Hayal de Guinea (Guinea). Un nuevo yacimiento arqueo-paleontológico en Araba/Álava
La cueva del Hayal de Guinea (Guinea, Araba/Álava), es una cavidad que ha sufrido diversas actuaciones clandestinas. Los trabajos realizados entre 2019-2022 documentaron diversas zonas intactas, en las que recuperamos material arqueológico y paleontológico que presentamos por primera vez en este artículo. La presencia humana fue efímera, probablemente adscrita a cronologías históricas en la entrada de la cavidad, junto a restos antropológicos pre…

La cueva de Oilaskoa (Saint Michel / Eiheralarre, Baja Navarra, Francia), puesta en valor de un conjunto de Ursus spelaeus Rosenmüller (1794) en el Pirineo Occidental
En este trabajo se presentan los resultados del estudio de un conjunto paleontológico recuperado en la cueva de Oilaskoa entre 1981 y 1986. La ubicación de esta cueva en el extremo occidental del Pirineo, a 1036 metros de altitud y su aislamiento con respecto a otras acumulaciones del mismo tipo, hacen de este conjunto una oportunidad única para conocer la población de Ursus spelaeus Rosenmüller que pobló el occidente del Pirineo durante el Pleis…
Lipid biomarkers in high mountain lakes from the Cantabrian range (Northern Spain)
The lipid content of a high mountain lake (Lake Isoba) allowed the reconstruction of the paleoenvironmental changes and anthropic influence in Northern Spain during the last 550 years. Fatty acids (FAs) and n-alkan-2-ones indicate little degradation of OM. Three units were delimited. During Unit A (ca. 1460-1780 CE) high carbon preference index values, predominance of high-molecular-weight saturated FAs, and good correspondence between the predom…
Development of the marine Holocene environment in a drowned paleovalley with final anthropic influence in the Cartagena Bay (Murcia, SE Spain)
Sedimentological, paleobiological, mineralogical, and geochemical analyses of a sediment core retrieved on the seafront of Cartagena Bay were performed after high-resolution sampling. A wide series of dates obtained through radiocarbon and amino acid racemization proved that the Holocene record on the analyzed core began at ca. 7300 yr cal BP. Reinterpretation of the marine seismic profiles indicated that the beginning of this transgression was c…
An Approach to a Punic Harbour Area in Cartagena (Southeast of Spain)
The Greek-Latin authors present Qarthadašt (Cartagena) as one of the main bastions of territorial control of the Carthaginians in Iberia. It had easy and close maritime relationship with Africa, the Strait area and Ibiza, and was located near rich silver deposits. These two reasons are determining factors in its prosperity. The geomorphological evolution and a history without interruption have notably changed the original physiognomy of the site,…
El Niño Cave (Aýna, Albacete, Spain)
El Niño cave, located on the south-eastern border of the Spanish Meseta, hosts a discontinuous sequence including Middle Palaeolithic and Neolithic levels, along with Upper Palaeolithic and Levantine style paintings. It is a key site for understanding human occupations of inland Iberia during the Palaeolithic and early prehistory. This paper summarises the main results of a multidisciplinary project aimed at defining the prehistoric human occupat…
The Pleistocene and Holocene records of the Mazarrón Basin (SE Spain)
Development of Quaternary travertines in the carbonate mountains of the western Costa del Sol, Málaga, southern Spain
The predominantly carbonate nature of the mountains near the coast of Málaga and Marbella (Costa del Sol, southern Spain) and the presence of springs have favored the formation of travertine buildups during the Quaternary. The geomorphic characteristics of the slopes and the location of the springs have determined the development of three types of travertine growths: (1) spring travertines, located preferentially on the south mountainside, where …
Reconstructing human–landscape interactions in the ancient Mediterranean harbour of Cartagena (Spain)
Here, we sought to reconstruct the Pleistocene and Holocene evolution of Cartagena Bay. Therefore, 16 borehole cores were analysed with the following aims: (1) to define a chronological framework; (2) to obtain data on the palaeoenvironment; and (3) to establish the relationship with human activities, especially focused on the reconstruction of the Carthago Nova (also known as Qart Hadasht) conquest. A total of 147 samples were recovered for amin…
Evidence for Holocene sea level and climate change from Almenara marsh (western Mediterranean)
In the Almenara marsh (western Mediterranean), four cores were analyzed to establish the relationship between the marsh record of the Almenara marshlands and the environmental factors responsible for its evolution during the Holocene. One hundred and eighty-six samples were collected for sedimentologic and paleontological study: 63 for biomarker analysis; 5 for amino acid racemization (AAR) dating; and 5 for 14 C dating. Litho and biofacies analy…

