Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

Archaeometry, EarlyView.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the
