Coping with arid environments: A critical threshold for human expansion in Europe at the Marine Isotope Stage 12/11 transition? The case of the Iberi…
2020
Abstract Archaeological remains have highlighted the fact that the interglacial Marine Isotope Stage (MIS) 11 was a threshold from the perspective of hominin evolution in Europe. After the MIS 12 glaciation, considered one of the major climate-driven crises experienced by hominins, the archaeological records show an increasing number of occupations, evidence of new subsistence behaviors, and significant technical innovations. Here, we used statistical and geographic techniques to analyze the amphibian- and reptile-based paleoclimate and habitat reconstructions generated from a large data set of the Iberian Peninsula to (1) investigate if temperature, precipitation, and/or forest cover may h…
Latest Villafranchian climate and landscape reconstructions at Pirro Nord (southern Italy)
2019
Abstract Early Pleistocene terrestrial climate conditions in the Mediterranean region, especially between 1.3 and 1.7 Ma, are poorly understood. Here, the amphibian and reptile fossil record from 24 fissures (Cava Pirro) of the Pirro Nord karstic complex (southern Italy) is used to infer quantitative paleoclimatic and paleoenvironmental reconstructions. These numerical data indicate that the mean annual temperature may have been somewhat lower (–1.6 to –3.6 °C compared to modern temperatures) than that of today, and the mean annual precipitation slightly higher (+90 to +240 mm) than modern values. Seasonality was more pronounced, with cooler summers (–0.4 to –2.0 °C) and much colder winters…
Early Pliocene continental vertebrate fauna at Puerto de la Cadena (SE Spain) and its bearing on the marine-continental correlation of the Late Neoge…
2017
In this paper, we synthesize sedimentological, magnetostratigraphic and paleontological data from the continental vertebrate site of Puerto de la Cadena (Murcia, SE Spain), in order to clarify its age. The study site is located on the northern edge of the Carrascoy mountain range, in the upper part of the Cigarrón Unit. The end-Messinian discontinuity has been detected at the base of this unit, which indicates it has an early Pliocene age. Abundant remains of small and large vertebrates, including rodents, lagomorphs, primates, carnivorans, perissodactyls, artiodactyls, proboscideans, testudines, squamats, and crocodiles, have been found in this area. Some of these elements are of African o…
New data on Sicilian prehistoric and historic evolution in a mountain context, Vallone Inferno (Scillato, Italy)
2013
Vallone Inferno rock-shelter is an archaeological site located in the Madonie mountain range in Sicily. Archaeological excavation and research have provided a long prehistoric and historic sequence from the Neolithic to the medieval period, this being the most complete work in this area at present. In this paper we present the preliminary data provided by a multidisciplinary study based on pottery, lithic, human, faunal and plant remains. Stratigraphic studies have identified four complexes, of which complex 3 has provided almost all the archaeological remains. 14C AMS dates, obtained from four samples, place the human activities between 2601 cal BC and 644 cal AD. These dates are coherent …
Palaeoecological implications of Neanderthal occupation at Unit Xb of El Salt (Alcoi, eastern Spain) during MIS 3 using small mammals proxy
2018
Nearly 250 small mammal remains from Unit Xb of El Salt Middle Palaeolithic site have been studied in order to reconstruct the palaeoecological conditions during a phase of Neanderthal occupation in this locality at 52.3 ± 4.6 ka. A total of 7rodents (Microtus arvalis, M. agrestis, M. (Terricola) duodecimcostatus, Microtus (Iberomys) cabrerae, Arvicola sapidus, Eliomys quercinus and Apodemus sylvaticus), 4 insectivores (Erinaceus cf. europaeus, Crocidura sp., Sorex sp. and Talpidae indet.) and 1 lagomorph (Oryctolagus cf. cuniculus) have been identified. Applying the Mutual Ecogeographic Range and Habitat Weighting methods, Unit Xb may correspond to a relatively cold (−3.3 °C in comparison …
Trade and stowaways: molecular evidence for human-mediated translocation of eastern skinks into the western Mediterranean: supplementary material
2019
Human movements in the regions surrounding the Mediterranean Sea have caused a great impact in the composition of terrestrial fauna due to the introductions of several allochthonous species, intentionally or not. Reptiles are one of the groups where this anthropic impact is most evident, owing to the extensive intra-Mediterranean dispersals of recent chronologies. Chalcides ocellatus is a widespread skink with a natural distribution that covers almost the entire Mediterranean Basin. Two hypotheses have been proposed to explain its origin: natural dispersions and human translocations. Previous molecular data suggest the occurrence of a recent dispersal phenomenon across the Mediterranean Sea…
Improving the accuracy of small vertebrate-based palaeoclimatic reconstructions derived from the Mutual Ecogeographic Range. A case study using geogr…
2019
Abstract Understanding past climate and the mechanisms of climate change remain major challenges in scientific research. The Mutual Ecogeographic Range (MER) method for climatic reconstruction uses the current geographical distribution of fossil assemblages to infer palaeoclimatic conditions. Current species distributions used in the MER method are usually obtained from biogeographic atlases that record the absence/presence of species in a 10 × 10 km grid. A 10 × 10 km area is quite broad and the method only records presence/absence, without considering the real area occupied by any given species. Thus, the method overlooks the fact that environmental heterogeneity is strongly related to to…

Applying the UDA‑ODA discrimination technique to a herpetological association: the case of the Middle Palaeolithic site of El Salt (Alcoi, Spain)
2022
AbstractEl Salt (Middle Palaeolithic; Alcoi, Spain) is a key site for understanding the disappearance of Neanderthals in the eastern Iberian Peninsula, a process that is observed along its stratigraphic sequence. To improve our understanding of the palaeoclimatic context in which this process took place, we applied the UDA-ODA discrimination technique to the fossil herpetological assemblages from Stratigraphic Units (SU) Xb (52.3 ± 4.6 ka) and V (45.2 ± 3.4/44.7 ± 3.4 ka). This method is based in the application of an ecological criterion, the maximum altitude of each species on each Iberian range, to discern and remove those areas that do not meet their ecological requirements (UDA) from t…
