Osteometry of Duck Species in Northwestern Europe—A Reassessment of Woelfle's (1967) Dataset
International Journal of Osteoarchaeology, EarlyView.ABSTRACT This study revisits and expands upon Elisabeth Woelfle's (1967) foundational analysis of bone morphology and osteometry, which has long been a key reference for zooarcheological identification of duck species in northwestern Europe. By examining Woelfle's unpublished measuring protocols and incorporating 523 newly measured specimens, we ...
