Sedimentology and stratigraphy of the Jordan River Dureijat archeological site reveal subtle late Pleistocene water-level changes at Lake Hula, Jordan Valley, Israel

The terminal Pleistocene Natufian Culture of the Levant is one of the best-documented cases of preagricultural sedentism in prehistory, thanks to the proliferation of durable architecture, burial grounds, and intensified socioeconomic practices. Hof Shahaf, located on the shore of Lake Kinneret in Israel, is a recently excavated Natufian site whose interpretation presents a conundrum. On the one hand, the site produced evidence of architecture, burial, and diverse subsistence practices, just like the rich and permanently occupied hamlets of this culture. On the other hand, it clearly diverged in the meager accumulation of artifacts (lithics and fauna) and an apparent absence of aquatic resource exploitation. Here, we aim to understand the nature of habitation at Hof Shahaf: whether it was a sedentary hamlet, an ephemeral residential camp, or a task-specific logistic locality. The latter two site types are not well documented in the Early Natufian of the Mediterranean climate zone. We provide a zooarchaeological and taphonomic account of the site, supplemented with lithic data, to investigate the paleoenvironment, subsistence, and site-occupation intensity, all against the backdrop of a specific setting (one of the lowest recorded lake stands). Our results indicate that the site primarily falls within a middle ground between classic sedentary hamlets and more specialized sites. It may have functioned as an ephemeral residential camp for foragers traveling to the Kinneret Basin for specific or seasonal tasks. Nevertheless, the site still held some significance, evidenced by the investment in building a large structure and burying the dead.

The Sea of Galilee is the one and only large freshwater or slightly oligohaline natural lake in the Levant, and it therefore represents an important aquatic habitat in the region that also provides invaluable ecosystem services for the local communities. To improve our knowledge of the lake’s ecosystem and the use of disarticulated ostracod valves and preserved carapaces, micro-crustacean remains commonly used in palaeolimnology and palaeoceanography, as proxies for palaeoenvironmental reconstructions, and to examine the post-mortem dispersal of ostracod remains, 68 surface-sediment samples were collected from the lake floor in 2012 and analysed for the ostracod assemblages. Both, the noded and smooth, forms of Cyprideis torosa dominate in the Sea of Galilee, with the former more abundant than the latter. Relatively abundant and found at half of the 68 sampling locations or more, are also Ilyocypris hartmanni, I. cf. nitida, Darwinula stevensoni and Neglecandona angulata. In addition, ten less abundant ostracod taxa were recorded in the lake. Of all 15 taxa recorded in our study, ten were apparently also recorded in a study of the Sea of Galilee’s ostracod fauna conducted already in the 1960s. The newly recorded five taxa are relatively rare, and they were mostly found in the region of the Jordan River delta or near the southeastern shore of the lake which were not included in the survey of the 1960s. Thus, there is no evidence for a significant change in the ostracod fauna of the lake over the last half-century. In comparison to the ostracod assemblage from a late Pleistocene archaeological excavation site at the southwestern margin of the lake, the assemblage from the recent survey is slightly less diverse, probably as a result of the long duration of ca. 5000 years integrated by the sedimentary section of the archaeological site and also due to nearby freshwater inflows from which valves and carapaces were probably washed to the site’s location. Our study also shows that ostracod valves and carapaces are typically relatively abundant in most of the surface-sediment samples collected from locations at 18 m or shallower. In contrast, very few valves and carapaces were recorded at depths greater than 18 m, which is a zone affected by seasonal anoxia in the Sea of Galilee. These few ostracod remains were apparently transported by currents and waves to the central, deeper part of the lake, but their low number shows that such post-mortem dispersal of ostracod remains is insignificant in the deeper part of the lake. Thus, our study provides support for palaeoenvironmental and palaeoclimate reconstructions based on ostracod records from single sediment cores obtained from depths unaffected by post-mortem transport and seasonal or permanent anoxia.
