A selection of 37 burnt flints from Jelinek's excavations at Tabun were dated by thermoluminescence. The results indicate that the bottom of unit I (Garrod's Layer C) should be given an age of 171±17 kybp(transition from oxygen isotope stage 7 to 6) and that units XIII to II (Layers Ed to D) were deposited betweenc. 330 and 210 kybp,i.e.during...

The stratigraphic and lithic evidence at the site of Bérigoule is not sufficient for the determination of the age of two Mousterian archaeological layers. Thermoluminescence (TL) dating of heated flint from the two levels provides chronometric age estimates. The TL-ages show a high degree of variability, ranging from 54 to 90 ka for Level I and...

What are the long-term consequences of invasive species? After invasion, how long do ecosystems require to reach a new equilibrium? Answering these questions requires long-term, high-resolution data that are vanishingly rare. We combined the analysis of environmental DNA extracted from a lake sediment core, coprophilous fungi, and...

Le site de Payre est un gisement de la moyenne vallée du Rhône, daté de la fin du Pléistocène moyen et début du Pléistocène supérieur (fin du MIS 8 au début du 5) selon les analyses radiométriques et paléoenvironnementales. Lors de fouilles qui se sont déroulées de 1990 à 2002, ce gisement a livré une séquence de plusieurs niveaux...

The thermoluminescence dating method was applied to 77 heated flints from the Mousterian layers of Hayonim Cave in order to provide a precise TL-based chronology for this important Levantine sequence. A detailed dosimetric study was performed by using 76 dosimeter capsules and revealed strong spatial dose-rate variations. In parallel, Fourier...
