The fluvial capture of endorheic basins represents a milestone in basin chronology, implying a profound disequilibrium that triggers critical geomorphological, sedimentological, paleogeographic, and even paleoecological transformations. The primary goal of many geomorphological studies is to determine the timing of endorheic-to-exorheic transitions with the objective of unveiling the dynamics that follow the capture event. The age of the Guadix-Baza Basin capture in the Central Betic Cordillera (S Spain) remains a subject of controversy, with proposed estimates ranging from 17 to 600 ka. In this study, we present new 234U/230Th and optically stimulated luminescence ages from exorheic deposits exposed within the basin's main fluvial valley, the Guadiana Menor River. We acquired the oldest numerical age recorded to date for a postcapture deposit within the basin. This age corresponds to a travertine platform formed 240.8 ± 25 ka on a surface level that was already incised into the glacis surface at approximately 250 m. Using these data, we estimate that basin capture took place earlier than ca. 240 ka, plus the time required for the river to incise 250 m to the position of the travertine. Furthermore, the proximity of the Matuyama-Brunhes reversal (781 ka) to the top of the endorheic succession and the ages of the paleontological sites (> ca. 750 ka) throughout the basin suggest that the capture could have occurred earlier than the oldest previously proposed age of 600 ka.

In Iberia, ditched enclosures appeared during the Copper Age (late fourth to third millennium bc). These sites are linked by their circular organization, communal labour investment, and complex temporality, but vary markedly in their distribution, function, and scale. Though archaeological attention has focused on 'mega-sites', an assessment of small-scale enclosures in marginal environments is key to understanding the social dynamics that facilitated their emergence. Here, the authors present results from Los Melgarejos (Getafe, Spain), the first Iberian Chalcolithic enclosure (3 ha) to be extensively documented, with all structures and seven per cent of the enclosure ditches excavated. Bioarchaeology, mortuary archaeology, isotope analyses (δ13Cco, δ13Cap, δ15N), and radiocarbon dating are employed to compare lived experiences of diet, stress, trauma, and funerary ritual at small- and large-scale enclosures. Comparisons with the mega-site of Marroquíes reveal similarities in lived experience and ritual practice, as well as regional differences in dietary isotopes, highlighting the utility of multiscalar comparisons for understanding prehistoric lifeways.

Book review: Catlos B.А. Kingdoms of Faith: A New History of Muslim Spain. – Moscow: Medina ID, 2024. – 608 p.The Muslim period in the history of Spain is mostly associated with Moorish art and the brutal but just Reconquista that culminated with the fall of Muslim Granada. However, the book «Kingdoms of Faith: A New History of Muslim Spain» by B. Catlos tells a very different story of the Muslim Spain known as al-Andalus. The author intends to offer a new vision of the Arab-Berber conquest of Spain with readers who might not be closely familiar with this period, focusing on the sociocultural interaction of the religious communities that inhabited the Iberian Peninsula at the time. The work combines well-known and little-known historical facts into a single narrative line that encapsulates nine centuries of Iberian history, from the Muslim conquest of the Visigothic Kingdom in 711 to the expulsion of the Moriscos (Muslims converted to Catholicism) from Spain in 1614. This is a review of a book that reconsiders common myths about the Arab-Muslim state of al-Andalus, Reconquista and the phenomenon of convivencia.

No country is immune to the electoral success of populist radical right (PRR) parties: Spain and Portugal seemed to be the exception to this rule because, for decades, PRR parties remained relegated to the margins of the Iberian political systems. However, in 2019 VOX and Chega gained parliamentary representation: how did they manage to obtain their historic electoral breakthrough? From a supply-side perspective, we use the Party Manifesto dataset to show that VOX and Chega chose to position themselves within the existing political space and cleavages in ways that set them apart from the competition. VOX exploited the Spanish centre-periphery cleavage insisting on strong nationalist elements while advocating for increased centralization, while Chega insisted on personal freedom and welfare limitation to break the ties with the political system born out of the Carnation Revolution.

