Geoarchaeological patterns in the pre-desert and desert ecozones of northern Cyrenaica.

Geoarchaeological surveys were conducted in northern Cyrenaica in 2009 as part of the TRANS-NAP project. A major objective of the project is to understand tile relationship between regional environmental changes and human occupation patterns in northern Cyrenaica over approximately the past 200,000 years. This paper focuses on the results of surveys of the pre-desert and desert ecological zones in the south of the project's study region. The type, density and distribution of Palaeolithic sites were a particular focus of field research in the area. We report data from 42 archaeological sites in the pre-desert and desert zones, concentrating in particular on sites associated with palaeolakes and fan deposits. Analysis of the data reveals several patterns whereby particular archaeological signatures are associated with particular landforms. There is also a broader pattern across the region where sites assigned to the Middle Stone Age (MSA) period ate considerably more common than those characteristic of the Late Stone Age (LSA). It is argued that this geographic area is particularly sensitive to changes in global climate and that past occupation patterns during the Palaeolithic were strongly driven by changes in the region's hydrological regime.
