POLLEN AND MACROFLORAL ANALYSIS AT THE NOMAD SITE, 48SW9204, SOUTHWEST WYOMING

The floated light fractions from the fill of five basin hearth features at the Nomad site,
48SW9204, in southwest Wyoming were examined for macrofloral remains to provide information
concerning plant resources that were utilized by the site occupants. In addition, a mano fragment
found on the edge of a small pit of unknown function (Feature 6) was washed for pollen and
starches to determine plants that might have been ground using the mano. A soil control was
collected with the mano. Feature 6 has yielded an uncalibrated radiocarbon age of 4740 ± 80 BP,
indicating an Archaic occupation of the site.

对怀俄明州西南部48SW9204号Nomad遗址5处盆形火塘遗迹充填物的浮选轻组分开展大植物遗存分析，以获取该遗址先民所利用植物资源的相关信息。此外，针对在功能不明的小型坑穴（6号遗迹）边缘发现的1件手磨残块，通过水洗流程提取花粉与淀粉粒，以此推断曾使用该手磨加工的植物种类。研究过程中同步采集了与该手磨残块伴存的土壤对照样品。6号遗迹的未校正放射性碳测年结果为4740±80 BP，表明该遗址存在古风时期的人居活动。
