Abstract

This paper presents the results of phytolith analysis carried out on sediments from Theopetra Cave in Thessaly, Central Greece. Theopetra is one of the most important late Pleistocene sites in the region, with occupation spanning the Middle Palaeolithic to the end of the Neolithic. The aim of this study is to contribute to our understanding of the nature of human occupation in the cave during the Palaeolithic and Mesolithic. Palaeoenvironmental issues are also addressed in order to understand the climate and vegetation around the cave during that time. Twelve layers of anthropogenic and geogenic origin which mark distinct occupation episodes have been sampled. The anthropogenic layers consist of combustion features and are valuable indicators of human activity within the cave, providing information on the types of vegetation collected for everyday activities and consumption. The geogenic sediments are mostly of natural origin and mark intervals during which the site was mostly unoccupied. They provide evidence for the climate and plant communities growing around the cave. The results point to intensive occupation of the cave during the transition from the penultimate glacial to the last interglacial, a period of mild climate, high precipitation and rich vegetation in the catchment area. Sporadic use of the cave is implied during the last glacial, followed by more frequent visits towards the end of the Pleistocene. A range of plants were used for fuel, food and other day-to-day activities. Theopetra is discussed in comparison with Klissoura, a key Palaeolithic cave site in southern Greece. A number of conclusions are drawn concerning life at the two sites and their surroundings, based on similarities and differences in phytoliths and other key environmental and dietary indicators.
