Arte paleolítico en Gorham's Cave (Gibraltar)

En este trabajo presentamos las novedades sobre el arte paleolítico de la cueva de Gorham. En el apartado mobiliar, abordamos una aproximación multidisciplinar en la que se analizan los datos petrográficos, deposicionales, diagenéticos, tafonómicos y antrópicos (técnicos o iconográficos) identificados en dos plaquetas de arte mueble. El arte parietal de Gorham se amplía con las manifestaciones localizadas en una Galería ubicada al final del cavernamiento. En ambos casos, la procedencia estratigráfica o los rasgos estilísticos permiten su atribución al Magdaleniense.We present the news on Palaeolithic art of Gorham’s cave. In paragraph of mobiliary art, we discuss a multidisciplinary approach in analyzing the petrographic, depositional, diagenetic, taphonomic and anthropic (technical or iconographic) data identified of two plaquettes of portable art. The Gorham’s cave art expands with the paintings located in the gallery located at the end of the cave. In both cases, the stratigraphic provenance or stylistic features allow its attribution to the Magdalenian

Culto y culturas en la cueva de Gorham (Gibraltar): La historia del santuario y sus materiales inscritos

This paper presents an updated overview of the ongoing archaeological research carried out in the Protohistoric sanctuary of Gorham’s Cave (Gibraltar). It is based on the results of recent excavations, focusing on incised pottery with inscriptions or other marks. The catalogue of inscriptions includes both Phoenician and Graeco-Iberian examples, which could be related with the deposition of votive offerings from Archaic to Hellenistic periods.El artículo presenta un nuevo estado de la cuestión arqueológico sobre el santuario protohistórico de la Cueva de Gorham (Gibraltar) a la luz de los resultados de las recientes campañas de excavación y estudia los materiales cerámicos con inscripciones u otro tipo de marcas hallados en la cueva. El catálogo incluye un nuevo grafito fenicio y una inscripción greco-ibérica que se relacionan con las ofrendas depositadas en el lugar desde época arcaica hasta el periodo helenístico

The large biogeographical significance of this territory and the outstanding availability of sedimentary archives have made this region a hotspot of paleobotanical research in the Iberian Peninsula. Specifically, the organic deposits on El Asperillo Cliff have been studied during the past few decades from the geomorphological and paleobotanical (pollen, macrofossils) points of view. However, large uncertainties remain concerning the chronology of certain sections of the exposed profile and the paleobotanical potential of this site has not been fully exploited yet. In this study, we revisited El Asperillo with the aims of completing the paleobotanical record and refining the chronology of this site. The age of the studied deposits ranges from ca. 22,000 to 30,900 cal. yr BP according to the radiocarbon dates obtained, thus embracing the particularly cold and dry Heinrich Event 2 and the Last Glacial Maximum. Our palynological results allow inferring the presence of a coastal marshland system. Additionally, the new pollen records highlight the relevance and diversity of pines (Pinus nigra-sylvestris type, P. pinaster, P. halepensis-pinea type) in the Late Pleistocene landscape of Doñana, reinforcing the native status of pines. Last but not least, the results stress the persistence of a highly diverse woody flora in Doñana during the harshest periods of the last glacial cycle, highlighting the importance of this enclave in postglacial vegetation recolonization of the Iberian Peninsula.The development of this work was supported by Projects FEDER/Ministry of Science and Innovation, Agencia Estatal de Investigación CGL-BOS2015-68604-P and PID2019-1049449GB-I00), 261-2011 Organismo Autónomo de Parques Nacionales and Fundación Séneca grant 20788/PI/18Peer reviewe

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

Genomic investigations of unexplained acute hepatitis in children

Since its first identification in Scotland, over 1,000 cases of unexplained paediatric hepatitis in children have been reported worldwide, including 278 cases in the UK1. Here we report an investigation of 38 cases, 66 age-matched immunocompetent controls and 21 immunocompromised comparator participants, using a combination of genomic, transcriptomic, proteomic and immunohistochemical methods. We detected high levels of adeno-associated virus 2 (AAV2) DNA in the liver, blood, plasma or stool from 27 of 28 cases. We found low levels of adenovirus (HAdV) and human herpesvirus 6B (HHV-6B) in 23 of 31 and 16 of 23, respectively, of the cases tested. By contrast, AAV2 was infrequently detected and at low titre in the blood or the liver from control children with HAdV, even when profoundly immunosuppressed. AAV2, HAdV and HHV-6 phylogeny excluded the emergence of novel strains in cases. Histological analyses of explanted livers showed enrichment for T cells and B lineage cells. Proteomic comparison of liver tissue from cases and healthy controls identified increased expression of HLA class 2, immunoglobulin variable regions and complement proteins. HAdV and AAV2 proteins were not detected in the livers. Instead, we identified AAV2 DNA complexes reflecting both HAdV-mediated and HHV-6B-mediated replication. We hypothesize that high levels of abnormal AAV2 replication products aided by HAdV and, in severe cases, HHV-6B may have triggered immune-mediated hepatic disease in genetically and immunologically predisposed children

Potential exploitation of avian resources by fossil hominins: An overview from ethnographic and historical data

