The Visibility of Mobility: Coprolites, Dung and Neolithic Herders in Central Saharan Rock Shelters

The archaeological landscape of the Tadrart Acacus massif (SW Libya, central Sahara) is made of sites testimony of complex systems of cultural-specific settlement and economic strategies stretching over millennia of occupation. Here, caves and rock shelters represent the main physiographic features exploited by prehistoric herders. Climate fluctuations, settlement patterns and economic strategies regulate the depositional and post-depositional processes documented in the excavated sites. In this regard, the site of Takarkori, thanks to its well-preserved archaeological record, which was extensively excavated, represents a highly valuable archive of past societal activities. We show how a multifaceted analysis of deposits and sediments of anthropogenic and biogenic origin, like dung and coprolites accumulations, may broaden the reconstruction of the cultural dynamics and variability of the Saharan Late Pastoral Neolithic (5700-4650 cal BP). Analysis of spatial distribution coupled with micromorphological investigation increased the reconstruction of the shelter's organisation and use, including its deposit’ formation processes. Pollen analysis highlighted aspects of seasonality among Late Pastoral herders attending the site, also contributing to deepen our knowledge on palaeoenvironment of Middle Holocene Sahara
