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 presentes en el interior de la misma y que informan del uso del Hayal de Guinea como espacio funerario durante la Protohistoria. Por su parte, el grueso del material paleontológico recuperado procede de un depósito situado en la sala terminal de la cavidad. En este espacio se llevó a cabo una recogida sistemática del material en superficie, fruto de intervenciones incontroladas, así como un sondeo estratigráfico que resultó rico en evidencias paleontológicas.

Quaternary tufas of the Inglares River valley: An example of changing slope stepped fluvial system, Álava, N Spain
This study examines the factors that controlled the formation of Quaternary calcareous tufa deposits along the valley of the Inglares River (Álava, north Spain), currently fed by a karst-carbonate aquifer. It is based on stratigraphic, chronological (Amino Acid Racemisation, AAR), sedimentological, and δ13C and δ18O analyses, complemented by palaeontology (molluscs, ostracods and charophytes). The examined deposits occur as isolated bodies in the uppermost and downmost stretches of the valley, reaching 45 and 25m in thickness, respectively. AAR dating classified them into two groups: Middle Late Pleistocene (MIS 5e) and Middle and Late Holocene (MIS 1). The former only occurred in the downstream stretch. Up to eleven carbonate facies and minor allochthonous coarse detrital facies have been characterised and arranged into four distinct facies associations. Their features and bedding geometries suggested two main depositional settings: a low- to moderate-slope stepped stretch with small barrage cascades, dammed areas, and abundant palustrine zones (downstream system) and a high-slope stretch with steep stepped cascades and pools (upstream system). These settings respond to bedrock lithology and structural changes throughout the valley, which appear to be the principal factors controlling the tufa depositional architecture. Based on δ13C, an increase in aridity was inferred from the Middle–Late Pleistocene to Holocene. The isotopic differences between the upstream and downstream Holocene tufa might reflect the spatial evolution of δ13C and δ18O in stream water through the approximately 8km long surveyed transect. Erosion due to sudden changes in water discharge may have caused the stratigraphic gap between the two tufa groups.

Revised age for Schöningen hunting spears indicates intensification of Neanderthal cooperative behavior around 200,000 years ago
The Schöningen 13II-4 archaeological site in Germany holds title to the most complete Paleolithic wooden hunting spears ever discovered, yet its age has never been properly settled. Initial estimates placed the site at around 400,000 years; this age was later revised to roughly 300,000 years. Here, we report age estimates for the “Spear Horizon” based on amino acid geochronology of fossils obtained directly from the find-bearing deposits. Together with a reassessment of regional Middle Pleistocene chronostratigraphy, these data place the Schöningen spears at ~200,000 years. This revised age positions the Spear Horizon alongside other sites that collectively record a shift toward communal hunting strategies. The Schöningen archaeological record exemplifies this behavioral transformation that arose within the increasingly complex social environments of Middle Paleolithic Neanderthals.

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 Pleistoceno superior.

Análisis de los restos de cánido del Pleistoceno medio de la Torca de la Dehesa (Ondategi, Álava-Araba)
En este trabajo se presenta el estudio realizado en torno a los restos de cánido descubierto de manera casual en la Torca de la Dehesa (Ondategi, Álava-Araba). Durante este estudio se ha procedido a datar y estudiar un conjunto de 61 restos craneales y postcraneales pertenecientes a un solo individuo. Las dataciones obtenidas sitúan los restos en el MIS 6; el análisis biométrico y morfológico han permitido clasificar los restos como pertenecientes a un ejemplar de Canis lupus Linnaeus, 1758. El estudio biogeográfico ha permitido contextualizar a nivel regional este hallazgo.
