GDRE Workshop in Brussels: 1-2 July 2010 Elena Marinova, Veerle Linseele, RBINS, Brussels; Marlu Kühn IPNA, Basel Title: Bioarchaeological research on animal dung: possibilities and limitations Aims of the Workshop: Animal dung is a potential source of information on various paleoeonomical and paleoecological topics, which in many cases can not be obtained through other bioarchaeological studies. Until now no common methodological approaches exist among people working on animal dung. In the light of this, the proposed workshop has the aim to establish what methods have or can be used for the analysis of archaeological dung and what kind of questions, related to the research themes of the BIOARCH network, they can answer. Three main topics are to be discussed: methodology of archaeobiological studies on dung taphonomical aspects interpretative value, concentrating mainly on animal husbandry related questions Since the writers of this proposal are archaeobotanist or archaeozoologist, emphasis is now on these angles of research. However, input from different types of specialists (ancient DNA analysis, paleoparasitologists, biochemical analyses) is very much encouraged. Methodology - Species identification of archaeological dung remains (based on shape and size, plant remains, DNA, chemical analyses, insect remains, indirect evidence, etc.). - Variety of plant remains recovered from dung (pollen, phytoliths, seeds/fruits, vegetative plant remains, epidermis, etc.) and methods applied for their analysis. - Interpretation of results in relation to the applied methods (e.g. interpretation of pollen data versus interpretation of data from the analysis of plant macrofossils). - Representation of plant remains in the dung, e.g. differences in preservation of plant parts from evergreen/deciduous trees, herbs, grass. - Questions for further research projects, e.g. feeding experiments. Taphonomy: - Types of dung (waterlogged, dry, mineralised, charred) and their different scientific potential. - Contribution of dung to the formation of archaeological layers, and the plant assemblages found in these layers. - Dung for fuel, tempering of mud bricks. Interpretation - Early presence of domestic animals. Some early sites yielded dung but no bones. - How to detect the difference between feeding and browsing. - How to detect feeding of hay (grass, herbs, leaves). - Mobility and seasonality. - Hygienical conditions in the settlements. - Stabling/housing or not. - How to detect fire management of woods and/or woodland edges. - Reconstruction of the environment. - Impact of animal husbandry on the environment.
