De nouveaux fossiles d’astérides (pièces inféro- et supéromarginales) ont été découverts au cours de la dernière décennie dans le Cénomanien et le Turonien inférieur de Charente-Maritime (SO France). Ce matériel inédit permet premièrement, de préciser le statut spécifique de taxons imparfaitement identifiés en Charentes, tels que Hadranderaster simplex, Cymbaster dolmeni et Pycinaster humilis, précédemment...
Les études paléolimnologiques s’avèrent particulièrement pertinentes lorsque les espèces trouvées dans les sédiments sont toujours présentes à l’état vivant dans le milieu et que la végétation submergée peut fournir un analogue direct pour l’interprétation. Ainsi, le lac de Tigalmamine représente un cas exceptionnellement favorable, par rapport à la plupart des paléolacs en Afrique du Nord, puisque...
We present the study of rodents and insectivores from the 1995 season of excavation at the early Late Pleistocene site of Bois Roche (Charente, France). The site is a small cave with a low ceiling, used as a den by hyenas. It contains a large herbivore assemblage (mainly bovids and equids) with a smaller representation of medium-size taxa (cervids), many microvertebrates, abundant coprolites and deciduous...
De nouveaux restes de Leptobos (Smertiobos) crassus sont identifiés dans la faune du nouveau site Pléistocène inférieur de Renzidong, province d’Anhui, dans l’Est de la Chine. C’est un Leptobos portant des chevilles osseuses avec une simple courbure et à partie apicale plus élevée au-dessus du crâne que chez les autres espèces du sous-genre. La présente étude montre que la première apparition de Leptobos...
The mammal locality of Antonios is one of the few known early–middle Miocene ones of Greece with large mammals. It is situated in Chalkidiki Peninsula (Macedonia, Greece) and includes both small and large mammals. The study of the carnivores found in Antonios indicates the presence of the following taxa: Proputorius cf. P. sansaniensis, Protictitherium gaillardi, Protictitherium cf. P. crassum, Percrocuta...
The fossil Desmaninae (water-moles) from the Pliocene continental deposits of Tollo de Chiclana (Guadix Basin, Southern Spain) are described. A new species, Archaeodesmana elvirae, is defined from the locality of Tollo de Chiclana-1 (upper Ruscinian). This species is characterized by relatively small canines and premolars (except the P4) and large P4 and molars, besides several morphological features...
Based on calcareous nannofossils and planktonic foraminifera1 biostratigraphic data from flysch sequences, we give evidence for the paleoenvironmental evolution of Gavrovo and Ionian foreland basins (External Hellenides, Etoloakarnania region). Our data suggest that the onset of clastic sedimentation in both foreland basins in the study area is chronostratigraphically placed at Late Eocene (from 36...
This paper presents the first Permian ostracod fauna discovered in Thailand. The ostracods are recovered from the Tak Fa Limestone (Middle Permian) in Phetchabun province, central Thailand. The ostracods belong to eight genera and 15 species. Four species are newly described: Sargentina phetchabunensis nov. sp., Geffenina bungsamphanensis nov. sp., Reviya subsompongensis nov. sp. and Bairdia takfaensis...
