These are two elongated Levallois flake / knifes made from typical dark Senonian flint from Le Moustier G.
The MTA assemblage from Le Moustier layer G (TL-Date: 50-55 k.a. BP) shows an ensemble that is characterized by a recurrent centripetal unidirectional Levallois concept with production of a series of unidirectional blanks. The Le Moustier G-ensemble is mainly composed of Senonian flint which displays gray to black colors. Elongated blanks are common and were often used for the production of backed knifes.
A recurrent unidirectional centripetal Levallois concept in S/W-France has been described at Fonseigner (upper parts of layer D; (TL-Date: 50-55 k.a. BP) and La Plane (layer I; ca. 75 k.a. BP), but also in level 9 of Bourgeois- Delaunay and in level 51 of Abri Suard (La Chaise-de-Vouthon, Charente) both dated to about 120 k.a. BP and attributed to a “Mousterien Typique”.
In the Levant at ca. 100-200 k.a. BP (Date depending on the dating technique) “Tabun-C” assemblages (Tabun Beds 18–26 , Qafzeh Level L/Units V–XXIV, Ras el-Kelb Railway Trench A–D and Tunnel Trench J–O) are also described as based on Levallois recurrent centripetal methods. Blanks in these ensembles tend to be relatively large and ovoid in shape.
In summary a unidirectional recurrent Levallois concept was used in S/W-France at least over a time span of 70000 years. The same concept appears to be prevalent in the Levant during OIS 5/6. If these trends belong to a continous “tradition” or are part of recurrent independent inventions remains open for discussion.
