Reference collections of phytoliths from plant taxa commonly used by the ancient inhabitants of an archaeological site are critical to researchers conducting analyses on these microbotanical remains. Phytoliths recovered from the site are compared to those in reference collections to make inferences about which taxa were being used, as well as where, why and how. This study presents one of the first reference collections of phytoliths from selected taxa likely to have been used by Native American peoples living in the Great Basin area. The results are presented as a list of taxa which we sampled, and that are known to have been used by these tribes, such as the Shoshone and Ute, with illustrations of the range of phytolith morphotypes produced by each taxon. Our hope is that this tool will prove to be a ready and valuable resource for any researchers conducting phytolith analysis at Great Basin Native American sites.

对大盆地美洲原住民通常使用的精选本地植物分类群产生的植物石的研究

考古遗址的古代居民通常使用的植物分类单元中的硅藻石参考收藏品，对于研究人员对这些微型植物残骸进行分析至关重要。将从现场回收的植硅石与参考馆藏中的植硅石进行比较，以推断出正在使用哪种分类单元，以及在何处，为什么以及如何使用。这项研究提出了来自某些分类群的硅藻石的第一个参考集合之一，这些参考集可能被居住在大盆地地区的美洲原住民所使用。结果显示为我们抽样的分类单元列表，已知这些部落已使用它们，例如肖肖尼人和尤特人，并举例说明了每个分类单元产生的叶板形态类型。
