“…The oldest of the lower limits of these authors' 95.4 % confi dence intervals for Isturitz's modeled cal BP results is 41,840, and the corresponding youngest upper limit is 40,078; both are fully consistent with the 39.9-41.5 ka cal BP range modeled for the entire technocomplex. The same applies to Les Cottés, dates for which have since been published (Talamo et al 2012 ). At this site, not only does the Protoaurignacian overlie the Châtelperronian, it is also separated from it by a 12 cm-thick sterile layer.…”

Supporting Assimilation views of Neandertal/modern human interaction, chronostratigraphic reasoning indicates that the "transitional" industries of Europe predate modern human immigration, in agreement with their association with Neandertals in the Châtelperronian at the Grotte du Renne and St.-Césaire. Supporting the Neandertals' species separateness and less developed cognition, those industries are alternatively claimed to relate to pioneer groups of modern humans; the latter would have been the true makers of the precocious instances of symbolic material culture that, under Assimilation, are assigned to the Neandertals. However, the taxonomy of the Kent's Cavern and Grotta del Cavallo dental remains is uncertain, and their poor stratigraphic context precludes dating by association. The opposite happens at the Grotte du Renne, whose stratigraphic integrity is corroborated by both taphonomy and dating. Not questioning that the Early Ahmarian is a cultural proxy for modern humans and a source for the Protoaurignacian of Europe, its claimed emergence ~46-49 ka ago at Kebara refl ects the dating of Middle Paleolithic charcoal-to be expected, because the Early Ahmarian units at the back of the cave are made up of reworked Middle Paleolithic sediments derived from the entrance. The dating of inherited material also explains the old results for the Aurignacian of Willendorf II and Geissenklösterle. At the latter, the dates on anthropically modifi ed samples of the hunted taxa (reindeer and horse) place its Aurignacian occupations in the same time range as elsewhere in Europe, after ~40 ka ago. The hypothesis that Neandertal/modern human contact in Europe resulted in a process of assimilation in connection with the spread of the Protoaurignacian ~41.5 ka ago remains unfalsifi ed.

“…Further evidence for the EA is also found in US02 and is referred to, at this site, as the Upper EA (UEA). The remaining and inter-stratified units (US 01, 03, 05 and 07) are virtually archaeologically sterile (see Table 2 in Talamo et al, 2012). These archaeologically sterile units clearly separate the major archaeological industries.…”

“…For example, only 0.5% modern contamination of a sample that dates to 40 ka BP, will result in an underestimation of 4.4 ka and, thus, a measured age of 35.6 ka BP (Higham, 2011), or 1% modern contamination of a sample >60 ka old, will result in a measured age of~37 ka BP . A swath of recent 14 C dating studies have confirmed how earlier 14 C ages produced on charcoal and bone from sites associated with the MP/UP transition have, in many cases, been underestimations because of small-scale post-depositional contamination by younger carbon that was not removed adequately during the laboratory pretreatment of the samples (e.g., Mellars, 2006;Higham et al, 2010Higham et al, , 2011Higham et al, , 2012Talamo et al, 2012;Wood et al, 2013). Application of newgeneration pretreatment techniques, such as acid-base wet oxidation and stepped-combustion (ABOX-SC) procedures for charcoal (Bird et al, 1999), molecular ultrafiltration procedures for bone collagen and X-ray diffraction and density separation procedures for shell (Douka et al, 2010), have been pushing back the ages for this critical period within the European Palaeolithic.…”

a b s t r a c tThe timing of the Middle Palaeolithic to Upper Palaeolithic transition in France is important to help understand when, where and how Neanderthals have been replaced by Homo sapiens. Radiocarbon dating has been the dating workhorse in constructing the chronological framework pertinent to these questions. In this study, we are testing whether single grain OSL dating has the accuracy and precision to be useful as a complementary dating method. The site of Les Cott es provides an ideal testing ground because of its stratigraphic integrity and reliable radiocarbon chronology. We applied single grain OSL dating of quartz to 19 samples and multi-aliquot MET-pIRIR dating of potassium-rich feldspar grains to 5 samples to explicitly test assumptions of pre-depositional resetting of the OSL signal and postdepositional exposure to variable beta dose rates. The good agreement between the single grain OSL and the multi-aliquot MET pIRIR ages suggest that the optical signals of both quartz and feldspar grains were reset prior to deposition and that much of the extra scatter observed in the equivalent dose distribution of quartz grains are likely due to the small-scale differences in beta dose delivered to individual grains. Both the quartz OSL and feldspar MET-pIRIR ages show great consistency with the 14 C ages on bone collected from the same units. This gives confidence in the measurement and analytical approaches used to derive both the equivalent dose and dose rate, the numerator and denominator, respectively, of the luminescence age equation. These results suggest that a systematic and detailed single grain OSL dating study can have the accuracy and precision that is necessary to play a powerful role in the dating of the Middle and Upper Palaeolithic transition and other questions of importance in this time range and geographical area.

Thus, although the different approaches produce equally accurate ages for this particular sample, there are mathematical grounds to support the validity of the intensity-subtraction procedure for robust age estimation more generally.…”
