Diseño y evaluación de un protocolo de extracción múltiple de restos vegetales, silicofitolitos, polen, parásitos, isótopos estables y ADN de heces de Lama guanicoe
The most commonly-used extraction methods for biological proxies are based on dividing each coprolite to analyze each proxy separately. However, the interpretation of results has limitations.

| Sumario: | The most commonly-used extraction methods for biological proxies are based on dividing each coprolite to analyze each proxy separately. However, the interpretation of results has limitations. The aim of the present work is to design a new multiproxy protocol for feces of South American camelids. The protocol was based on reducing the use of chemical compounds in order to recover multiple proxies from a single sample. Theoretical and methodological considerations were taken into account to improve the protocol. The standard protocol was modified considering the requirements of multiproxy analysis. The experimental protocol was tested with a set of four guanaco (Lama guanicoe) feces from Patagonia, Argentina. After extraction, silica phytoliths, pollen types, and parasite remains were well-preserved and identified. Zoological origin was determined from DNA analysis. The results are discussed in light of various theoretical and methodological considerations. The implementation of this multiproxy extraction protocol in coprolites is an avenue for future research. |
