Technological persistency following faunal stability during the Pleistocene: A model for reconstructing Paleolithic adaptation strategies based on mosaic evolution

Prehistoric archaeology focuses on innovations, transformations, and turnovers. We focus instead on persistency, suggesting that technological persistency in prehistoric hunter-gatherers was triggered by the stability of prey. The technological persistency-faunal stability nexus was not only crucial to human prosperity but also provided safe ground for technological and behavioral innovations, facilitating further adaptation to changing conditions. This can be viewed in the framework of mosaic evolution. We present six cases of morphological stasis enabling trophic adaptations and five archaeological cases of technological persistency following faunal stability. This model could contribute to a better understanding of technological persistency and its evolutionary role.     

The paleobiology of two adult skeletons from Baousso da Torre (Bausu da Ture) (Liguria,Italy): Implications for Gravettian lifestyle

This article presents the main skeletal characteristics of the two largely unpublished Gravettian adult skeletons from Baousso da Torre (Liguria, Italy). BT1 and BT2 were two adult tall males, who died aged respectively between 20 and 50 years, and between 20 and 30 years. Their body proportions fall within the range of variation known for the middle Upper Paleolithic, and their skeletal remains are characterized by considerable osteometric values, which fall consistently in the upper part of the Upper Paleolithic male sample variation. They show a high degree of upper limb lateralization, implying that they were likely involved in strenuous and/or repetitive unimanual tasks. They also exhibit very robust lower limbs, likely related to repeated long-distance travels in mountainous terrains. These results are in total agreement with previous hypotheses on Late Pleistocene population behavioral patterns.     

Analyse du débitage laminaire du site de Mezhyrich : habitations n 1, 2 et 3

This article presents the results of technological analyses of the laminar products from three bone dwelling structures from the Mezhyrich site (dated to Upper Palaeolithic; 15,000–14,500 years BP). More than 2500 blades and bladelets were studied from technological point of view. We find close similarity between the three dwellings, which reflects similar ways of preparation of core fracture zone (overhang reduction, butt abrading, and flaking surface isolation), as well as in the organization of the negative of the dorsal surfaces of the blades. The comparison with materials from the Kostenki 1 layer 1 site (upper layer, 22,000–24,000 years BP) shows some differences with the artefacts from Mezhyrich site, despite same technological methods. This could be explained by differences in cultural tradition and large time gap between these two sites. The complexes from Mezhyrich to follow the Kostenki 1/1 tradition but with their own particularities.     

Fish remains from the Neolithic site of El Mirador cave (Atapuerca,Spain): Seasonality and resource management

Ichthyoarchaeological analyses of the freshwater fish remains from levels 19 and 20 in El Mirador cave (Atapuerca, Spain) have been conducted. Fish were always present as a source of animal protein, although their importance in the human diet was not fully exploited by people during the Neolithic on the Iberian Peninsula. Two principal goals are treated here: a taxonomic study of the fish remains and a characterization of the exploitation of this resource. The results show that the human community of El Mirador cave practiced fishing, and that fish was part of their diet and social life.     

Test excavations and initial results at the Middle and Upper Paleolithic sites of Gilvaran,Kaldar, Ghamari caves and Gar Arjene Rockshelter,Khorramabad Valley,western Iran

This paper introduces the excavations in several Paleolithic sites in the Khorramabad Valley, Western Iran. Apart from the two well-known sites of Ghamari Cave and Gar Arjene rock shelter, first excavated by Frank Hole and Kent Flannery in the 1960s, the Gilvaran and Kaldar caves were excavated for the first time. Here we present the stratigraphy of these sites, general data from the lithic assemblages, and the identifications of a small part of the faunal remains. Preliminary results are showing that all of the sites were occupied from the Middle and Upper Paleolithic onward, and therefore provide great potential for the study of the transition between these cultural periods. Our preliminary techno-typological observations show that the lower levels of the Gilvaran and Ghamari sequences may represent an early phase of the Middle Paleolithic.     