Over the last several decades, the application of aDNA and strontium isotope analyses on archaeologically recovered human remains has provided new avenues for the investigation of mobility in past societies. Data on human mobility can be valuable in the reconstruction of prehistoric residential patterns and kinship systems, which are at the center of human social organization and vary across time and space. In this paper, we aim to contribute to our understanding of mobility, residence, and kinship patterns in late Prehistoric Iberia (c. 3300–1400BC) by providing new strontium data on 44 individuals from the site of Humanejos (Parla, Madrid). The study presented here is multi-proxy and looks at these new data by interweaving biological, chronological, and archaeological information. This analysis found that 7/44 individuals buried at Humanejos could be identified as non-local to the necropolis. Although more men (n = 5) than women (n = 2) were found in the non-local category, and more non-local individuals were identified in the pre-Bell Beaker (n = 5) than in Bell Beaker (n = 1) or Bronze Age (n = 1), we find no statistically significant differences concerning sex or time period. This contrasts with other archaeological datasets for late prehistoric Europe which suggest higher female mobility, female exogamy, and male-centered residential patterns were common. At Humanejos, we have also identified one non-local female whose exceptional Beaker grave goods suggest she was an individual of special status, leading to additional questions about the relationships between gender, mobility, and social position in this region and time period.

Today, mercury is a matter of concern for health and environmental authorities across western countries, and legislation has been passed and programs have been implemented for its total elimination from human activity. But this was not always the case: mercury and its compounds have been highly appreciated and used since remote times all over the world with very diverse purposes ranging from decorative, medicinal, metallurgical and symbolic. In particular, cinnabar (HgS, mercury sulfide), a mineral of an intense red color, has been considered in many cultures as an exotic raw material, highly valued and associated with the elites and sacred practice. In this paper, we examine one such case, set almost 5000 years ago, in Copper Age Iberia, by investigating mercury exposure through human bone. The study presented here includes a total of 170 samples from 70 different human individuals and 22 animals (plus one soil sample) from the Copper Age mega-site of Valencina, south-western Spain. It is the largest ever single-site study of exposure to mercury based on human bone in combination with cinnabar use. Abnormally high values are recorded in some individuals dating between 2900 and 2650 BC, especially in those buried in remarkable tombs belonging to the social elite of this period, but high levels of mercury are also recorded in the rest of the population. Three lines of interpretation are used to explain these results, including the manipulation of cinnabar (grinding it into powder, mixing it with other substances, using it for the decoration of objects, buildings and the human body), its direct consumption through ingestion or inhalation by a 'special' social group and the contribution of environmental factors. Based on the currently available evidence, which is carefully reviewed, Valencina represents the most intense and prolonged case of exposure to mercury recorded in human history, which makes it an important site to assess the long and complex history of use of this substance.

The Vallparadís Section encompasses various geological layers that span a significant chronological range, extending from the latest Early Pleistocene to the early Middle Pleistocene, covering a timeframe from approximately 1.2 to 0.6 Ma. This period holds particular importance, as it coincides with a significant climatic transition known as the Early–Middle Pleistocene Transition, a pivotal phase in Quaternary climatic history. This transition, marked by the shift from a 41,000-year obliquity-driven climatic cycle to a 100,000-year precession-forced cyclicity, had profound effects on the Calabrian carnivorous mammal communities. Notably, the once diverse carnivore guild began to decline across Europe during this period, with their last documented occurrences coinciding with those found within the Vallparadís Section (e.g., Megantereon or Xenocyon). Concurrently, this period witnessed the initial dispersals of African carnivorans into the European landscape (e.g., steppe lions), marking a significant shift in the composition and dynamics of the region's carnivorous fauna.

The objective of this article is to reflect on the connections between early modern Spanish empire building and expansionism by Christian principalities during the medieval period. The core argument, which is, by necessity, reductionist owing to the brevity of this article, is that while late medieval / early modern attitudes about conquest and world domination drew heavily on the history, models, and practices of earlier centuries, the ideology of empire that emerged from the later fifteenth century was distinct in two primary, interrelated respects. First, the increased political fragmentation within Christian-ruled lands intensified the more localized, inward-looking dynamic of the territorial struggles against Muslim regimes that contrasted with the more global outlook of later medieval and early modern Christian imperialism. Second, the distinct ideologies of these sometimes coordinated but often competitive earlier expansionist efforts were founded upon different justificatory conceptions of sacred and secular history that, again, were, in essence, much more peninsular in their orientation.

