The illuminated cavern: a singular Gravettian lamp throws light upon the rock art at the cave of La Pileta (Benaoján, Málaga)

En este trabajo presentamos el estudio arqueológico, paleontológico, tafonómico, cronológico y geoquímico de una valva de ostra hallada en la cueva de La Pileta. El ejemplar procede de depósitos fosilíferos neógenos dis-tantes más de 10 km del yacimiento. Una vez adaptada, la concha fue empleada como lámpara portátil. La cro-nología 14 C/AMS de la costra carbonatada que sellaba la cubeta nos remite al periodo Gravetiense. Según diversos indicios en la lámpara, durante su vida útil se procesaron o almacenaron pigmentos. Los datos aportados informan sobre la dispersión del simbolismo del Paleolítico Supe-rior Inicial hasta el extremo sudoccidental europeo, así mismo, suma nuevos elementos al debate sobre la exis-tencia de una fase presolutrense en el arte parietal de La Pileta y, por ende, de todo el sur de la Península Ibérica.This paper presents an archaeological, paleontologi-cal, taphonomical, chronological and geochemical study of a fossil oyster valve retrieved at the cave of La Pileta. The specimen was taken from Neogene fossiliferous depo- sits located more than 10 km away from the site. The shell was worked so as to become a portable lamp. 14C/AMS dating of the carbonate crust overlying the shell indicates a Gravettian chronology. Different lines of evidence indicate that during its use life, the valve was used to harbor or process pigments. The data presented throw light on the spread of symbolism in the southwestern corner of Europe during the Early Upper Palaeolithic, and add elements to the debate on the existence of a pre-Solutrean stage in the rock art of La Pileta and, by extension, of the southern Iberian Peninsula

Los Poyos del Molinillo (Frigiliana): new site of the Bronze Age in the East Axarquía (Málaga, Andalucía)

En este trabajo damos a conocer un nuevo yacimiento descubierto recientemente en el municipio de Frigiliana. La delimitación del área denominada Los Poyos del Molinillo permitió definir la existencia de un poblado y una covacha con restos de una inhumación. El estudio de los materiales arqueológicos, que incluye cerámica, piezas metálicas o elementos de molturación, o la datación AMS obtenida, permiten adscribir el yacimiento a la Edad del Bronce y ampliar el conocimiento de esta etapa en la Axarquía oriental (Málaga, Andalucía).In this work we present a new site recently discovered in the Frigiliana municipality (Málaga). The spatial delimitation of the so called Los Poyos del Molinillo area let us define a Bronze age settlement and an inhumation burial cave. The archaeological record includes ceramic, metallic items or grinding elements, all of them belonging to the Bronze Age, as well as an AMS Radiocarbon data. This site extends the knowledge about this period in the Eastern Axarquía (Málaga, Andalucía)

Earliest Known Use of Marine Resources by Neanderthals

Numerous studies along the northern Mediterranean borderland have documented the use of shellfish by Neanderthals but none of these finds are prior to Marine Isotopic Stage 3 (MIS 3). In this paper we present evidence that gathering and consumption of mollusks can now be traced back to the lowest level of the archaeological sequence at Bajondillo Cave (Málaga, Spain), dated during the MIS 6. The paper describes the taxonomical and taphonomical features of the mollusk assemblages from this level Bj19 and briefly touches upon those retrieved in levels Bj18 (MIS 5) and Bj17 (MIS 4), evidencing a continuity of the shellfishing activity that reaches to MIS 3. This evidence is substantiated on 29 datings through radiocarbon, thermoluminescence and U series methods. Obtained dates and paleoenvironmental records from the cave include isotopic, pollen, lithostratigraphic and sedimentological analyses and they are fully coherent with paleoclimate conditions expected for the different stages. We conclude that described use of shellfish resources by Neanderthals (H. neanderthalensis) in Southern Spain started ∼150 ka and were almost contemporaneous to Pinnacle Point (South Africa), when shellfishing is first documented in archaic modern humans

Epidemiological trends of HIV/HCV coinfection in Spain, 2015-2019

Altres ajuts: Spanish AIDS Research Network; European Funding for Regional Development (FEDER).Objectives: We assessed the prevalence of anti-hepatitis C virus (HCV) antibodies and active HCV infection (HCV-RNA-positive) in people living with HIV (PLWH) in Spain in 2019 and compared the results with those of four similar studies performed during 2015-2018. Methods: The study was performed in 41 centres. Sample size was estimated for an accuracy of 1%. Patients were selected by random sampling with proportional allocation. Results: The reference population comprised 41 973 PLWH, and the sample size was 1325. HCV serostatus was known in 1316 PLWH (99.3%), of whom 376 (28.6%) were HCV antibody (Ab)-positive (78.7% were prior injection drug users); 29 were HCV-RNA-positive (2.2%). Of the 29 HCV-RNA-positive PLWH, infection was chronic in 24, it was acute/recent in one, and it was of unknown duration in four. Cirrhosis was present in 71 (5.4%) PLWH overall, three (10.3%) HCV-RNA-positive patients and 68 (23.4%) of those who cleared HCV after anti-HCV therapy (p = 0.04). The prevalence of anti-HCV antibodies decreased steadily from 37.7% in 2015 to 28.6% in 2019 (p < 0.001); the prevalence of active HCV infection decreased from 22.1% in 2015 to 2.2% in 2019 (p < 0.001). Uptake of anti-HCV treatment increased from 53.9% in 2015 to 95.0% in 2019 (p < 0.001). Conclusions: In Spain, the prevalence of active HCV infection among PLWH at the end of 2019 was 2.2%, i.e. 90.0% lower than in 2015. Increased exposure to DAAs was probably the main reason for this sharp reduction. Despite the high coverage of treatment with direct-acting antiviral agents, HCV-related cirrhosis remains significant in this population

The Mesolithic-Neolithic transition in southern Iberia

New data and a review of historiographic information from Neolithic sites of the Malaga and Algarve coasts (southern Iberian Peninsula) and from the Maghreb (North Africa) reveal the existence of a Neolithic settlement at least from 7.5 cal ka BP. The agricultural and pastoralist food producing economy of that population rapidly replaced the coastal economies of the Mesolithic populations. The timing of this population and economic turnover coincided with major changes in the continental and marine ecosystems, including upwelling intensity, sea-level changes and increased aridity in the Sahara and along the Iberian coast. These changes likely impacted the subsistence strategies of the Mesolithic populations along the Iberian seascapes and resulted in abandonments manifested as sedimentary hiatuses in some areas during the Mesolithic-Neolithic transition. The rapid expansion and area of dispersal of the early Neolithic traits suggest the use of marine technology. Different evidences for a Maghrebian origin for the first colonists have been summarized. The recognition of an early North-African Neolithic influence in Southern Iberia and the Maghreb is vital for understanding the appearance and development of the Neolithic in Western Europe. Our review suggests links between climate change, resource allocation, and population turnover. (C) 2011 University of Washington. Published by Elsevier Inc.

Bioerosive structures of polychaete annelids (Serpulidae) from the Upper Neogene of the South Iberian Peninsula

New superficial etching traces corresponding to annelids of the family Serpulidae are described. These traces present an elongated, sinuous and/or spiralated pathway in a plan view. They consist in a very shallow central channel flanked by a lateral zone that can exhibit either faint, spread, oblique grooves or perpendicular, dense lines. The external part of this zone shows normally, a very narrow margin. The flanks of the traces are nearly parallel in the proximal part and clearly divergent in the opposite en