Leporids as a potential resource for predators (hominins,mammalian carnivores,raptors): An example of mixed contribution from level III of Teixoneres Cave (MIS 3, Barcelona,Spain)

Apart from humans, other predators can take part in creating bone accumulations by generating waste materials that may have been mixed with those produced by hominids and leading to the formation of palimpsests. This is discussed here in the case of Middle Paleolithic leporid assemblages, to which carnivores have frequently contributed. Level III of Teixoneres Cave (MIS 3) is a sample that can be used to address the origin of leporid assemblages in archaeological contexts. Applying an archaeozoological and taphonomical methodology has made it possible to state that the assemblage of leporids in the site has been generated by a mix of contributions, in which small mammal carnivores and nocturnal raptors seem to play an important role, together with occasional hominid inputs. The aim of this paper is to present new data about Neanderthal activities at this site and support the hypothesis related to short-term human occupations in the cave.     

Blades,bladelets and flakes: A case of variability in tool design at the dawn of the Middle–Upper Palaeolithic transition in Italy

Neanderthals left diverse sets of cultural evidence just before the Middle–Upper Palaeolithic transition in Europe. Within this evidence, the production of lithic implements plays a key role in detecting possible affiliations (or lack thereof) with the techno-complexes that occurred during the few millennia before the large-scale spread of the Proto-Aurignacian. This crucial phase has also been recorded in the North of Italy, where around 44–45 ky cal BP, the last Neanderthals were still using the Levallois knapping technique, in common with the technology adopted at several sites in the central Mediterranean region. A similar picture is seen at the Grotta di Fumane, which provides the evidence presented in this paper. The production technology employed produced different levels of variability with respect to the production of blades, sometimes pointed, and the use of recurrent centripetal flaking at the end of the reduction sequence, in addition to bladelet and Discoidal volumetric structures. This variability does not outweigh the dominant tendency towards the use of elongated Levallois blanks and other by-products for shaping into basic retouched tools such as simple or convergent scrapers and points. A break from this apparently well-rooted use of the unipolar Levallois method is recorded in the Uluzzian where, instead, flakes and cores were made using the centripetal modality.     

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.     

L'expression schématique en Aragon présentation et recherches récentes

The shelters of the Aragon containing paintings are gathered together in two areas: one around the río Martin valley to the north of Teruel and one in the Sierra de Guara at the east of Huesca. In every case they coexist with sites containing Levantine paintings but the proportions between the two types of expression are variable. We suppose that this association or even competition, of these two different iconographies is related to the differences of Neolithic economies establishment in each region. Punctual excavations underside the schematic figures give for them different dating throughout the Neolithic period. It seems probant that shelters with schematic paintings were chosen among a multitude of potential sites following four particular conditions: their dominant position, their southern orientation, the orange colour of the cliff walls and the humidity of the place. Lastly, the detailed study of the ornated sites at the confluence of the Vero and the Choca valley reveals the existence of the groups of richly shelters and, on the over hand, the existence of isolated ones with a most soker decoration. Or, a good knowledge of the field shows that the first ones cannot be accessible if we do not pass by the second ones. Consequently, we propose the existence of a precise approaching paths allowing precise the arrival to the groups of richly decorated sites. The studied area would thus represent a structured sanctuary served by an access way that was marked out deliberately.     

Mégalithes et sociétés préhistoriques : concepts et terminologie

The restitution of the megalith’s technical manufacture, whith their assemblies lines and their sequences, enlarges the coast of the sens incluse in each Corsican monoliths. From the megalithics sites of Poghjaredda of Monte Rotondu (Sotta), Ciutulaghja (Appietu), and Presa (Altaghjè), some specifics activities area (pastoralism for example) or activities structured in the space (villages and tombs of middle Neolithic) interest this study. The contributions of many sciences permit to give an economic and social dimension to the choice of megalithics sites. Then, those choices are an aspect of the Neolithic process in Corsica, making part of sculpture and architecture. This study is conclued by a consideration on the actual worked stones’ terminology.
