This study aims to present the first results of fieldwork conducted by the teams of the Römisch-Germanische Kommission (Frankfurt am Main) and the Institute of Archaeological Sciences of Eötvös Loránd University (Budapest) in the scope of a joint project. The investigated tell site, Berettyóújfalu-Szilhalom is well known by prehistoric archaeology due to earlier excavations. The main goals of the project were to gain a better understanding of Late Neolithic tell formation processes, to investigate the relations of a tell and its adjacent horizontal settlement and to get a more detailed picture on the Late Neolithic–Early Copper Age transition. Therefore we re-opened the refilled trench of the excavation carried out in 1976, collected bone, soil and micromorphological samples for further examinations, performed geomagnetic prospections, made drillings and field surveys.
