This paper discusses the importance of the discovery of one déjeté Levallois tool from the surface of a dark grey and black patinated gravel terrace located ca. 500 m south-west of the Neolithic site of Sheri Khan Tarakai in the Bannu Basin (Khyber Pakhtunkhwa, Pakistan), and provides a detailed geomorphological description of the area where it was found. The Neolithic site rests on a large gravelly fan, at present terraced and dismembered by small seasonal streams. Scatters of black varnished pebbles, at the top of a thick ochre silt of possible alluvial origin, cover its surface. Amongst the numerous siliceous gravels forming the deposit, some are of a good quality chert, whose source can be found in the Tertiary Sulaiman Formation. The typological characteristics of the tool, the chert employed for its manufacture, its location and the presence of black patina on its cortex are all important elements that contribute to the definition of the Pleistocene period during which pebble terraces formed. The tool comes from a region where Middle Palaeolithic artefacts had never been found before, though the re-analysis of old collections would suggest their presence as far as the course of the Indus in Lower Sindh. Moreover, its discovery contributes to the study of the south-eastern spread of the Middle Palaeolithic Levallois technique, an important topic that still needs to be fully understood.
