POLLEN, STARCH, PARASITE, PHYTOLITH, MACROFLORAL, AND ORGANIC RESIDUE (FTIR) ANALYSIS OF COPROLITES FROM ROOM 225, WEST RUIN, AZTEC RUINS NATIONAL MONUMENT, AZTEC, NEW MEXICO

Aztec Ruins National Monument is the largest ancestral Puebloan community in the
Animas River Valley. Several multi-story buildings, smaller structures, and kivas represent
residential and ceremonial structures. Room 225 in West Ruin, a great house, contained
numerous coprolites, six of which were sent to PaleoResearch Institute. Of these six coprolites,
in order to remain within budgetary limits, three were selected for analysis that included finding
and identifying macrofloral remains, pollen, starch, phytoliths, parasite eggs, and organic
residue.

阿兹特克废墟国家纪念地（Aztec Ruins National Monument）是阿尼马斯河谷（Animas River Valley）内规模最大的普韦布洛祖先群落遗址。该遗址现存多处多层建筑、小型构筑物及基瓦（kivas），均作为居住与仪式建筑使用。西废墟的225号房间隶属于一座大屋（great house），其内出土了大量粪化石（coprolite），其中6件被送往古生物研究所（PaleoResearch Institute）。受预算约束，研究人员从这6件粪化石中选取3件开展分析，分析内容涵盖大植物遗存、花粉、淀粉粒、植硅体、寄生虫卵及有机残留物的检出与鉴定。
