Abstract: This paper explores the impact of major glacial/interglacial paleohydrologic variations in the Middle-Paleolithic Levant on hominin migration and occupation. The climatic reconstruction is based primarily on the most straight-forward paleohydrologic records recently published. These terrestrial proxies convey direct paleoenvironmental signals of effective precipitation and aquifer recharge. The two main proxies are temporal changes of terminal lake levels in the Dead Sea basin and periods of deposition or non-deposition of speleothems. Other records, such as stable isotopes, if interpreted correctly, correspond well with these two direct proxies. All the records consistently indicate that the last two glacial periods in the central Levant were generally wet and cool, while the last two interglacials were dry and warm, so more water was available for the ecosystem and thus hominins during glacial periods than during interglacials. Some proxies indicate that the higher precipitation/evaporation ratio during glacial periods involved higher precipitation rather than only reduced evaporation. Beyond the general mean glacial/interglacial climate suggested here, variations occurred at all temporal scales throughout glacial or interglacial periods. In the Sahara-Negev arid barrier, moister conditions occurred during Marine Isotope Stage (MIS) 6a-5e, when Anatomically Modern Humans apparently migrated out of Africa. We suggest that this migration, as well as the later Neanderthal expansion from Southeast Europe or the Anatolian plateau into the Levant during early MIS 4, could be facilitated by the observed major climatic variations.

Abstract: This paper considers the recent radiometric dating (14C-AMS, TL, ESR) of 76 late Middle and early Upper Paleolithic samples from Ortvale Klde Rockshelter, located in the Republic of Georgia. We present a critical evaluation of each date based on its stratigraphic and archaeological context, its pretreatment and contamination history, and its resulting accuracy and precision, the goal being to establish a sound chronology for the site. Only by systematically identifying aberrant dates within a data set and isolating them from further analysis can we hope to understand cultural and biological phenomena on an accurate temporal scale. Based on the strict discard protocol outlined here, we omit 25% of the dated samples from the analysis. The remaining data speak to the lengthy tenure of Neandertals in the region, but also to their relatively rapid demise and the establishment of modern human populations ∼38–34ka 14C BP (42–39kacalBPHulu). We compare these chronometric data with those from the neighboring sites of Bronze and Dzudzuana caves, as well as Mezmaiskaya Cave, located in the northern Caucasus. While the lack of key contextual information limit our ability to subject these other data sets to the same critical evaluation procedure, they provide the first interregional temporal assessment of the Middle to Upper Paleolithic “transition,” the results of which suggest an initial expansion of modern humans into the southern Caucasus followed by expansion along the Black Sea coast and into the northern Caucasus.

Prior to the establishment of farming communities direct physical evidence for human conflict was rarely reported from archaeological contexts. Here we present a case of an Early Natufian (14.500–13.000 cal B.P.) projectile, classified as Helwan lunate, embedded inside the seventh or eighth thoracic vertebra sequence of a mature middle age adult male. Due to calcareous concretion four vertebras were still in anatomical connection when uncovered by F. Turville-Petre, during his excavations at Kebara cave (Mt. Carmel) in 1931.

A study of the mineralogy and phytolith assemblages of hearths and their associated sediments in Hayonim Cave, Israel, shows that wood ash is a major component of the sediments of both the Natufian (approximately 12,000 bp ) and the Mousterian deposits (approximately 100 to 250,000 bp ). Interestingly, phytolith analyses show that in the Natufian deposits grasses are the second most abundant form of vegetation preserved, whereas in the Mousterian deposits leaves of dicotyledonous plants are the second most abundant form of vegetation preserved. Significant differences were repeatedly observed in phytolith assemblages from closely associated but different stratigraphic layers, showing that vertical mixing of intact sediments is not intensive, and that there was a diverse input of vegetation over relatively short time periods. No consistent differences were observed in the mineralogy and the phytolith assemblages between hearths and their associated sediments. Both contain abundant ash components. This study demonstrates that quantitative analyses of phytoliths together with mineralogical analyses, can provide much information on the use of plants for fuel and other purposes by the cave occupants.

