Abstract
ABSTRACT Livestock fecal remains provide an important source of information on past animal husbandry systems and dung use. A combined micromorphological and biomolecular investigation of dung deposits brings new perspectives into past landscape land use and animal husbandry strategies by providing seasonal-scale information on livestock dietary intake as well as intensity of dung deposition in penning spaces. We conducted microstratigraphic analyses and compound-specific carbon stable isotope analysis of plant n-alkanes of dung deposits associated with pastoral nomadic winter campsites in Mongolia, in order to explore the floral origin of graze ingested by livestock and evaluate its potential biomolecular signatures. Preliminary results show that δ13C values of plant n-alkanes were unusually depleted when compared to carbon isotope values of plant n-alkanes in soil control samples recovered from landscapes with minimal anthropic activity. We highlight the importance of multi-proxy ethnoarcheological studies in identifying biomarkers that convey information on pastoralist animal exploitation practices.
期刊介绍:
Ethnoarchaeology, a cross-cultural peer-reviewed journal, focuses on the present position, impact of, and future prospects of ethnoarchaeological and experimental studies approaches to anthropological research. The primary goal of this journal is to provide practitioners with an intellectual platform to showcase and appraise current research and theoretical and methodological directions for the 21st century. Although there has been an exponential increase in ethnoarchaeological and experimental research in the past thirty years, there is little that unifies or defines our subdiscipline. Ethnoarchaeology addresses this need, exploring what distinguishes ethnoarchaeological and experimental approaches, what methods connect practitioners, and what unique suite of research attributes we contribute to the better understanding of the human condition. In addition to research articles, the journal publishes book and other media reviews, periodic theme issues, and position statements by noted scholars.
