- Châtelperronian cultural diversity at its western limits: shell beads and pigments from La Roche-à-Pierrot, Saint-Césaire.Publication . Bachellerie, François; Gravina, Brad; Rigaud, Solange; Dayet, Laure; Thomas, Marc; Lebreton, Loïc; Morin, Eugène; Lesage, Camille; Falguères, Christophe; Bard, Edouard; Bahain, Jean-Jacques; Baillet, Mickaël; Beauval, Cédric; Bordes, Jean-Guillaume; Culioli, Gérald; Devièse, Thibaut; Flas, Damien; Garbé, Lisa; Guérin, Guillaume; Lacrampe-Cuyaubère, François; Lahaye, Christelle; Mallol, Carolina; Marot, Josserand; Maureille, Bruno; Michel, Alexandre; Muth, Xavier; Regniers, Olivier; Tartar, Elise; Teyssandier, Nicolas; Thibeault, Adrien; Todisco, Dominique; Tombret, Olivier; Rougier, Hélène; Crevecoeur, IsabelleThe timing and mechanisms underlying the gradual replacement of Neanderthal populations by groups have elicited heated debate for decades. The Châtelperronian of France and northern Spain has figured prominently in these discussions. While the Neanderthal authorship of this techno-complex is far less certain than previously thought, the Châtelperronian is now generally accepted as being among the first genuine Upper Paleolithic industries in Eurasia rather than a "transitional" stone tool technology. Here, we report the first association of shell beads with Châtelperronian artifacts from new excavations at the site of La-Roche-à-Pierrot, Saint-Césaire (France), supported by a multiproxy spatial analysis that incorporates site formation processes. Similar types of personal ornaments are unknown from Middle Paleolithic contexts. Comparable examples have, however, been recovered from contexts penecontemporaneous with the Châtelperronian in south-eastern Europe and around the Mediterranean. This hitherto undocumented combination of an early Upper Paleolithic industry and shell beads provides insights into cultural variability in western Europe and raises the question as to whether the makers of the Châtelperronian were influenced by or formed part of the earliest dispersals of into the region.
- The Initial Upper Paleolithic from Tolbor-16, Mongolia: characteristics of the lithic assemblage and their evolutionary implicationsPublication . Zwyns, Nicolas; Tsedendorj, Bolorbat; Paine, Clea H.; Flas, Damien; Davaakhuu, Odsuren; Allshouse, Aurora F.; Gantumur, Angaragdulguun; Smith, Kevin N.; Byambaa, Gunchinsuren; Galfi, JovanAccording to fossil evidence, the Initial Upper Paleolithic (IUP) refers to archaeological assemblages associated with the early dispersal of Homo sapiens across Eurasia. These assemblages are often described as exhibiting a combination of Middle and Upper Paleolithic typo-technological features or, more broadly, as a technology in progression from the former to the latter. Genetic evidence indicates that as members of our species moved across Europe and Asia, they encountered Neanderthal, Denisovan, and possibly other local populations. At the Eurasian scale, the IUP shows considerable variation, but to what extent this corresponds to a relatively unified cultural package strictly associated with our species, or a suite of unrelated technologies reflecting the complex dynamics of a global population turnover, remains unclear. Like most archaeological assemblages, however, the IUP illustrates a combination of adaptive and normative behaviors, along with some stochastic variation. Here, we investigate what drives typo-technological variation within an IUP assemblage to identify traits relevant for larger scale inter-regional comparisons. Specifically, we describe a lithic assemblage dated to ca. 45 ka cal BP from the site of Tolbor-16 in northern Mongolia. We identify three defining aspects of the IUP at the site, namely variation in core shape and size, patterns of blade core reduction, and the presence of Middle Paleolithic typo-technological features. Our goal is to clarify the influence of dynamic reduction processes on assemblage composition and, within the variation observed, to identify typo-technological features that are relevant for inter-regional comparisons and scenarios of population dispersal.
