The aim of this study is to identify the preferred animal species at Byzantine city of Amorium and accordingly to find the spatial relationship between context and the purpose of animal use such as dietary habits, workshop activities, possible socioeconomic differentiation and subsistence economy as well as the ecology of Amorium environment. The animal bones were examined in order to determine their species. The identified animal bones were assessed by calculating the frequencies of the each species. Thus, which species were the most essential for the diet, and the basic aims of the animal economy, could be determined. In addition to domestic animals, the wild fauna was also studied to answer the question of which species were chosen for exploitation and whether or not wild sources were of considerable portion, gathered by fishing and hunting. For the spatial analysis, the species compositions as well as the skeletal representation tables of each assemblage of each different context were studied. The species composition appeared similar amongst most of the contexts but the skeletal representation tables gave more information on the use of species, especially allowing the separation of contexts containing domestic refuse and the contexts that had an overwhelming proportion of bones elements that could have been used for industrial activities (bone working).
