The discovery of fossilised struthious eggshell fragments on outcrops of the Marsawdad Formation, Rub’ Al-Khali, Oman, permits estimation of the age of the deposits, indicating correlation to the Late Miocene (Turolian-Ventian: Tortonian-Messinian) ca 8-7 Ma. The eggshells are described and are located within a revised biostratigraphy of the Cenozo...
L'intérêt porté aux carbonates continentaux n'a cessé de croitre ces dernières années pour leur usage comme réservoir géologique (géothermie, eau, stockage), comme matériaux (pierre de construction) ou pour la géotechnique, notamment dans la métropole du Grand Paris. Cependant, ces carbonates sont très hétérogènes, causant des variations spatiales ...
Premise of research. The Anacardiaceae family is distributed throughout the vegetated continents. The fossil record indicates extensive diversification of the family during the Paleogene and, in particular, during the Eocene. Despite the abundant fossil record of this period, there are only a few reliable anacardiaceous fossils in the Paris Basin. ...
Tipping points (TPs) in Earth's climate system have been the subject of increasing interest and concern in recent years, given the risk that anthropogenic forcing could cause abrupt, potentially irreversible, climate transitions. Paleoclimate records are essential for identifying past TPs and for gaining a thorough understanding of the underlying n...

The Tarim Basin is the largest sedimentary basin in China, and it has experienced a complex tectonic evolutionary history. Reconstruction of the proto-type basin and tectono-paleogeography is helpful to understand the different stages of evolution of the sedimentary basin and basin-mountain relationship. It is significant to combine the basin with ...
Oligomonoctenus neytiriae gen. et sp. nov., the second fossil representative of the family Diprionidae from the uppermost Oligocene of Aix-en-Provence, France, is described on the basis of a well-preserved compression fossil. It is compared to the other extant and fossil diprionid genera. Its morphology and wing venation support placement in the su...
The Tibetan Plateau geographically contains internal and external drainage areas based on the distributions of river flows and catchments. The internal and external drainage areas display similar high elevations, while their topographic reliefs are not comparable; the former shows a large low-relief surface, whereas the latter is characterized by r...
The palaeobotanical record of Myanmar (Burma) is poorly documented despite its importance for understanding the evolution of Asian monsoonal ecosystems through time. Here, we describe 20 taxa of fossil wood from 30 silicified specimens collected in the upper lower to lowermost middle Miocene Natma Formation, central Myanmar. These fossils share aff...

The triple oxygen isotope composition (Δ'17O) of sulfate minerals is widely used to constrain ancient atmospheric pO2/pCO2 and rates of gross primary production. The utility of this tool is based on a model that sulfate oxygen carries an isotope fingerprint of tropospheric O2 incorporated through oxidative weathering of reduced sulfur minerals, par...
Elasmobranchii are relatively well-studied. However, numerous phylogenetic uncertainties about their relationships remain. Here, we revisit the phylogenetic evidence based on a detailed morphological re-evaluation of all the major extant batomorph clades (skates and rays), including several holomorphic fossil taxa from the Palaeozoic, Mesozoic and ...
