Las representaciones artísticas de la Edad del Hierro identificadas en el Parque Arqueológico del Vale do Côa (PAVC) carecen de contextos de ocupación asociados, es decir, de los contextos estratigráficos necesarios para un marco cronológico e interpretativo. Ante la ausencia de evidencias de hábitat protohistórico en el entorno inmediato de los grabados, se buscó analizar otros yacimientos de la región en los que hubiera indicios de ocupación de la Edad del Hierro. Así, en el ámbito del proyecto RARAA - Repositorio Abierto de Arte Rupestre, financiado por el FCT COA/OVD/0097/2019, seleccionamos el yacimiento del Alto das Malhadas para realizar una intervención diagnóstica, debido a su relativa proximidad a la desembocadura del río Côa, asociada a la presencia de paneles rocosos con grabados, un guijarro con grabados incisos «protohistóricos» y materiales cerámicos artesanales. En este trabajo presentamos los resultados de esta intervención arqueológica, en la que el yacimiento del Alto das Malhadas, se ha revelado como uno de los más interesantes del nordeste de Portugal para la caracterización de la transición entre el III y el II milenio a. C. y para la comprensión de las claves de transición del Calcolítico regional a una Edad del Bronce cada vez más vinculada a la dinámica de asentamiento desarrollada en la Meseta., The Iron Age artistic representa tions identified in the Vale do Côa Archaeo logical Park (PAVC) lack associated occu pation contexts, that is, the stratigraphic contexts necessary for a chronological and interpretative framework. In the absence of evidence of protohistoric habitat in the immediate surroundings of the engravings, we attempted to analyse other sites in the region on which there was evidence of Iron Age occupation. Thus, as part of the RA RAA - Open Repository of Rock Art pro ject, funded by FCT COA/OVD/0097/2019, we selected the Alto das Malhadas site to carry out a diagnostic intervention, due to its relative proximity to the mouth of the Côa River, associated with the presence of rock panels with engravings, a pebble with «protohistoric» incised engravings and handmade ceramic materials. In this paper we present the results of this archaeological intervention, where the Alto das Malhadas site has revealed itself as one of the most interesting sites in north-eas tern Portugal for the characterization of the transition between the III and II millennium BC, and for the understanding of the transi tion keys from the regional Chalcolithic to a Bronze Age, increasingly linked to the sett lement dynamics developed in the Meseta.

The geomorphological context of the Côa Valley open-air Palaeolithic rock art offers a unique opportunity to analyse its stratigraphic relationship with preserved Quaternary deposits and to reconstruct those that may have since disappeared. Litho-stratigraphic units, discontinuities and their architecture are interpreted in the context of the valley’s evolution and its environment. The spatial distribution of rock art panels, chronological attribution of the rock art and their geomorphological context can help us to reconstruct the topography of the valley at the time of its production and to identify where rock art panels could be buried, as well as to establish their chronology.