Muslim religion has strict rules to determine what kinds of foodstuffs, and under what circumstances, are deemed appropriate for consumption. Fishes are not an exception to this rule and features such as body shape or the presence and conspicuousness of scales dictate whether certain species are acceptable or rejected. In this paper, an overview of the Iberian ichthyoarchaeological record from Muslim sites is presented to ascertain whether differences with Christian sites existed in terms of these characters and to what extent these allow one to take fish assemblages as cultural proxies of archaeological deposits. In the case of coastal (production) sites, we also consider whether the peculiarities a given fish assemblage exhibit reflect instead certain environmental features such as the biotopes where a given local fishery operated.

The Phoenician colony of La Fonteta in southeastern Iberia holds significant importance for understanding Phoenician settlement patterns in the region. While previous research has primarily focused on wheel-thrown ceramics indicative of the new technological advancements and trade networks implemented after the Phoenician arrival, handmade ceramics have been somewhat overlooked despite their prevalence in the Early Iron Age (EIA) contexts. Our study, based on the analysis of 36 individuals from recent excavations at La Fonteta, sheds light on the technological aspects (temper choice and estimated firing temperature) and mobility patterns associated with handmade ceramics in this context. Contrary to previous assumptions, our findings indicate that handmade ceramics played a crucial role in regional and broader exchange systems, possibly with limited ties to wheel-thrown ceramics. Moreover, regional mobility seems to have been prominent, likely stemming from local networks and technological frameworks established during the preceding Late Bronze Age (LBA) period.

In plate kinematic reconstructions, the restoration of rifted margins and their fossil equivalents exposed in orogens remains challenging. Tight fit reconstructions rely on the mapping of margins rift domains, their restoration to their pre-rift crustal thickness, and the removal of the oceanic and exhumed mantle domains. At present-day margins, high-resolution wide-angle seismic imaging allows mapping and measurement of rift domains; however, restoring fossil margins is trickier because they are largely overprinted and partially lost during convergence. Here, we present a new kinematic model for the Mesozoic rifting along the Tethys–Atlantic junction, which relies on two assumptions: (1) the width of the fossil Alpine Tethys rift domains was comparable to that of their present-day analogs, and (2) the necking zones of the former tectonic plates can be mapped, dated and used as kinematic markers. This reproducible workflow allows us, for the first time, to restore the rifted margins of the Alpine Tethys. Our reconstruction shows: (1) a westward propagation of extension through the Ionian, Alpine Tethys and Pyrenean rift systems from the Triassic to the Cretaceous, (2) the segmentation of the Mesozoic Tethyan rifted margins by strike-slip corridors, (3) the opening of an oceanic gateway at 165 Ma as mantle was exhumed along the entire Alpine Tethys and (4) the subdivision of the Mesozoic oceanic domain into compartments that were later consumed during subduction. This new model is supported by published data from the Alps, the Ionian Sea, the Pyrenees and the southern North Atlantic. [ABSTRACT FROM AUTHOR]

The complete mitochondrial genomes of two Iphiclides species, namely I. podalirius and I. podalirinus, were sequenced, assembled, and reported in this article. Both genomes comprise 37 genes, with 13 protein-coding genes, 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. The gene orders and alignments agree with the reported mitogenomes of Leptocircini butterflies, while the start codon for the COX1 gene in I. podalirinus is CGA instead of the commonly seen ATN type. Codon preference shows that methionine and tryptophan are the poorest, while arginine, leucine, and serine are the richest. Phylogenetic analysis using Bayesian Inference shows both Iphiclides species are sister to the genus Lamproptera and are basal to all remaining Leptocircini species. The Kimura 2-parameter (K2P) distances of I. podalirinus from I. podalirius exceed 5%, demonstrating its solid species status. The K2P distance between the North African feisthamelii and podalirius exceeds 2%, indicating the reasonable elevation of I. feisthamelii to the full specific level as its type locality is Algeria. Future research is required to tackle the relationship between the Iberian feisthamelii and podalirius using more evidence. [ABSTRACT FROM AUTHOR]

My analysis in this paper centers on Miguel de Unamuno's multifaceted engagement (commentary, translation, poetic response) with Antero de Quental's metaphysically-inclined sonnets. Like Unamuno, I focus on the sonnets "Redenção" and "Na mão de Deus." I first demonstrate how Unamuno unsuccessfully attempts to reconcile Quental's poetic descriptions of death as liberation, and of the individual's reabsorption in death into the universal consciousness, with his agonized faith in a personal God and his New Testament-derived belief in humanity's redemption from sin and salvation by Jesus Christ. I then argue that while Unamuno may have misinterpreted Quental, his misreading was nonetheless productive in that it furnished him with an Iberian exemplar of the sentimientotrágico de la vida – though I contend that Unamuno's elevation of Quental to the status of tragic exemplar is nonetheless misplaced [ABSTRACT FROM AUTHOR]

