Abstract

Faecal biomarkers are used to trace and identify the source of faecal matter at various types of archaeological sites. Until now, the focus has been centred on humans and domesticated animals. However, in caves, it's wild animals that play a role in the deposition of organic matter. To assess the participation of animals and humans at such sites through molecular markers it is crucial to recognize their biomolecular signature. We developed a database of faecal profiles of 14 species of modern wildlife animals and assessed common ratios for recognizing the source of faecal matter. We proposed an improved framework and applied it to a set of test samples from cave sites. Our research shows that faecal biomarker analysis in caves is indeed feasible.

应用甾醇和胆汁酸作为生物标志物在考古遗址洞穴沉积物中识别人类与野生动物粪便痕迹
在各种类型的考古遗址中,粪便生物标志物被用于追踪和识别粪便物质的来源。到目前为止,研究的焦点一直集中在人类和家养动物身上。然而,在洞穴中,野生动物在有机物的沉积中起着重要作用。为了通过分子标记评估动物和人类在这些位点的参与,识别它们的生物分子特征是至关重要的。我们建立了14种现代野生动物的粪便资料数据库,并评估了识别粪便物质来源的常见比例。我们提出了一个改进的框架,并将其应用于一组来自洞穴遗址的测试样本。我们的研究表明,在洞穴中分析粪便生物标志物确实是可行的。

期刊介绍: Archaeometry is an international research journal covering the application of the physical and biological sciences to archaeology, anthropology and art history. Topics covered include dating methods, artifact studies, mathematical methods, remote sensing techniques, conservation science, environmental reconstruction, biological anthropology and archaeological theory. Papers are expected to have a clear archaeological, anthropological or art historical context, be of the highest scientific standards, and to present data of international relevance. The journal is published on behalf of the Research Laboratory for Archaeology and the History of Art, Oxford University, in association with Gesellschaft für Naturwissenschaftliche Archäologie, ARCHAEOMETRIE, the Society for Archaeological Sciences (SAS), and Associazione Italian di Archeometria.