Em 1999, um ano depois da classificação da arte paleolítica do Côa como património mundial pela UNESCO, uma sondagem em frente à rocha 1 do sítio do Fariseu revelou uma sequência de depósitos com vestígios do Paleolítico Superior sobre um painel gravado. Esta conjugação excecional de fatores humanos e naturais no registo arqueológico voltou a identificar-se em 2020, durante a realização de sondagens no mesmo sítio, uma centena de metros a montante. As observações efetuadas durante os trabalhos de campo, o estudo preliminar dos vestígios líticos e os dados adquiridos desde 1999 permitem precisar o contexto geomorfológico e a cronologia de realização das gravuras paleolíticas do Vale do Côa. Confirmam também a importância da arte ao ar livre como uma forma monumental de manifestação simbólica desde os momentos mais antigos do Paleolítico Superior., In 1999, a year after the classification of the Palaeolithic Art of the Côa as world heritage by UNESCO, a survey opposite rock 1 of the Fariseu site revealed a sequence of deposits with Upper Palaeolithic remains on an engraved panel. This unusual combination of human and natural factors in archaeological register was again identified in 2020, during surveys in the same site, about a hundred metres upstream. The observations during field work, the preliminary study of the lithic remains and the data obtained since 1999 have enabled the authors to determine more precisely the geomorphological context and chronology of the Palaeolithic engravings of the Côa Valley. They also confirm the importance of open-air art as a monumental form of symbolic expression since the earliest stages of the Upper Palaeolithic., En 1999, un an après la classification de l’art paléolithique du Côa comme patrimoine mondial par l’UNESCO, un sondage face à la roche 1 du site du Fariseu a révélé une suite de dépôts avec des vestiges du Paléolithique supérieur sur un panneau gravé. Cette conjugaison exceptionnelle de facteurs humains et naturels dans le registre archéologique s’est répétée en 2020 lors de la réalisation de sondages sur le même site, une centaine de mètres en amont. Les observations effectuées pendant le travail de terrain, l’étude préliminaire des vestiges lithiques et les données acquises depuis 1999 permettent de préciser le contexte géomorphologique et la chronologie de la réalisation des gravures paléolithiques de la Vallée du Côa. Elles confirment également l’importance de l’art à l’air libre comme une forme monumentale de manifestation symbolique depuis les temps les plus anciens du Paléolithique supérieur.

Neste trabalho apresenta-se o estudo integral da arte móvel identificada no Fariseu (Vale do Côa). Trata-se de um conjunto de oitenta e cinco peças gravadas e quatro pintadas. Dada a proveniência estratigráfica segura da coleção, a adscrição da maior parte das peças ao Dryas recente/ inícios do Pré-boreal está perfeitamente assegurada. As caraterísticas técnicas e estilísticas dos grafismos nela presentes são comparáveis a alguma da arte rupestre do Vale do Côa, o que faz da série do Fariseu um importante referente para a datação de um vasto número de painéis gravados e pintados desta região. Essas caraterísticas são igualmente semelhantes às de grafismos de diversas estações do Sudoeste europeu, datados dos finais do Tardiglaciar, o que denota a filiação deste fácies rupestre numa tradição gráfica de âmbito geográfico mais vasto., We present in this work the integral study of the portable art of Fariseu (Côa Valley). Eighty-five engraved pieces and four painted ones form the studied collection. The chronological attribution to the Late Dryas/ beginning of the Pre-boreal is perfectly assured by the stratigraphic origin of the pieces. The technical and stylistic attributes of the figures are similar to some of the rock art of the Côa valley, making the collection an important chronological referent to a vast number of engraved and painted panels of the region. Those technical and stylistic attributes are also similar to others from Southwest Europe that are dated from the end of the Late glacial period, which denotes the affiliation of this rock art facies in a graphic tradition of a broader geographic range.

The timing of the Neanderthal-associated Middle Palaeolithic demise and a possible overlap with anatomically modern humans (AMH) in some regions of Eurasia continues to be debated. The Iberian Peninsula is considered a possible refuge zone for the last Neanderthals, but the chronology of the later Middle Palaeolithic record has undergone revision and has increased the debate on the timing of Neanderthal extinction. Here we report on a study of the 5-m-thick archaeological stratigraphy of the Cardina-Salto do Boi, an open-air site located in inland Iberia, from which optically stimulated luminescence (OSL) ages were obtained for Middle and Upper Palaeolithic occupations preserved in overbank alluvial deposits. Geomorphology, archaeostratigraphy, stone-tool evolution, and OSL dating support the persistence of Neanderthals after 41 ka in central Iberia; the transition between the Middle Palaeolithic material culture and the AMH-associated Aurignacian blade and bladelet production is estimated to lie between 34.0 ± 2.0 ka and 38.4 ± 1.9 ka. Our results demonstrate that investigations focusing on different geomorphological situations are necessary to overcome the current limitations of the evidence and to establish more consistent models for Neanderthal disappearance and AMH expansion in the Iberian Peninsula.

