Temporal nature and recycling of Upper Paleolithic artifacts: the burned tools from the Molí del Salt site (Vimbodí i Poblet,northeastern Spain)

Recent research in Paleolithic archeology has stressed the importance of temporal issues in assemblage interpretation. Archeological assemblages are temporal constructs, formed by the addition of an unknown number of depositional events. This temporal dimension is also evident at the artifactual level, since single artifacts may undergo different events of modification and/or uses over time. The recycling of previously discarded blanks for tool production is one of the best examples of the temporal nature of artifacts. The aim of this paper is to evaluate the importance of recycling in a Late Upper Paleolithic site, examining a type of artifact – burned tools – that has up to now been little used to approach this issue. Our results suggest that recycling was probably a significant component of Upper Paleolithic provisioning behavior, with important implications in site formation processes and the typological variability of assemblages. The expedient or curated character of recycling is also discussed.     

The Kulbulak Bladelet Tradition in The Upper Paleolithic of Central Asia

The article describes lithic industries of the Upper Paleolithic levels of Kulbulak, Uzbekistan, a key site in southwestern Central Asia based on materials from excavations at several sites in the western and northwestern Pamir– Tien Shan region (Kulbulak, Kyzyl-Alma-2, Dodekatym-2, and Shugnou). A new cultural and technological tradition is introduced, for which the authors suggest the name Kulbulakian. Its distinctive features are the bladelet technique and a microlithic set including backed pieces and triangular microliths. Stages in the evolution of the Kulbulakian tradition are reconstructed: origins, development, peak, and disappearance of the carinated technology. Industries belonging to this tradition have shaped the general appearance of the Upper Paleolithic in the area in question.     

Ground stone tool production and use in the Late Upper Palaeolithic: The evidence from Riparo Dalmeri (Venetian Prealps,Italy)

Abstract

The site of Riparo Dalmeri yielded numerous flint, bone, and shell artifacts, as well as faunal and botanical remains, which are evidence of the Late Upper Palaeolithic (or Late Epigravettian culture, ca. 16,000–12,000 cal b.p.) occupation of the Alps region. The importance of the site is related to the discovery of 267 stones painted with anthropomorphic, zoomorphic, and geometric designs. Here we report on ground stone tools from Riparo Dalmeri investigated by means of an integrated technofunctional and experimental approach to reconstruct their production and use. The results support the hypothesis that the ground stone artifacts were employed in specialized activities (e.g., hide treatment, flintknapping) as well as in the production of some of the painted stone artifacts.     

Technological successions in the Middle Stone Age sequence of Diepkloof Rock Shelter,Western Cape,South Africa

The southern African MSA comprises a series of phases of unique technological innovations that fuel current models on the evolutionary processes of Anatomically Modern Humans. However, the nature and variability of these technological phases remain poorly documented. This study reports on the previously unpublished sequence of Diepkloof Rock Shelter (South Africa) and investigates the main technological changes therein, particularly emphasizing the emergence, succession and disappearance of the Still Bay (SB) and the Howiesons Poort (HP). We argue for technological change that occurred at different rates and under the influence of variable driving factors. Our model implies that the SB and the HP are not related to the influx of new populations but have regionally specific origins. Unlike the other techno-complexes, the HP at Diepkloof is subdivided into different phases (Early, Intermediate and Late) but only the upper phases resemble the so-called “classic” HP. Finally, the technological sequence of Diepkloof questions the homogeneous picture which has been so far assumed for the southern African MSA and places emphasis on the importance of exploring long regional sequences.     

Discerning geological and geographical sources of Belgian Upper Paleolithic fluorites by rare earth elements and Sr-isotopic geochemistry

Fragments of fluorite (CaF₂) have been found at five Belgian Upper Paleolithic sites (Spy, Chaleux, Trou Magritte, Trou du Frontal and Verlaine caves), primarily of Magdalenian age. These sites are located in a large geographical area. The aim of this study is to isolate one or more primary sources where the mineral could have been quarried prehistorically, and hence try to deduce if time and effort were put into obtaining it, or if it was simply a useful nearby raw material. In order to achieve this objective, isotopic ⁸⁷Sr/⁸⁶Sr and REE ratios are used. A total of four archaeological samples from the Chaleux, Spy and Trou Magritte sites along with geological samples were analyzed (new results and data from the literature), obtained from two distinct stratigraphical units in Belgium: the Givetian limestones (mainly from the Calestian Band), and the Dinantian limestones.     

The first fossil avian egg from Brazil

Marsola, J.C.A., Grellet-Tinner, G., Montefeltro, F.C., Sayão, J.M., Hsiou, A.S. & Langer, M.C., 2014. The first fossil avian egg from Brazil. Alcheringa 38, 563–567. ISSN 0311-5518.

In contrast to the rich record of eggs from non-avian dinosaurs, complete eggs attributable to Mesozoic birds are relatively scarce. Nevertheless, several well-preserved specimens have been discovered over the last three decades revealing functional and phylogenetic characters that shed light on the breeding strategies of extinct birds. Here we report the first fossil avian egg from Brazil, which was discovered in Upper Cretaceous strata of São Paulo in the southeastern part of the country. The taxonomic identity and structural features of the biomineralized tissues were determined using a combination of Scanning Electron Microscopy, Wave Dispersion Energy analyses and Computed Tomography. These show that the 125.5-μm-thick shell of the 31.4?×?19.5?mm egg incorporates three structural layers of similar thickness with both prismatic and aprismatic boundaries. Close similarity between the Brazilian bird egg and those of enantiornithines from the Upper Cretaceous Bajo de la Carpa Formation (Río Colorado Subgroup) of Argentina advocates affinity with basal Ornithothoraces. Furthermore, coherency of their depositional contexts might imply a compatible preference for breeding and nesting environments.

