Les matières premières,la technologie lithique et les stratégies d’occupation dans le site du Pléistocène moyen de Covacha de los Zarpazos (gisement de Galería,Sierra de Atapuerca,Espagne)

Variability is one of the most debated topics in lithic technology studies. For the Middle Pleistocene period, this debate has specifically focused on the significance of large cutting tools such as handaxes and cleavers. This paper presents the stone tool assemblage from Covacha de los Zarpazos site, included in the Galería complex at Sierra de Atapuerca (Burgos, Spain). We analyse the management of lithic raw materials, the reduction sequences identified, and the morphological variation in the shape of large cutting tools. The results show that raw materials play an important role in the final variability of tool shape, although they do not represent any real constraint. However, what determines the main variability of a whole lithic assemblage is the occupation strategy and the specific activities carried out in a given site.     

Apport des grands mammifères de la grotte du Vallonnet (Roquebrune-Cap-Martin, Alpes-Maritimes, France) à la connaissance du cadre biochronologique de la seconde moitié du Pléistocène inférieur d'Europe

The large mammals of Vallonnet cave, found into a level contemporary of Jaramillo event, are characteristics of the second half of the Lower Pleistocene. Some differences with the faunas of Fuente Nueva 3 and Barranco Leon, in Spain, which datation is the middle of the Lower Pleistocene, show that Vallonnet is younger. On the other hand, the differences are clear with Soleilhac faunas, which datation is the beginning of the middle Pleistocene.     

Les faunes de grands mammifères de la Caune de l'Arago (Tautavel) dans le cadre biochronologique des faunes du Pléistocène moyen italien

The fossiliferous levels of Caune de l'Arago supply a useful tool to investigate the relationships between faunal renewals and climate changes in a restricted area during the Middle Pleistocene. On the other hand the Italian fossil assemblages of the middle Galerian testified changes of palaeoenvironmental conditions. A biochronologic and palaeoecologic comparison among large mammalian faunas of these quite different Mediterranean regions have been performed in the aim to value possible vicariance of taxa and differences of faunal renewal dynamic during the Middle Pleistocene. After the results of our analysis we can correlate the faunal assemblages from the “Complexe moyen, ensemble stratigraphique I”, “Complexe moyen, ensembles stratigraphiques II and III”, “Complexe supérieur, sols A and B” of Caune de L'Arago sedimentary succession with the Italian Isernia (middle Galerian), Fontana Ranuccio (late Galerian) and Torre in Pietra (early Aurelian) faunal units (FUs) respectively. The French faunal assemblages were characterised by the absence of browsers and, conversely, by the presence of boreal taxa, mainly grazers, that were rare or never occurred in Italy. Accordingly, at no one Italian faunal complex, as expected, we can find any indication of continental cold climatic condition as showed by the faunal complexes of the Caune de l'Arago. Nevertheless, the major climate changes characterising the Middle Pleistocene can be detected in both regions. During the span time of Isernia FU, the temperature was at its lowest and arid conditions prevailed, whereas during the following Fontana Ranuccio FU humidity and temperature increased, as is more evident in central Italy local faunas. Moreover, after the similarity analysis, the Visogliano local fauna (North-Eastern Italy) was more related to the French than to the Italian ones. During the late Middle Pleistocene (Torre in Pietra FU) a moderate faunal reconstruction can be detected in both regions. The renewal was linked to climatic modifications taking place in the Mediterranean area approximately around OIS 11/OIS 10 transition, when interstadials became progressively milder and average humidity increased.     

