The Neronian and the historical structure of cultural shifts from Middle to Upper Palaeolithic in Mediterranean France

The end of the Middle Palaeolithic period can be considered a key moment in the history of humanity, characterized by profound changes in traditional Palaeolithic societies. Whatever the reasons for this historical change, it seems well established that it took place within a particularly dynamic phase of these societies, when Upper Palaeolithic technical processes were already emerging. The analysis of recent Mousterian industries in Mediterranean France highlights certain points of inflection, which presage new ways of life. The analysis of key sites demonstrates important transformations within the last Neanderthal societies, with a gradual rearticulation of Mousterian technical systems around the production of blades and points and with profound changes in the relationship of the craftsman with his tools. Even if they are typical of the late Mousterian more generally, these technically distinctive industries have such distinct chronological, territorial and cultural characteristics that they can be referred to by a specific name, the Neronien (Neronian). Strati graphically speaking, this group of assemblages - at the crossroads of the Middle and Upper Palaeolithic - appears in some important regional sequences just before the appearance of the first true Upper Palaeolithic industries (the Protoaurignacian). However, this Neronian doesn't represent the end of the Middle Palaeolithic period in the Rhone valley. The final Mousterien of this region is actually marked by deep breakdowns of the traditional balances in the human groups. This second point of inflection could characterize a true destabilization of Mousterian societies. There is an interesting parallelism between the historical paths of the Castelperronian in the arch of the Massif Central and the Neronian in the RhC)ne valley. It also highlights the mosaic nature of the profound cultural changes that occurred at the end of the Middle Palaeolithic. (c) 2008 Elsevier Ltd. All rights reserved.
