STARCH, PROTEIN RESIDUE, ORGANIC RESIDUE (FTIR), MACROFLORAL ANALYSIS, CHARCOAL IDENTIFICATION, AND AMS RADIOCARBON DATING OF SAMPLES FROM SITES 42JB1732, 42JB1739, 42JB1749, 42JB1760, 42JB1764, KEG MOUNTAIN RANCH, AND 42TO3974, UTAH

Lithic tools, groundstone, fire-cracked rock, charcoal, and sediment samples from sites 42JB1732, 42JB1739, 42JB1749, 42JB1760, 42JB1764, and Keg Mountain Ranch, in the Old River Bed Valley, western Utah, were submitted for starch, protein residue, organic residue, and macrofloral analyses, as well as charcoal identification and AMS radiocarbon dating. The samples were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). A basalt chopper from Clovis site 42TO3794, which is situated within the Dugway Proving Ground in the Cedar Mountains of Utah, was also submitted for protein residue analysis. Starch and macrofloral analyses provided information concerning plant resources utilized by the various occupants of these sites, while protein and organic residue analyses provided both plant and animal subsistence information. A total of seven radiocarbon dates were obtained on charcoal from five of the sites.

本数据集涵盖采自犹他州西部老河床谷的42JB1732、42JB1739、42JB1749、42JB1760、42JB1764以及凯格山牧场遗址的石质工具、磨制石器、火烧岩、木炭与沉积物样品。上述样品被送检以开展淀粉粒、蛋白质残留物、有机残留物和大植物遗存分析，同时进行木炭鉴定与加速器质谱（Accelerator Mass Spectrometry, AMS）放射性碳定年。本次研究采用傅里叶变换红外光谱法（Fourier Transform Infrared Spectroscopy, FTIR）对样品的有机残留物进行检测。另一件采自犹他州雪松山脉达格威试验场内克洛维斯（Clovis）遗址42TO3794的玄武岩砍砸器，也被送检开展蛋白质残留物分析。淀粉粒与大植物遗存分析可揭示上述遗址不同使用者所利用的植物资源，而蛋白质与有机残留物分析则可提供动植物生计相关的研究信息。研究团队从其中5处遗址的木炭样本中共获取7组放射性碳测年数据。
