Paleofeces

Paleofeces (UK: Palaeofaeces) are ancient human feces, often found as part of archaeological excavations or surveys. The term coprolite is often used interchangeably. Intact feces of ancient people may be found in caves in arid climates and in other locations with suitable preservation conditions. They are studied to determine the diet and health of the people who produced them through the analysis of seeds, small bones, and parasite eggs found inside. The feces can contain information about the person excreting the material as well as information about the material itself. They can also be chemically analyzed for more in-depth information on the individual who excreted them, using lipid analysis and ancient DNA analysis. The success rate of usable DNA extraction is relatively high in paleofeces, making it more reliable than skeletal DNA retrieval.
