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

open access: yesJ 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

open access: yesPaleoceanography 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

open access: yesGeological 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

open access: yesThe 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

open access: yesBasin 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 ...

Mineralogy and palaeoenvironments: the Weald Basin (Early Cretaceous), Southeast England

open access: yes, 2017
Determination of the mineralogy of sedimentary rocks is important in palaeoenvironmental interpretations, especially when outcrop and field data are insufficient or not accessible.

HIDROGEOQUIMICA DE LOS MANANTIALES SULFHIDRICOS y FERRUGINOSOS DE LAS FACIES PURBECK-WEALD DEL NOROESTE DE LA CORDILLERA IBERICA (PROVINCIA DE SORIA)

open access: yes, 1994
The goal of this article is to study the chemical composition of the sulfide-bearingand iron-rich springs in Soria. These springs are mainly located on sedimentary rocks of the Purbeck-Weald facies and most precisely in the Oncala group materials ...

New age‐estimate data and implications for marine isotope stage 7 and 5e sea levels in Fenland, eastern England

open access: yesJournal of Quaternary Science, Volume 41, Issue 1, Page 36-60, January 2026.
ABSTRACT Only one last interglacial relative sea‐level indicator point (SLIP) has been recognised for Fenland, eastern England, and the nearest penultimate interglacial SLIP is located on the north Norfolk coast. Such limited information restricts the regional input to, and hence the relevance of, global reconstructions of late Middle and Late ...

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)

open access: yesBasin 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)

open access: yesSedimentology, 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 ...
