Bulletin de la Société Géologique de France, 2007 Abstract This paper discusses ostracods and their environmental setting close to the Givetian/Frasnian boundary in the Puech de la Suque Global Stratotype Section and Point. The ostracod fauna belongs exclusively to the Eifelian mega-assemblage and is largely dominated by Podocopina instars.

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract We estimate the cosmic dust flux to Earth through the study of rare micrometeorites that preserve part of their precursor features during atmospheric entry heating, namely unmelted and scoriaceous subtypes. Combining high‐precision mass balance measurements, X‐ray computed microtomography and scanning electron microscopy, we studied mass, size

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.Abstract The Paleocene–Eocene Thermal Maximum (PETM; ∼55.9 Ma) was a rapid global warming event marked by intensified hydrological cycling, enhanced continental weathering, and widespread ocean deoxygenation. Although the extent of anoxic basins during the PETM is relatively well documented, the contribution of high‐latitude continental weathering to ...

Carboniferous basement rocks of northern Britain [PDF]
, 1987 The study of Carboniferous basement rocks of northern Britain has concentrated on the dominantly clastic rock succession which unconformably overlies the Lower Palaeozoic basement and occurs beneath the lowermost Carboniferous limestones in areas ...

Non‐Uniqueness, Symmetries and Invariance of Thermal History Modelling in Sedimentary Basins
Basin Research, Volume 38, Issue 4, July–August 2026.This paper approaches non‐unique inverse problems by generating a representative ensemble of all possible solutions using the concept of symmetry. In the context of basin modelling, a symmetry is any manipulation of a forward model's parameters (e.g., thermal history) that leaves the model output (e.g., downhole vitrinite reflectance) unchanged ...

New record of a Middle Devonian brachiopod fauna from the Northern Arabian Plate, Zap Anticline, Cukurca-Hakkari, Southeastern Turkey [PDF]
, 2012 International audienceBrachiopods recently collected from the Zap River Valley area (SE Turkey) allow to establish a Middle Devonian (upper Givetian) age for the upper middle part of the Yiginli Formation which was until now considered as Famennian on ...

Journal of Anatomy, Volume 249, Issue 1, Page 127-140, July 2026.Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.
