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.     

La variabilité graphique du Molí del Salt (Vimbodí, Catalogne, Espagne) et l'art mobilier de la fin du Paléolithique supérieur à l'est de la Péninsule Ibérique

The Upper Paleolithic of Catalonia has been so far characterized by a very weak presence of artistic representations. This scarcity was especially surprising if we take into account the huge number of discoveries from other zones of the Iberian Peninsula (Valencia, the Cantabrian region). In this paper we present four objects of portable art found at the Molí del Salt site (Vimbodí, Conca de Barberà, Tarragona). Below a mesolithic layer, dated to 8 ka BP, there is an Upper Magdalenian sequence with several dates between 10.8 and 12.5 ka BP. These magdalenian levels have yielded four plaques of schist with engravings, including several animal figurines and one human representations. Once the objects are described, we will place them in the context of the portable art from the Late Upper Paleolithic of Mediterranean Spain. From these data, the chronocultural successions based on the Upper Magdalenian-Microlaminar Epipaleolithic distinction will be discussed.     

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.     

Les industries magdaléniennes de l’Ardèche (France) dans le contexte du bassin méditerranéen

Ardèche, a department of Rhone Alpes region, is rich in prehistoric sites belonging to a very large chronological period dated back to 350?000 years ago. But, the prehistory of the region has been unknown for a long time, mainly, because of its distance from traditional centres of research. Jean Combier, in his abstract dated 1967, defined for the first time Upper Palaelolithic stages: only towards the acquisition of new data, we are now able to suggest a new evolution for the Magdalenian from its origins to the Alleröd climatic episod. To define Ardèche originality within the Magdalenian context, we have compared its lithic industries with those of the Adaouste Cave oriental sites, the Cornille rock shelter and of the Gazel cave in the Aude western part. Ardèche Magdalenian dwelling is peculiar compared to the South West of France. Badegoulian has been substituted by a Mediterranean Facies culture rich in bladelets, the Salpestrian. This facies limited in its geographic extention to Gard and Ardèche, evolves gradually in situ gaining Magdalenian elements (such as backed bladelets and dihedral burins) giving birth to the transitory lithic complex of Huguenots and Baume d’Oullins Cave. An established Magdalenian is certified in the Blanchisserie camp, within a cold climatic context dated back to circa 16?000 years ago. Although the lithic industry is dominated by dihedral burins and backed bladeletse it is also characterised by some archaic features (such as keel endscrapers, transverse burins and scalene bladelets). The upper Magadalenian with bone harpoons appears soon in our region, in the Colombier rock shelter, in a fairly temperate climatic context dated according to 14C back to circa 14?000 BP. We could identify six stages within the evolution of this Upper Magdalenian.which are attested in the Colombier, Ebbou and Deux Avens Caves and in the Colombier rock shelter that has been occupied during several periods. The Magdalenian gradually changed loosing his most typical elements, the bladelets and burins supremacy has been substituted by Azilian elements (such as short endscrapers and curved backed points). But even if the Azilian process happens very early (before 12?500 BP) the Magdalenian, in its fundamental features, never disappears completely and it has never been substituted by classic Azilian. After Alleröd appears a culture characterised by the recovery of Magdalenian features similar to the Epimagdalenian defined by D. Sacchi in Gazel. The described evolution can be compared, as regard to its upper stages, to that of several sites of Rhone region as well as of the North West of France, which allow to define a culturally homogeneous province having the Rhone corridor with Ardèche as its Southern border. At the end of Palaeolithic this province broke up and Ardèche opened to the South and the Mediterranean from where seems to come the retouched large blade facies and endscrapers attested by the Colombier rock shelter dating back to 12?150 BP.     