Climate change and associated shifts in temperature and precipitation patterns have become an increasing concern as drivers of ongoing biodiversity loss. The Mediterranean region is particularly vulnerable, being both a biodiversity hotspot and a region very prone to desertification. Freshwater mussels are amongst the most threatened invertebrate taxa worldwide. Unio tumidiformis is an endemic and endangered species restricted to the southern Iberian Peninsula, living in temporary Mediterranean-type streams. Freshwater mussels need a fish host for successful larval transformation, meaning U. tumidiformis must belong to the genus Squalius. The main objective of this study was to evaluate the vulnerability of U. tumidiformis to climate change, by studying its population genetics and evolutionary history, its current and future habitat suitability, and that of its hosts. Genetic population structure and diversity were assessed using Single-Nucleotide Polymorphisms through Genotyping by Sequencing and used to infer species evolutionary history. The species potential distribution was modeled using an ensemble forecasting approach, and future shifts in habitat suitability were assessed with the projected climate data layers from Worldclim. Most populations showed extreme genetic differentiation (Fst up to 0.745), even from close neighboring ones. Upper Guadiana populations were more diverse and less differentiated. We hypothesize that U. tumidiformis originated in Upper Guadiana and followed the same colonization routes as their hosts with numerous founder effects and bottlenecks. Our results also predicted a reduction of 99% of climatically suitable areas for U. tumidiformis in the Iberian Peninsula until 2040. For the fish hosts, a maximum 42% reduction in suitable areas was estimated throughout the century, with remaining adequate habitats in the north. Our results suggest that difficult conservation options are necessary, prioritizing the preservation of populations, translocations to the northern area of its historical range and stream engineering to increase resilience to droughts.

This article serves as an introduction to a discussion on cultural practices relating to death in late medieval Iberia. It contends that an intersectional approach is necessary to study this topic because, while all humans die, the way they are buried, memorialized, and remembered is tied to factors such as culture, religion, class, wealth, gender, tradition, legal practices, medical knowledge, technology, and historical context. The second part of this introduction offers an overview of the articles that form this special issue, the goal of which is to gender death in order to better appreciate how late medieval women prepared for it, and how they were commemorated by those they left behind.

Enicocephalomorpha, also known as uniqueheaded bugs, are a seldom-collected infraorder of heteropteran insects whose evolutionary relationships have puzzled entomologists for more than a century. Unique-headed bugs are exceptionally rare in the fossil record, which hinders our understanding of the morphological transformations of the lineage across time and also affects the calibration of molecular clock estimates used to date the origins of the infraorder. Here, we report the discovery of Enicocephalinus ibericus sp. nov. from Iberian amber in the Ari~no deposit in Spain, early Albian (Early Cretaceous) in age. The new species represents the second oldest fossil enicocephalomorphan to date, and the second record of this infraorder from European deposits. Remarkably, the closest relative of E. ibericus is the congeneric E. acragrimaldii Azar from Lebanese amber that is c. 20 myr older (Barremian), indicating a long-term persistence of the Enicocephalinus lineage across geological time. A review of the existing literature enabled us to record a total of 20 congeneric insect species that have been found in both Lebanese and Iberian ambers, suggesting the existence of previously underappreciated entomofaunal connections between southern Laurasia (the European archipelago) and northern Gondwana during the Cretaceous. We show that the palaeoentomological record holds remarkable potential for elucidating the faunistic exchanges and palaeobiogeographical patterns in the peri-Tethyan region during the Cretaceous.

