description Publicationkeyboard_double_arrow_right Article 2017 Belgium, France EnglishPublisher:Humanities Commons Funded by:EC | PleisTechnoVar, ANR | Big DryEC| PleisTechnoVar ,ANR| Big DryAuthors: Leplongeon, Alice;Leplongeon, Alice;During the Nubia Salvage Campaign and the subsequent expeditions from the 1960's to the 1980's, numerous sites attributed to the Late Palaeolithic (~25-15 ka) were found in the Nile Valley, particularly in Nubia and Upper Egypt. This region is one of the few to have allowed human occupations during the dry Marine Isotope Stage 2 and is therefore key to understanding how human populations adapted to environmental changes at this time. This paper focuses on two sites located in Upper Egypt, excavated by the Combined Prehistoric Expedition: E71K18, attributed to the Afian industry and E71K20, attributed to the Silsilian industry. It aims to review the geomorphological and chronological evidence of the sites, present a technological analysis of the lithic assemblages in order to provide data that can be used in detailed comparative studies, which will allow discussion of technological variability in the Late Palaeolithic of the Nile Valley and its place within the regional context. The lithic analysis relies on the chaîne opératoire concept combined with an attribute analysis to allow quantification. This study (1) casts doubts on the chronology of E71K18 and related Afian industry, which could be older or younger than previously suggested, highlights (2) distinct technological characteristics for the Afian and the Silsilian, as well as (3) similar technological characteristics which allow to group them under a same broad techno-cultural complex, distinct from those north or south of the area. ispartof: PLOS ONE vol:12 issue:12 ispartof: location:United States status: published

The southern Caucasus region, with its rich cave-sites, has recently provided important results regarding this process. In this paper we report on the results of fieldwork in Bondi Cave, Western Georgia, providing a new radiocarbon chronology, stratigraphic observations, analyses of lithic technology and provenance, faunal and floral remains as well as paleoenvironmental data. The cave includes Middle Palaeolithic (ca, 45,000 ka cal. BP) cultural horizons and a long Upper Palaeolithic sequence (ca. 40,000–27,000 cal. BP from layer V to IV). A modern human tooth was found in layer Vb. We estimate its age at 39,000–35,800 Cal BP (95.4%), based on the Bayesian age model we built. If the context of the tooth is reliable, as we think it is, this would make it the oldest morphologically modern human in the Caucasus. Upper Palaeolithic hunting of tur and bison, as well as the collection of various plants including flax is attested. Mobile Upper Palaeolithic foragers inhabited the cave in generally cold and dry periods, but a mosaic of environments, including forests and meadows, was nonetheless available to them. The archaeological sequence of Bondi and adjacent sites indicates a substantial time gap between the Middle and Upper Palaeolithic occupations, thus disproving Neanderthal-AMH interaction in this area and lending support to a replacement scenario in the southern Caucasus, assuming of course that the Early Upper Palaeolithic (EUP) is related to the arrival of AMHs.

Toffolo; Aren M. Maeir; Jeffrey R. Chadwick; Elisabetta Boaretto;Michael B. Toffolo; Aren M. Maeir; Jeffrey R. Chadwick; Elisabetta Boaretto;The reliability of a radiocarbon date depends in part on the degree of precision and accuracy of the measurement. While analytical precision and accuracy can be improved by careful sample cleaning procedures and high laboratory standards, accuracy also depends upon the certainty to which the sample can be attributed to a specific material culture or event in the past. This might be questionable when based only on partial archaeological information. As a consequence, it is very difficult to date clear-cut chronological transitions within specific periods. This issue is particularly apparent in the case of Mediterranean Iron Age chronology, where 2 somewhat different perspectives are proposed, the “High Chronology” and the “Low Chronology,” which differ by ~50 yr. Here, we present the preliminary results of an ongoing project that aims to characterize Iron Age archaeological contexts from the eastern Mediterranean, and to identify those contexts that are suitable for dating, in order to improve the accuracy of 14C dates. This study involves the analysis of sediments by means of FTIR spectrometry, soil micromorphology, phytolith and phosphate extraction, all of which provide insights into the site-formation and postdepositional processes at the different sites under investigation. These techniques, applied at Tell es-Safi/Gath (Israel), enabled us to better identify a secure context for dating. DOI: 10.2458/azu_js_rc.v54i3–4.16172

The sedimentary sequence displays complex cultural, chronological and sedimentological histories that seem incongruent with one another. A first set of radiocarbon ages suggested a long sedimentological gap from the end of Marine Isotopic Stage (MIS) 3 to the mid-Holo-cene. Macroscopic observations suggest that the main sedimentological change does not coincide with the chronostratigraphic hiatus. The cultural sequence shows technological continuity with a late persistence of artifacts that are usually attributed to the Middle Stone Age into the younger parts of the stratigraphic sequence, yet become increasingly associated with lithic artifacts typically related to the Later Stone Age. While not a unique case, this combination of features is unusual in the Horn of Africa. In order to evaluate the possible implications of these observations, sedimentological analyses combined with optically stimulated luminescence (OSL) were conducted. The OSL data now extend the radiocarbon chronology up to 63 ± 7 ka; they also confirm the existence of the chronological gap between 24.8 ± 2.6 ka and 7.5 ± 0.3 ka. The sedimentological analyses suggest that the origin and mode of deposition were largely similar throughout the whole sequence, although the anthropic and faunal activities increased in the younger levels. Regional climatic records are used to support the sedimentological observations and interpretations. We discuss the implications of the sedimentological and dating analyses for understanding cultural processes in the region.

Toffolo; Eugenia Klein; Rivka Elbaum; Adam J. Aja; Daniel M. Master; Elisabetta Boaretto;International audience; The microstructure and chemical composition of eight faience beads from an early Iron Age (12th centuryBCE) assemblage found in the ancient city port of Ashkelon (Israel) are determined by means of FTIRspectrometry, pXRF, microRaman and SEM-EDS analysis. The results are compared with published dataof Egyptian and Near Eastern artifacts. Each sample exhibits a hue which is obtained by adding a specificcolorant to the glazing mixture. A new gray chalcopyrite-manganese-based colorant was identified.Cementation glazing was most likely used in the manufacturing process of the specimens analyzed,except for the blue bead, which is an Egyptian blue frit. The results suggest that these objects represent aunique assemblage, quite different from contemporary Egyptian and Near Eastern materials, and providenew information regarding the Iron Age faience evidence in the southern Levant.

The sedimentological analyses suggest that the origin and mode of deposition were largely similar throughout the whole sequence, although the anthropic and faunal activities increased in the younger levels. Regional climatic records are used to support the sedimentological observations and interpretations. We discuss the implications of the sedimentological and dating analyses for understanding cultural processes in the region.

Toffolo; Eugenia Klein; Rivka Elbaum; Adam J. Aja; Daniel M. Master; Elisabetta Boaretto;International audience; The microstructure and chemical composition of eight faience beads from an early Iron Age (12th centuryBCE) assemblage found in the ancient city port of Ashkelon (Israel) are determined by means of FTIRspectrometry, pXRF, microRaman and SEM-EDS analysis. The results are compared with published dataof Egyptian and Near Eastern artifacts. Each sample exhibits a hue which is obtained by adding a specificcolorant to the glazing mixture. A new gray chalcopyrite-manganese-based colorant was identified.Cementation glazing was most likely used in the manufacturing process of the specimens analyzed,except for the blue bead, which is an Egyptian blue frit. The results suggest that these objects represent aunique assemblage, quite different from contemporary Egyptian and Near Eastern materials, and providenew information regarding the Iron Age faience evidence in the southern Levant.
