Accelerator C dates for early upper paleolithic (basal Aurignacian) at El Castillo Cave (Spain)

Three fragments of charcoal taken from different parts of the lowermost bed containing Aurignacian artifacts at El Castillo Cave yielded AMS dates of 37·7 (± 1·8) ka bp, 38·5 (± 1·8) ka bp, and 40·0 (± 2·1) ka bp (average 38·7 ± 1·9 ka bp). These dates are almost identical to new AMS dates from l'Arbreda cave in Catalunya on the same cultural horizon (average 38·5 ± 1·0 ka bp) and are significantly older than the earliest dates for Aurignacian industries in the Aquitaine and in other parts of Central and Western Europe.     

Cave sediments,upper pleistocene stratigraphy and mousterian facies in Cantabrian Spain

Archaeological sediments are analysed from karst cave columns in Cantabrian Spain: Cueva Morín, El Pendo, the Castillo cave complex (including La Flecha, Las Chimeneas, La Pasiega, Las Monedas), Hornos de la Peña and Cobalejos. External sediment influx, including loess, is calibrated by an index of cave and slope run-off energy, while other features (slope and roof rubble, chemical precipitates, cryoturbations, fine soil derivatives, and cultural components) are discussed. The key sequences (Morín, El Pendo, Castillo) are each interpreted in local terms and then combined into a regional climatostratigraphy that includes 40 environmental phases within deep-sea isotope stages 2–5. Trends in run-off energy (reflecting slope stability), temperature, and summer-moisture are rarely in phase, indicating complex environmental change. Mid-Pleistocene and older deposits exist but have largely been destroyed, explaining the apparent absence of Acheulian settlement. Mousterian occupation is verified by isotope stage 5b, and two or three Mousterian facies that span 25–50,000 years are coeval in several caves, regardless of the direction of climatic oscillations. This suggests the flexible lithic technology of a single population, maintaining an adaptive steady state despite repeated environmental changes. By contrast, the distinct upper palaeolithic industries each span only a few millennia, but in part overlap temporally within the region between 35,000 and 9500 bp.     

To see or to be seen… is that the question? An evaluation of palaeolithic sites’ visual presence and their role in social organization

Visibility is one of the most common features considered when analyzing site location; visual control of a territory is usually considered to be a desirable characteristic for a prehistoric settlement. However, the role that visibility could have played in the perception of sites, as a significant element of palaeolithic landscapes, has been rarely evaluated. Sites can act not only as settlements but as places for population aggregations, social interactions and symbolic activities; in this context, the relevance presence of a site within the landscape could have been an influencing factor in site location preferences. This paper focuses on the visual presence of a set of sites from Late palaeolithic Cantabria (Northern Iberian Peninsula), and evaluates how the way they were perceived could have been related to their role in the social organization of foraging communities.
