and associated artifacts at this multi-occupational hunter-gatherer site. Two components identified at the site produced radiocarbon dates between 4810–5100 BP (Component I) and 5510–5540 BP (Component II) (Susan Murray, personal communication December 3, 2014). Fill from four pit features were submitted for phytolith and starch analysis in search of evidence of economic activity.

平托遗址（Pinto site，编号48CR10382）坐落于怀俄明州中南部卡本县所辖的沃夏基盆地东部区域。该遗址为一处多期居留的狩猎采集遗址，经考古发掘揭露有热灶坑遗迹、房坑遗迹以及相关伴随出土遗物。遗址内识别出两个文化堆积组分，经碳十四测年，其年代分别为距今4810~5100年（组分I）与距今5510~5540年（组分II）（苏珊·默里，2014年12月3日私人通信）。本次研究选取4处坑遗迹的填土开展植硅体（phytolith）与淀粉粒分析，以探寻该遗址古人类生业活动的相关证据。
