POLLEN AND PROTEIN RESIDUE ANALYSIS OF SAMPLES FROM LITTLE SPRING CREEK, SITE 5RB3691, NORTHWESTERN COLORADO

Site 5RB3691 is located between the towns of Rangely and Meeker in western
Colorado and is believed to represent the late Archaic Period . Five pollen
samples were collected and analyzed from three pit features and a defined
cultural stratum (Stratum 6) at this site. Two of the five pollen samples
contained an insufficient concentration of pollen for interpretation. The
remaining three samples provide information concerning possible plant resources
processed at the site. Three artifacts from the site were analyzed for possible
protein residues. Inmmological studies have shown that protein residues from
a tooIs surface can be identified using modified forensic procedures. Protein
residue analysis is used to provide information concerning animal resources that
may have been utilized by the occupants of 5RB3691.

遗址5RB3691坐落于美国科罗拉多州西部的兰杰利（Rangely）与米克（Meeker）两镇之间，据信属于晚古风期（Late Archaic Period）。本次研究从该遗址的3处坑穴遗迹与明确的文化层（第6层）中采集并分析了5份花粉样品，其中2份样品的花粉浓度过低，无法用于相关解读。剩余3份样品则提供了该遗址可能加工过的植物资源相关信息。此外，研究人员还对该遗址出土的3件遗物开展了蛋白质残留物检测分析。免疫学研究表明，通过改良后的法医检测流程，可识别工具表面留存的蛋白质残留物。蛋白质残留物分析可用于获取该遗址先民可能使用过的动物资源相关信息。
