The Jurassic–Cretaceous Transition in the Slovenian Basin (Alpine Atlantic): Further Evidence for Palaeoenvironmental Record in Pelagic Sediments

Geochemistry, Geophysics, Geosystems
Over the vast area of present‐day Europe, the Tithonian–Berriasian transition was a time of climate aridization, which was supposedly related to the more general trend of the latest Jurassic–earliest Cretaceous cooling and restrictions in atmospheric ...

Paleo-Depositional Environments of Mirdita Zone During the Upper Jurassic–Lower Cretaceous

Albanian Journal of Natural and Technical Sciences
To decipher the paleo-depositional environments and the geodynamic evolution of the Mirdita Zone during the Upper Jurassic–Lower Cretaceous, as well as the timing of the emplacement of the underlying ophiolitic deposits, several areas with different ...

The Glacial Legacy of the Geneva Basin: Morphology and implications of an intricate tunnel valley system revealed from 3D seismic data

Journal of Quaternary Science, Volume 41, Issue 5, Page 732-753, July 2026.
ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

LATE JURASSIC AND EARLY CRETACEOUS AMMONITES FROM THE WEIMEI FORMATION IN GYANGZE, SOUTHERN TIBET

Rivista Italiana di Paleontologia e Stratigrafia, 2004
The Weimei Formation in southern Tibet is a shallow marine sequence accumulated in the northern margin of the Indian subcontinent. It has been dated as Tithonian based on ammonites such as Haplophylloceras strigile (Blanford), Berriasella sp.

Spatial and Temporal Distribution of Salt‐ and Shale‐Detached Contractional Deformation, Mexican Northwestern Gulf of Mexico

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In the northwestern Gulf of Mexico, gravity‐driven contractional deformation is recorded across the Salina del Bravo, the Perdido and Peripheral fold belts, and the Mexican Cordilleras. Integrating seismic interpretation, structural mapping, and analysis, we examine the spatial and temporal partitioning of shortening above three principal ...

Minimal Perturbation of the Global Mercury Cycle by the Paraná–Etendeka Large Igneous Province (PE–LIP) During the Onset of the Valanginian Weissert Event

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The Valanginian positive carbon isotope excursion (Weissert Event, ca. 135 million years ago) documents a major global carbon cycle and climate perturbation. Radioisotopic dating suggests that this event was broadly contemporaneous with an interval of profoundly enhanced volcanic activity during the emplacement of the Paraná–Etendeka Large ...

FIXING A BASAL BERRIASIAN AND JURASSIC-CRETACEOUS (J-K) BOUNDARY - IS THERE PERHAPS SOME LIGHT AT THE END OF THE TUNNEL?

Rivista Italiana di Paleontologia e Stratigrafia, 2011
Our tentative proposal is that several biological markers have potential to help define any putative boundary in the traditional basal Berriasian interval.

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

A deep dive into the fossil record of diving beetles (Coleoptera: Dytiscidae): Bayesian inferences elucidate their origin and pulsed diversification at the genus level

Palaeontology, Volume 69, Issue 3, 2026.
Abstract Predaceous diving beetles (Dytiscidae) are among the best‐known and most extensively studied beetle clades. Their fossil record, however, remains surprisingly sparse and uneven, failing to reflect their broad extant diversity. Consequently, the study of their evolutionary history, leveraging the fossil record, particularly their ...

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.
