Neandertals made the first specialized bone tools in Europe.

Modern humans replaced Neandertals ∼40,000 y ago. Close to the time of replacement, Neandertals show behaviors similar to those of the modern humans arriving into Europe, including the use of specialized bone tools, body ornaments, and small blades. It is highly debated whether these modern behaviors developed before or as a result of contact with modern humans. Here we report the identification of a type of specialized bone tool, lissoir, previously only associated with modern humans. The microwear preserved on one of these lissoir is consistent with the use of lissoir in modern times to obtain supple, lustrous, and more impermeable hides. These tools are from a Neandertal context proceeding the replacement period and are the oldest specialized bone tools in Europe. As such, they are either a demonstration of independent invention by Neandertals or an indication that modern humans started influencing European Neandertals much earlier than previously believed. Because these finds clearly predate the oldest known age for the use of similar objects in Europe by anatomically modern humans, they could also be evidence for cultural diffusion from Neandertals to modern humans.

A revised chronology for the Grotte Vaufrey (Dordogne, France) based on TT-OSL dating of sedimentary quartz.

Grotte Vaufrey, located in the Dordogne region of southwestern France, is well known for its substantial archaeological sequence containing a succession of Acheulean and Mousterian occupations. While over the last thirty years numerous studies have attempted to outline a detailed chronostratigraphy for this important sequence, the failure to employ a common chronological framework has complicated its interpretation. Here, we aim to resolve these inconsistencies by providing a new chronology for the site based on luminescence dating. To this end, thermally-transferred optically stimulated luminescence (TT-OSL) dates were obtained from eight sediment samples distributed throughout the sequence, which, when combined with already available chronological information, produce a new chronostratigraphic model for the site. Our results demonstrate that the Typical Mousterian extends from MIS 7 to MIS 5, while the earliest Acheulean occupation could be associated with MIS 8 and may date to as early as MIS 10. When compared with other regional sequences, the Acheulean levels from the Grotte Vaufrey provide evidence for one of the earliest hominin occupations in southwestern France.

Analysis of Aurignacian interstratification at the Chatelperronian-type site and implications for the behavioral modernity of Neandertals.

The Châtelperronian is a Neandertal-associated archeological culture featuring ornaments and decorated bone tools. It is often suggested that such symbolic items do not imply that Neandertals had modern cognition and stand instead for influences received from coeval, nearby early modern humans represented by the Aurignacian culture, whose precocity would be proven by stratigraphy and radiocarbon dates. The Grotte des Fées at Châtelperron (France) is the remaining case of such a potential Châtelperronian-Aurignacian contemporaneity, but reanalysis shows that its stratification is poor and unclear, the bone assemblage is carnivore-accumulated, the putative interstratified Aurignacian lens in level B4 is made up for the most part of Châtelperronian material, the upper part of the sequence is entirely disturbed, and the few Aurignacian items in levels B4-5 represent isolated intrusions into otherwise in situ Châtelperronian deposits. As elsewhere in southwestern Europe, this evidence confirms that the Aurignacian postdates the Châtelperronian and that the latter's cultural innovations are better explained as the Neandertals' independent development of behavioral modernity.
