Hayonim Cave
RENEWED EXCAVATIONS
A new series of excavations was conducted jointly by O. Bar-Yosef, L. Meignen, and B. Vandermeersch at Hayonim Cave from 1992 to 2000. The primary goal of the project was to uncover, study, and date the full Mousterian sequence, which, as discovered in the last season, lies above an Acheulo-Yabrudian layer of unknown depth. Only a few additional squares of the Natufian deposits were excavated during these years. Previous observations during the late 1970s suggested that the upper part of layer E contained an industry resembling the one from Qafzeh Cave (which was dated to c. 90,000 years ago). The material and lithics retrieved then in a deep sounding next to the western wall contained numerous elongated blanks similar to those of the Tabun D assemblage.
The areas excavated in 1992–2000 were the deep sounding, an area near the cave entrance, and the central area inside the main chamber. The excavations yielded well-preserved faunal remains and rich assemblages of stone tools. The systematic mineralogical mapping of the deposits at intervals of 5–10 cm demonstrates the uneven effects of diagenesis, mainly in a patch running diagonally across the central area. Along this patch, diagenesis affected the preservation of bones, but not the distribution of lithics. The well-defined hearth areas resemble those identified in Kebara Cave and micromorphological and geochemical analyses have shown that the majority of the sediments are anthropogenic in origin.
EXCAVATION RESULTS
STRATIGRAPHY. The exposed stratigraphy of Hayonim Cave can be summarized as follows:
Layer A. Layer A consists of ashy deposits c. 3 m thick. Radiocarbon dates, one coin from the second century CE, a small collection of Roman-Byzantine sherds, and a glass furnace suggest that the accumulation spans the period from c. 200 CE to the present.
Layer B. The Natufian complex includes a series of built rooms, graves, a kiln, domestic midden, and evidence for various activities including bone tool production. The built-up rooms stretch mainly across the illuminated part of the cave chamber, near the entrance. The thickness of this layer varies from 0.10–1.20 m. It is stratigraphically subdivided into five phases of building and refilling. On the basis of lithic typological comparisons, the main occupation took place during the Early Natufian period. It ended with an ephemeral use of the site dated to the Late Natufian period. While the overall age of the Natufian culture in the Levant ranges from 14,500 to 11,600
Layer C. A Kebaran deposit about 2.5 m thick, confined to the entrance of the cave, consists of loose, reddish, granular silt and clay, locally cemented with calcite and rich in bones and lithics. The sediments were a mixture of reworked deposits derived from the destruction of the Mousterian layers, especially at the base, and an accumulation from the Kebaran period, probably around 19,000–16,000
Layer D. Mostly confined to the central area, layer D is 0.35–0.55 m thick and composed of an ashy matrix with bone middens. It contains a rich lithic industry, and a few well-structured hearths. Radiocarbon dates indicate an age of 29,000–27,000
Layer E. Layer E consists predominantly of anthropogenic sediments including hearths, ash, and organic matter, but locally contains well-defined clay-rich geogenic lenses. The sediments are generally horizontal but dipping increases toward the rear of the cave, with inclinations to the north and northwest reflecting one or more sinkholes in the back of the cave. The bones were preserved in the central area, except for the diagonal patch (about 40–50 cm wide), and in the upper part of the deep sounding. The occurrence of travertine stalagmites in the upper part of layer E is related to a wetter period. The Mousterian industries in the upper layer E resemble the Tabun C-type Mousterian, while the lower layer E is generally similar to the Tabun D type. The thermoluminescence ages of lower layer E range from 130,000/150,000–180,000
Layer F. There is a clear nonconformity between the base of layer E and the top of layer F. The deposits of layer F are yellowish-brown, predominantly geogenic, and consist of extremely diagenetically altered clay, silica, and quartz silt. Except for the top part, the layer was mainly exposed in the deep sounding. Phosphatization is widespread in this layer and seems to have been the main cause for the dissolution of most of the bones. The assemblage is attributed to the Tabun D type on the basis of the dominance of elongated blanks produced by the Mousterian knappers. Preliminary thermoluminescence dates place this assemblage at around 220,000 years ago.
Layer G. Below a zone indicating stratigraphic unconformity, only the uppermost part of this layer, about 1 m thick, was exposed. The top levels are pinkish-gray, hard, gritty silt, rich in layered opaline seed coats. Below this is a massive unit consisting of mottled brown and yellow-brown silt and seed coats, but in much lower abundance than in the overlying layer. Some charcoal flecks and abundant bird gastroliths occur in this unit, along with traces of millimeter-sized grains of gray silt. A rich Acheulo-Yabrudian lithic industry with bifaces and Quina-type (thick) sidescrapers was uncovered. No dates are yet available for this layer but similar industries from Mount Carmel date to 350,000–270,000 years ago.
THE LITHIC INDUSTRIES. The new information concerning the lithic industries at Hayonim Cave focuses on lower layers E and F. The flint and chert nodules brought to the cave were retrieved from geological outcrops within a 10 km radius. Only a few pieces originated 20 km away, with very rare lithics from even further away (30–40 km). Most of the stone tools were produced on elongated blanks (Tabun D type) from essentially unidirectional cores, with limited evidence for bi-directional flaking. Core reduction is often Levallois in its technical concept of the volume of the nodule, resulting in a semi-prismatic core geometry close to that which characterizes the Upper Paleolithic blade industries. The blanks are classified as blades and elongated points. The retouched tools include elongated points, sidescrapers, and burins.
Assemblages similar to the Tabun D type are found at Tor Abu Sif and
THE FAUNAL ASSEMBLAGES. The faunal assemblages from the deep sequence of layers E and F consist mainly of gazelle, fallow deer, and aurochs, with minor quantities of wild boar, roe deer, rhinoceros, hare, some reptiles, and a few birds. There are numerous remains of tortoises.
CONCLUSIONS
The relatively small quantities of bones and the low densities of artifacts (larger than 2 cm) per cu m, versus the large assemblages of microvertebrates (which result from the activities of barn owls), as well as the thermoluminescence dates, lead to the conclusion that human occupation at Hayonim Cave was ephemeral during this long period. Even the hearths are often thinner when compared to later Mousterian sites such as Kebara; and instead of branches and trunks, the campers at Hayonim used small, dry branches. The suggested interpretation for these observations is that human groups were more mobile during the Early Mousterian period and overall population densities in the region were much lower than in later times.
