L’exploitation non alimentaire des ressources animales pendant le Magdalénien au Nord-Est de la Peninsule Ibérique. L’exemple de la grotte du Parco (Alòs de Balaguer, Lleida, Espagne)

Parco cave, discovered in 1974, has yielded more than 50 objects fashioned of hard animal parts from levels dating to later phases of the Magdalenian. In the work described here, we have undertaken a technotypological analysis of this previously unstudied bone and antler assemblage. The osseous series from Parco are homogeneous and very similar to those from nearby sites of roughly the same time period; that is to say of the late Upper Magdalenian of the peninsular Mediterranean. The latter are composed primarily of hunting weapons dominated by antler projectile points, as well as eyed bone needles and a few shell ornaments. Technological analysis shows production in which there is a tight relationship between morphological type and raw material employed. The production schema saw the removal of blanks by means of groove and splinter technique, followed by shaping of pieces by scraping and finishing of them - in some cases by abrasion.     

Traces d’impacts de projectiles sur le gibier : résultats comparés des tirs expérimentaux à l’arc et au propulseur effectués au Cedarc (Treignes, Belgique) en 2003 et 2004

In 2003 and 2004, two series of projectile experiments were organized by P. Cattelain and ourselves at the CEDARC/Musée du Malgré-Tout (Treignes, Belgium). The experiments involved the use of two male ox calves and two female fallow deers as targets for bow and spearthrower shooting. Our main focus was a functional analysis of the antler projectile tips from the Upper Magdalenian layer of the Isturitz cave site (Pyrénées-Atlantiques, France). The study of the impact traces on the bones of the target animals was also included in the project; its results are presented here. The observation of these 127 traces led us to reconsider the nomenclature suggested by P. Morel, and to distinguish between three major traces: notches, punctures and perforations. Correlations appear between the nature of the trace and the shape of the bone (e.g., scapulae strongly associated to perforations), and the bone's mineral content: compared to adult long bones, immature long bones are much more easily perforated by projectile points, which usually remain firmly caught in them. However, our results do not show a clear distinction between the impact traces left by the bow and by the spearthrower.     

Nouvelles données sur l’évolution paléoclimatique de l’époque magdalénienne,d’après l’étude lithostratigraphique du Roc-aux-Sorciers (Angles-sur-l’Anglin,Vienne, France)

Situated a few kilometres from Angles-sur-Anglin (Vienne, France), the Roc-aux-Sorciers cave has yielded in 1927 and 1950 industry of the Middle and Upper Magdalenian periods. Our analyses of the sedimentary filling, dated from isotope stage 2, demonstrate the existence of two climatic sequences in the six ensembles defined during the excavations. A first sequence, at the base of the cave filling, corresponds to the occupation levels of the Middle Magdalenian and of the early Upper Magdalenian. At that time, the climate was globally cold and particularly humid, a conclusion that does not support Bastin's 1975 hypothesis on the oscillation of Angles-sur-Anglin, which postulates a mild and humid climate. In fact, the climate evolved progressively towards a slight warming from the base to the top of the stratigraphy. During the second sequence, corresponding to the occupation period of the Upper Magdalenian, the relatively stable climate was slightly warmer and quite humid. Stratigraphical and sedimentological data thus provide new information on the conditions under which the filling was deposited and on the palaeoclimatology of the Poitou-Charentes region during Magdalenian occupation.     

