POLLEN, MACROFLORAL, AMS RADICOARBON DATING, AND PROTEIN RESIDUE ANALYSES AT SITE 24RL0371 FOR THE BAKKEN PIPELINE PROJECT, EASTERN MONTANA

Fill from a hearth at site 24RL0371 in eastern Montana, near the North Dakota border, was examined for pollen and macrofloral remains. Charcoal and charred botanics recovered from the hearth fill were submitted for identification and AMS radiocarbon dating. A projectile point also was examined for possible protein residues. This site is a pre-contact (Middle Archaic) lithic scatter and historic trash dump. The prehistoric component might have been used as a long-term or multi-seasonal campsite. Pollen, macrofloral, and protein residue analyses were used to help answer questions pertaining to resource utilization and site function. AMS radiocarbon dating provided temporal information.

对美国蒙大拿州东部、毗邻北达科他州边境的24RL0371遗址内一处火塘的填积物，开展了花粉与大植物遗存检测分析。从该火塘填积物中提取的炭屑与炭化植物标本，被送往相关机构进行物种鉴定与加速器质谱碳十四测年（AMS radiocarbon dating）。同时还对一件投射尖状器开展了潜在蛋白质残留物检测分析。该遗址属于前接触时期（中古风期，Middle Archaic）的石器散布点与近代垃圾堆积场。其史前遗存部分可能曾作为长期或多季营地使用。花粉、大植物遗存与蛋白质残留物分析，旨在解答与资源利用及遗址功能相关的学术问题。加速器质谱碳十四测年则提供了该遗址的年代学数据。