Biochronologie mammalienne du Quaternaire du Maroc atlantique, dans son cadre régional

Recent researches conducted in Morocco in the frame of the “Programme Casablanca” provide a firm ground to set up a biochronology of the Pliocene and Pleistocene based upon the succession of Mammalian faunas, thanks to the occurrence of well-dated landmarks, and despite very scarce absolute datations. The site of Lissasfa, dated to the Miocene-Pliocene boundary by rodents, testifies to important exchanges with Europe. That of Ahl al Oughlam yielded more than 100 vertebrate species. The evolutionary stages of its rodents, carnivores, bovids, Kolpochoerus, as well as the absence of Equus, allow us to refer it to the late Pliocene, at ca. 2.5 Ma. The Thomas and Oulad Hamida quarries in Casablanca cut through a unique succession of marine and continental levels going back to the lower Pleistocene, yielding the earliest evidence of human presence in Morocco. Later stages of this human occupation are documented by the Middle Pleistocene levels of these quarries, and by several other sites, most of which are also located in the Rabat-Casablanca region, thus confirming the importance of this coastal area in human history. However, the first chapter of this history in North-western Africa, at present illustrated by the sites of Aïn Hanech and Mansourah in Algeria, remains poorly documented in Morocco.     

Ostracodes et stratigraphie du néogène et du quaternaire méditerranéens

A stratigraphical chart of marine ostracoda from Lower Miocene to Recent is established. Selected species (approximatively 220) are those morphologicaly well characterized and known from different parts of the Mediterranean area. It appears that: • lower Miocene ostracodes are still poorly known; • specific diversity is high during the Tortonian and the Lower Messinian before the complete disappearance of marine Mediterranean species during the Upper Messinian évaporitic episodes; • during the early Pliocene, about half of the Upper Miocene marine species are reintroduced with the Atlantic waters; other species migrate for the first time in the Mediterranean Sea by the same way; • at the end of the Pliocene or at the beginning of the Pleistocene several species known in Mediterranean since the Middle Miocene or before, such as Cytherella sp. gr. transversa and Ruggieria tetraptera, as well some “nordic guests” such as Hemicythere villosa and Cythere lutea, appear. This work is an opportunity to confirme a Late Miocene age for the Neogene of Skyros (Aegean Sea), to assign the “Upper Pliocene” of Terquem to the Lower Pleistocene and to refute the existence of a pliocene psychrosphere.     

Le bassin de l’homme du Pléistocène supérieur de Liujiang, Sud de la Chine : taille du corps, forme du corps et encéphalisation

The Late Pleistocene hominin fossil assemblage from Liujiang, South China include a fairly well-preserved cranium, a right os coxa, a complete sacrum, and other postcranial elements all belonging to a single individual. This rare discovery offers us a unique and singular opportunity in understanding this Late Pleistocene hominin's body proportion and relative cranial capacity (encephalization quotient [EQ]), and also pelvic morphology. Using the available right innominate and its mirror-imaged left side, we reconstruct Liujiang hominin's pelvis. Our analysis of the pelvis indicates that the Liujiang hominin has a very gracile and modern-like pelvic morphology. Indeed, all of the pelvic dimensions are smaller than those of other Pleistocene hominins. Moreover, the pelvic characteristics typical of Middle and Late Pleistocene hominins including Neanderthals cannot be identified in the Liujiang pelvis. In contrast, both Liujiang's metric and non-metric features indicate affinities to more recent human populations including our modern Chinese collections from Guangxi of south China. Further support of this assessment comes from the EQ value of 5.754 for Liujiang which is closer to Minatogawa 2 and modern Chinese populations than to Middle and Late Pleistocene fossil hominins. Our analysis of body shape shows that Liujiang has body proportion (i.e. body height relative to body breadth) typical of warm-adapted populations. Based on these findings, we reason that the modern physical characteristics of Liujiang may allude to a more recent geological age. Alternatively, its morphological “modernity” could also point to a much higher degree of skeletal variation within Late Pleistocene hominins in East Asia.     

La faune préhistorique de la région de Jungwon en Corée et la relation entre l'Homme et l'Animal

The Jungwon region, developed under the calcites deposit, contains 6 caves and 1 rock-shelter where we can find many animal bones. During the middle Pleistocene, some warm animals lived here and the number of species was increased in the course of the upper Pleistocene. In the upper Pleistocene, the young and old deer have been hunted as the main prey and they have been transported into the occupation area of prehistoric people. The cut-marks on the bones and the existence of bone tools reveal us their mode of subsistence.     

