Gravures et abstraction: Les gravures non figuratives de Roc-la-Tour I, le schiste gravé des Beaux-Sarts et les progrès de l’abstraction durant la Préhistoire et l’Histoire

Beyond the 75 animal and human pictures, the 491 Magdalenian engraved plaquettes bear 410 abstract signs, in 14 different types, among which eight were unknown up to now in South-Western France, (more than 130 cases). Some examples of all those signs are shown. Besides there are 213 groups of parallel lines. At “Les Beaux-Sarts”, less than 2 m from the hut described in 2003, another human excavation (maybe a tomb?) delivered a schist plaquette with 94 parallel lines carved on its surface, the lines appear as three groups of 14, 7 (or 8?) and 24 (or 28?) lines and one group of 17 (or 18?) oblique lines, with various secondary lines. Five thousand years before the cerebral center of precise calculation was at the beginning of its formation, this piece, out of the bases of which calculation might be subdivided, cannot be considered as the evidence that they were able to count. The author analyses the affective mental possibilities proved by those elements and puts them apart from the rational progress in the abstraction possibilities of the human brain, which occurred later all through ten thousand years.     

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.     

Figurations de l’amas stellaire des Pléiades sur deux roches gravées de la région du Mont Bego Z IX. GII. R 4 et Z IX. GIII. R 6

Two engraved rocks are situated 140 m from each other at an altitude of about 2250 m. One of them is called “female dancer”, and the other, “the Pleiads”, and both show a group of seven small pitted areas, of which one is smaller than the others and ‘ identified as the “Pleiads stellar cluster”, often depicted or mentioned during Antiquity and also throughout various historical periods.On each of these rocks, a large halberd, whose handle is oriented east-west, was traced along a natural fissure in the rock and engraved in the center of the composition. The “Pleiads stellar cluster” is represented on each of the two rocks beside the halberd : although situated to the west above the halberd blade on the “female dancer” rock, it is placed to the south and to the left of the halberd handle on “the Pleiads” rock. This difference may mark two distinct calendar data.The position of the different figures in the compositions illustrated on these two rocks, in particular inversions in the representation of some of them may indicate two distinct periods of the agricultural yearly cycle: on the rock called “female dancer”, the “heliacal raise” at summer's end, marking the beginning of the harvest and, on the rock called “the Pleiads”, the “heliacal setting”, just before winter, after the end of the harvest, when the rains soaks the ground and it is time to plow.     

La séquence anthracologique de la grotte du Parco (Alòs de Balaguer,Espagne) : paysages et gestion du combustible chez les derniers chasseurs-cueilleurs

The objective of this paper is to present the anthracological data of the Parco cave sequence. This cave, excavated since the last 25 years, shows a stratigraphic sequence from the Upper Palaeolithic to the Bronze age. The anthracological data that we are presenting correspond to the sequence corresponding to the Magdalenian and Epipaleolithic layers. The anthracological data show a dominance of Scots pine at the bottom and of junipers at the top of the deposit, suggesting a landscape transformation though time. From these results we discuss aspects related to the vegetal formations during this period. Moreover, this study has the intention of integration the anthracological record with the archaeological data already published concerning subsistence, technology and paleoecology to a better understanding to human behaviour during this period.     

Les associations des calpionelles du Berriasien et du Valanginien inférieur de la Tunisie septentrionale. Comparaison avec les associations du Rif externe (Maroc)

The study of ten thin sections from outcrops from Lower Cretaceous deposits and several thin sections obtained from three petroleum wells, allow us to better characterize the associations of calpionellid zones and subzones of the Berriasian and Lower Valanginian in northern Tunisia. The B and C zones, respectively, show three and two levels with calpionellid associations corresponding to B1, B2, B3 and C1, C2 subzones. In the D zone, associations of the D1 and D2 subzones were identified. The E zone has been characterized for the first time in Tunisia and in southern-Tethyan margin of North Africa, on the basis of its index specie and associated species.     

Une lame de faucille sous la stèle gravée Chalcolithique dite du « Chef de tribu », Vallée des Merveilles, région du Mont Bego, Tende, Alpes-Maritimes

The carved stele known as the “head of the tribe”, attributed to the Chalcolithic, erected at an altitude of 2290 m in the chaos of blocks in the Merveilles torrent in the Mont Bego region at Tende, was removed from its original standing place. Earth extracted from under the stele and sieved yielded a sickle blade in very fine and homogeneous Bedoulian pale biege translucid flint, pressure flaked on a heated core. The blade bears a light polish caused by cereal harvesting. This sickle blade is similar to those widely used in the southern Chassey culture (4300 to 3000 years before our era) but also sometimes in the Campaniform culture, during the ancient and middle Bronze age, like in Murée cave, in the Verdon gorges. The location of the sickle blade at the foot of the carved stele, known as the “head of the tribe”, is not just coincidental. It is highly probable that the blade was intentionally placed beside this rock. It is seemingly during a ritual ceremony that this sickle blade, probably still inserted in a wooden handle, was intentionally placed, in a propitious gesture or as an offering, beside the stele known as the “head of the tribe”.     

Les Megacricetodon du gisement karstique miocène moyen de Blanquatère 1 (Pyrénées-Orientales, Sud de la France) : nouvelles espèces, implications biochronologique et phylogénique

Three Megacricetodon species are recognized in the Middle Miocene locality of Blanquatère 1 (Languedoc-Roussillon province, France). Two are new, the small-sized M. tautavelensis nov. sp. the medium to large-sized M. aunayi nov. sp., the third one being the already known M. “collongensis-gersii”, a medium-sized species found in other Miocene localities of the area. Size and morphology differentiate these species. Such a high number of contemporaneous species of the genus Megacricetodon is found for the first time in a Miocene locality in the region and indicate that the evolution of this genus in western Europe is likely more complicated. It may testify both of a biogeographical differentiation and of migration events. According to our calibration charts, the deposit is dated ca. 16 Ma ago. The position of Vieux-Collonges (MN 5) and Sansan (MN 6) on the biochronological scale is also discussed, as well as the estimated age of the biozonal boundaries MN 3/MN 4, MN 4/MN 5 and MN 5/MN 6.     

Nouveautés sur la séquence du Pléistocène final et l’Holocène initial dans le versant méditerranéen de la péninsule Ibérique à travers l’industrie lithique

This paper explores the cultural sequence for the period 12,500–9000 BP in the Mediterranean coast of the Iberian Peninsula. According to the traditional division by Fortea, this period starts with the end of the Upper Magdalenian, followed by two facies: the Microlaminar Epipalaeolithic and the Geometric Epipalaeolithic (Filador type), (related to Sauveterrian facies). The data collected in recent years suggest a change or amendment to this previous proposal, which now would be divided into four phases: Final Upper Magdalenian, Early Epimagdalenian, Recent Epimagdalenian and Microlaminar Sauveterroid. This paper discusses each of these periods examining the evolution of the stone tools and concluding that in the Mediterranean coast of the Iberian Peninsula the Magdalenian tradition continues with little changes until the advent of the Mesolithic.
