The site of LuneryRosieres la-Terre-des-Sablons (Lunery, Cher, France) comprises early evidence of human occupation in mid-latitudes in Western Europe. It demonstrates hominin presence in the Loire River Basin during the Early Pleistocene at the transition between an interglacial stage and the beginning of the following glacial stage. Three archaeological levels sandwiched and associated with two diamicton levels deposited on the downcutting river floor indicate repeated temporary occupations. Lithic material yields evidence of simple and more complex core technologies on local Jurassic siliceous rocks and Oligocene millstone. Hominins availed of natural stone morphologies to produce flakes with limited preparation. Some cores show centripetal management and a partially prepared striking platform. The mean ESR age of 1175 ka ± 98 ka obtained on fluvial sediments overlying the archaeological levels could correspond to the transition between marine isotopic stages (MIS) 37 and 36, during the normal Cobb Mountain subchron, and in particular at the beginning of MIS 36. The Lunery site shows that hominins were capable of adapting to early glacial environmental conditions and adopting appropriate strategies for settling in mid-latitude zones. These areas cannot be considered as inhospitable at that time as Lunery lies at some distance from the forming ice cap. [ABSTRACT FROM AUTHOR]

The paper provides new data on the age and formation processes of Garba I (Melka Kunture, Upper Awash, Ethiopia). The site, one of the largest handaxe accumulations of the African Acheulean, was extensively excavated in the 1960s of the last century by J. Chavaillon but left largely unpublished. The chronology was also poorly constricted. Quartz grains dated through electron spin resonance (ESR) spectrometry now provide a minimum age of 538 ka for the archaeological layer. In addition, we make available new data allowing an updated interpretation of the stratigraphic sequence and spatial distribution, as well as a detailed taphonomic study of the lithic assemblage. Additional information on the archaeozoological and palaeobotanical record are integrated in the discussion. We conclude that the extensive accumulation of large cuttings tools (LCTs) is not the result of major sedimentary disturbance processes but rather the outcome of a distinct hominin behaviour, which possibly was not focused on the processing and consumption of large mammals. New research at Garba I allows new insights on the Acheulean sites with similar large accumulations of handaxes. Additionally, it contributes to a better understanding of the early Middle Pleistocene in Africa, an under-researched period of the Early Stone Age. [ABSTRACT FROM AUTHOR]

New Caledonia was, until recently, considered an old continental island harbouring a rich biota with outstanding Gondwanan relicts. However, deep marine sedimentation and tectonic evidence suggest complete submergence of the island during the latest Cretaceous to the Paleocene. Molecular phylogenies provide evidence for some deeply-diverging clades that may predate the Eocene and abundant post-Oligocene colonisation events. Extinction and colonization biases, as well as survival of some groups in refuges on neighbouring paleo-islands, may have obscured biogeographic trends over long time scales. Fossil data are therefore crucial for understanding the history of the New Caledonian biota, but occurrences are sparse and have received only limited attention. Here we describe five exceptional fossil assemblages that provide important new insights into New Caledonia's terrestrial paleobiota from three key time intervals: prior to the submersion of the island, following re-emergence, and prior to Pleistocene climatic shifts. These will be of major importance for elucidating changes in New Caledonia's floristic composition over time. [ABSTRACT FROM AUTHOR]

The Chauvet cave (UNESCO World Heritage site, France) is located in the Ardèche Gorge, a unique physical and cultural landscape. Its setting within the gorge—overlooking a meander cutoff containing a natural arch called the Pont d'Arc—is also remarkable. Investigating possible associations between sites' physical and cultural settings, chronologies of human occupation, and access conditions has become a major theme in archeological research. The present study aims to reconstruct the landscape of the Pont d'Arc meander cutoff during the Upper Paleolithic, when humans were present in the Chauvet Cave. We used uranium-series and electron spin resonance analyses to date the formation of the Pont d'Arc natural arch in the Combe d'Arc meander cutoff, near the Chauvet Cave. Results show that the meander became totally cutoff between 108 and 138 ka (95%). Hence, the natural arch formed before the Upper Paleolithic and the first known human presence in the Chauvet Cave, dated to 37 ka cal BP. These results allowed us to reconstruct a key part of the landscape surrounding the Chauvet Cave when it was being used by Upper-Paleolithic societies. [ABSTRACT FROM AUTHOR]