Additional evidence for bone technology in the southern African Middle Stone Age

Few Middle Stone Age sites have yielded convincing evidence for a complex bone technology, a behavior often associated with the emergence of modern cultures. Here, we review the published evidence for Middle Stone Age bone tools from southern Africa, analyze an additional nine bone artifacts recently recovered from Middle Stone Age levels at Blombos Cave, describe an unpublished bone tool from probable Middle Stone Age levels at Peers Cave, examine a single bone awl found at Blombosch Sands (an open site near Blombos Cave), and reappraise marked bone artifacts and a bone point recovered from Klasies River. To determine the chronological and cultural attribution of these artifacts, document bone-manufacturing techniques associated with the southern African MSA, and discuss the symbolic significance of the markings present on some of these objects we use (1) available contextual information; (2) morphometric comparison of Later Stone Age, Modern San, and purported Middle Stone Age projectile points; (3) analysis of the carbon/nitrogen content of bone tools and faunal remains from Peers and Blombos caves; and (4) microscopic analysis of traces of manufacture and use. Previously undescribed bone artifacts from Blombos Cave include a massive point manufactured on weathered bone, two complete awls and two awl tips manufactured on small-sized mammal and bird bone, a probable projectile point with a tang manufactured by knapping and scraping, a shaft fragment modified by percussion, used as retoucher and bearing a set of incised lines on the middle of the periosteal surface, and two fragments with possible engravings. The point from Peers Cave can be assigned to the Middle Stone Age and bears tiny markings reminiscent of those recorded on projectile points from Blombos and used as marks of ownership on San arrow points. The awl from Blombosch Sands and the bone point from Klasies River can be attributed to the Later Stone Age. Two notched objects from Klasies are attributed to the Middle Stone Age and interpreted as tools used on soft material; a third object bears possible deliberate symbolic engravings. Although low in number, the instances of bone artifacts attributable to the Middle Stone Age is increasing and demonstrates that the bone tools from Blombos Cave are not isolated instances. New discoveries of bone tools dating to this time period can be expected.     

Art mobilier magdalénien en matières dures animales de Moravie (République tchèque). Aspects technologique et stylistique

The Magdalenian techno-complex evolved in Western Europe and Central Europe between 17-12 kyr BP, concentrated in Spain on the Cantabrian Coast and in France in Pyrenees and Dordogne, in Central Europe in Poland and Moravia. In our study we analyse portable art on hard animal tissues from Moravian sites (Pekárna, K?í?ova, Rytí?ská), Czech Republic. Comparative material was provided by sites in South-western France (Laugerie, Basse, Enlène). The results of the technological, stylistic and typological comparisons confirm our hypothesis that the Magdalenian portable art from sites in Moravia belong to the Magdalenian techno-complex. The comparison of typological objects in Moravia, like decorated bone disc, pendants, Venus, bâton percé, spatule, shows that their variability is well in the range expected for techno-complex. The same technological pattern can be found between typological objects of spatule as a technology of decoupage but which is applied on different anatomical parts of animal raw material. We discussed the question about local origin of the objects. Technological comparison shows that engraving and bas-relief are more frequent in Moravia than in South-western France sites. This can be explained as a regional based preference of technology for expression of different subjects of mobile art, but also as a possible bias due to small sample size and differences in sampling of our studied objects. Engraving present similar technological characteristics that are featured in both areas. Design, like organization of space and size of the engraving, can be interpreted as an existence of contact between both groups and presence of one Magdalenian techno-complex.     

Shape variation in Aterian tanged tools and the origins of projectile technology: a morphometric perspective on stone tool function

Background

Recent findings suggest that the North African Middle Stone Age technocomplex known as the Aterian is both much older than previously assumed, and certainly associated with fossils exhibiting anatomically modern human morphology and behavior. The Aterian is defined by the presence of ‘tanged’ or ‘stemmed’ tools, which have been widely assumed to be among the earliest projectile weapon tips. The present study systematically investigates morphological variation in a large sample of Aterian tools to test the hypothesis that these tools were hafted and/or used as projectile weapons.

Methodology/Principal Findings

Both classical morphometrics and Elliptical Fourier Analysis of tool outlines are used to show that the shape variation in the sample exhibits size-dependent patterns consistent with a reduction of the tools from the tip down, with the tang remaining intact. Additionally, the process of reduction led to increasing side-to-side asymmetries as the tools got smaller. Finally, a comparison of shape-change trajectories between Aterian tools and Late Paleolithic arrowheads from the North German site of Stellmoor reveal significant differences in terms of the amount and location of the variation.

Conclusions/Significance

The patterns of size-dependent shape variation strongly support the functional hypothesis of Aterian tools as hafted knives or scrapers with alternating active edges, rather than as weapon tips. Nevertheless, the same morphological patterns are interpreted as one of the earliest evidences for a hafting modification, and for the successful combination of different raw materials (haft and stone tip) into one implement, in itself an important achievement in the evolution of hominin technologies.     

