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 Chaˆ telperronian 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.
