While reviews of comparisons between multi-grain OSL ages and independent chronological information are available in the literature, there is hardly any such performance test for single-grain OSL ages. And yet, this is all the more needed as the interpretation of single-grain dose distributions remains a difficult task, given the typically considerable dispersion in equivalent dose values measured by OSL -and the numerous sources of such dispersion in measurements. In this study, we present the OSL study of 19 samples for which independent age control is available, and whose ages range from 2 to 46 ka. Based on multi-grain OSL age estimates, these samples are presumed to have been both well-bleached at burial, and unaffected by mixing after deposition. Two ways of estimating single-grain ages are then compared: the standard approach on the one hand, consisting of applying the Central Age Model to D e values determined with the Analyst software; on the other hand, the central dose model recently proposed by Combès et al. (Combès, B., Philippe, A., Lanos, P., Mercier, N., Tribolo, C., Guerin, G., Guibert, P., Lahaye, C., in press. Quaternary Geochronology). The median of the relative discrepancy between single-grain OSL and reference ages is about twice as large for the standard approach (12%) than with the Bayesian model (7%). Statistical tests show that, based on our (limited) data set, the difference between the two models seems to be significant for samples in the age range 4-46 ka. Finally, the influence of various factors on the (in-)accuracy of single grain OSL ages is discussed; it appears that the accuracy of ages estimated in a standard way decreases when age is increased, while the Bayesian model seems more robust. This study also shows that (i) there is no 20 % limit on the CAM overdispersion parameter for well-bleached samples; (ii) dose recovery experiments do not seem to be a very reliable tool to estimate the accuracy of a SAR measurement protocol for age determination. Highlights-Samples with independent age control are dated by OSL -Their ages range from 2 to 46 ka -Multi-grain OSL ages indicate no bleaching/mixing problem -Single-grain OSL is analysed using two different models -A Bayesian approach is expected to lead to improved accuracy

“…Châtelperronian lithic technology is arguably one of the most well-studied and well-described of any of Europe's Middle to Upper Palaeolithic industries (Bricker and Laville, 1977;Boëda, 1991;Guilbaud, 1993;Pelegrin, 1995;Harrold, 2000;Connet, 2002Connet, , 2019Bordes, 2003;Roussel and Soressi, 2006;Grigoletto et al, 2008;Bachellerie, 2011;Bordes and Teyssandier, 2011b;Roussel, 2011;Soressi, 2011;Aubry et al, 2012Aubry et al, , 2014Baillet et al, 2014;Roussel et al, 2016b;Bodu et al, 2017;Discamps et al, 2019;Rios-Garaizar et al, 2022).

“…The generally small thickness of blade platforms (~2-5mm), frequent soft abrasion of the external platform edge, ~90 exterior platform angles, common occurrence of splintered bulbs (esquillement de bulbe), weakly developed bulbs of percussion, and low frequency of pronounced internal platform 'lips' are consistent of a marginal application of force using a soft-stone hammer for plein debitage (e.g. Pelegrin, 1995;Bachellerie, 2011;Roussel et al, 2016;Bodu et al, 2017;Rios-Garaizar et al, 2022;Rios-Garaizar et al, 2012;Michel et al, 2019;Aubry et al, 2012;Aubry et al, 2014). Internal hard-hammer percussion is reported however, specifically for larger initialisation/maintenance products (Pelegrin, 2011) or the discrete production of blanks for end-scrapers (Michel et al, 2019).…”

The Middle to Upper Palaeolithic transition in France and northern Spain reflects the transition from Neandertals to Homo sapiens and the emergence of novel cultural entities and standardised laminar technologies between ~50 and 40 thousand years ago. The Chatelperronian stone tool industry sits at the centre of this period, and is commonly considered as representing a geographically isolated archaeological entity produced by late Neandertals. However, debate as to the makers and origin of this industry has long persisted. Fuel has recently been thrown onto this discussion through the formulation of a hypothesis in which the Chatelperronian directly originates from the Northern Early Ahmarian industry of the Levant. This model proposes that the Chatelperronian is in fact indicative of a direct migration of a population of Homo sapiens from the Levant to France around 44-40 thousand years ago, potentially via the crossing (or series of crossings) of the Mediterranean Sea. Such a scenario would have significant implications for how we interpret this key portion of recent human evolutionary history. In this paper, we highlight some of the prospects and pitfalls of an intrusive origin model for the emergence of the Chatelperronian industry in western Europe taking into account technological, chronological, geographic, and stratigraphic perspectives. To frame this discussion, we review the state of understanding on the Chatelperronian and provide a detailed, synthetic review of Chatelperronian lithic technology. Our review reinforces the distinctive and fully Upper Palaeolithic character of this industry, and we subsequently suggest a few avenues of research which, in our opinion, may help shed progressively clearer light on the demographic and cultural processes operating during the Middle to Upper Palaeolithic transition in western Europe.

“…Therefore, reconstructing past climate changes at local‐ and regional‐scale spatial dimensions is necessary to deepen our understanding of Paleolithic activity in specific areas. Past climate changes can be inferred at Paleolithic sites using various proxies, including physical (e.g., lithological features, magnetic susceptibility, and grain size; Aubry et al, 2014; Bae, Li et al, 2018; Gribchenko, 2006; Hong et al, 2018; Liu et al, 2010; Shin et al, 2005) and biological (e.g., organic matter content, C/N ratio, and carbon isotope values) indicators. Earlier studies in Korea also suggested that carbon isotope values may help reconstruct past climate changes at Paleolithic sites (Hyun et al, 2015; Jha et al, 2020; Krajcarz et al, 2014).…”

Possible linkage between Paleolithic site occurrence and past climate change in the central Korean Peninsula

Korea's Paleolithic sites are primarily located in riverine environments and the margins of alluvial fans. More than 100 Paleolithic excavations have been conducted in the Korean Peninsula, but the relationship between the locations of these sites and past climate change has received little attention. In this study, we investigated this relationship at a Paleolithic site in Wonju city, Korea, that contained two cultural layers and yielded a total of 336 stone artifacts. The lithological units present at the site indicate that the sedimentary environment changed from a riverine sandy channel to an alluvial plain owing to channel migration at the Marine Isotope Stage (MIS) 4. The alluvial plain sediments deposited during MIS 4-2 are characterized by low sand content (<5%) and two soil wedges. Most Paleolithic artifacts were excavated from the upper soil wedge, deposited during MIS 3 under relatively warm and wet conditions associated with global climatic changes (as indicated by sea level or continental ice volume) and the East Asian summer monsoon. The number of Paleolithic cultural layers increases in late MIS 3 in other regions, suggesting that climate conditions are an essential factor in the development of Paleolithic cultural layers.