Paléolithique supérieur et Mésolithique en Méditerranée : cadre culturel

The origin of the Upper Palaeolithic around the Mediterranean was the result of the local evolution, particularly in the Near East and in the Lower Nile basin, and of the migration from this zone to South-Eastern and Central Europe. The Initial Upper Palaeolithic in the Near East belt was the effect of local evolution from the industries based on Levallois concept to the industries which developed leptolithic blade technologies. This evolution is well registered in multi-layer sites in the Syro-Palestinian belt (Emirian/Ahmarian), which was the starting point of the diffusion of these “transitional” industries in South-Eastern and Central Europe. This diffusion could be identified with the migration of first anatomically Modern Humans. The Early Upper Palaeolithic in Europe — dated to the second half of the Interpleniglacial — was, at least partially, based on these “transitional” industries and manifested by the appearance of the Aurignacian, contrasted with local cultures such as the Uluzzian in Mediterranean Europe. During whole the Interpleniglacial Europe was separated from Northern Africa dominated by local evolution of Middle Palaeolithic (Middle Stone Age) cultures (mostly expressed by the Aterian), and by specific “transitional” industries on the southern Mediterranean coast (Early Dabbian) and in the Lower Nile basin. The Last Glacial Maximum and the corresponding sea level recession opened new possibilities of contacts between the Maghreb and the Iberian Peninsula in both directions (Aterian-Solutrean and Gravettian-Early Iberomaurusian), which are still difficult to be proved before new chronostratigraphic correlations are made. At the same time we register links between south-eastern Europe and western Anatolia; the real border between Near Eastern and European Mediterranean cultural zones was marked, in the Late Glacial, by the Taurus chain. During the Late Glacial the cultural separation between Europe and Africa was particularly marked. Only in the Aegean basin the first sea navigation facilitated contacts which become widespread as late as in the Early Holocene with neolithization trough maritime contacts.     

Biostratigraphie des brachiopodes et âge carixien (Pliensbachien inférieur) des calcaires à grands bivalves en Algérie occidentale

Recent researches on the Lower Jurassic of Western Algeria allow to establish a lithostratigraphic standard correlating the different members and formations developed in the Ouarsenis and Tlemcen Mountains, the Oran High Plains, the Nador and Ksour Mountains. The position of the large bivalve limestones (= Lithiotis limestones) is well established in the different lithologic successions. This facies is widespread in Western Algeria where it is interbedded with brachiopod marker beds, indicating short periods of maximum flooding. The large number of collected brachiopods are distributed into four “faunas” (assemblages) ranging from the Late Sinemurian (= Lotharingian) to the Early Pliensbachian (= Carixian). These faunas have been dated by the age of the species that they have in common with the NW european and western tethyan provinces. These chronological data are confirmed by rare ammonites. All these results evidence the age of the large bivalve facies in Western Algeria. They are contained in the Middle to Late Carixian (Demonense and Dilectum Zones). This datation is in conformity with that known from the Eastern High-Atlas (Bou Dahar). Consequently, the large bivalves cannot be considered as “markers for the unique Domerian” as it has been too often asserted. The palaeontological part of our study shows that the multicostate Zeilleriids (several Tauromenia species from the Late Sinemurian to the Early Carixian) are older than the multicostate Terebratulids (Hesperithyris species from the Middle to Late Carixian).     

A human mandible (BH-1) from the Pleistocene deposits of Mala Balanica cave (Sićevo Gorge, Niš, Serbia)

Neandertals and their immediate predecessors are commonly considered to be the only humans inhabiting Europe in the Middle and early Late Pleistocene. Most Middle Pleistocene western European specimens show evidence of a developing Neandertal morphology, supporting the notion that these traits evolved at the extreme West of the continent due, at least partially, to the isolation produced by glacial events. The recent discovery of a mandible, BH-1, from Mala Balanica (Serbia), with primitive character states comparable with Early Pleistocene mandibular specimens, is associated with a minimum radiometric date of 113 + 72 − 43 ka. Given the fragmented nature of the hemi-mandible and the fact that primitive character states preclude assignment to a species, the taxonomic status of the specimen is best described as an archaic Homo sp. The combination of primitive traits and a possible Late Pleistocene date suggests that a more primitive morphology, one that does not show Neandertal traits, could have persisted in the region. Different hominin morphologies could have survived and coexisted in the Balkans, the “hotspot of biodiversity.” This first hominin specimen to come from a secure stratigraphic context in the Central Balkans indicates a potentially important role for the region in understanding human evolution in Europe that will only be resolved with more concentrated research efforts in the area.     

