The fluvio-lacustrine sequences in the Nihewan Basin, northern China, provide important terrestrial archives about Palaeolithic settlements and, therefore, about early human occupation in high northern latitude in East Asia. Here we present detailed ESR dating of the Donggutuo Palaeo-lithic site, located in this basin. Four levels A, B, C and E of the Donggutuo archaeological layer yield ESR ages ranging from 1060±129 ka to 1171±132 ka with a mean of 1119±132 ka. The ages are con-sistent with the paleomagnetic data, which show that the Donggutuo Palaeolithic site lies just below the onset of the Jaramillo normal subchron (0.99-1.07 Ma). Furthermore, our results indicate that the reliable ESR dating range of bleached quartz using Ti-Li centre can be effectively extended to 1100 ka and the Ti-Li centre was zeroed before the last deposition, which requires improvement of the understanding of the bleaching mechanism conditions.

Lithic assemblages from two main occupational phases of the Kraków-Spadzista B+B 1 are discussed in this paper, including assemblages from the Gravettian layer 6 and the Epigravettian layer 5. Assemblages from layer 6 represent a number of consecutive occupational episodes, subsequently reworked by solifluction. Consequently, the two main activities: butchering and production of lithic tools are mixed up in the cantent of layer 6. Limited number of refits from this layer confirms the horizontal and vertical displacement of the whole lithic and bone material, making impossible the reconstruction of particular occupational and functional episodes. During the formation of layer 5, the site was not functionally related to mammoth hunting and butchering, but focused on exploitation and processing of local flint. Numerous technological refits indicate that the on-site lithic production included not only blades, but also pre-cores and cores.

Traseological analysis has been performed on 225 burin points (in technological sense) on 181 artefacts from the Upper Palaeolithic site Kraków-Spadzista, sectors B+B 1, in three chronological horizons: Aurignacian (layer 7), Gravettian (layer 6), and Epigravettian (layer 5). The percentage of functionally undefined tools is up to 30% in all horizons. Most frequently, burin blows shaped the edge of tools used as scrapers, relatively often they shaped the edge of tools functioning as burins; the function of perforators and knives were less important. Only the Gravettian horizon is characterised by a larger number of tools functioning as knives; this indicates clearly that the main activity during the Gravettian occupation was butchering. Some specimens used as a projectile points are characterised by impact fractures.

The sequence of three molluscan assemblages characterizing changes of the climate was found in the section of the middle and upper Vistulian loess. The first assemblage includes a relatively rich fauna with Arianta arbustorum, corresponding with the interpleniglacial or interstadial. Assemblages with Succinea oblonga and Pupilla loessica occur in the upper part of loess covering deposits of the bone-bed type. They point to the cold-humid and cold-dry phases of the Vistulian pleniglacial, respectively.
