Carbonate Sedimentation Rates Today and in the Past: Holocene of Florida Bay, Bahamas, and Bermuda vs. Upper Jurassic and Lower Cretaceous of the Jura Mountains (Switzerland and France)

Geologia Croatica, 2003
Lagoonal to intertidal sediments from the Holocene in Florida Bay,on the Bahamas, and in Bermuda are compared to similar facies in theKimmeridgian and Berriasian of the Swiss and French Jura Mountains.Dating by 14C permits the estimation of sediment ...

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

The Anatomical Record, Volume 309, Issue 8, Page 1995-2048, August 2026.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Early Berriasian ammonites from the Štramberk Limestone in the Kotouč Quarry (Outer Western Carpathians, Czech Republic) [PDF]

, 2013
Over 100 ammonites were collected from a block of bedded shallow-water Štramberk Limestone at a new location at the Kotouč Quarry, near Štramberk (Silesian Unit, Czech Republic). Berriaselline neocomitids, including Berriasella jacobi, B.

Clay diagenesis and low-grade metamorphism of Tithonian and Berriasian sediments in the Cameros Basin (Spain) [PDF]

, 2011
The clay mineral assemblages of the Tithonian and Berriasian sediments (Tera and Oncala Groups) in the eastern part of the Cameros basin are investigated at seven localities.

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.

Ethological variations in gauge in sauropod trackways from the Berriasian of Spain

Lethaia, 2012
Two sauropod trackways from the Early Cretaceous (Berriasian) of the Cameros Basin (Spain) show important variations in trackway gauge, along the same trackway. These variations seem to be associated with different behaviours; on the one hand with a significant variation in the direction of travel (turning phenomena) and on the other hand with a ...

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

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 ...