Throwing in the Middle and Upper Paleolithic: inferences from an analysis of humeral retroversion

When in evolutionary history did long-range projectile weapons become an important component of hunting toolkits? The archeological evidence for the development of projectile weaponry is complex and generally indirect, and has led to different conclusions about the origin and spread of this technology. Lithic evidence from the Middle Stone Age (MSA) has led some researchers to suggest that true long- range projectile weaponry developed in Africa perhaps as early as 80,000 years ago, and was part of the subsistence toolkit carried by modern humans who expanded out of Africa after 50,000 years ago. Alternatively, temporal patterns in the morphology of pointed lithics has led others to posit an independent, convergent origin of projectile weaponry in Africa, the Near East, and Europe during the interval between 50,000-40,000 years ago. By either scenario, projectile weapons would not have been a component of the hunting arsenal of Neandertals, but may have been in use by European early modern humans and thus, projectile technology may have entered into the competitive dynamics that existed between these two groups. The origins of projectile weapons can be addressed, in part, through analyses of the skeletal remains of the prehistoric humans who made and used them. Habitual behavior patterns—including those related to the production and use of technology—can be imprinted on the skeleton through both genetic and epigenetic pathways. Recent studies in the field of sports medicine indicate that individuals who engage in habitual throwing have increased humeral retroversion angles in their throwing arms and a greater degree of bilateral asymmetry in retroversion angles than do non-throwers. This contribution investigates humeral torsion through analysis of the retroversion angle in samples of Eurasian Neandertals, European early modern humans of the middle and late Upper Paleolithic, and comparative samples of recent humans. This analysis was conducted under the assumption that if throwing-based projectile weaponry was used by early modern Europeans but not Neandertals, Upper Paleolithic samples should be similar to recent human groups engaged in habitual throwing in the degree of humeral retroversion in the dominant limb and in bilateral asymmetry in this feature. Neandertals on the other hand, would not be expected to show marked asymmetry in humeral retroversion. Consistent with other studies, Neandertals exhibit increased retroversion angles (decreased humeral torsion or a more posteriorly oriented humeral head) relative to most modern human samples, although this appears more likely related to body form and overall activity levels than to habitual throwing. Although Neandertals with bilaterally preserved humeri sufficient for measurement are rare (consisting of only two males and one female), levels of bilateral asymmetry in humeral retroversion are low, suggesting a lack of regular throwing. While patterning across fossil and comparative samples in levels of humeral retroversion was not clear cut, males of both the middle and late Upper Paleolithic demonstrate a high level of bilateral asymmetry, comparable to or in excess of that seen in samples of throwing athletes. This may indicate habitual use of throwing-based projectile weaponry by middle Upper Paleolithic times. Small sample sizes and relatively great variance in the fossil samples makes these results, however, suggestive rather than conclusive.     

Phylogeography of the heavily poached African common pangolin (Pholidota,Manis tricuspis) reveals six cryptic lineages as traceable signatures of Pleistocene diversification

