A catalogue of the vertebrate fossil record from the Guadix-Baza Basin (SE Spain)
2020
In this paper, a catalogue of the vertebrate content of the Guadix-Baza Basin is presented. A total of 93 localities have been reviewed, providing more than 300 vertebrate species. These localities have been included in 11 biochronological units, ranging in age from the late Miocene (MN 13) to the Middle Pleistocene (MmQ 4), including also two MN 10 localities. The best-represented epoch in the Guadix-Baza Basin is the Pliocene (MN 14 to MN 16), with 41 sites. This is followed by the Early Pleistocene (MN17 and MmQ1 to MmQ3) with 30 sites. The vertebrate classes represented in the basin are Actinopterygii, Amphibia, Aves, Reptilia and Mammalia, this last one being the best represented. Amon…
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…
Phylogeny and biogeography of fossil and extant Microtus (Terricola) (Mammalia, Rodentia) of Sicily and the southern Italian peninsula based on curre…
2011
Abstract The fossil record of the Savi vole, Microtus ( Terricola ) savii , is analyzed in terms of morphological and morphometrical variability of the first lower molar, in order to reconstruct phylogenetic relationships between insular and mainland populations and the dispersal events. The present work gives a contribution to better understand the phylogenetic history of this taxon in Sicily and Southern Italy during the interval Middle Pleistocene – Holocene, in an attempt to reconstruct the relationships between insular and continental voles and to clarify some paleobiogeographical aspects. The morphometrical data have been acquired by traditional measurements of the first lower molar a…
Effects of glaciation on karst hydrology and sedimentology during the Last Glacial Cycle: The case of Granito cave, Central Pyrenees (Spain)
2021
In Alpine regions, speleothem development on karst systems largely occurs during warm interglacial or interstadial phases due to their limited growth during cold stages. Still, recent attention has been given to the role of clastic sediments in caves, less dependent on temperature conditions. Yet, only a small number of caves worldwide preserve both speleothems and detrital deposits. Here we present an outstanding record of fine-grain laminated sediments and carbonate speleothems from the Granito cave (South Central Pyrenees, Spain) associated with seasonal to annual hydroclimatic pulses through the Last Glacial Cycle (LGC). Analysis of cave clastic facies together with new absolute dates o…
The rodents of the Pirro Nord fauna (Foggia, Southern Italy)
2013
The rodent fauna of various fissure fillings of the Pirro Nord karstic complex are examined here. They have been collected during several field caingns starting from the 70’s until 2006 and are here examined in a comprehensive matter. Hundreds of specimens of arvicolids, murids and, in much lower amount, Glirids have been recovered from several of these fissures. They belong to the species Allophaiomys ex gr. ruffoi, Myodes sp. Apodemus flavicollis and Muscardinus sp.

After the emergence of the Acheulean at Melka Kunture (Upper Awash, Ethiopia): From Gombore IB (1.6 Ma) to Gombore Iγ (1.4 Ma), Gombore Iδ (1.3 Ma) a…
2021
International audience; While the emergence of the Acheulean is well documented in East Africa at ~1.7 Ma, subsequent developments are less well understood and to some extent controversial. Here, we provide robust evidence regarding the time period between 1.6 Ma and 1.2 Ma, based on an interdisciplinary approach to the stratigraphic sequences exposed in the Gombore gully of Melka Kunture, in the upper Awash Valley of Ethiopia. Throughout the Pleistocene, the environment differed significantly from elsewhere in Africa because of the elevation at 2000 m asl, the cooler and rainy climate, the Afromontane vegetation, the development of endemic animal species, and the recurrent impact of volcan…

Capra alba Moyà-Solà, 1987 del Pleistoceno Inferior de la Sierra de Quibas (Albanilla, Murcia, España)
2006
The first palaeontological study of the locality of Quibas dates from the end of the 1990s (Montoya et al., 1999), describing over 60 vertebrate taxa. One of these was a caprine assigned to Capra sp. aff. Capra alba. Recent excavations yielded new remains of this taxon, which permits a more profound study of its affinities and an assignation to Capra alba, without reservation. This assignation is based on the morphological and metrical comparison of the skulls, horn cores, dentition and metapodials from Quibas with those of Capra alba from Venta Micena (Orce Granada).
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…
