POLLEN, PHYTOLlTH, AND PROTEIN RESIDUE ANALYSIS FOR SITES 42WS4113 AND 42WS4115,UTAH

Pollen, phytolith, and protein residue samples were recovered from Sites 42Ws4115
and 42Ws4113 in southwest Utah. These sites represent artifact scatters containing lithic tools,
groundstone, and debitage. A mano from 42Ws4115 was washed to recover pollen, starches,
and phytoliths to determine plant resources that might have been processed using the mano. A
soil control in the vicinity of the mano and a general site soil control also were examined. A
projectile point fragment from 42Ws4115 and a projectile point base from 42Ws4113 were
analyzed for possible protein residues to provide information concerning animals that might
have been hunted/processed with these tools.

研究人员从犹他州西南部的42Ws4115与42Ws4113遗址中获取了花粉（Pollen）、植硅体（phytolith）与蛋白质残留（protein residue）样品。上述两处遗址均为包含石制工具（lithic tools）、磨制石器（groundstone）与石片废料（debitage）的遗物散布点（artifact scatters）。针对42Ws4115遗址出土的一件手持研磨石（mano），研究人员通过清洗操作提取其中的花粉、淀粉（starches）与植硅体，以推断该研磨石曾加工处理的植物资源类型。此外，研究人员还对该研磨石周边的土壤对照样品（soil control）以及遗址的普通土壤对照样品进行了检测分析。针对42Ws4115遗址出土的一件投射尖状器（projectile point）碎片与42Ws4113遗址出土的一件投射尖状器基部，研究人员开展了蛋白质残留检测，以获取这些工具曾用于猎杀或加工的动物相关信息。