Comparaison de l'expression de certains caractères crâniens sur les hominidés chinois du Pléistocène récent et de l'Holocène (grotte supérieure de Zhoukoudian, sites de Longxian et de Yanqing)

The human remains recovered from “Grotte supérieure de Zhoukoudian” are the best-preserved Late Pleistocene human fossils in East Asia. For decades, as the representative of the Late Pleistocene human in East Asia, the Upper Cave skulls have been playing important role in the research of origins of modern Mongoloids and American Indians. With the advance of the origin and evolution of modern humans, more attention has been paid to the details and the mechanisms for the late Pleistocene human evolution and the formation of modern human populations. Both the origin and diversification of modern humans have been stressed. Some studies further trigger the debaters on the Upper Cave Man concerning its evolutionary level and its role in the formation of modern human populations in East Asia. To further explore these problems, we examined and compared 12 non-metric features on the 3 Late Pleistocene Upper Cave skulls and 162 Holocene individuals earthed from two archaeological sites of North China (Longxian and Yanqing). Our results indicate that 8 on the 12 features have different expression patterns between Upper Cave Man and recent Chinese leading the authors to believe that more primitive expressions appeared on the Upper Cave Man than on recent Chinese populations. Based on these findings, some problems on the intragroup variation in Late Pleistocene and Holocene populations are discussed.     

La gestion du quartz au Pléistocène moyen et supérieur. Trois exemples d’Europe Méridionale

Quartz is one of the main lithic resources employed along the Pleistocene for the manufacturing of tools. The abundance in all kind of environments leads to its frequent presence in archaeological sites. In spite of its suitability for knapping, the scarcity of specific researches on quartz industries has led to a view of this raw material as a second-rate resource, only used when flint was not available in the surroundings. Quite in opposition to this prejudice, the familiarity with the petrological and mechanical properties of the different varieties of quartz has led the Middle/Upper Pleistocene groups to a rational and differential exploitation of the available resources. There is a distinct selection of the varieties attending to the purposes of the exploitation and configuration. The patterns of exploitation of the cores are very standardized, based on longitudinal extractions and documenting the bipolar flaking technique. Moreover, when the raw material is of good quality, more sophisticated reduction methods such as the discoidal or the Levallois may be employed. On the other hand, for the purposes of configuration a clearly differential management of the raw material is attested: thus quartz is used for the small products (denticulates, side-scrapers, notches), while other stones (quartzite, porphyry and others) are devoted to the manufacturing of those tools demanding a more complex control of the elaboration (bifaces, cleavers, etc.). Either acting as the main lithic resource or as a complement to other raw materials, we can observe through the technological analysis of these lithic collections the great conceptual complexity depending on the needs to be fulfilled. Raw material quality allowing, the state-of-the-art technology of knapping can be applied to the quartz and, therefore, we should not understand its use as a consequence of environmental constrictions but rather as a result of the variability of the procurement strategies and management of lithic resources among the prehistoric communities.     

Évolution des grands Carnivores au Plio Pléistocène en Afrique et en Europe occidentale

This paper provides an overview of current knowledge of Plio Pleistocene Carnivora from Africa and Europe. In Plio Pleistocene times, many genera extend their ranges in Africa and Eurasia but their evolution are quite distinct in the two continents. In Africa, the modern carnivoran guild of sub saharian Africa originated in the early Pleistocene when took place extinction of archaic species. The north African fossil record is far from complete until the middle Pleistocene. In the middle and late Pleistocene, the modern carnivoran guild is associated with other elements: the simian jackal Canis simensis and two species of ursids Ursus arctos and Ursus deningeri which evolved towards Ursus spelaeus. Western European carnivore faunas show due to migration a constant turn-over of the species. Among felids, Panthera schaubi described by Viret (1954) and attributed to the genus Puma by Hemmer et al. (2004), is morphologically close to the snow leopard Panthera (Uncia) uncia. Canis etruscus is the sister group pf the clade including wolf and coyote and Canis arnensis is close to the African jackals. Ursus deningeri appears in the early Pleistocene together with two arctoid forms Ursus rodei and Ursus dolinensis that may be synonymous to Ursus arctos. The genus Hyaena is present in Europe in the middle and late Pleistocene.     