Knowledge on faunal diversification in African rainforests remains scarce. We used phylogeography to assess (i) the role of Pleistocene climatic oscillations in the diversification of the African common pangolin (Manis tricuspis) and (ii) the utility of our multilocus approach for taxonomic delineation and trade tracing of this heavily poached species. We sequenced 101 individuals for two mitochondrial DNA (mtDNA), two nuclear DNA and one Y‐borne gene fragments (totalizing 2602 bp). We used a time‐calibrated, Bayesian inference phylogenetic framework and conducted character‐based, genetic and phylogenetic delineation of species hypotheses within African common pangolins. We identified six geographic lineages partitioned into western Africa, Ghana, the Dahomey Gap, western central Africa, Gabon and central Africa, all diverging during the Middle to Late Pleistocene. MtDNA (cytochrome b + control region) was the sole locus to provide diagnostic characters for each of the six lineages. Tree‐based Bayesian delimitation methods using single‐ and multilocus approaches gave high support for ‘species’ level recognition of the six African common pangolin lineages. Although the diversification of African common pangolins occurred during Pleistocene cyclical glaciations, causative correlation with traditional rainforest refugia and riverine barriers in Africa was not straightforward. We conclude on the existence of six cryptic lineages within African common pangolins, which might be of major relevance for future conservation strategies. The high discriminative power of the mtDNA markers used in this study should allow an efficient molecular tracing of the regional origin of African common pangolin seizures.     

L’Aurignacien archaïque de la grotte El Castillo (Espagne) : caractérisation technologique et typologique

In this paper, we present the techno-typological study of level 16 of El Castillo cave (Archaic Aurignacian). In this level, we can identify an important bladelet production from schémas opératoires of unipolar prismatic cores, carinated endscraper and carinated burins types. Besides, we find a specific production of Discoid conception. The retouched blanks, though scanty, are dominated by the Dufour bladelets. Level 16 is in relation with the Archaic Aurignacian at the Cantabrian Iberia, which is present in sites like Cueva Morín, Labeko Koba, Gatzarria, or Isturitz and it also is in relation with the Mediterranean Archaic Aurignacian. Finally, we analyse the different hypotheses about the Initial Upper Paleolithic origin in Europe. The mosaic hypothesis is acceptable for us.     

L'Azilien ancien de Cueva Oscura de Ania (Las Regueras, Asturias, Espagne)

Recent definition of the Cantabrian Lower Azilian has turned the Late Upper Magdalenian/Azilian transition into one of the most interesting archaeological ages in the area. This period is considered representing the earliest Azilian groups in Asturias. Critic review of Cueva Oscura de Ania record, in the center of Asturias, has allowed us to give full details of the Lower Azilian archaeological characteristics. Cueva Oscura de Ania archaeological collection shows archaic traits, close to those from Cueva de Los Azules and Cueva de La Riera, two eastern asturian sites. These likenesses suggest a high stylistic and technical uniformity in distant areas during a critical period, when Palaeolithic groups changed their subsistence strategies. Cueva Oscura de Ania archaeological and polinic records suggest that this deposit was built at the beginning of the paleoclimatic phase known as Alleröd/Cantabrian VIII (12 000-10?800 BP), when numerous cantabrian sites suffered high erosion processes. All these circumstances convert Cueva Oscura de Ania in a fundamental site to get a best knowledge of the origin and development of the Cantabrian Azilian. The study of its bone collection allows us outline new hypothesis about this archaeological period.     

Datations SMA et nouveaux regards sur l’archéo-séquence du Rond-du-Barry (Polignac,Haute-Loire)

A series of 36 radiocarbon AMS ages produced from separate bone fragments has prompted a new appraisal of the archaeological sequence of the Rond-du-Barry Cave (Polignac, Haute-Loire). A huge rock-fall of unknown age underlies Unit H, which contains evidence of the oldest human occupation of the site consisting of a Middle Palaeolithic assemblage dated to between 40 and 33 kyr. The first Upper Palaeolithic occupation of the Cave occurred later. In Unit F, three Badegoulian occupation sectors can be identified that are dated to between 20 and 17.5 kyr. The uppermost units, E and D yielded Middle and Upper Magdalenian dates of between 15.4 and 12.4 kyr. Within Unit E, a tephra related layer (E6) is likely to belong to a distal southern lobe of an eruptive event that was centred in the Chaîne des Puys, 100 km to the north. Unit D shows evidence of being re-worked at least during Mesolithic/Neolithic times, circa 6.5/4.9 kyr. The sum of this new evidence demonstrates the existence of a previously unrecognised stratigraphic and spatial complexity within the Rond-du-Barry archaeological deposits, which demands that new investigations be made in this cave.     