The long archeological sequence exposed during our renewed excavations in Hayonim Cave sheds new light on the striking technological changes observed at the boundary between the Acheulo-Yabrudian (end of the Lower Paleolithic) and Early Middle Paleolithic in the Levant, as well as on their meaning in terms of population movements. The recent, as yet unpublished, technological studies highlight a clear technological break between these two entities. In Hayonim, the Acheulo-Yabrudian assemblages found at the bottom of the archeological sequence display the specific combination of bifacial shaping and the production of thick, often cortical, flakes frequently shaped into scrapers by Quina retouch. Neither of these lithic production systems is observed in the succeeding Levantine Middle Paleolithic assemblages. In contrast, the Early Middle Paleolithic is characterized by the expansion and diversification of the Levallois production system in its full-fledged form, the emergence of a specific Laminar technology, and a high proportion of retouched tools made on elongated blanks (points and blades). These technological features are unknown in the previous Acheulo-Yabrudian assemblages in the cave. Based on this information, we attempt to determine if the observed changes in stone tool production strategies resulted from an autochthonous development or a dispersal out of Africa.

Abstract: The archaeological site of ‘Ubeidiya provides a unique, rich faunal assemblage, as well as evidence for the presence of early hominins in the Levant. Paleontological analysis of the faunal community is pertinent to understanding the biochronology and the timing of hominin dispersal events from Africa to Eurasia. This study presents the large carnivores from the recent seasons of excavations (1989–1999) and previously published material. Based on biochronological correlations of the carnivore guild and paloemagnetism, the age of the site is 1.5–1.2Ma. This date is 100–200,000 years earlier than previous estimates. Of specific importance is the presence of the African origin saber tooth Megantereon cf. M. whitei and the Eurasian origin canids Canis moschbachensis and Lycaon lycoanoides.

Abstract: Resource intensification is often viewed as a precursor to sedentism and thereby to agriculture. Late Upper Paleolithic sites in China are also seen as important precursors to the beginnings of sedentism and agriculture, but few faunal assemblages have been studied in detail and therefore little is known of pre-Neolithic economies in the region. A large faunal sample from a key site for early pottery and possible rice collection sheds light on subsistence strategies at the end of the Paleolithic. We apply an array of taphonomic analyses to the mammal remains to investigate the extent to which carcasses were processed for within-bone nutrients, which we see as a possible indicator of resource intensification. Determining if this is a regional trend, and/or represents diachronic change in subsistence strategies, will depend on the availability of comparative data in the future. [Copyright &y& Elsevier]

Abstract: Qafzeh Cave, the burial grounds of several anatomically modern humans, producers of Mousterian industry, yielded archaeological evidence reflecting their modern behavior. Dated to 92kaBP, the lower layers at the site contained a series of hearths, several human graves, flint artifacts, animal bones, a collection of sea shells, lumps of red ochre, and an incised cortical flake. The marine shells were recovered from layers earlier than most of the graves except for one burial. The shells were collected and brought from the Mediterranean Sea shore some 35km away, and are complete Glycymeris bivalves, naturally perforated. Several valves bear traces of having been strung, and a few had ochre stains on them. [Copyright &y& Elsevier]

Abstract: This paper reconstructs the vegetal diet of the Middle Paleolithic humans in Kebara cave (Mt. Carmel, Israel) on the basis of a large collection of charred seeds and other vegetal food remains uncovered during the excavations. The human choices of mainly legumes reflects the gathering activities during springtime when often the common hunted species (gazelle and fallow deer) were fat depleted. Minor fall activities are indicated by the collection of acorns and pistachio nuts. This vegetal dietary information adds another aspect to the range of subsistence activities of the late Mousterian occupants of Kebara cave, and sheds further light on the semi-sedentary use of the cave as revealed from analysis of animal bones.

