POLLEN, STARCH, PARASITE, MACROFLORAL, AND/OR PROTEIN RESIDUE ANALYSES AT FORT THORNBURGH, SITE 42DA1005, AND SITE 42DC1424, UTAH

Samples from three archaeological sites were examined for pollen, starch, and macrofloral remains. A single sample from a probable historic trench privy at Fort Thornburgh in northeast Utah was examined for pollen, starch, and parasites to detect evidence of foods consumed, as well as the possibility that parasite eggs were present. Two samples from 42Da1005, a dual component site with occupations dating from the Archaic and Fremont periods, were examined for pollen, starch and macrofloral remains to interpret environment and potential economic uses of the site. One metate wash and one cist fill sample from 42Dc1424, dated by the presence of an Elko Corner-notched projectile point, were examined for pollen, starch, and macrofloral remains to determine environment and possible uses of the site.

本次研究对三处考古遗址的样本开展了孢粉（pollen）、淀粉粒（starch）以及大植物遗存（macrofloral remains）的检测分析。其中，犹他州东北部索恩伯里堡（Fort Thornburgh）一处疑似历史时期壕沟式厕所的单一样本，额外增加了寄生虫（parasites）检测，以辨识先民食用食物的相关证据，同时排查是否存在寄生虫卵。遗址42Da1005为兼具阿恰德（Archaic）与弗里蒙特（Fremont）时期人类活动遗存的双组分遗址，本次对其中两件样本开展孢粉、淀粉粒与大植物遗存检测，以解析该遗址的古环境与潜在经济用途。遗址42Dc1424依据出土的埃尔科大凹刻投射尖状器（Elko Corner-notched projectile point）进行年代断代，对其中1件磨石盘（metate）冲洗遗存样本与1件石棺填土（cist fill）样本开展孢粉、淀粉粒与大植物遗存检测，以明确该遗址的古环境与可能的功能用途。
