The Iberian Peninsula is one of the key areas for studying the last populations of Neanderthals and the arrival in Europe of the first anatomically modern humans. In the Cantabrian region, this process can be traced in just a few sites with levels dating to the final stages of the Middle Palaeolithic and the earliest phases of the Upper Palaeolithic. One of these singular enclaves is El Cuco rock-shelter, where the sequence was initially dated by 14C only to the early Upper Palaeolithic sensu lato. However, new studies and datings now place this archaeological sequence in the late Mousterian and the Aurignacian. In this article we present a chrono-cultural reassessment of the upper levels of El Cuco (III-V), including a study of the large mammals. Levels Vc and Vb (>43.5- 40.5 ky uncal BP) date from the late Mousterian, whereas levels Va, IV and III (c. 36.5-30 ky uncal BP) cover an interval extending at least from the Early Aurignacian to the Evolved Aurignacian. Particularly noteworthy is the discovery in level Va of a set of decorative beads made from marine shells in a context of possible symbolic behaviour. [ABSTRACT FROM AUTHOR]

We studied 36 dogs (Canis familiaris) from the Can Roqueta site in the Catalan pre-littoral depression (Barcelona), dated between the Late Bronze Age and the First Iron Age (1300 and 550 cal BC). We used a sample of 27 specimens to analyse the evolution of the dogs' diet based on the carbon δ13C and nitrogen δ15N isotope composition. The results show a marked human influence in that these natural carnivores display a highly plant-based diet. The offset between canids and herbivorous ungulates does not reach the minimum established for a trophic level, which implies an input of C3 and C4 (millet) cultivated plants. Moreover, the homogeneity in the values indicates that humans prepared their dogs' food. [ABSTRACT FROM AUTHOR]

During the Last Glacial cycle (MIS 4 to MIS 2), the isthmic Pyrenees mountain range acted as a biogeographical barrier, effectively restricting faunal exchanges to its western and eastern terminations. The study of the composition of megaherbivore communities has revealed the transitional character of the Cantabrian region (northwest Iberian Peninsula) during the MIS 3, between western European cold faunas and southern Iberian temperate faunas. In the Catalan area (northeastern Iberian Peninsula), cold‐adapted faunas are frequently recorded during the cold pulses of MIS 3 and MIS 2, albeit to a lesser extent. In the present paper, we provide the first direct evidence of a muskox record in the Iberian Peninsula, together with a morphometric study and the results of collagen δ13C and δ15N analysis. The results reveal that the Arbreda specimen fits biometrically within the Late Holocene Umingmak specimens (Banks Island, Canada). Moreover, its isotopic values fall into the range of Late Pleistocene Mammoth steppe muskoxen, which indicates a typical ecological behaviour for muskox. Indeed, it suggests a niche partitioning of this cold‐adapted specimen in relation to other Gravettian Iberian fauna. Chronologically, this occurrence is interpreted as an isolated southward expansion of the biogeographical limits of muskox during the Greenland Stadial 4, in the latest MIS 3. [ABSTRACT FROM AUTHOR]

Abstract: Mollet Cave is a small cave situated in Serinyà (north-east Iberian Peninsula). It was excavated in 1947–48, 1958 and 1972 by Josep M. Corominas. An archaic human molar comes from its base layer (Layer 5). Up till now, this layer has only been dated based on a relative and imprecise chronology of macromammals and the archaeostratigraphic evidence from the early excavations. Recent excavations, conducted between 2001 and 2005, have made it possible to ascertain more precisely the archaeological and palaeontological contents of Mollet Cave, gather microvertebrates, and collect samples for radiometric dating. The aim of this paper is to present the absolute dating of Layer 5, as well as its palaeo environmental and climatic characterisation. The macromammal assemblage seems to have been the result of accumulations produced by the most abundant carnivore, the hyena, which would have used the cave as a den. The results obtained using uranium-series disequilibrium dating ascribe to Layer 5 an age of ca. 215 ka (thousands of years ago), which would correspond to MIS 7. The faunal association suggests a landscape formed by an open and humid woodland characteristic of an interstadial phase, which would have been an environment well suited to sustaining both hyenas and human groups.

Abstract: The Iberian Peninsula plays a central role in the current debates on the Middle-Upper Palaeolithic transition and the Neanderthal extinction. This is largely due to the chronological data which some authors have suggested show a clear divide between Northern Iberia, where the Upper Palaeolithic appeared as early as 36.5 ka 14C BP, and Southern Iberia, where the Middle Palaeolithic survived until ca. 32–30 ka 14C BP or later. The best example of this view is the Ebro Frontier hypothesis. However, there are chronological data in both Northern and Southern Iberia that do not fit this pattern, and some of the evidence supporting the Ebro Frontier hypothesis has been questioned in recent years. This paper focuses on the chronology of the final Middle Palaeolithic of Northern Iberia, where several assemblages have been found to post-date the first Upper Palaeolithic in the region, and be of a similar age to the final Neanderthal occupations of the south. In order to improve the chronological framework of the Middle-Upper Palaeolithic boundary in the Northern Iberian Peninsula, a radiocarbon dating program is focused on sites from both the Cantabrian and Mediterranean regions. The first results of this program are presented in this paper. New radiocarbon dates have been measured by two laboratories using a range of pre-treatment methodologies. These do not support a late Middle Palaeolithic in Northern Iberia. [Copyright &y& Elsevier]

The aim of this study is to understand the feeding habits of the cave bear, Ursus spelaeus by investigating the dental microwear patterns of 106 molars from six Late Pleistocene caves in Catalonia (Spain): Ermitons Cave, Arbreda Cave, Mollet Cave, Llenes Cave, Toll Cave, and Teixoneres Cave. Dental microwear patterns of U. spelaeus were compared with a reference collection of extant ursid species. The results show an omnivorous and carnivorous diet in all sites analyzed with both intra- and inter-site pattern variability. Unlike previous studies, here dental microwear identified more carnivorous habits for the herbivorous cave bear during the days/weeks before death. More varied and higher energy items would help to cope with the hibernation period. The variability between the samples could be due to the characteristic climatic shifts of the Late Pleistocene and to the corresponding differences in the availability of resources.

Abstract: Marine Isotope Stage 7 (MIS 7) is an interglacial that has not been a major topic of scientific interest, yet is interesting because it contains five warm and cold phases (MIS 7e-a) within a brief period of time (ca. 246–186 ka). In this context, there are several sites that contain Middle Pleistocene human remains in Europe, including Mollet cave, the subject of this study. Analyses of the small vertebrates from this cave, together with the numerical dating (ca. 215 ka), established the environmental and climatic conditions in which the hominins who frequented the cave lived. The results obtained situate the Middle Pleistocene hominins of Mollet cave in the MIS 7c substage, indicating that the occupation by humans took place in a transitional phase from a warm to a cold stage with forest development.
