Late middle palaeolithic and early upper palaeolithic in poland in the light of new numerical dating

Although the first numerical dating of Middle and Upper Palaeolithic sites in Poland was applied at the beginning of the second half of the 20th century, it has only been in the last two decades that a data increase has been recorded, making it possible to discuss both the development of human behaviour and cultural phenomena in time perspective. This paper aims to show the chronological diversity of sites dating from the beginning of the Weichselian glaciation (MIS 5a – MIS 5d, GI-19 – GI-23, Greenland Interstadials) to the middle part of MIS 3 (GI-8 – GI-10). We considered sites dated mainly by thermoluminescence dating (OSL) and radiocarbon dating. We relied on a series of recent datings. We attempted to analyse the stratigraphic integrity, the archaeological finds and the numerical dating results. Through OSL dating, we could establish the chronology of Micoquian sites, previously regarded as middle Pleistocene, to the last glaciation. The dating compilation also shows that the Late Middle Palaeolithic and Early Upper Palaeolithic (EUP) sites are unlikely to overlap, or if they do, it is only over a small period. Unfortunately, this period is poorly interpreted because it spans the limit of the radiocarbon dating reliability and goes beyond the bounds of the calibration curve. Confronting the datings of the Lincombian-Ranisian-Jerzmanowician (LRJ) complex and the oldest finds associated with Aurigniacian sites in Poland lead to the conclusion that these sites may have co-occurred for some time.
