PROTEIN RESIDUE ANALYSIS OF THREE PROJECTILE POINTS FROM SITE LA 150615, RIO ARRIBA COUNTY, NEW MEXICO

Three projectile points and a single soil control sample were submitted for protein residue analysis from site LA 150615, located in Rio Arriba County, northern New Mexico. All three artifacts are from a pit house feature with a Pueblo I-II affiliation (ca. A.D. 700-1050). Protein residue analysis may help determine what animals were hunted, and/or what animal remains were processed using these tools.从位于新墨西哥州北部里奥阿里巴县（Rio Arriba County）的LA 150615遗址采集的3件投射尖状器（projectile point）与1份土壤对照样本，被送检以开展蛋白质残留物分析。该3件遗物均出自带有普韦布洛I-II期（约公元700-1050年）属性的半地穴式房屋遗迹。蛋白质残留物分析可助力明确上述工具曾用于狩猎何种动物，抑或曾加工过哪些动物遗体。
