Identifying sheep (Ovis aries) fetal remains in archaeological contexts

摘要: Abstract Studies on the identification of fetal sheep remains in archaeological sites are scarce comparison to abundant literature addressing methods for postnatal age determination. However, perinatal studies can provide important information about flock management Neolithic period. Motivated by extensive and neonatal assemblages recovered Bronze Age levels El Mirador cave (Sierra de Atapuerca, Spain), we have identified distinguished using morphological criteria complemented osteometric criteria. Skeletal development during period is less affected agents that influence skeletal (genetic, environmental, etc.). A priori , this makes determination actualistic data more reliable than remains. Starting from these premises, were analyzed osteological collection individuals Rasa Aragonesa breed IPE (Instituto Pirenaico Ecologia, Jaca, Spain). Veterinary based bone center ontogenesis metric also employed. The distinction qualitative anatomical consistent with results obtained data, specifically diaphyseal length measurement. In addition, large number specimen made it possible distinguish different phases accordance developmental phenomena.
