Black shale deposition during the Early Jurassic: Geochemistry of Pliensbachian and Toarcian sedimentary rocks of the Hunzen Well, Hils Syncline, Northwest German Basin

The Depositional Record, Volume 11, Issue 5, Page 1451-1478, November 2025.
Our research uses a multidisciplinary approach, including organic and inorganic geochemistry, biostratigraphy, carbon isotope geochemistry and organic petrography to reconstruct depositional conditions and organic matter accumulation during the Pliensbachian and Toarcian.

Synthesis of micropaleontological age constraints for the reconstruction of the Tethyan realm in the Lesser Caucasus (Armenia, Karabagh)

Comptes Rendus. Géoscience, 2023
We present new biostratigraphic results from two ophiolite outcrops in Armenia. The discovery of upper Tithonian–lower Berriasian diagnostic radiolarian species (Vallupus gracilis Li and Sashida) in the lower radiolarites of the Dali section allows to ...

An Upper Cretaceous arthropod assemblage from Villaggio del Pescatore (Campanian, Italy) and its implications for peri‐Tethyan palaeobiogeography and palaeoecology

Papers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract The Villaggio del Pescatore (VdP) fossil Lagerstätte represents the most significant Upper Cretaceous (lower–middle Campanian) palaeontological locality in Italy and the Mediterranean region. We present the first systematic revision of the VdP fossil assemblage with a focus on its previously undescribed arthropod fauna, providing new insights ...

Interplay Between Salt Tectonics and a Large Igneous Province in the Espírito Santo Basin (Brazil)

Tectonics, Volume 44, Issue 11, November 2025.
Abstract Salt tectonics provinces host numerous resources and are now targeted as potential areas of development for energy storage capacities such as underground storage in salt caverns. Sedimentary basins containing salt structures are common at passive margins where volcanic rocks, emplaced either during the lithospheric breakup or the post‐rift ...

Paleoenvironments of Berriasian–lower Hauterivian deposits in the Western Neotethys: Late development, demise and drowning of the Slivnitsa carbonate platform (Western Bulgaria)

Evolving Earth
Sedimentological and biostratigraphic results are used to interpret the Early Cretaceous history of the newly named Slivnitsa carbonate platform which existed on the northern Neotethyan margin.

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.

Ichnotaxonomic review of large ornithopod dinosaur tracks: temporal and geographic implications. [PDF]

PLoS ONE, 2015
BACKGROUND:Large ornithopod tracks are known from the Upper Jurassic to the uppermost Cretaceous rocks of all continents but Antarctica. They include the tracks historically called Iguanodon footprints, iguanodontid footprints, hadrosaur/hadrosaurid ...

Exhumation of the Sierra de Cameros (Iberian Range, Spain): constraints from low-temperature thermochronology [PDF]

, 2008
We present new fission-track and (U–Th)/He data from apatite and zircon in order to reconstruct the exhumation of the Sierra de Cameros, in the northwestern part of Iberian Range, Spain. Zircon fission-track ages from samples from the depocentre of the

Mode of Continental Thinning and Breakup Along the North Iberian‐Armorican Conjugate Margins in the Bay of Biscay

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Continental breakup involves multiple extension styles; each linked to unique structural and sedimentary processes. High‐angle, low‐angle, listric and antilistric normal faults develop at different stages and positions during rifting. The Bay of Biscay and its margins, a prototypical example of magma‐poor rifted margins during Jurassic ...

Uppermost Jurassic to Lower Cretaceous benthic foraminiferal biostratigraphy at ODP Site 765 on the Argo Abyssal Plain. [PDF]

, 1992
Benthic foraminifers were studied in 99 samples collected from the lower 200 m of Hole 765C. The studied section ranges from the Tithonian to Aptian, and benthic foraminifers can be subdivided into five assemblages on the basis of faunal diversity and ...
