Within the East European Plain, the Podolian Upland have been heavily settled by palaeolithic human populations. We focus here about the extra-Carpathian area, particularly the Prut-Dniester basin during Upper Pleniglacial, to better understand Upper Palaeolithic cultures. Moreover there are few sites related to the Last Glacial Maximum. That is why the faunal material from Valea Morilor could provide further information. We study the use of natural resources, in particular of animal origin, to inform the strategies of occupation of the territories, placed in their palaeoecological framework. We use zooarchaeological methods to determine the faunal spectrum, mortality pro files of animals, their anatomical representation in relation with taphonomic processes and palaeoethnography to restore the involvement of human activities.
