POLLEN, MACROFLORAL, AND PROTEIN RESIDUE ANALYSIS AT SITES 42WS2871 , 42WS2872, 42GA3818, 42IN1371, AND 24EM2686, SOUTHERN UTAH

Samples from five archaeological sites in southwest Utah were submitted for pollen and macrofloral analysis to provide information concerning plant resources utilized at the various sites. Artifacts from three of the sites were analyzed for possible protein residues to determine use of animal resources. Sites 42Ws2871 and 42Ws2872 are located within the city limits of St. George. Site 42Ws2871 is a rock shelter with numerous associated features. A conventional radiocarbon age of 310 ± 40 BP, which yields a calibrated age of 440-350 BP, was returned for a feature in this rockshelter. Pollen and macrofloral samples were collected from an ash concentration, two hearths, and an unlined pit feature located outside the shelter, as well as from three strata. Two hearths were sampled for pollen and macrofloral remains from 42Ws2872, an open air site that is considered to be prehistoric, but yielded no diagnostic artifacts.
Sites 42Ga3818 and 421n1371 are located along State Route 20, twenty miles north of Panguitch. Site 42Ga3818, which represents a Fremont occupation, yielded a measured age of 1340 ± 40 BP, which translates to a calibrated age of 1300 BP. Pollen and macrofloral samples were collected from a hearth and an unlined pit at 42Ga3818. A projectile point also was submitted for protein residue analysis. 42In1371 is a lithic scatter with no features. No radiocarbon age is available from this site, although occupation appears to be Archaic to Fremont. Three artifacts were tested for possible protein residues, while soil containing cultural material was sampled for pollen and macrofloral remains.
42Em2686 is a rockshelter located at the western edge of the San Rafael Swell near the town of Moore. This Fremont site yielded a measured radiocarbon age of 1120 ± 40 BP, which is calibrated to 1160-1060 BP. Hearths located near the shelter dripline were sampled for pollen and macrofloral remains, while a projectile point from outside the rockshelter and a shark tooth from within the shelter were analyzed for possible protein residues (Jody Patterson, personal communication, 24 March, 2003).

犹他州西南部5处考古遗址的样本被送检，开展花粉与大植物遗存（macrofloral）分析，以获取各遗址所利用的植物资源相关信息。其中3处遗址的出土遗物被检测是否存在蛋白质残留物（protein residues），以此判断其动物资源利用情况。
42Ws2871与42Ws2872遗址位于圣乔治（St. George）市域范围内。42Ws2871为一处岩棚（rock shelter），伴生大量遗迹。该岩棚内一处遗迹的常规放射性碳年代（radiocarbon age）测定结果为310±40 BP，校正年代（calibrated age）为440~350 BP。研究人员从该岩棚外的一处灰烬堆积、两处火塘（hearth）、一处无衬里坑状遗迹以及3个地层中采集了花粉与大植物遗存样本。42Ws2872为一处露天遗址，被判定为史前时期遗址，但未出土可断代的典型遗物，研究人员从该遗址的两处火塘中采集了花粉与大植物遗存样本。
42Ga3818与42In1371遗址位于潘圭奇（Panguitch）以北20英里的20号州道沿线。42Ga3818为弗里蒙特（Fremont）文化遗存遗址，实测放射性碳年代为1340±40 BP，校正后年代为1300 BP。研究人员从该遗址的一处火塘与一处无衬里坑中采集了花粉与大植物遗存样本，另有一件投射尖状器（projectile point）被送检以开展蛋白质残留物分析。42In1371为一处无遗迹的石器散布点（lithic scatter），该遗址未获取放射性碳年代数据，但据推测其年代处于古印第安（Archaic）至弗里蒙特时期。研究人员对3件遗物进行了蛋白质残留物检测，并采集了含文化遗物的土壤样本以获取花粉与大植物遗存。
42Em2686为一处岩棚，位于圣拉斐尔穹地（San Rafael Swell）西缘，毗邻穆尔（Moore）镇。该弗里蒙特文化遗址的实测放射性碳年代为1120±40 BP，校正后年代为1160~1060 BP。研究人员从该岩棚滴水线附近的火塘中采集了花粉与大植物遗存样本，并对岩棚外的一件投射尖状器与岩棚内的一枚鲨鱼齿开展了蛋白质残留物检测（乔迪·帕特森个人交流，2003年3月24日）。