U–Pb SHRIMP age for the Tuchengzi Formation,northern China,and its implications for biotic evolution during the Jurassic–Cretaceous transition

The Late Jurassic–Early Cretaceous Tuchengzi Formation is widespread in North China. Its clastic deposits indicate a tropical, dry, and hot paleoclimate, different from the subtropical, humid, and seasonal climate in the early Middle Jurassic. The sudden environmental change from the Middle to Late Jurassic resulted in a rapid disappearance of the Yanliao/Daohugou Biota, with more than 90% of the species of the Yanliao/Daohugou Biota dying out and replaced by the Early Cretaceous Jehol Biota. Eolian sandstones with large-scale cross-bedding occur within the uppermost part of the Tuchengzi Formation in North China. The sandstones are stratigraphically higher than the tuff previously dated as 139 Ma. We obtained two SHRIMP zircon U/Pb ages from the tuff beds. One sample was collected from the tuff in the basal Tuchengzi Formation in northern Hebei and the other from the tuff intercalated in the eolian cross-bedded sandstones in the uppermost Tuchengzi Formation in western Liaoning. Our results show that 154 Ma is the oldest age constraint for the Tuchengzi Formation and 137 Ma is the youngest age estimate of the formation, providing an age constraint for the transition from the Yanliao Biota to the Jehol Biota.     

Dietary variation and stress among prehistoric Jomon foragers from Japan

Current archaeological evidence indicates that greater dietary reliance on marine resources is recorded among the eastern Jomon, while plant dependence prevailed in western/inland Japan. The hypothesis that the dietary choices of the western/inland Jomon will be associated with greater systemic stress is tested by comparing carious tooth and enamel hypoplasia frequencies between the eastern and western/inland Jomon. Demographic collapse coincides with climate change during the Middle to Late Jomon period, suggesting dwindling resource availability. It is hypothesized that this change was associated with greater systemic stress and/or dietary change among the Middle to Late Jomon. This hypothesis is tested by comparing enamel hypoplasia and carious tooth frequencies between Middle to Late and Late to Final Jomon foragers. Enamel hypoplasia was significantly more prevalent among the western/inland Jomon. Such findings are consistent with archaeological studies that argue for greater plant consumption and stresses associated with seasonal resource depletion among the western/inland Jomon. Approximately equivalent enamel hypoplasia frequencies between Middle to Late and Late to Final Jomon foragers argues against a demographic collapse in association with diminished nutritional returns. Significant differences in carious tooth frequencies are, however, observed between Middle to Late and Late to Final Jomon foragers. These results suggest a subsistence shift during the Middle to Late Jomon period, perhaps in response to a changed climate. The overall patterns of stress documented by this study indicate wide-spread environmentally directed biological variation among the prehistoric Jomon.     

Le Magdalénien de la grotte « Grappin » à Arlay (Jura, France) : nouveaux regards

The “Grappin” or “Saint-Vincent's” cave, on the western slope of Jura, East of France, has been explored since 1889. From then to 1960, it has yielded substantial material dated to middle “à navettes” Magdalenian developing during the late Pleniglacial. The study of this settlement, although often mentioned, was never dealt with comprehensively until now. Due to its scientific importance for the middle Magdalenian of western Europe, the site is to be reinvestigated through a global interdisciplinary project entitled “The Tardiglacial and the start of Holocene in the Jura and its margins”. This paper will review our present knowledge of the site, radiocarbon dates and archaeological data. It also focuses on ornaments and engraved mobile art.     

