Abstract

The site of Aïn Dfali is located in the south of Ouazzane city of, in the Northwest of the village Aïn Defali. This area is situated at the western end of the Gharb plain in the southern area of pre-Rif tables. The Quaternary formations are located on the right bank of the river Redat. The large hills, at the West of Aïn Dfali village, consist of alluvium gravel attributed to Early Quaternary. In the foothills, the Middle Quaternary takes place with an attenuated highlighted. The exploited raw material used to make the lithic industries, found on the site, consists mainly of quartzite with a choice of mid/big-sized blocks. The reduction sequences are not complete as demonstrated by the absence of preparation and small flakes. Debitage and shaping reduction sequences coexist in this site. The shaping is essentially represented by handaxes and chopper-cores. Handaxes are often shaped on one side and show significant cortical residues; they are shaped on flakes elongated and flattened cobbles. The flakes used as blanks are generally cortical. The chopper-cores are exploited by unifacial unipolar knapping (from 3 to 5 removals) and show a probably non-functional sinuous edge. The utilized methods of knapping are Levallois (recurrent and lineal), discoid bifacial and unifacial and SSDA. The SSDA method shows the exploitation of 2/4 knapping platforms by an unipolar method aimed at obtaining large/medium sized flakes with irregular shapes and often lateral cortical residues. Very few retouched blanks were found. The Levallois debitage is done on flat and rounded cobbles, the preparation of the Levallois surface is carried out by centripetal knapping and the debitage surfaces show the detachment of a preferential flake, with a round shape, or a recurrent (centripetal or unipolar) exploitation; also documented is the production of Levallois points. The discoid debitage is performed on rounded cobbles, it is mostly unifacial and it shows the preferential exploitation of a pronounced convexity or the alternating exploitation of two opposing convexities. The flakes obtained are thick and have a triangular/rectangular shape with converging negatives. The material found in Aïn Dfali is the result of a selective transport and is in the secondary position but allows to certify an important prehistoric Acheulian occupation in the region. © 2016 Elsevier Masson SAS