Middle–Upper Jurassic marine gastropods from central Saudi Arabia

Ferrari, M., El-Hedeny, M., Zakhera, M., El-Sabbagh, A. & Al Farraj, S., May 2018. Middle?Upper Jurassic marine gastropods from central Saudi Arabia. Alcheringa.

A total of 68 gastropod specimens are reported from the Middle?Upper Jurassic sedimentary successions exposed at central Saudi Arabia. The studied material comes from the Tuwaiq Mountain and Hanifa formations at the Khashm al Qaddiyah, Dirab, Jabal al Abakkayn and Maáshabah sections. Thirteen species are identified, described and illustrated. Among them, a new Aporrhais species (A. sauditica sp. nov.) is introduced. In addition, two further possible new Pseudomelania species from the same strata are mentioned. Other members of the assemblage include Kosmomphalus? sp. aff. K. reticulatus Fischer, Bourguetia? sp. aff. B. saemanni (Oppel), Bourguetia? sp., Ampullospira sp., Globularia? sp. cf. G. bajociana Fischer, Purpuroidea sp. aff. P. glabra Morris and Lycett, Purpuroidea sp., Cossmannea sp. aff. C. desvoidyi (d’Orbigny), Cryptoplocus sp. aff. C. depressus (Voltz) and Actaeonina? sp. Stratigraphically, seven species of this gastropod assemblage were only reported from the Middle Jurassic, whereas the other six ones are extending from the Middle to the Upper Jurassic of the studied succession. As compared with their gastropod content, the Khashm al Qaddiyah represents the richest section (33 out of 68 specimens, 48.5%), whereas the Maáshabah section showed an impoverished gastropod assemblage (only three specimens, 4.4%). The species reported here show paleobiogeographical affinities with coeval gastropod assemblages from India, east Africa, Middle East (Israel, the Sinai of Egypt) and western Tethys. The identified species confirm three depositional settings: open shelf lagoon, shoal/fore-shoal and open marine environments. The lower degree of fragmentation, poor sorting and scarcity of abrasion indicate a parautochthonous faunal assemblage.

The changing identity of the Central European city: the case of Katowice

The issue of diverse identities imprinted on the urban landscape as the result of political changes and the struggle for power between different social and ethnic groups is analysed here using the example of Katowice, the capital and largest urban centre in Upper Silesia, Poland. Basing their conclusions on systematic investigation of the most important changes and features in the cityscape in five clearly distinct historical periods, the authors explore the conditions and mechanisms of the creation of the city’s symbolic landscape and its links with urban identity. They argue that Katowice represents a peculiar model of urban identity formation in Central and Eastern Europe that has to date not been researched in any depth, in which each successive historical period represents a rupture with the foregoing values and ideas and an attempt to make a new, lasting imprint on the material outlook of the city. The development of such a model of identity is the result of the complex interplay between the city’s changing geopolitical context and its economic and functional development path.     

Early Upper Paleolithic industries of Eastern Europe

Early Upper Paleolithic sites are known in various parts of Eastern Europe, but the two main concentrations of them are the Prut-Dniester basin and the middle Don. The flint industries are divided into archaeological cultures (cultural traditions), of which some show clear archaic features (Kostenki-Streletsian, Gorodtsovian, Brynzenian, etc.), while others have no Mousteroid characteristics (Spitsynian, Telmanian, etc.). Both types of culture coexisted throughout the Early Upper Paleolithic. In some cases, it is possible to trace genetic links between archaeological cultures and to follow the transition between the Middle and the Upper Paleolithic. The radiocarbon age of the oldest Upper Paleolithic sites in the Russian Plain is about 40,000 B.P., but some sites may be older. The Early Upper Paleolithic ended about 24,000–23,000 B.P. In the Crimea, the Middle-Upper Paleolithic transition appears to have taken place at about 20,000–18,000 B.P.     

The late Upper Paleolithic in Italy: An overview

Previous studies of the Italian late Upper Paleolithic, or Epigravettian, have been primarily chronostratigraphic and typological. Only recently has attention been paid to environmental and behavioral data. The Epigravettian covers some 10,000 years, from about 20,000 B.P. (beginning of the last Wurm stadial) to about 10,000 B.P. (end of Dryas III and beginning of the Holocene). Traditionally, it has been divided into three phases: Early (20,000–16,000 B.P.), Evolved (16,000–14,000 B.P.), and Final (14,000–10,000 B.P.). The Evolved and Final Epigravettian have five regional facies: northern Tyrrhenian, central and southern Tyrrhenian, northern and central Adriatic, southern Adriatic and Sicilian. After an extensive summary of the available environmental data and traditional artifact analyses, we illustrate the present status of more behaviorally oriented research and discusss the consistency of the subdivisions in space and time. Suggestions are made of possible directions for future research.