The mineral components of the sediments that accumulate in an archaeological site constitute a potentially rich source of information on the diagenesis, and in turn the archaeology of the site. This detailed three-dimensional study of the mineral assemblages in mainly the Mousterian sediments of Hayonim Cave incorporates more than 2100 infrared analyses performed on-site during the excavation, as well as diverse analyses in the laboratory. Three major mineral assemblages are identified: the calcite-dahllite (CD) assemblage, the assemblage comprising mainly montgomeryite, leucophosphite and siliceous aggregates (LMVS), and a highly altered sediment in which the clays have broken down and silica was released. The boundaries between these assemblages were mapped in detail. The overall picture is one of extreme heterogeneity with sharp variations occurring over distances of a few centimetres. The relation between the CD and LMVS assemblages shows that it is a product of post-depositional diagenesis, whereas the altered clay assemblage formed beneath an erosional unconformity. The CD and LMVS assemblages were derived primarily from an accumulation several metres thick of ash deposits produced by humans. Ash is thus shown to be a major component of the sediments of this cave. The distribution of the CD assemblage reflects to a large extent the locations of two active springs/seepages in the cave. The distribution of the CD assemblage also faithfully maps the distribution of bones in the cave, showing that their distribution is a function of preservational conditions and not human activities (Stineret al ., 2001). The conditions that produced the erosional unconformity, also resulted in severe alteration of the clays and other mineral components of these sediments. The erosion process and the fact that the thickness of this altered zone decreases towards the centre of the cave, indicates that the diagenetic driving force was probably climatic. The three-dimensional distributions of the mineral assemblages have a direct bearing on the dating of the cave by thermoluminescence and electron spin resonance. [Copyright &y& Elsevier]

Global cooling during the Last Glacial Maximum (LGM) posed significant challenges to peoples living in northern Eurasia. Using micromorphology, pollen and non-pollen palynomorphs (NPP), and faunal analyses, this study reconstructs the local paleoenvironmental contexts of repeated ephemeral occupations at Shizitan 29 in Shanxi Province, North China, across the LGM, from ca . 28 to 18 Ka cal BP, followed by a gap until a final occupation ca .13.5 Ka cal BP. Among the significant finds at Shizitan 29 are remains of 285 hearths and a rich lithic assemblage that contains the earliest radiocarbon-dated evidence for microblades in China, appearing first in Layer 7. The environmental data show that the low mountains and tributary river valleys of the Yellow River in the Loess Plateau provided abundant sources of water and food in spite of environmental fluctuations. Microblade-producing groups repeatedly visiting this locality survived severe climate change by making use of fire, selective herbivore hunting, processing plant foods with grinding stones, and symbolic ornamentation such as ostrich shell beads. NPP data also indicate the potential presence of flax and other fiber processing. The Shizitan 29 data demonstrate how humans adapted to challenging local conditions throughout the LGM, allowing them to stay within this northerly region without migrating to warmer southern latitudes.

Abstract: The study comprises an experimentally based investigation of interaction between temporal change in the morphology of microlithic tools and transformations in projectile technology during the Late Pleistocene in the Levant. Archery experiments with differently designed arrows fitted with various types of microliths representing subsequent Epipaleolithic cultures of the Levant allowed analyzing performance abilities of the arrows, identifying projectile damage types characteristic of particular hafting modes, detecting factors influencing the frequency of projectile damage and estimating the frequency of projectile damage expected to be found in archaeological samples. The data obtained through the experiments applied in the analysis of the archaeological microliths from Geometric Kebaran and Natufian sites in Israel indicate different approaches to the design of projectiles fitted with microliths characteristic for these cultures. The shift in design, associated with such important economic and social transformations as transition to sedentary settlements and a broad-spectrum economy, may reflect a demand for light, flexible and efficient projectile weapons requiring low time and labor investment for preparation and retooling. The use of such efficient weapons in conditions of growing population density and restricted areas available for Natufian hunter–gatherers can be considered as one of the factors that could have affected the subsequent transition to food production that took place in the early Holocene.

Situated at the crossroads of Africa and Eurasia, the Levant is a crucial region for understanding the origins and spread of Upper Paleolithic (UP) traditions associated with the spread of modern humans. Of the two local Early Upper Paleolithic technocomplexes, the Ahmarian and the Levantine Aurignacian, the latter appears to be unique in the endemic UP sequence, exhibiting greater similarity to the West European 'classic' Aurignacian than to the local preceding and proceeding UP entities. Previous publications have mostly focused on the similarities between the two lithic industries and less on studies conducted on Levantine Aurignacian bone tools and ornaments. Here, we present an archaeozoological, technological and use-wear study of ornaments on animal teeth from the Levantine Aurignacian layers at Manot and Hayonim caves (the Galilee, Israel). The selection of taxa, the choice of teeth, the mode of modification, and the use-wear analysis exhibit clear similarities with the European Aurignacian. This, with the technology of the osseous raw material exploitation, the presence of antler simple-base points, and some lithic typotechnological features, suggest a link between the symbolic spheres of the Levantine and the European Aurignacian cultural entities. Such similarity also supports some contribution of European Aurignacians groups to the local cultural entities, intermingling with the local material culture features. [ABSTRACT FROM AUTHOR]