Témoins du froid. La faune dans l’art rupestre paléolithique de l’intérieur péninsulaire

It is our intention to analyse the environmental significance of the Palaeolithic artistic representations existing in the inner areas of the Iberian Peninsula. The fauna is used to create chronological and climatical criteria to affirm the condition of the castillan plateau during the last glaciation. In our opinion, it is dangerous to use the isolated animals in order to talk about coldness or heat situation because they reflect the cultural selection of their authors more than the ambiental reality. Neither the animals called thermometer nor the euritherm ones are solely represented in the tempered moments. Moreover, we have almost a no animal representation than artistic during the last finiglacial period in the peninsular interior. It means probably that the artistic representations are mainly cultural signs, which change for cultural reasons and not properly climatic ones within a general reality of glacial environment.     

La Lloseta : une grotte importante et presque méconnue dans l'ensemble de Ardines, Ribadesella

This summary on The Lloseta shows us a much richer reality that it had been presented through the precedent publications. To begin it is presented as an shelter environment decorated in all their extension whose decoration and parallel they find real sense if we put them in connection with the neigh boring Tito Bustillo. It possesses a prevalence of signs and old representations, a bad general conservation and an own and original internal organization. None of the caves of Ardines, including their main protagonist, she makes isolated significant sense, but rather they are and were supplemented in the past, for activities, occupation and use. We try to know the meaning of all and each one of the caves in connection with the other ones, because we think that their function should be collective and complementary.     

Le paléolithique supérieur au sud du Portugal : le site de Vale Boi

Before the 90s, data on Paleolithic human occupation of southern Portugal was very scarce. During the last decade, the knowledge of the Upper Paleolithic of Algarve increased substantially due to the work of a research team based at the University of Algarve. The present paper is a report on the recent results from Algarve, focusing specially on the site of Vale Boi. It will present the chronology and stratigraphy of different human occupations from the early Upper Paleolithic up to the early Neolithic. It will focus on aspects of zooarchaeology and the exploitation of large and medium mammals as well as on marine fauna. In addition, we will present new data on stone and bone tools. Finally, we will also refer to the social and symbolic aspects present at the site, base on shell and teeth pendants and to an engraved plaquette with animal motifs.     

La chronologie du Néolithique ancien cardial du nord-est de la péninsule Ibérique. Datations, problématique et méthodologie

In this work, we make a compilation of all radiocarbonical data existing for the cardial Neolithic culture in the northwest of the Iberian Peninsula with the aim to delimit as much as possible the chronological range attributed for this period. For this reason calibration of all data is presented on the same curve, taking into account the critical process for all of them based on stratigraphical, taphonomical and radiometrical concepts. Finally, is shown that chronological range of cardial Neolithic culture could be focused on the 2nd half of the VI millennium cal. BC.     

Application d'une méthode d'analyse du territoire à partir de la situation des marqueurs graphiques à l'intérieur de la Péninsule Ibérique : le Tage International

This paper, analyses the graphic evidences of the boundaries of Tagus between Spain and Portugal from the perspective of the model defended by our team. This model proposes the existence of the relationship between graphic markers: paintings, engravings in the open air, decorations over dolmens and menhirs, understood as a compact ideological group fixed in the organization social system of European producing people and metallurgical that occupying this landscape. This argument attempt to verify the possibilities of applying a pre-defined model in an area in which have been developed investigation models, focused to study megalithic monuments, menhirs, habitational areas, paints and engravings that shows symbolic expressions of the tradition to justify the property of rich areas in natural resources in what metallurgical have a remarkable importance.     

Relations entre les représentations figuratives et les signes dans trois grottes magdaléniennes : Les Combarelles I, Rouffignac (Périgord, France) et Altxerri (Pays basque, Espagne)

Magdalenian signs are more numerous and more varied than ones of another periods in the Upper Palaeolithic. In the 3986 signs studied in 28 caves, 2364 signs, or 59,3% of signs are associated with figurative representations. For the question about the relations between the figurative representations and the signs associated, we chose four parameters: thematic analysis, interior analysis, chronological analysis and external analysis. Especially in three caves like Les Combarelles I, Rouffignac (Périgord, France) and Altxerri (Spanish Basque), we got interesting results by those analyses. The thematic analysis let find whether the themes are associated with specific signs. In the many caves, the most numerous figurative representations are often associated with signs. About the interior analysis, many signs are located on the flank of the animal figures. And, the chronological analysis show that the signs were made before the figurative representations the same times that after. The anteriority of making signs and the posterity depends on the place (external analysis) in the three caves. So, our analysis methods with those varied parameters make the signs characterized by type, by cave or by region.     