Macrauchenia patachonica Owen (Mammalia, Litopterna) de la région de São Raimundo Nonato (Piauí, Nordeste brésilien) et la diversité des Macraucheniidae pléistocènes

The São Raimundo Nonato (Piauí, Northeastern Brazil) area yielded about 50 Macraucheniidae remains. The study of this material and of other fossils from Northeastern Brazil (Paraíba, Pernambuco, Rio Grande do Norte) shows a great similarity to Macrauchenia patachonica as it was defined in Argentina, which is the most abundant of the three species pertaining to the genus. Thus the taxon Xenorhinotherium bahiense created in 1988 by Cartelle et Lessa for a material discovered in the Bahia State and assigned to use for all the Quaternary Litopterns from tropical Brazil appears to be no more than a junior synonym of it. M. patachonica seems to have occupied very varied biotopes from sea level up to a high of 4000 m, and from the cold Southern Patagonia to the Equatorial Venezuela. The species lived from the Middle Pleistocene up to the beginning of the Holocene.     

Reconstitution 3D par Computerized-tomography (CT) et endocrâne virtuel du crâne 5 du site de la Sima de Los Huesos (Atapuerca)

The 3d Ct reconstruction and virtual brain endocast of Cranium 5 from the site of “La Sima de los Huesos” (Atapuerca), allows us to get new information to increase the study and knowledge of Homo heidelbergensis population, and to compare this specimen with others in the fossil record, in order to understand the evolutionary process of the brain, focusing on the middle Pleistocene period. Furthermore, we can observe the changes this species (Homo heidelbergensis) has undergone, at least in Sima de los Huesos population making comparative studies with African and Asian middle Pleistocene specimens. We have used the new data to compare European Homo heidelbergensis represented by SH5 with Kabwe, a controversial specimen considered by some authors like the African Homo heidelbergensis representative, in order to establish the similarities and differences between both specimens.     

Pléistocène moyen et inférieur dans le Latium (Italie centrale)

Explorations and diggings of the Italian Institute of Human Palaeontology in Latium from 1950 to 2005, have brought out the following composite sequence: (1) for upper-middle Pleistocene of northern Latium: Travertine, gravels Acheulian-Mousterian transition, Riss. Homo (femur), Elephas antiquus, Hippopotamus, Bubalus murrensis, with upper Acheulian artefacts. (2) In middle Latium, middle Pleistocene: Volcanoclastic K-Ar 360 Ky.

Les vagues de peuplements humains au Pléistocène inférieur et moyen dans le bassin de la Loire moyenne, région Centre, France. Apports de l’étude des formations fluviatiles

Evidence of earliest human settlements had been searched in the alluvial formations laid down in the Middle Loire Basin. Many stepped sheets deposited during the successive interglacial-glacial quaternary cycles are studied in four valleys of the Loire tributaries: the Creuse, Indre, Cher and Loir rivers. These sandy remnants are systematically dated, using the Electron Spin Resonance method applied on bleached fluvial quartz. Five settlements which contain very Early Palaeolithic industries with Mode 1 technology were occupied during the Lower Pleistocene. About eighty sites with hand-axe assemblages are observed in Middle Pleistocene remnants; nine of these are described in this paper. The results theorize that the geographical center of France (47°N) would be reached by two influxes of human populations with an interval around 400 years, because major climatic pejorations, particularly at the end of the Lower Pleistocene. These two populations produced lithic industries with many differences in supply of raw materials and in techniques of striking. Not any typologic link had been observed joining the two industrial unities.     

La Grotte des Félins, site paléolithique du Pléistocène supérieur à Dar Bouazza (Maroc)

In the continental sediments filling a cave that developed in Middle Pleistocene deposits near Casablanca, Morocco, a very rich mammal fauna from the last climatic cycle was discovered. It was associated with a Middle Palaeolithic poor and atypical lithic assemblage manufactured on blocks and pebbles. The lower fossiliferous layer contained abundant carbonized remains of felids. Unfortunately, the site was destroyed by quarrying before adequate excavations could be carried out.     

