Presented are the results of research into the fluvio-aeolian sedimentary succession at the site of Postolin in the Żmigród Basin, southwest Poland. Based on lithofacies analysis, textural analysis, Thermoluminescence and Infrared-Optical Stimulated Luminescence dating and GIS analysis, three lithofacies units were recognised and their stratigraphic succession identified: 1) the lower unit was deposited during the Pleni-Weichselian within a sand-bed braided river functioning under permafrost conditions within the central part of the alluvial fan; 2) the middle unit is the result of aeolian deposition and fluvial redeposition on the surface of the fan during long-term permafrost and progressive decrease of humidity of the climate at the turn of the Pleni to the Late Weichselian; 3) the upper unit accumulated following the development of longitudinal dunes at the turn of the Late Weichselian to the Holocene; the development of dunes was interrupted twice by the form being stabilised by vegetation and soil development.

Aunique set of mammoth bones and tusk was found in active gravel pit in vicinities of Zastruże near Żarów, Lower Silesia. The use of archaeological methods made it possible to uncover 17 bones belonging to a single individual (Mammuthus primigenius). This is the first record of so complete set of mammoth bones in the Lower Silesian region. Mammoth remains were found to be accompanied by some bones of a horse and a flint artifact. The mammoth bones were dated radiocarbon method at 23 790 š 160 years, that is at the beginning of the last Pleniglacial of the Weichselian Glaciation. The mammoth remains were embedded in slope sediments of a small valley so they did not occurin anatomical order.