The genus Equus was represented on the Iberian Peninsula by four species during the late Quaternary: the wild, now extinct, E. ferus (wild horse) and E. hydruntinus (European wild ass) and the extant, domestic E. caballus (horse) and E. asinus (donkey). The distribution and timing of the extinctions of the wild species and arrival of the domestic species is important to understand the changing environment and cultures through this dynamic period in one of the three southern Pleistocene glacial refugia in Europe. Here we collected data from all zooarchaeological studies that meet basic completeness criteria from the Palaeolithic to the Bronze Age (45–3.2 ka bp) and analysed the equine data in light of other large mammals at the same sites in order to document the species turnover and distributions through this culturally and ecologically dynamic period. The vast majority of Palaeolithic Equus were confidently identified as E. ferus, and by the Bronze age as E. caballus, with much uncertainty in between. Over time the larger equids (horses) were much more common than the smaller equids (asses). Equids were not common, but they were distributed across the southern Iberian peninsula through the Chalcolithic, and then appear to have become restricted to the drier eastern region in the Bronze Age. These analyses indicate that both E. ferus and E. hydruntinus went extinct by the end of the Pleistocene/Palaeolithic in Andalucia. Not all communities maintained equal numbers of equids, and their distribution changed with the changing climate through time, most notably between the Chalcolithic and the Bronze Age when confidence in species identification and local density of horses increase, but the distribution is restricted to the drier eastern region.

The dataset presented here is the quartzite and quartz reference collection from the National Research Centre of Human Evolution of Spain (CENIEH), Burgos. This dataset or online lithotheque consists of 73 archaeological and geological samples obtained in different projects in which the CENIEH has been involved in the last 15 years. Most of the samples described here were collected from the Iberian Peninsula, while a few others were chosen from Eastern Africa. The samples have been petrographically described using thin section, stereomicroscopy and de visu petrographic observations and they have been characterised according to their petrogenesis. This dataset consists of a comprehensive report, an alphanumeric dataset with relevant features and an extensive picture archive. The dataset collection is stored at the CENIEH and it is open for researchers who want to use it for establishing their reference collection and describing quartzites in archaeological contexts.

Abstract The Earth’s magnetic field originated in the fluid core, the so-called core field, is the dominant contribution to the geomagnetic field. Since ancient times, the core geomagnetic field has been used primarily for geographical orientation and navigation by means of compasses. Nowadays, thanks to the large amount of geomagnetic data available, core field models can be developed on a global or regional scale. Global models resolve large-scale geomagnetic field features, while regional models can resolve greater detail over a particular region. The spherical harmonic cap analysis is a widely used technique for regional-scale modelling of the geomagnetic field. In this work we have developed a regional model of the core field and its secular variation between 2014.5 and 2020.5 over the Iberian Peninsula, based on data from Swarm satellites, geomagnetic observatories and repeat stations. Its performance has been validated by comparing the fit to the available geomagnetic data using the regional model and the global models IGRF and CHAOS over the whole spatio-temporal range studied. In order to optimise the model, a detailed study of its input parameters has been carried out, showing that not all parameters have an equal influence on the modelling. This new model reproduces the input data with a root mean square error of 2.9 nT, improving the outcome of global models on this region. The results of this work will allow the Spanish Instituto Geográfico Nacional to produce the magnetic cartography of Iberia and the Balearic Islands in 2020.0, which for the first time will be based on a regional core field model, replacing the polynomial variation method used in the past.

Palaeolithic sites are complex palimpsests due to the recurrent presence of human groups and carnivores through time, as documented in several European caves and rock shelters. Within these contexts, it can be challenging to identify the main contributors to bone accumulations and interpret human subsistence strategies and the role of carnivores. Consequently, taphonomic analyses are crucial for distinguishing the origins of these occupation episodes. One example of alternating occupations is found at El Castillo cave (Cantabria, Spain), specifically in the so-called Transitional Aurignacian level (∼46-42 ka uncal BP). According to a recent study conducted at this level (Luret et al., 2020), the human groups had a hunting specialisation focused on red deer, while carnivores had little influence on the assemblage. However, these interpretations were based only on the faunal assemblage from the recent excavations (1980–2011). A previous excavation phase was conducted on this site from 1910 to 1914, and after that, the faunal remains recovered were separated across several institutions, lacking a complete archaeozoological and taphonomic analysis of the whole level. In this work, a new taxonomic assessment and, for the first time, a taphonomic study of the macrofauna recovered in the Aurignacian Delta level during the initial excavations, stored at Museo Nacional y Centro de Investigación de Altamira (Cantabria, Spain), is carried out. This work provides new information about the human and carnivore groups that occupied El Castillo, constructing new hypotheses to interpret this relevant archaeological level.