Découverte des sites du Paléolithique inférieur au Nord de l’Arménie

For a long time, the scientific community assumed that the Acheulean culture was expressed on the territory of the Armenian Plateau as well as in the neighboring regions of the Caucasus only by its late phase; therefore, it appeared in the second half of the Middle Pleistocene. In recent years, the Armenian-Russian mission has discovered and studied much older Acheulean industries sites, located in northern Armenia (the Lori intermountain Depression). These industries, represented by archaic type tools (large hand axes, picks, choppers, chisel-like tools, scrapers, points, etc.), are discovered in three deposits of origin of proluvial genesis. In the Karakhach site, this type of industry is deposited in the lower levels of volcanic tuff and below; the U/Pb study of this level of tuff proposes a series of dates, assigned to the time interval between 1.944 + 0.046 and 1.75 + 0.02 Ma. The paleomagnetic study demonstrated the inverse polarity on the tuff and the normal polarity of the underlying deposits; in correlation with other dating, this fact allows to attribute the Acheulean layers of the site of Karakhatch to the Lower Pleistocene, in particular to the Oldoway episode and to the Upper Matuyama time period. The estimated age and the techno-morphological characteristics of the tools indicate the Lower Acheulean period. The dating of the Muradovo site does not seem possible, however its very old industries and the archaeological layers, where they were discovered, find equivalents in the layered layer, surmounted by tuffs, of the Karakhatch site. The Kutran I site presented a paleosol sequence with similar Acheulean tools (hand axes, picks, choppers, etc.). Its oldest layer is older than 1.5 Ma, the upper layer is attributed to the early Middle Pleistocene; this fact means that it is possible to speak of the Lower Acheulean and of its transition to the Middle Acheulean period. The specific character and the age of the Lower Acheulean of Armenia admit that it could have formed independently of the Lower Acheulean of Africa, whose estimated age does not rise before 1.76 Ma. It should also be noted that on the neighboring territory of Georgia about the same time when appeared the Acheulean culture in Armenia, the Oldowan Dmanisi site already existed.     

Earliest occurrence of Puma pardoides (Owen, 1846) (Carnivora,Felidae) at the Plio/Pleistocene transition in western Europe: New evidence from the Middle Villafranchian assemblage of Montopoli,Italy

The puma-like cat Puma pardoides (Owen, 1846) is reported from several Eurasian localities dated to the Late Pliocene–Early Pleistocene, but its Italian fossil record is really poor; in fact, the only possible occurrence comprises some fragmentary postcranial material from the Late Villafranchian locality of Pirro Nord (1.6–1.3 Ma). In the present paper, we describe an isolated left upper carnassial of a medium-sized felid belonging to the collection of fossil mammals from Montopoli (Tuscany, Italy), the type locality of the Middle Villafranchian Faunal Unit (∼2.6 Ma). All the morphological and morphometric characters of the tooth are consistent with an attribution to Puma pardoides (Owen, 1846), which comes out as the second felid species from Montopoli together with Acinonyx pardinensis (Croizet et Jobert, 1828) and is, possibly with the specimens from Perrier-Étouaries, the earliest occurrence in western Europe.     

Hominin Dispersal into the Nefud Desert and Middle Palaeolithic Settlement along the Jubbah Palaeolake,Northern Arabia

The Arabian Peninsula is a key region for understanding hominin dispersals and the effect of climate change on prehistoric demography, although little information on these topics is presently available owing to the poor preservation of archaeological sites in this desert environment. Here, we describe the discovery of three stratified and buried archaeological sites in the Nefud Desert, which includes the oldest dated occupation for the region. The stone tool assemblages are identified as a Middle Palaeolithic industry that includes Levallois manufacturing methods and the production of tools on flakes. Hominin occupations correspond with humid periods, particularly Marine Isotope Stages 7 and 5 of the Late Pleistocene. The Middle Palaeolithic occupations were situated along the Jubbah palaeolake-shores, in a grassland setting with some trees. Populations procured different raw materials across the lake region to manufacture stone tools, using the implements to process plants and animals. To reach the Jubbah palaeolake, Middle Palaeolithic populations travelled into the ameliorated Nefud Desert interior, possibly gaining access from multiple directions, either using routes from the north and west (the Levant and the Sinai), the north (the Mesopotamian plains and the Euphrates basin), or the east (the Persian Gulf). The Jubbah stone tool assemblages have their own suite of technological characters, but have types reminiscent of both African Middle Stone Age and Levantine Middle Palaeolithic industries. Comparative inter-regional analysis of core technology indicates morphological similarities with the Levantine Tabun C assemblage, associated with human fossils controversially identified as either Neanderthals or Homo sapiens.