Decades of fieldwork in the Frosinone-Ceprano basin (Latin Valley, Latium, central Italy) have shed light on numerous open-air Lower Palaeolithic localities, delivering a human fossil calvarium, thousands of scattered faunal remains and a large collection of lithic industries, including core-and-flake type lithic series (mode 1) and Acheulean assemblages (mode 2). The continuously growing number of available geochronological data (obtained by 40Ar/39Ar on volcanic minerals, ESR/U-series on large mammal teeth and ESR on bleached fluvial quartz) allow today the construction of a reliable and precise chronological framework for the Lower Palaeolithic sites of this area of the Latin Valley. The archaeological horizons with bifaces all appear to belong to a relatively short Middle Pleistocene time range, between about 410 and 350 ka, coeval to the end of the interglacial MIS 11 and to the beginning of the following glacial MIS 10. The Acheulean tools are often associated with cores and flakes. Bifaces are mainly made on limestone, secondary flint and quartz. The archaeological corpus also yielded tools on fragments of large herbivore bones. Comparisons between technological strategies and palaeo-anthropological data at the global scale are now meaningful and enable us to decipher hominin behaviour at a more regional scale. Such careful work is becoming essential in the frame of the recent discoveries showing that the MIS 11–10 period was a pivotal period characterized by the appearance of several new archaeological features later associated with the Neanderthal lineage in Western Europe. We present here the first in-depth technological study of the Acheulean lithic corpus from the major archaeological sites from the Frosinone-Ceprano basin including the Campogrande localities (CG9 and CG10, intermediate and upper levels), Colle Avarone, Selvotta, Isoletta (level 4), Lademagne (upper and lower levels) and Masseria Castellone. For this work, we focus on biface shaping strategies and demonstrate technological features suggesting the existence of networks connecting the different human occupation sites. Technological data are compared with other penecontemporaneous Italian sites to discuss the hypotheses and characteristics of such early evidence of regionalization in Europe in this specific area of Central Italy. It seems to indicate that glacial conditions characterized by millennial rapid climatic oscillations could have been favourable to the development of specific vegetation propitious to human settlement in South-western Europe. European vegetation, as it drives the biomass availability for large herbivores, seems hence to have played a crucial role in the mobility and settlement of human groups. [ABSTRACT FROM AUTHOR]

Namibia is one of the southern African countries hosting the richest rock art heritage, with thousands of rock paintings. Although numerous studies investigated their distribution, style, and possible meaning, few are known about the materials used to perform these paintings. Our in situ study aimed at identifying the diversity of pigments and alterations of some rock paintings in the northwestern part of the Erongo (Namibia). It relies on extensive pXRF analyses of 35 figures from eight rock art sites of the area. Despite common limits of in situ pXRF analyses, the extensive number of figures analyzed and the original data treatment that we performed pioneered the first scientific analyses of the pigments from rock painting sites in the Erongo Mountains. Furthermore, the study also confirmed the presence of iron oxide pigments on a portion of wall exposed during the excavations carried out at the archeological site of Leopard Cave and of possibly datable alterations over several paintings, paving the way to future chronological analyses of past tradition of rock paintings in Central Namibia.

The dispersal of hominin groups with an Acheulian technology and associated bifacial tools into northern latitudes is central to the debate over the timing of the oldest human occupation of Europe. New evidence resulting from the rediscovery and the dating of the historic site of Moulin Quignon demonstrates that the first Acheulian occupation north of 50°N occurred around 670–650 ka ago. The new archaeological assemblage was discovered in a sequence of fluvial sands and gravels overlying the chalk bedrock at a relative height of 40 m above the present-day maximal incision of the Somme River and dated by ESR on quartz to early MIS 16. More than 260 flint artefacts were recovered, including large flakes, cores and five bifaces. This discovery pushes back the age of the oldest Acheulian occupation of north-western Europe by more than 100 ka and bridges the gap between the archaeological records of northern France and England. It also challenges hominin dispersal models in Europe showing that hominins using bifacial technology, such as Homo heidelbergensis, were probably able to overcome cold climate conditions as early as 670–650 ka ago and reasserts the importance of the Somme valley, where Prehistory was born at the end of the 19th century.

The study of geomagnetic excursions is key for understanding the behavior of the magnetic field of the Earth. In this paper, we present the geomagnetic record in a 2.29-m-long continuous core sampled in a flowstone in Liguria (Italy) and dated to the Lower Brunhes. The cored flowstone developed from Marine Isotopic Stage (MIS) 13 to MIS 7, according to 21 U-series dates. The mean growth rate is closely related to glacial and interglacial isotopic stages. Magnetic remanence was measured using u-channel and deconvolved. Four geomagnetic excursions were recorded at the same location, in a single flowstone, during interglacial MIS 11 and 13; Basura 1, 2, 3 and 4, at depths of 213 cm, 181, 160 and 92 cm, respectively. Due to the uncertainties of U-Th dating, the timing of the three events, namely Basura 1, 2 and 3 overlaps. The Basura 4 is well-dated to 417 + −7/8 ka and is clearly distinguishable from the others. It should therefore be considered as a possible excursion. [ABSTRACT FROM AUTHOR]