The present study seeks to better understand the coupling of social and biophysical systems during the late Pleistocene and Holocene, a period characterized by changing interglacial conditions as well as human population expansion and intensified ecosystem management. The approach consists of a combination of patch-based archaeological survey methods, sediment column sampling for paleoenvironmental data, geospatial analysis, and machine learning for chronological unmixing, allowing the systematic evaluation of the distribution and intensity of prehistoric land use in the study area of eastern Mediterranean Iberia. Occupational and Land Use Intensity maps developed from continuous distributions of surface artifacts as well as a summed probability density curve developed from 14C dates indicate low but steady human presence in the study area during the Middle Paleolithic and Upper Paleolithic with a marked decrease of human presence across the Pleistocene/Holocene boundary. The Early (and Middle) Neolithic saw the most ubiquitous and intensive occupation of the study area followed by a significant decline during the Late Neolithic/Chalcolithic. The charcoal analysis also supports this pattern. Early Neolithic farming strategies may not have been damaging initially during the climatic regime of the Early Holocene but exacerbated the impacts of higher temperatures and summer droughts, with a loss of the most productive farmland, seen at the onset of the Late Neolithic. Similar boom-bust population trends have been documented throughout Europe during these same time spans and may indicate a recursive interaction or "coupling" between global and regional climate events and human land use strategies.

A morphometric analysis has been carried out on 140 specimens of the polyconitid rudist, Polyconites hadriani Skelton et al. from the Aptian carbonate platforms of the western Maestrat Basin, eastern Iberia, in order to compare the shapes of shells from platform-top to uppermost slope (pl) facies with those from nearby slope (sl) deposits. Comparisons between shells from these two palaeoenvironmental settings yielded the following results: (1) sl shells reached significantly larger sizes than pl shells (using commissural diameters as proxies for size), while no significant differences were found between the commissural diameters of lower and upper Aptian sl specimens; (2) relative growth of the dorso-ventral, and antero-posterior commissural diameters did not deviate significantly from isometry in either setting; (3) but in pl shells, radial growth of the attached valve's ventral margin was positively allometric relative both to commissural size and to radial growth of the dorsal margin, which had the effect of causing the commissural plane to tilt upwards ventrally during growth, in the manner of flat oysters; and (4) in sl shells, by contrast, radial growth of the ventral margin relative to the other variates did not deviate significantly from isometry, so the commissure was evenly raised during growth - with the exception of some crowded specimens, which did show some upward tilting of the ventral margin. These subtle differences of shell shape arising between coeval and contiguous populations are interpreted to reflect ecophenotypic variation in a single species resulting from adaptive plasticity of growth in response to differing conditions in the two settings. Although previous morphometric studies of other rudist taxa have focused on identifying intraspecific variation, most notably in relation to phyletic size increase, this is the first to apply the approach specifically to the recognition of ecophenotypic variation in a rudist species. A critical eye thus needs to be cast over the huge historical legacy of rudist 'species' arbitrarily distinguished on typological criteria. [ABSTRACT FROM AUTHOR]

This essay introduces a Special Issue exploring the history of Iberian anarchism in the twentieth century. It highlights the paucity of research on Portuguese anarchism in general, and argues that the well-established field of Spanish anarchist history can profit from greater insight into the development of anarchism in Iberia as a whole. The essay then showcases the five articles which comprise the Special Issue, drawing particular attention to their methodological contributions in fields such as urban space, biography, and transnationality and how these can help to recover historical perspectives marginalised by incomplete narratives.

This article analyses new prehistoric evidence of trepanation from a collective burial site in the south-eastern Iberian Peninsula. The trepanned individual was documented in the Chalcolithic burial site of Camino del Molino, where 1348 individuals (30.7 % non-adults and 69.3 % adults) were deposited in two contiguous funerary phases, making it a reference site for the knowledge of Recent Prehistoric populations. The individual has been sexed using traditional anthropological methods and ancient DNA. C14 dating has also been obtained. The lesion has been analysed macroscopically and microscopically using SEM. The skull under study belonged to an adult female deposited in the second burial phase (2566–2239 years cal BCE). It exhibits in the anterior region of the right temporal fossa two contiguous and partially overlapping holes that correspond to two trepanations performed using the scraping technique. It is a double cranial trepanation with signs of bone remodelling suggesting survival from surgery. No pathological signs were identified potentially associated with the intervention. This is the second case of surgical interventions in the geographical area of study and one of the few evidences of this practice in women during prehistoric times. So far only the articulated skeletons from this burial have been thoroughly analysed. Further intensive review of skull collection is advised to learn more about these surgical interventions in Copper Age and to go deeper into the causes that motivated their execution.

