Intraskeletal histovariability and skeletochronology in an ornithopod dinosaur from the Maestrazgo Basin (Teruel, Spain). [PDF]

J Anat
Abstract Ornithopods are an extinct group of dinosaurs that were particularly abundant and diverse in the Cretaceous of the Iberian Peninsula, and whose abundance in the Maestrazgo Basin has allowed numerous taxa to be identified over the last decade. Many of these fossil remains are still taxonomically indeterminate and require a more detailed study ...

Astronomical Pacing of Middle Eocene Sea‐Level Fluctuations: Inferences From Shallow‐Water Carbonate Ramp Deposits

Paleoceanography and Paleoclimatology, Volume 38, Issue 11, November 2023., 2023
Abstract Astrochronologically calibrated deep‐sea records document the Cenozoic (66–0 Ma) global climatic cooling in great detail, but the magnitude of sea‐level fluctuations of the middle Eocene Warmhouse state (47.8–37.7 Ma) and the ∼40.3 Ma warming event of the Middle Eocene Climatic Optimum (MECO) is not well constrained.

Hinterland environments of the Late Jurassic northern Weald Basin, England

Geological Journal, Volume 58, Issue 7, Page 2555-2577, July 2023., 2023
This study reports detrital mineralogy, geochemical analysis and sedimentological data for the Corallian sandstones of the Weald Basin. The data reveal a mixed mafic‐felsic provenance in a warm humid climate for the Corallian sandstones. The study also reveals intense sediment modification and redistribution by hydrologic sorting and highlights the ...

Sphaerosiderites as sensitive recorders of non‐marine depositional and diagenetic history: Insights from the Lower Cretaceous Wealden Supergroup

The Depositional Record, Volume 7, Issue 3, Page 520-540, September 2021., 2021
Characterisation of sphaerosiderites from the Early Cretaceous Wealden Supergroup show morphological and elemental heterogeneity, attributed to complex variability in physiochemical conditions within a dynamic wetland system, supported by sedimentology and climate models.

Tectono‐sedimentary evolution of Jurassic–Cretaceous diapiric structures: Miravete anticline, Maestrat Basin, Spain

Basin Research, Volume 32, Issue 6, Page 1653-1684, December 2020., 2020
We illustrate for the first time mixed halokinetic depositional sequences in minibasins limited by salt walls displaying typical flap and hook geometries (salt‐welds and thrust‐welds after Cenozoic shortening), in the Miravete anticline and Maestrat Basin (Iberian Ranges), with Jurassic and Early Cretaceous ages and partly coeval to Iberia‐Europe ...

Anatomy of Rift‐Segmenting Transfer Zones: New Insights From the 3D Integrated Interpretation of the Southeastern Sector of the Basque‐Cantabrian Basin and the Pamplona Fault (Pyrenees, N Spain)

Basin Research, Volume 38, Issue 1, January–February 2026.
An updated view of the southern part of the Cantabrian‐Pyrenean junction through a 3D geological model shows the first conclusive evidence for the ~65 km‐wide diffuse Pamplona transfer zone linking the Basque‐Cantabrian and Mauleon segments of the Pyrenean rift. This transfer zone also affected the style of deformation and configuration of the Pyrenean

A model for the concomitant early formation of dolomite and fibrous clays in coastal bay systems: Evidence from the Eocene (Paris Basin, France)

Sedimentology, Volume 72, Issue 6, Page 1860-1898, October 2025.
ABSTRACT Detailed analysis of Lutetian–Bartonian deposits in the Paris Basin (‘Marnes et Caillasses’ Formation) provides new evidence of concomitant magnesian fibrous clays (palygorskite and sepiolite) and early microcrystalline dolomite. Although relatively uncommon in sedimentary archives, palygorskite and sepiolite are found in a wide range of ...

Hydrological Effects of the Westward Expansion of Mediterranean Climate and Revegetation in Atlantic–Mediterranean Transitional Headwaters

Hydrological Processes, Volume 39, Issue 6, June 2025.
Six Spanish mid‐mountain catchments in a transitional Atlantic–Mediterranean ecotone reveal a westward expansion of Mediterranean climate: reduced spring precipitation in historically Atlantic catchments and increased autumn rainfall, coupled with rising temperatures and widespread greening.

Salt Diapirs and Minibasins Along a Transect Across the Basque‐Cantabrian Pyrenees: Implications for Cover‐Basement Interaction During Rifting and Inversion

Tectonics, Volume 44, Issue 5, May 2025.
Abstract The Basque‐Cantabrian Pyrenees experienced Early Cretaceous rifting and latest Cretaceous to Cenozoic inversion, with the presence of prerift Upper Triassic Keuper salt influencing how deformation was accommodated. Considerable disagreement exists on the degree of decoupling of supra‐ and subsalt deformation, the amount of thin‐skinned ...

Unravelling the Nature and Origin of Jurassic to Early Cretaceous Unconformities Offshore Southwest Britain

Basin Research, Volume 37, Issue 2, March–April 2025.
The Base Cretaceous unconformity in Southwest Britain, Iberia, and adjacent North Atlantic basins is a composite of at least three unconformities formed during the Middle Jurassic, Late Jurassic–Early Cretaceous, and Mid‐Cretaceous. Seismic data reveal that the Jurassic–Early Cretaceous unconformity, linked to Berriasian uplift and North Atlantic ...
