Facies distribution and depositional cycles in lacustrine and palustrine carbonates: The Lutetian–Aquitanian record in t...

The difficulty of correlating continental deposits hinders predicting lacustrine and palustrine carbonate facies variations in time and space. This study aims to understand better the factors governing these facies heterogeneities by measuring carbonate isotopes and conducting facies, petrographic and sequence stratigraphic analyses of the Lutetian...

First fossil woods and palm stems from the mid Paleocene of Myanmar and their implications for biogeography and wood ana...

Premise: The rise of angiosperm‐dominated tropical rainforests has been proposed to have occurred shortly after the Cretaceous‐Paleogene transition. Paleocene fossil wood assemblages are rare yet provide important data for understanding these forests and whether their wood anatomical features can allow us to document these changes. Method: The anat...

First flower inclusion and fossil evidence of Cryptocarya (Laurales, Lauraceae) from Miocene amber of Zhangpu (China)

Lauraceae have one of the oldest fossil records of angiosperms with the earliest known evidence from the mid-Cretaceous. However, most of these records are based on leaves, especially from the Cenozoic of Asia, which are often challenging to assign to extinct or extant genera or species. In contrast, fossils of reproductive organs are more informat...

The PaleoJump database for abrupt transitions in past climates

Published in Scientific Reports

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...

Correlation of the Marsawdad Formation, Oman, Late Miocene (Turolian-Ventian), based on fossil avian eggshells

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 Cenozoic terrestrial deposits of the Arabian Peninsula

Caractérisation des hétérogénéités réservoirs dans les carbonates continentaux du Cénozoïque du bassin de Paris : Liens ...

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 ...

Fruits of Anacardiaceae from the Paleogene of the Paris Basin, France

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. ...