In the late ninth century, a series of chronicles from the Christian kingdom of Asturias staked a claim on Visigothic identity, and thus ancestral legitimacy to rule in Iberia, for Asturias and its kings. Connecting Pelayo, the first king of the Asturian kingdom, to the last Visigothic kings and crafting his image as an ideal Goth and Christian was essential to this process. Informed by scholarship on "borderlands" and boundary-making, this article demonstrates how the chroniclers renegotiated the parameters of Gothic identity to impose the idea of a strict border between legitimate and illegitimate, good Catholic and heretic, and loyalty and disloyalty. In doing so, they provided Pelayo with a layered and flexible Gothic-Christian-Asturian identity. [ABSTRACT FROM AUTHOR]

This study analyses the funerary activity of small collective tombs with a limited number of individuals in the southwest of the Iberian Peninsula during the Copper Age. These small burial spaces are one of the most frequent funerary manifestations and one of the most common forms of megalithic monumentality in the complex societies of this geographical area. The necropolis of La Orden-Seminario is put forward as a detailed case study, applying a multi-method approach that integrates the interrelated analysis of architecture, stratigraphy, funerary deposits, bioanthropological indicators, and chronological sequences. The research makes it possible to identify the overarching features that characterise these collective funerary activity: (a) the architectural and functional similarity between the hypogea and tholoi; (b) the periodic remodelling and reorganisation of the burial spaces; (c) the formation of superimposed funerary levels articulated in various phases; (d) the short periods of time in each level, with a concentration of 1–5 generations; (e) the coexistence of primary and secondary funerary deposits; (f) the low minimum number of individuals and the non-existence of dissymmetric practices according to sex and/or age; (g) the uniformity of the grave goods, the fragmentation of the objects, and the deposition of offerings; and (h) reuse during the Early Bronze Age.

Our understanding of Chalcolithic settlements in southern Iberia (c. 3200–2200 bce) has changed dramatically in recent decades. Instead of clearly bounded and dense settlements, archaeology is establishing a range of site types, some sparsely settled, some quite large. Such varied settlement typology is now understood as being part of a thriving period of development, which included monumental tombs, high-quality craft organisation and highly dynamic exchange networks. This article presents recent work around the River Antas in Almeria, Spain, which has revealed a complex settlement network along the river for the period in question. This new evidence challenges our understanding of prehistoric habitation in the area and poses new questions about major settlement pattern changes in the prehistory of the region.

La prevalencia del espejo griego en las construcciones identitarias generadas en Iberia ha hecho que el prisma romano o, mejor dicho, los estudios centrados en las fuentes literarias latinas no se hayan prodigado. Por esta razón, nuestra intención en este trabajo es valorar el peso de ciertos autores latinos en la progresiva construcción etno-geográfica de la península ibérica durante el periodo de conquista. Así, nos acercaremos a obras de naturaleza muy dispar ‒ el AUC de Tito Livio, la producción cesariana, las RG augusteas o la NH pliniana‒ que, para estos contextos, han quedado eclipsadas por el relato de Estrabón y de sus ilustres predecesores.

An evolutionary approach on the study of the funerary systems in Late Prehistory allows recognizing diverse contexts of social crises in the north of Iberia. The analysis of the radio-chronological data that we have compiled indicates five phases of use—with the newness of identifying two different cycles during the Late Neolithic—and of subsequent ‘abandonment’ in the megaliths; this is reduced to two phases in the case of the sepulchral caves. We interpret the radio-chronological results through an examination of the material culture present in the graves and dynamics of the megalithic architecture. In addition, we contrast our results with different approaches, carrying out a complementary multidisciplinary approach. In this regard, we found that megalithism served as a vehicle for responding to the different crisis and changes faced by increasingly complex and unequal human groups.

