POLLEN, PHYTOLITH, STARCH, PARASITE, MACROFLORAL, AND ORGANIC RESIDUE (FTIR) ANALYSIS OF COPROLITIC MATERIAL FROM THE EAGLE POINT SHELTER (5RB4662), RIO BLANCO COUNTY, COLORADO

Two separate and distinctly different samples of coprolitic material from a midden pit at the Eagle Point Shelter (5RB4662) in Rio Blanco County, Colorado were submitted for pollen, phytolith, starch, parasite, macrofloral, and organic residue analysis, the latter using Fourier Transform Infrared Spectroscopy (FTIR). One coprolite fragment appears to be human, while a smaller fragment appears to be canid. The combination of multiple analyses is used to gain information regarding diet and local vegetation.

本研究送检了两份采自美国科罗拉多州里奥布兰科县鹰点庇护所（Eagle Point Shelter，编号5RB4662）贝丘坑的独立且特征迥异的粪化石质材料（coprolitic material）标本，将对其开展孢粉、植硅体、淀粉粒、寄生虫、大植物遗存以及有机残留物分析，其中有机残留物分析采用傅里叶变换红外光谱（Fourier Transform Infrared Spectroscopy，FTIR）法。其中一块粪化石碎片疑似源自人类，另一块尺寸更小的碎片则疑似来自犬科动物。通过多类分析方法的整合应用，可获取与饮食及当地植被相关的信息。
