Neandertal spatial patterns and occupation dynamics: a regional focus on the central region in Mediterranean Iberia
2020
En el siguiente trabajo se estudian varios conjuntos pertenecientes al Paleolítico medio procedentes del mediterráneo peninsular ibérico con el objetivo de examinar los patrones de ocupación y las estrategias de gestión del territorio. Se presta especial atención al abastecimiento de las materias primas y los comportamientos tecnológicos, los datos procedentes de la fauna y los análisis microespaciales. La variabilidad en los tipos de ocupación de los distintos conjuntos nos muestra una gran diversidad y una multitud de factores, aunque no parece tener una sola explicación cultural, funcional, temporal o ambiental. Más bien son explicaciones que responden a una amplia variabilidad en los co…
Human settlements in the Mediterranean and the sea level changes from 12 ka to the present
2012
Understanding past sea-level change plays an important role in determining the underlying causes, and also allows the extrapolation of past sea levels to locations and epochs for which there are no instrumental data. A compilation of global sea-level estimates based on deep-sea oxygen isotope ratios at millennial-scale resolution or higher was published since ‘70. These global sea level curves do not take in account isostasy and tectonics. Observed sea level change can be reconstructed from dated fossils, coral reef terraces, speleothems, emerged and forming terraces on coastal areas, archaeological and other markers well connected with sea level. Because of the lack of coral reefs in the M…
A late Biharian small vertebrate fauna from the lacustrine succession of San Lorenzo (Santarcangelo Basin, Basilicata, Italy)

A detailed analysis of the spatial distribution of Schöningen 13II-4 'Spear Horizon' faunal remains
2021
The Middle Pleistocene Schöningen 13II-4 'Spear Horizon' (Germany) is a key site for the study of human evolution, most notably for the discovery of Paleolithic wooden weaponry and evidence for developed hunting strategies. On the other hand, the 'Spear Horizon' offers an excellent opportunity to approach hominin spatial behavior, thanks to the richness of the archeological assemblage, its exceptional preservation, and the vast expanse of the excavated surface. Analyzing how space was used is essential for understanding hominin behavior at this unique open-air site and, from a wider perspective, for approaching how humans adapted to interglacial environments. In this article, we present an …
A new late pleistocene vertebrate faunal complex from Sicily (S. Teodoro Cave, North-Eastern Sicily, Italy)
2001
Previous excavations at the S. Teodoro Cave were carried on mainly in the upper unit, Late Glacial in age, containing late Upper Palaeolithic stone artefacts and no endemic mammals remains belonging to the Castello Faunal complex, the youngest of the Pleistocene Sicilian faunal complexes. This unit overlies an older deposit of clay and sands which contain Pleistocene endemic mammal remains. During 1998 excavations a maximum depth of m 1.50 over an area of about 12 sq. m has been exploited. Scarce evidences of the Late Glacial have been encountered during excavations. The investigated lower unit (unit B) is made of clayey sands and gravels containing a highly diversified assemblage of verteb…
Large- and small-mammal distribution patterns and chronostratigraphic boundaries from the Late Pliocene to the Middle Pleistocene of the Italian peni…
2007
Abstract Over the last 50 years the studies on terrestrial mammals of the Italian peninsula have provided a large volume of data and a more detailed knowledge of faunal events during the Late Pliocene and Quaternary. Moreover geological, sedimentological, palynological and magnetostratigraphical investigations on the Pliocene–Pleistocene continental sedimentary basins have yielded the possibility of a detailed calibration of the faunal successions. Thus, palaeontologists have been able to reconstruct faunal sequences and to propose biochronological scales based on large and small mammals, respectively. In the present contribution an integration of the two biochronological scales is proposed…
L’histoire de La Balutie, un gisement oublié, voisin de Lascaux et de Regourdou
2023
Cette contribution a pour objet de retranscrire l’histoire du site paléolithique de La Balutie (Montignac-Lascaux, Dordogne, France). L’histoire de ce site très tôt oublié, n’est ni sensationnelle, ni exceptionnelle, mais s’avère retranscrire l’atmosphère caractérisant les débuts des explorations des gisements préhistoriques de Dordogne. On y retrouve de grands noms de la Préhistoire de Dordogne qui n’ont légué que peu d’écrits sur le site, du mobilier trié (surtout lithique) du Paléolithique moyen et supérieur qui a alimenté de nombreuses collections privées avant d’être dispersé au sein de diverses institutions, et un contexte local compliqué et agrémenté de conflits. Notre connaissance d…
Orbital variations in planktonic foraminifera assemblages from the Ionian Sea during the Middle Pleistocene Transition
2013
Abstract The Middle Pleistocene Transition (1.2–0.7 Ma) is the most recent re-organization of the global climate system which includes variations in the frequency and amplitude of glacial/interglacial cycles, increased ice sheet volume, sea surface temperature cooling and a significant drop in the CO 2 atmospheric levels. Here we present high-resolution planktonic foraminifera data (mean sampling resolution of about 780 years) from core LC10 recovered in the Ionian Sea (eastern Mediterranean), between 1.2 and 0.9 Ma. Selected taxa, among them G. ruber , T. quinqueloba and G. bulloides , show significant periodicities that can be associated to orbital cycles, mainly precession and obliquity.…

Late Pliocene and Pleistocene small mammal chronology in the Italian peninsula
2007
The abundant documentation of small mammals in the Italian peninsula, collected over recent years, furnishes a detailed biochronological sequence mainly from the Late Pliocene onwards. An updated stratigraphic framework is here presented, based on the European small mammal biozonation. The Early Villanyian is characterized by Mimomys hassiacus, M. stehlini, and, later, poorly documented M. polonicus. The Late Villanyian localities are well characterized with M. pliocaenicus, M. pitymyoides and M. tigliensis. The older part of the Early Biharian is documented by assemblages containing Microtus (Allophaiomys) ex gr. pliocaenicus, M. pusillus, M. cf. ostramosensis and M. tornensis, while the l…