Climatic implications of the Quaternary fluvial tufa record in the NE Iberian Peninsula over the last 500 ka
The drainage area of the Iberian Ranges (NE Spain) houses one of the most extensive Quaternary fluvial tufaceous records in Europe. In this study, tufa deposits in the Añamaza, Mesa, Piedra and Ebrón river valleys were mapped, stratigraphically described and chronologically referenced from U/Th disequilibrium series, amino acid racemization and radiocarbon methods. Tufa deposits accumulated in cascades, barrage-cascades and related damming areas …

Two middle Pleistocene warm stages in the terrace deposits of the Apulia region (southern Italy)
La ocupación de la costa durante el Mesolítico en el Oriente de Asturias
The discovery of Paracentrotus lividus remains in archaeological sites is an important source of information that is not always possible to assess due to the difficulty of quantifying the debris and its contribution to the overall study. Recently, several authors have designed systems for the MNI calculation based on the mouthparts of the sea urchin or interspecific identification systems based on the genital tract. This paper presents an MNI cal…

The Middle Paleolithic site of Cuesta de la Bajada (Teruel, Spain)
A New Date for the Neanderthals From El Sidrón Cave (Asturias, Northern Spain)
Torres et al . (2010 ) published a series of radiocarbon, AAR, ESR and OSL dates from the site of El Sidrón, northern Spain, which is notable for the discovery of the partial remains of 12 Neanderthals. Whilst the non‐radiocarbon methods suggested an age beyond 32 600–46 300 years, direct radiocarbon dates on the human fossils were inconsistent, ranging between 10 000 and 50 000 bp . This study uses the ultrafiltration pre‐treatment protocol to o…

Dating of the Hominid ( Homo Neanderthalensis ) Remains Accumulation From El Sidrón Cave (Piloña, Asturias, North Spain)
The age of Neanderthal remains and associated sediments from El Sidrón cave has been obtained through different dating methods ( 14 CAMS, U/TH, OSL, ESR and AAR) and samples (charcoal debris, bone, tooth dentine, stalagmitic flowstone, carbonate‐rich sediments, sedimentary quartz grains, tooth enamel and land snail shells). Detrital Th contamination rendered Th/U dating analyses of flowstone unreliable. Recent 14 C contamination produced spurious…
The Aminochronology of Man‐induced Shell Middens in Caves in Northern Spain
Here, we provide the first report on the ages of 54 archaeological levels in 38 caves in northern Spain by means of the aspartic acid d / l ratio measurements in Patella shells, with good results. For this purpose, we developed an age calculation algorithm that allows the numerical dating of deposits from other archaeological localities in the area and nearby regions. We conclude that the sample size—that is, the number of shells analysed within …

Bear dentine aspartic acid racemization analysis
A high correlation between chronometric determinations based on aspartic acid racemization ratios and radioactive dating methods is described from samples of cave bear (Ursus deningeri and Ursus spelaeus) dentine. For samples from a very restrictive environment, as deep cave bear sites are (in view of their highly stable geochemical and thermal history), an age calculation algorithm was obtained. It has been found that there is a very close relat…

Paleobiology and comparative morphology of a late Neandertal sample from El Sidrón, Asturias, Spain
Fossil evidence from the Iberian Peninsula is essential for understanding Neandertal evolution and history. Since 2000, a new sample ≈43,000 years old has been systematically recovered at the El Sidrón cave site (Asturias, Spain). Human remains almost exclusively compose the bone assemblage. All of the skeletal parts are preserved, and there is a moderate occurrence of Middle Paleolithic stone tools. A minimum number of eight individuals are repr…