Sols et structures d’habitat du Paléolithique supérieur, nouvelles données depuis les Cantabres : la Galerie Inférieure de La Garma (Cantabrie, Espagne)

A brief review is done of the history of the research on Upper Paleolithic floors and structures, with a general outline of the main substantive and theoretical-methodological aspects. On the resulting “state of the art” we present the preliminary results of the study of the occupation evidences from the Lower Gallery of La Garma. In essence, it constitutes an astonishing ensemble of extensive Middle Magdalenian occupation floors, exceptionally rich and quite well preserved, including several structures and associated with rock art paintings and carvings of that period. The potential of the site is superlative, and the research’s project already begins to offer some interesting results of which this article is a fairly small advance.     

Le concept de sigmassociation et son application a l'etude du paysage vegetal des falaises atlantiques françaises

Résumé Le concept de sigmassociation (sensu Tüxen 1973–1976) est discuté dans une première partie. Il dérive de la notion des complexes de groupements, progressivement développée par Braun-Blanquet dans les éditions successives de sa Pflanzensoziologie (1928, 1951, 1964). Le Tableau 1 résume les différences essentielles entre sigmassociation et complexe de groupements.Dans la deuxième partie de l'exposé, des examples de sigmassociations sont étudiés sur les côtes atlantiques françaises: ceux, notamment, des falaises cristallines armoricaines et des falaises crétaciques normandes. Le tableau 2 explicite bien les variations dans la combinaison des groupements pour chaque cas. A une combinaison différente des groupements constitutifs des sigmassociations correspond une physionomic totalement autre du paysage. Quelques problèmes concernant les sigmasystèmes sont présentés en conclusion.Parce que le concept de sigmassociation paraît spécialement fructueux pour le développement d'une science chère et tout particulièrement utile dans l'approche scientifique des problèmes de l'environnement végétal, j'ose dédier, très amicalement et à l'occasion de son 60ème anniversaire, cette modeste note, au Professeur V. Westhoff, éminent spécialiste de la végétation néerlandaise et inlassable protecteur de la Nature.

Chronologie de l’art Mégalithique ibérique : C et contextes archéologiques

From the beginning of our investigation we found the necessity of locating the Megalithic Iberian art in the chronology that came off of the well-known data in the peninsula at the end of the 1980s and of those that manifested the Atlantic long sequences. Then, we argue the dates obtained in the deposits of decorated dolmens to endorse the chronological similarity between architectures and decorations. To it, we could add decorations in the nonvisible area of some slabs that they even aimed a bigger antiquity. With that material, we organize our first chronological proposal for the Megalithic Iberian art, in which we assumed dates of fifth millennium lime BC for the oldest decorations, in consonance with the construction of the first megaliths. Moreover, it would be right so much in the supposedly classic areas as in the less favoured sectors for the investigation: the Interior, the South and the West of the Iberian peninsula. In successive works we are configuring a hypothesis on its development and chronology that offers more and more confirmations. The documentation of AMS dates on megalithic paintings, a unique case in the megalithic European art, comes to consolidate the chronology of the megalithic Iberian art. With all the data obtained in the last twenty years, we are arrived to the moment for establishing a sequence to adjust their times, to value complex situations in the decoration of the monuments and to confirm a long chronology that arrives practically as a residual way to Iron Age.     

Structures de végétation et conservation des zones humides temporaires méditerranéennes : la région des Mogods (Tunisie septentrionale)

Floristic surveys and phytoecological relevés were conducted on 36 temporary wetlands of Mogods region. Multivariate analyses (CA, AHC) performed on these data reveal the high specific and biocoenotic diversity of Mogods wetlands, which appear controlled by substrate nature and hydrology. Among the 128 hydrophytic species inventoried, 38 are presently in precarious status and 6 are presumed extinct. The Mogods region harbours, moreover, very rare habitats (peatlands and semi-permanent lakes), and a vast plain so-called Garâa Sejenane, exceptionally rich in temporary wetlands. These results underline the urgency of an adapted conservatory management, based on the development of scientific studies dealing with structure and functioning of hydrophytic communities of the region.     

