but rather a rare cordiform, 5 cm long scraper with scalar retouche on a dihedral thick flake from a Quina ensemble from the Carrière Chaumette in the Rhone Valley (http://www.aggsbach.de/2010/12/quina-scrapers-from-the-carriere-chaumette/). It is not a Quinson point sensu strictu, because it bears retouch only on one edge. But do you really think that Neanderthals used such categories?
“The Quinson points mainly correspond to a particular morphology characterised by a triangular section, at least near the apex (“trihedral points”). In most of the cases the overall shape actually does not show three faces, more or less comparable in size, but only two faces, one of them being dihedral (at least in the distal part), with the dihedron ridge along the symmetry axis. The latter face is not retouched, while the former (flat face) bears retouch on both the edges, but not necessarily all along (partial retouch)” (GAGNEPAIN 2006).
Such artifacts were made on thick dihedral or pentagonal flakes from an oportunistic, Quina or Dicoid chaine operatoire.
Quinson points sensu strictu occur in several sites in Europe as well as in Asia; they mostly belong to assemblages related to the Lower Palaeolithic or Early Middle Palaeolithic and dating to the Middle Pleistocene. Some of the most significant examples come from La Micoque, Terra Amata , Arago at Tautavel in France, Visogliano and Venosa-Loreto in Italy, Bilzingleben II in Germany, Kudaro I in Georgia, Evron and Tabun E in Israel, and even Zhoukoudianin China.
However they also occur in the Upper Pleistocene of Central Europe (Kulna in Moravia), Western Europe, especially in the Charentian Mousterian or typical Mousterian of Southern France: Fontmaure, Comte , La Crouzade, l’Hortus , as well as in Spain at Cueva Morin and El Castillo or in Italy in the Guattari cave