Human consumption of bird meat in modern societies comes in two ways: as embryos -i.e., eggs- and as hatched individuals, either young or adults. Poultry provide nowadays about one-third of the animal proteins and fat in human diets, but the bird-human interface is possibly an ancient one. Hundreds of species are kept as pets and non-edible products, such as feathers or eggshells are used by traditional cultures in all continents as body ornaments, headdresses or jewelry. Regarding early humans, it has been proposed that Neanderthals decorated themselves with raptors and corvid feathers. It is also known that they consumed birds, including pigeons, according to cut marks in bone remains. Even if birds may be perceived as elusive prey due to their flight capabilities, they are forced to incubate their eggs in a fixed position, the nest, where the nestlings grow until they reach full size. This makes eggs, nestlings and brooding adults easy prey. Roosting birds are practically defenseless against stealth predators. And humans may become such when they learn to interpret cues left behind by the birds themselves. Birds share a common sensitive world with humans. Most birds are diurnal as we are, and they rely on visual and auditive cues for communication, that we may learn to interpret, or that we can even imitate.Peer reviewe

Undrowning a lost world - The Marine Isotope Stage 3 landscape of Gibraltar

The Rock of Gibraltar, at the south-western extreme of the Iberian Peninsula and 21. km from the North African coast, is a 6-km long limestone peninsula which was inhabited by Neanderthals from MIS 5e until the end of MIS 3. A total of 8 sites, either with Neanderthal fossils or their Mousterian lithic technology, have been discovered on the Rock. Two, Gorham's and Vanguard Caves, are the subject of ongoing research. These caves are currently at sea level, but during MIS 3 faced an emerged coastal shelf with the shoreline as far as 5. km away at times. They hold a unique archive of fauna and flora, in the form of fossils, charcoal and pollen, helping environmental reconstruction of now-submerged shelf landscapes. In addition, geological and geomorphological features - a 300-metre dune complex, elevated aeolian deposits, raised beaches, scree, speleothems - complement the biotic picture.The work is further complemented by a study of the ecology of the species recorded at the site, using present-day observations. The species composition in this fossil record closely matches the present day fauna and vegetation of the Doñana National Park, SW Spain: a mosaic of pine groves, coastal dunes, shrubland and seasonal wetlands and currently the richest reserve in terms of biodiversity in the Iberian Peninsula, located only 100. km to the northwest from Gibraltar.All this information permits, for the first time, the quantification of the vegetation structure of the ancient coastal plain and the modelling of the spatio-temporal dynamics of the MIS 3 coastal shelf off GibraltarPeer reviewe

Following the last Neanderthals: Mammal tracks in Late Pleistocene coastal dunes of Gibraltar (S Iberian Peninsula)

The aeolian Pleistocene deposits recorded in the Rock of Gibraltar (S Iberian Peninsula) present a significant sedimentary thickness that fills the wide sea caves and covers its steep slopes. In Catalan Bay these deposits register the development of cliff-foot and rampant dunes that form a 35° sand ramp, 1 km long and up to 300 m in height formed by moderately to well-sorted sands, slightly carbonated and weakly cemented. This morphosedimentary evidence is associated with MIS 5−2 sea level fluctuations. Its internal structure shows lamination sets of 2–3 m in thickness and planar and trough cross-bedding. In these beds, five morphotypes of mammalian footprints have been recognized in vertical cross sections and convex hyporeliefs. Most of them present a moderate degree of conservation due to the poor cementation of the sands. These icnites are related to the activity of terrestrial mammals, possibly belonging to Homininae, Proboscidea, Artiodactila and Carnivora. The affinity between the footprints and their tracemakers has been established in the basis of their physical parameters, the shape of the footprints, their comparison with similar footprints and the correlation with the fossil fauna of vertebrates described for the Late Pleistocene in Gibraltar. These findings represent the first palaeoichnological record in the aeolian sediments of Gibraltar and indirectly corroborate the occupation of the coastal dune landscape by several terrestrial mammals during the Late Pleistocene. In addition, they help reconstructing the animal behaviour and interaction with the extensive dune systems that developed at the foot of the Rock slopes. The age of the tracks has been established within the MIS 2, during the probable Middle-Upper Palaeolithic transition in the climate refuge of Gibraltar.Research supported by the Spanish MICINN-FEDER Project CGL2010-15810/BTE, This study is part of the activities of the Research Group RNM 293 “Geomorfología Ambiental y Recursos Hídricos”, University of Huelva.

Climate forcing and Neanderthal extinction in Southern Iberia: insights from a multiproxy marine record.

6 figures, 1 tablePaleoclimate records from the western Mediterranean have been used to further understand the role of climatic changes in the replacement of archaic human populations inhabiting South Iberia. Marine sediments from the Balearic basin (ODP Site 975) was analysed at high resolution to obtain both geochemical and mineralogical data. These data were compared with climate records from nearby areas. Baexcces was used to characterize marine productivity and then related to climatic variability. Since variations in productivity were the consequence of climatic oscillations, climate/productivity events have been established. Sedimentary regime, primary marine productivity and oxygen conditions at the time of population replacement were reconstructed by means of a multiproxy approach. Climatic/oceanographic variations correlate well with Homo spatial and occupational patterns in Southern Iberia. It was found that low ventilation (U/Th), high river supply (Mg/Al), low aridity (Zr/Al) and low values of Baexcess coefficient of variation, may be linked with Neanderthal hospitable conditions. We attempt to support recent findings which claim that Neanderthals populations continued to inhabit southern Iberia between 30 and 28 ky cal BP and that this persistence was due to the specific characteristics of South Iberian climatic refugia. Comparisons of our data with other marine and continental records appear to indicate that conditions in South Iberia were highly inhospitable at 24 ky cal BP. Thus, it is proposed that the final disappearance of Neanderthals in this region could be linked with these extreme conditions.This work was financed by Projects REN2003-09130-CO2-01 and CGL2006-13327-C04-04 (MEC), project RNM 432 and Research Group RNM 179 (Junta de Andalucía).
