During the 1990 survey by the Belgian Middle Egypt Prehistoric Project of Leuven University, we discovered a Palaeolithic site on top of a hill (figure 1). It was only during the 2003 campaign that we were able to visit the site again. As an important artefact concentration was found, we organised a simple survey with a single small trench. There was no time for a systematic excavation. The site proved to have suffered very extensive destruction by recent quarrying activities, but still some important observations could be made.

Figure 3. The profile with at its base a concentration of artefacts |
The surface of the hill is entirely disturbed by all kinds of diggings, apparently by local people in search for fine gravel for building purposes. The pits often reach the Pliocene silts below the gravel cover. The gravels are mainly oval light-brown chert cobbles of quite good knapping quality. Dump heaps are scattered over the whole hill surface. On the surface of the south-eastern part of the hill, there is a 80 sq. m badly disturbed concentration of large chert artefacts, which we sampled. Artefacts from this concentration bear the typical brown desert patina (figure 4) but some lack this patina suggesting that they have been removed recently from their original position inside the terrace deposits. Inside the concentration and below a recent dump heap, we cleared a profile in which some material could be found in apparently undisturbed position. The cleared surface is small, about 1.5 sq. m. The profile (figure 3) from top down is as follows: below the desert pavement with mainly numerous chert cobbles, a 20-30cm thick layer of reddish yellow fine sand (7.5YR 7/6) is present. The sand is quite well consolidated by calcite. Some rare chert cobble fragments are present. The deposit contains very fresh unpatinated artefacts (figure 3), mainly at its base but also scattered inside the sand. Some artefacts are in a horizontal position whereas others are placed vertically. Several artefacts were refitted in the field, suggesting that they did not undergo important postdepositional horizontal disturbances. The sand with the artefacts is resting on a somewhat more intensely coloured reddish yellow (5YR 6/6) granular quartz sand with a pavement of entirely fragmented chert cobbles. Fragmentation of the gravels from this horizon occurred in situ as the fragmented cobbles have preserved their original position. Below, there is an accumulation of chert cobbles belonging to the terrace deposits. At the location of the profile, terrace gravels form only a thin layer. The lithics |

The large cobbles of a light-brown good quality chert from the terrace deposits have been used as raw material. The prehistoric humans apparently preferred large oblong cobbles, 20 - 25cm in length. After decortication, they produced elongated blades from opposed platform cores (figure 5: 1-2, 4-5). Lateral preparation of the core was applied producing crests (figure 5: 7-8). The preparation consisted mainly of large flake removals whereas secondary fine preparation remained very restricted. Such an approach is also evident in the limited number of chips that were found in the profile survey. Apparently both opposed platforms were used alternatively in a similar way (figure 6: 10). The cores attest the production of very robust blades, most often with a thick bulb, which suggests the use of a hard hammer. Blades often have a rectangular shape (figure 5: 11; 6: 1-3, 8-12, 19-20), a result of the alternative flaking from both opposed platforms on cores that generally have parallel sides. Sometimes they have pointed distal ends (6: 4-5, 7, 15-16, 23). Blades were obtained in a continuous reduction without intermediate reshaping of the core as can be learned from the refitted blades (figure 6: 1-2). Blades are 10 to 20cm long, generally 2 to 4cm wide, often with a trapezoidal cross-section, and mostly 1 to 2cm thick. The butt is generally flat, sometimes dihedral or facetted. Levallois technology is missing with the exception of a single Nubian type 1 core in quartz (figure 7: 6) from the surface. Some flakes show some coincidental reminiscence of Nubian debitage (figure 7: 9) or even a more classical Levallois debitage (figure 7: 2 & 4). Tools have not been found, except a fragment of an unpatinated bifacial foliate (figure 7: 1). Fine regular retouches that 'smooth' the edges are absent. Interpretation and conclusion The presence of a blade technology might tempt us to correlate the assemblage from Al Tiwayrat with assemblages from the Upper Palaeolithic such as the Shuwikhatian (Vermeersch et al. 2000). The technical approach is however entirely different. The blade technology of Al Tiwayrat might seem to have a better fit with the Taramsan approach (Vermeersch et al. 1997, 2000). Still, we feel that the blade technology of Al Tiwayrat is technically less developed. |

Typologically, the foliate is reminiscent of the bifacial foliates that are present in early Nubian Complex assemblages such as those from Bir Tarfawi (Wendorf et al. 1993; Van Peer 1998) and from Taramsa 1 (Van Peer & Vermeersch in prep). Rose (2004) and Van Peer et al. (in press) have drawn attention to typological similarities between the early Nubian Complex and the sub-Saharan Middle Stone Age. The bifacial foliate from Al Tiwayrat, as well as others from early Nubian Complex assemblages, are most similar to those of the Lupemban industry, although they also occur in the Sangoan of western Africa (Clark 2001). Technologically as well, this assemblage evidences Lupemban features, such as the use of a blade reduction system, similar to the one documented in the Siszya Lupemban at Kalambo Falls (Clark 2001). In addition, Nubian Levallois methods for points begin to be modestly represented and this provides an obvious link with the early Nubian Complex. Although the lithic assemblage recovered from the exploitation site at Al Tiwayrat is small, we are tempted, also taking into account the stratigraphic data, to associate the lithic assemblage with a rather old Middle Palaeolithic or Middle Stone Age of Egypt and Northern Sudan (Van Peer et al. 2003). Typical for this assemblage is the association of a blade technology with foliates. Acknowledgments |