Prospections sur les plateaux désertiques du désert libyque égyptien (Abydos, Moyenne Égypte). Quelques exemples de technologies lithiques

Recent work in the high desert west of the historic site of Abydos has revealed a number of technologies that date from the Middle Paleolithic through later periods. The earliest of these include both Nubian and classical Levallois technologies, which are abundant and demonstrate virtually all stages of production. Presumed later technologies include both large blade production technologies as well as more expedient reduction methods. Although results are still preliminary, the lack of significant taphonomic disturbance, the abundance of refits (including many discrete flintknapping episodes), and the high visibility of the archaeological remains make this an ideal area to reconstruct the techniques of lithic reduction in use.     

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.     

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.     

Le travail des matières d’origine dure animale dans le Magdalénien Morave : l’exemple des aiguilles à chas

Needles made from hard animal tissues are a stereotyped artefact; they have been found in six caves of the Moravian Karst / Czech Republic (Pekárna, ?itného, K?lna, Bý?í skála, Verun?ina, K?í?ova) containing Magdalenian layers. The paper deals with the technology of the production of these objects on the example of the Pekárna cave that has provided a lot of these artefacts in various degrees of wear, fragments, exploitation matrices and uncompleted needles. By the mean of spatial analysis we try to reconstitute the original context in the cave and insert the concerned artefact into the frame of the exploitation, treatment and utilisation of hard animal tissues by Magdalenian hunters in Moravia.     

Évolution des caractères technologiques et typologiques des industries lithiques dans la stratigraphie de la Caune de l'Arago

The thick Quaternary deposits of the Caune de l’Arago (Pyrénées-Orientales, France) are dated to between 690 000 and 90 000 years old. At least fifteen different archeostratigraphical units have been identified within these deposits, each corresponding to distinct prehistoric occupations. Numerous stone tools made from several different rock types, have been discovered in each unit. The tools present specific characteristics concerning the choice of raw materials, the typology, and the technology used to produce them. Morpho-technological study of the different components of the assemblage contributes to a better understanding of the debitage methods used for their production. Each raw material is considered individually in order to ascertain its origin in the environment, its typological role and the technology applied during its exploitation. Defining production systems leads to the characterisation of the assemblages from each unit. When compared, they reveal common elements, as well as differences, suggesting evolutionary trends. Some observations are also made concerning the extent to which changing uses of the site may have influenced the general morphology of each assemblage, therefore taking into account exterior factors. Analysis of this rich stone tool assemblage helps to situate the Caune de l’Arago industry within the larger evolutionary context of the Lower Paleolithic in Mediterranean Europe.     

Facteurs responsables de la distribution des gastéropodes dulcicoles dans le fleuve Saint-Laurent

A study of the freshwater gastropods in the Saint Lawrence river near Montreal was undertaken to characterize the populations living in the benthos and on the vegetation, and to define the effects of a deterioration of water quality.Ninety-eight samples, collected simultaneously from the benthos and on macrophytes, were expressed as the logarithm of each species' relative abundance. WPGMA clustering, principal coordinates and discriminant analysis were used to describe and characterize differences between samples. Diversity was also computed to show the transformations of population structure due to differences in pollution levels.Prosobranch snails predominated in benthic populations while pulmonates characterized vegetation. A decrease in the number of species was the characteristic response to increasing pollution levels upon both types of substrates. High hydrocarbon levels were related to a decrease in the diversity of snail populations on the vegetation only.Predominance of prosobranchs in the benthos and pulmonates on the vegetation could be explained by a differential dependence of those two groups of snails on the aquatic medium, and by considering modes of nutrition. Sporadic oil spills affected the snail populations living on macrophytes.