Abstract: Observations pertaining to particular stages of the lithic chaîne opératoire, or reconstructions of the entire operational sequence at a particular site, can be used to develop a detailed understanding of past human cognitive capabilities, technological sophistication, mobility, and land use. The “reduction sequence” is a specific stage of the chaîne opératoire that many archaeologists have attempted to measure. Many of these attempts fail to recognize that “reduction” is a three-dimensional process, and thus should be measured with an appropriate three-dimensional unit: volume. This paper presents a new methodology for measuring and defining reduction in unifacial stone tools that reconstructs the original volume of a modified blank, allowing a realistic percentage of volume loss to be calculated. This new method is fast, precise, and very accurate. [Copyright &y& Elsevier]

A sample of 76 bifacial lithic artifacts from the Sultanian assemblage at the Netiv Hagdud site (9900–9600 BP; American School of Prehistoric Research Bulletin 43, 1997) was examined for microwear and technological traces in order to determine the function of ground and flaked bifacial tools used during the PPNA period. Standardized axe types (flint tranchet axes and polished stone axes made of coarser-grained materials) are among the technological, typological, and functional innovations of the Sultanian culture. The ground stone celts do not seem to have been used as tools, but 78% of the flaked bifacial tools and 27% of the tranchet axe spalls in the microwear sample were used. Most (85%) of the utilized bifacial tools in the sample were used to work wood, and 91% of the utilized axe spalls had woodworking traces. In this article, methods of distinguishing woodworking tools from chipped stone hoes and scrapers are presented, and the significance of the evidence for light woodworking or carpentry at Netiv Hagdud and early Neolithic sites in the Levant is discussed.

A series of radiocarbon dates systematically obtained from bone and charcoal samples from the stratigraphic sequence of O¨ku¨zini Cave has been analyzed in conjunction with stratigraphic and archaeological data to interpret the rates and processes of deposition and human occupation of the cave during the Epipaleolithic of southwest Turkey. AMS dates obtained on the charcoal series reveal the existence of three stratigraphic gaps. Sedimentation rates for the deposits are evaluated in relation to radiometric determinations, the nature and origin of sediment accumulation, the structure of the faunal and lithic assemblages and the changing nature of human occupation of the cave. A hypothesis is proposed to explain the processes and rates of sedimentation, including the three gaps revealed by the radiometric series. One of our aims is to caution against interpretations of cultural evolution directly linked to sedimentary rates for which the variation is not immediately evident during excavation, but which requires a more critical analysis, as we have had the opportunity to do at O¨ku¨zini.

The site of ‘Ubeidiya is located in the Jordan Valley, Israel and has been biochronologically dated to 1·5 m.y.a. It exhibits large lithic and faunal assemblages. Previous published hominid material includes a molar (UB 1701) and I2 (UB 1700). A recent review of the faunal material from previous excavations has revealed a highly worn hominid right lateral lower incisor (UB 335). The tooth was found in situ in the Lower Pleistocene deposits of stratum I-26a, which is comprised of sand and conglomerates of flint, limestone and basalt indicative of a pebbled lakeshore environment. Taphonomic analysis of the macromammal assemblage indicates high-energy fluvial transport. Paleoecological reconstruction suggests a large woodland fauna with a small percent of open steppe species.UB 335 did not differ significantly from the Lower Pleistocene hominid and modern populations but did differ significantly from all other fossil populations. Two-tailed Student t -test and single classification Model II ANOVA of the buccolingual diameter did not distinguish between Lower Pleistocene species: Homo habilis, H. ergaster and H. cf. erectus. Thus, UB 335 can be identified as a Lower Pleistocene hominid although it cannot be securely assigned to any particular species within that time frame. The current date of the ‘Ubeidiya deposits and the location of the site within the Levantine corridor suggests a tenative identification as H. ergaster. [Copyright &y& Elsevier]
