During the 2011 season, the area was enlarged again to expose the remainder room and to verify the nature of this architectural complex. The excavations exposed further remains of the building and new parts of its southern flank. It became clear that this structure extended over a wide area. A third room was exposed, but its closing wall on the south is not yet located.
Sector F was also enlarged during the 2010 season, and several architectural elements were uncovered within the two uppermost layers, 0 and B (Fig. 3). A segment of a long wall, oriented east–west, was exposed (W228; preserved length 4.2 m). The wall was built of two rows of stones and mud bricks. Additional feature is a well-defined stony area (L235; Fig. 4), composed of numerous small stones. This stony area could be a large stone pit that was partially exposed. Four graves, primary and secondary, were located near W228 (Loci 230, 231, 232 and 233); Grave 233 was partially destroyed by Stone Pit 235.
At the end of the 2010 season, it became obvious that one of the goals during the 2011 season would be to extend the excavation area westward to expose the unexcavated part of Pit 235, to verify its nature and to uncover the entire length of W228 (Fig. 5).
The wall consisted of two sections; the western was built of two parallel rows of limestone; the two rows are preserved two courses high, although the southern row is higher (10–20 cm) than the northern one and the space between them is filled with earth and small stones. The collapse of brick material found on the floor (L238) indicates that the upper courses of W228 were built of bricks.
The eastern section of the wall is more poorly preserved and only its southern row survived; two large stone blocks mark its end.
Three additional features were exposed at the southwestern corner, including the remains of what seems to be an isolated wall (W240),and two postholes (L241 and L244). Another long wall, well preserved, is being exposed on the eastern side (W245).
The material culture is rich and consists of considerable amounts of flint artifacts, faunal remains, shells, and beads.
The analysis of the flint from the ongoing excavation has revealed a homogenous assemblage, tentatively attributed to the Pottery Neolithic period. The diagnostic tools are represented by various types of sickle blades with deep denticulation (Fig. 6) and large arrowheads dominated by ‘Amuq arrowheads (Fig. 7). These points differ in the shaping technique from the ‘Amuq points of the PPNB. Based on the techno-typological analysis, it is possible to date this assemblage to the Yarmukian culture. However, with the absence of certain tools, such as small arrowheads, and the existence of others that could be associated with earlier cultures, it is more likely to assign it to an earlier entity preceding the typical Early Pottery Neolithic assemblages. The primary analysis of a sample from the faunal assemblage indicates the dominance of cattle and pigs. The composition of wild game taxa shows foraging bouts to neighboring areas where boars may have been found. It is worth mentioning the absence of sheep compared to the presence of goats, although this is only a preliminary observation.
The results of the two last excavation seasons at Beisamoun demonstrate that part of the upper occupation layer at the site is undisturbed and the archaeological remains are well preserved. The architectural remains include a complex of multi-room structures, several walls and floors, hearths, pits and other industrial features. These are promising factors for future explorations of the earlier occupation at Beisamoun. The flint assemblage resembles the early stages of the Pottery Neolithic Period.
