The systematics and paleobiogeographic significance of Sub-Boreal and Boreal ammonites (Aulacostephanidae and Cardioceratidae) from the Upper Jurassic of the Bohemian Massif

Geologica Carpathica, 2014
Upper Jurassic marine deposits are either rarely preserved due to erosion or buried under younger sediments in the Bohemian Massif. However, fossil assemblages from a few successions exposed in northern Bohemia and Saxony and preserved in museum ...

Post‐Eocene 90° CCW Rotation of Sardinia‐South Corsica: Paleomagnetic Evidence From Permian‐Cretaceous Sediments of Nurra (NW Sardinia)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract The paleomagnetism of Miocene calc‐alkaline volcanics and sediments from Sardinia has firmly showed that the Corsica‐Sardinia microplate rotated 50°–60° counterclockwise (CCW) with respect to Europe between 21 and 15 Ma, during its drift from the Provencal margin. However, Permian to Eocene rocks from central‐south Sardinia revealed higher (up

INTEGRATED STRATIGRAPHY (RADIOLARIANS AND CALCAREOUS NANNOFOSSILS) OF THE JURASSIC SILICEOUS SEDIMENTS FROM MONTE KUMETA (WESTERN SICILY, ITALY)

Rivista Italiana di Paleontologia e Stratigrafia, 2004
Integrated analyses of Calcareous Nannofossils and Radiolarians were carried out in the Monte Kumeta (Sicily) to better define the age of the siliceous sediments (Membro Radiolaritico Intermedio = MRI), which results to be early-middle Bathonian to early

The thermo-mechanical behaviour of the Callovo-Oxfordian claystone [PDF]

International Journal of Rock Mechanics and Mining Sciences, 2015
The Callovo-Oxfordian (COx) claystone is considered as a potential host rock in the French concept of high level radioactive waste disposal at great depth. To better understand and to complement existing published data on the thermo-hydro-mechanical behaviour of the COx claystone, an experimental program was carried out by using a hollow cylinder ...

Evolving late Triassic–Jurassic environments of western Europe: the Schwäbisch Gmünd geological path in southwest Germany compared to the ‘Jurassic Coast’ of Dorset, southern England

Geology Today, Volume 42, Issue 3, Page 134-146, May/June 2026.
The geology of southwest Germany is dominated by continental to marine sedimentary rocks deposited within Mesozoic sedimentary basins which have yielded economic hydrocarbon deposits. This stratigraphy has formed the focus of geological and stratigraphical research for centuries, with world‐famous exposures becoming type sections and lending their name

Dinoflagellate cysts from the Oxfordian (Upper Jurassic) of Skye, Scotland and Southern Dorset, England

, 1991
. Ten sediment samples from Upper Oxfordian strata of Skye and six from the uppermost Lower Oxfordian of southern Dorset were processed for palynomorphs. Of the dinoflagellate cysts recognized, the genus Furzidinium and species F.

New Zealand Geological Timescale 2025

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...

The early origin of Iguanodontia: new insights into the macroevolution, diversity and biogeography of the clade

Palaeontology, Volume 69, Issue 2, 2026.
Abstract Iguanodontia (Dinosauria, Ornithischia) is a speciose group of herbivorous dinosaurs that include the famous genus Iguanodon, one of foundational members of the clade Dinosauria. Despite their very long history of research, several aspects of their systematic relationships and their evolutionary history remain somewhat nebulous.

Time-dependent behaviour of the Callovo-Oxfordian claystone-concrete interface

Journal of Rock Mechanics and Geotechnical Engineering, 2020
In the context of the Cigéo project, the French National Radioactive Waste Management Agency (Andra) is studying the behaviour of a deep geological facility for radioactive waste deposit in the Callovo-Oxfordian (COx) claystone.
