During the last years, archaeozoological studies carried out on palaeolithic assemblages have shown a great improvement in several topics of special interest regarding the subsistence behaviour of ancient human societies, the development of economic systems and social and Taphonomical studies, experimental archaeology and ethological and ethnological information have provided a great amount of new interpretative procedures about past human societies which need to be updated.This session aims to propose integrated approaches allowing new insights about the livelihoods of Palaeolithic human groups whatever the geographical area and the chronology concerned.
