In 2017 new archaeological fieldwork at two Early Neolithic sites in the district of Tübingen,  Ammerbuch-Entringen and Ammerbuch-Pfäffingen was initiated. These sites are situated on the southwestern periphery of the overall  distribution area of the oldest LBK. At the same time they lie in the overlap area with La Hoguette, one of the oldest ceramics-producing cultural groups in western Central Europe. The excavated sites provide new data on the first permanent settlements in the region and their influence on landscape genesis. Based on the available stratigraphic sequences, it is now for the first time possible to construct a radiocarbon-based high-resolution chronology for the development of the LBK in southwestern Germany. Accompanying paleoecological and anthropologic studies provide a better understanding of the influence of the first farmers and livestock herders on the natural environmental change. The results of our investigations show that dramatic changes in the landscape already occurred during the very first settlement, and which continue until today, and offer new insights into the chronological positioning of the advent of the Neolithic in Central Europe.
