A Paleotectonic Atlas of the African Plate: Permian to Recent

Journal of Petroleum Geology, Volume 48, Issue 4, Page 231-279, October 2025.
ABSTRACT The fragmentary release of petroleum data defining the deep structure and stratigraphy of African basins has been integrated with existing literature to compile 19 tectonic maps over key geological intervals from Permian to Recent times. African plate margins range in their age of opening from Late Triassic (off Lebanon), through Early/Middle ...

Tithonian–Berriasian ammonites from the Baños del Flaco Formation, central Chile

Journal of Systematic Palaeontology, 2015
The Baños del Flaco Formation in central Chile contains abundant and well-preserved Tithonian (Late Jurassic) and scarce Berriasian (Early Cretaceous) ammonites. At Rio Maitenes in Curicó Province an assemblage referred to 10 genera and 12 species is here described.

Trace elements, rare earth elements and isotopes of poorly preserved fossils from lower Cretaceous carbonates (Eastern Black Sea): Implications for early diagenetic alteration

The Depositional Record, Volume 11, Issue 4, Page 1107-1131, September 2025.
Analysing Rare Earth Elements (REEs) and other trace elements together with stable isotope data in poorly preserved belemnites can provide valuable insights into early diagenetic pathways, water‐interaction processes, and even potential redox conditions.

Deformation and Sediment Provenance of the Forearc Basin in the Central Andes of Southern Peru

Tectonics, Volume 44, Issue 8, August 2025.
Abstract The linkages between the development of the forearc regions and the accompanying retroarc in contractional mountain belts remain unclear. In the central Andes of southern Peru, new results constrain the timing of deformation and the provenance of forearc basin fill during Cenozoic mountain building.

Relative sea-level change, climate, and sequence boundaries: insights from the Kimmeridgian to Berriasian platform carbonates of Mount Salève (E France) [PDF]

, 2018
The present study analyses the stratal architecture of the Late Jurassic (Kimmeridgian) to Early Cretaceous (Berriasian) sedimentary succession of Mount Salève (E France), and four Berriasian stratigraphic intervals containing four sequence-boundary ...

Fish remains from the Lower Cretaceous (Valanginian-Hauterivian) of Hárskút (Hungary, Bakony Mts) [PDF]

, 2017
Lower Cretaceous (Valanginian-Hauterivian) fish remains, collected in the Közöskút Ravine (nearby Hárskút, Hungary) in the 1960s are detailed here. Although the material is poorly preserved, it is of great importance, because this geographical region and

The origins of neural spine elongation in iguanodontian dinosaurs and the osteology of a new sail‐back styracosternan (Dinosauria, Ornithischia) from the Lower Cretaceous Wealden Group of England

Papers in Palaeontology, Volume 11, Issue 4, July/August 2025.
Abstract The Wealden Group of southern England was deposited during the late Berriasian to early Aptian interval. It records a critical time in the development of iguanodontian dinosaur diversity, which increased from low levels during the Jurassic to higher levels in the Aptian and Albian. A new iguanodontian dinosaur, Istiorachis macarthurae gen.

Barremian and Aptian (Cretaceous) sharks and rays from Speeton, Yorkshire, north-east England [PDF]

, 2004
Bulk sampling of a number of horizons within the upper part of the Speeton Clay Type section has produced teeth and other remains of sharks and rays from several poorly studied horizons.

Impacts of Pre‐Existing Structural Fabrics on Fault Growth and Evolution During Multi‐Phase Rifting: Case Study From the Central Browse Basin, North West Shelf of Australia

Basin Research, Volume 37, Issue 4, July–August 2025.
This study examines the development of fault patterns in a multi‐phase rift system and demonstrates how pre‐existing faults influence the geometries and distribution of subsequent fault systems. ABSTRACT In multi‐phase rifts, pre‐existing structural fabrics that are formed during earlier rifting stages can influence fault growth during later ...