A través de la presentación de ciertos objetos que aparecen en inventarios romanos de los siglos XVI y XVII y las trayectorias de ciertos mercaderes portugueses presentes en la ciudad en el mismo periodo, el artículo considera a estos como intermediarios culturales. Por medio de sus vínculos presuntos o reales con el mundo ibérico y sus extensos territorios y sus lazos con la burocracia de la Iglesia Católica o vínculos con el mundo de la Curia romana, estos individuos habrían sido los agentes naturales para hacer llegar objetos de una supuesta procedencia oriental llegar a la ciudad. El artículo también considera cuán problemática y ambigua es la designación de oriente y cómo sus múltiples significados en la época deben ser tomados en consideración a a la hora de atribuirla a los objetos.

Weathering constitutes one of the most investigated taphonomic processes for understanding the formation of archaeological and palaeontological assemblages. Despite being studied for decades through numerous monitoring experiments, no homogeneous methodology exists to compare the results obtained in different regions and climates. Here, we present the protocols and the preliminary results of an experimental research started four years ago in a coastal and inland location within the Cantabrian Region (northern Spain) to assess the influence of the weathering process in an Atlantic climate. This experiment allows evaluation of the preservation of faunal assemblages in regional open-air sites throughout the Middle and Upper Palaeolithic. We conduct this experiment within the Global Weathering Project of the International Council for Archaeozoologists (ICAZ), an international network of archaeozoologists and taphonomists who coordinates the same experiment worldwide. The experiment planned to last 18 years consists on recording the weathering stages suffered on the cow ribs disposed on the surface of a fenced enclosure under the protection of a cage, separated from the soil by a neutral inorganic substrate and close to a weather station where the temperature, humidity, rainfall, wind and sun exposure values are daily recorded.

The Gravettian site of Fuente del Salín Cave is located in the northern Iberian Peninsula (Cantabrian Region, Spain). In 2016, excavations conducted at the site yielded numerous faunal remains, including mammals and fish. Researchers also recovered molluscs remains during the 1990, 1991, and 2000 campaigns. This study presents the results of the archaeozoological and taphonomical analyses of the large mammals and fish remains recovered during these excavations. At Fuente del Salín Cave, a high level of bone fragmentation and the presence of burning damage characterizes the faunal assemblage. Taxonomy of large game shows diverse habitat exploitation, such as coastal valleys and plains (red deer, Cervus elaphus; horse, Equus ferus) as well as rocky landscapes (Iberian ibex, Capra pyrenaica; and chamois, Rupicapra rupicapra). Additionally, fish remains show the presence of salmonids (Salmo sp.), cyprinids, and haddock (Melanogrammus aeglefinus), indicating the exploitation of coastal, demersal, and riverine species. The taphonomic analysis of the mammals revealed burning damage concentrated on axial elements and epiphyses, characterized by temperatures typical of carbonization or calcification. The scarcity of carnivore gnawing marks and the presence of butchering marks prove that humans were the main accumulators at Fuente del Salín Cave. Concerning fish, most remains correspond to spines, branchial spines, ribs, and vertebrae, indicating humans processed fish by removing these elements for consumption. Based on our results, Fuente del Salín Cave provides an essential record of the subsistence strategies of the inhabitants of the Cantabrian Region during the Gravettian.

The Earth's magnetic field originated in the fluid core, the so-called core field, is the dominant contribution to the geomagnetic field. Since ancient times, the core geomagnetic field has been used primarily for geographical orientation and navigation by means of compasses. Nowadays, thanks to the large amount of geomagnetic data available, core field models can be developed on a global or regional scale. Global models resolve large-scale geomagnetic field features, while regional models can resolve greater detail over a particular region. The spherical harmonic cap analysis is a widely used technique for regional-scale modelling of the geomagnetic field. In this work we have developed a regional model of the core field and its secular variation between 2014.5 and 2020.5 over the Iberian Peninsula, based on data from Swarm satellites, geomagnetic observatories and repeat stations. Its performance has been validated by comparing the fit to the available geomagnetic data using the regional model and the global models IGRF and CHAOS over the whole spatio-temporal range studied. In order to optimise the model, a detailed study of its input parameters has been carried out, showing that not all parameters have an equal influence on the modelling. This new model reproduces the input data with a root mean square error of 2.9 nT, improving the outcome of global models on this region. The results of this work will allow the Spanish Instituto Geográfico Nacional to produce the magnetic cartography of Iberia and the Balearic Islands in 2020.0, which for the first time will be based on a regional core field model, replacing the polynomial variation method used in the past.
