Current projects

Success, limits and failure of subsistence strategies in eastern Central Europe during the Early Gravettian and the Last Glacial Maximum.

DFG project, 2020-2023 (co-applicants from Austrian Academy of Sciences/Austrian Archaeological Institute, University of Cologne, and Institute of Prehistory and Early History FAU)

The Last Glacial Maximum (LGM, ca. 24,000-19,000 cal BP) was, contrary to popular belief, a period of relative climatic stability and resurgent human populations. Rather, the most inhospitable climatic conditions of the entire Upper Paleolithic occurred during the preceding Late Gravettian (ca. 29,000-25,000 cal BP). The focus of the project is on a cluster of sites in Austria, Moravia, and southern Poland, which – although sparsely populated – was unlike other regions north of 50°N not affected by population collapse during this climatic inhospitable phase. This raises the following questions: what made the region special and what adaptive strategies did its inhabitants develop? To answer these questions, we compare the environmental conditions and archaeological evidence of the LGM with those of the Early Gravettian, a period of cultural flourishing and comparatively favorable climatic conditions. We combine archaeological analyses (e.g., of lithic and organic tools), osteoarchaeological information, and data on sedimentology and the paleoenvironment (geochemistry, stable isotopes, mollusks, and others).