O projecto 'Art-facts' parte da investigação dos contextos arqueológicos de abrigos pintados com Arte Esquemática, entendidos como espaços incorporadores de acção, criação e construção, e pretende fazer uma reflexão sobre arte, arquitecturas e paisagem. Neste sentido, o projecto escora-se numa análise dialéctica da arte a três escalas - a face da rocha; a arquitectura dos locais; o diálogo com a paisagem – aliada à compreensão, percepção e experiência física de espaços e materiais. Analisa quatro casos de estudo no vale do Côa, os abrigos da Ribeirinha, Colmeal, Poço Torto e Lapas Cabreiras. Esta selecção teve por base a possibilidade de contrastar a ocorrência de pintura em ambientes distintos, sobre diferentes suportes geológicos, e com alguma heterogeneidade ao nível temático, iconográfico e de conservação. Apresentamos uma breve descrição dos resultados dos trabalhos de prospecção, escavação e análise dos painéis.

We present the results of the study of lithic raw materials used in Upper Palaeolithic occupations preserved in caves, rockshelters and open-air sites from two different geological environments in Portugal. For the sites located in the Lusitanian Basin, flint or silcrete sources are easily available in close vicinity. The Côa Valley sites, located in the Iberian Massif, are within a geological environment where restricted fine-grained vein quartz and siliceous metamorphic rocks are available, but no flint or silcrete, even though both are present in the archaeological assemblages. Data from the two clusters of sites are compared with a third newly located site in the Lower Vouga valley, at the limit of the Iberian Massif with the Lusitanian Basin, where quartz vein raw material types are locally available and flint is about 40 kilometres distant. This study reveals prehistoric adaptations to these different geological contexts, with shorter networks for the Lusitanian basin sites contrasting with the long distance ones for the Côa Valley, and the Vouga site at an intermediary position. Finally, we propose that lithic raw material supply networks, defined by a GIS least-cost algorithm, could be used as a proxy not only for territoriality in the case of local and regional lithic raw material sources, but also to infer long-distance social networks between different Palaeolithic human groups, created and maintained to promote the access to asymmetrically distributed resources.

Differing from most of European Upper Palaeolithic record, the Coa Valley lithic assemblages reveal an intensive use of a large variety of quartz and quartzite available locally. New surveys of the lower Coa Valley quartz veins were carried out in order to establish potential areas of raw material exploitation by hunter-gatherers through the identification of the raw material sources present in the archaeological record. Upper Palaeolithic lithic assemblages are produced on local quartz varieties, regional fine-grained quartz veins and flint and silcrete from long distance sources. The proportion of raw material and their choice for different tool types reveal some variation through the Upper Palaeolithic sequence, but present the same diversity and large geographical range of supply. Middle Palaeolithic assemblages from the same region are essentially based on local lithic material, showing a more restricted exploitation area and revealing different technology and procurement strategies, possibly evidence of changes in mobility and social networks.

The use of quartz is well documented during prehistory, being the predominant raw material in the Upper Paleolithic sites located in NW Iberia. The prehistoric occupations from Sabor valley also present a preference for this lithology through the long occupation sequence, although a large range of regional and exogenous lithic raw materials are also knapped. Within the quartz varieties rock crystal seems to have an important role in some chronologies, especially since the Solutrean phase, regarding elongated products and small flake production. Several reduction strategies were applied to rock crystal although the unifacial exploitation from a 45° degree striking platform using the crystal natural edges as guidelines is the most common. Though there are some similarities within the use of this type of cores throughout the chronological sequence we can observe some differences, especially during the Early Mesolithic phase. In a regional perspective, it is possible to compare the quartz economy from occupations in Sabor valley to the ones from Coa valley, to the south, and discuss the role of rock crystal in Late Pleistocene inland human groups. It is clear that there was a technical ability to maximize a local lithic resource such as rock crystal which was exploited in order to achieve blanks similar to those obtained from flint cores.