L’industrie du site néandertalien de la grotte de Vindija (Croatie) : une révision des matières premières lithiques

The new analysis of the Middle Paleolithic industry from the cave Vindija (Croatia), showed a necessity of revision of the previous obtained data especially considering the use and origin of the raw materials (Kurtanjek and Marci, 1990). The results presented in this study pointed out some new aspects of interpretation. First, the significance of quartz in the Middle Paleolithic was underestimated. At the same time it is obvious that the major change in the use of the raw material was at the beginning of the Upper Paleolithic and of the Epigravettian, especially in the use of chert. The second change is registered in the use of chert between Middle and Upper Paleolithic: the chalky nodules of chert are more frequent in the Upper Paleolithic then the river pebbles used in the production of Middle Paleolithic artefacts. Still, the origin of this new raw material is at the moment unknown.     

Taxonomie du grand canidé de la grotte du Vallonnet (Roquebrune-Cap-Martin, Alpes-Maritimes, France)

The large canid of Vallonnet cave belongs to Xenocyon lycaonoides. Its remains are similar to the Xenocyon from Untermassfeld in Germany. X. Lycaonoides, and evoluated form of the Xenocyon genus, is characteristic of the second half of the Lower Pleistocene. The genus Xenocyon may be the ancestor of both Cuon and Lycaon.     

Étude analytique d’une clavicule complète de subadulte d’Homo antecessor (site de Gran Dolina, Sierra d’Atapuerca, Burgos, Espagne)

This study reports on the skeletal remains of an infant clavicle - specimen ATD6-37 - belonging to the Homo antecessor species, unearthed at Lower Pleistocene level TD6 of the Gran Dolina site (Sierra de Atapuerca). Studied alongside a further adult specimen - ATD6-50 -, they provide us with significant information on two key paleobiological aspects of these early humans: body shape and development. Based on the analytical results, the paper proposes a more accurate proportional method for determining age at death is applied to the fossilized infant clavicle under study. It goes on to hypothesize on postcranial growth and body shape and discusses morphological patterns and age at death of these early humans through comparisons with a wide range of infant dental samples and clavicular specimens in early and modern humans.     

Récentes découvertes de restes d'Hominidés fossiles en Chine du Sud

After the discovery of the controversial hominids and artefacts at the Longgupo site, three Early Pleistocene sites in the southern valleys of the Changjiang (Yangtze) were excavated from 1998 to 2000 in order to test the hypothesis that the hominids exist in China before 2 Ma. Three cheek teeth of Meganthropus palaeojavanicus, more than six hundreds pieces of artefacts of Mode 1 technology and thousands pieces of mammal fossils of Villafranchian age were unearthed in situ at the Longgudong Site in Hubei Province. More than 120 pieces of artefacts of Mode 1 technology and seven thousands pieces of mammal fossils of Villafranchian age were unearthed in situ at the Renzidong Site in Anhui Province. Although no new materials of hominids and artefacts were unearthed at the Yuanmou Man Site at Danawu in Yunnan Province, new materials of mammalian fauna confirm the horizon yielding the Yuanmou Man fossils is of the Early Pleistocene. These new discoveries imply that the appearance of hominids in China is very likely before 2 Ma. If the new report of 3 Ma artefact from Yuxian of the Nihewan Basin in northern China can be confirmed, it will be a strong support for the Continuity Theory.     

Les Ostracodes et le Quaternaire d’Aigion (golfe de Corinthe, Grèce)

The Upper Pleistocene and the Holocene of Aigion have delivered an abundant microfauna with 35 ostracode species. The Pleistocene from Aigion borehole generally provides Ostracodes from oligohaline environment with Cyprideis torosa, Candona angulata and Tyrrhenocythere amnicola while, in the Holocene, marine infralittoral species dominate with Cytheridea neapolitana, Carinocythereis whitei, Loxoconcha ovulata and Cytherois frequens. The marine sedimentation occurred at depth from some meters to some tens of meters. In the Aghios Constantinos section, the lagoonal marls are characterised by Euxinocythere schuldtae and a dwarf species of Xestoleberis. Then, a drastic environmental change occurs around the Pleistocene-Holocene boundary and presumably affected the whole Corinth gulf.
