Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae

Journal of Anatomy, Volume 249, Issue 4, Page 787-802, October 2026.
We present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...

1D Basin Modelling of Upper Jurassic to Upper Cretaceous Source Rocks in the Southern Pletmos Sub‐Basin, Outeniqua Basin, Offshore South Africa

Journal of Petroleum Geology, Volume 49, Issue 4, Page 1382-1411, October 2026.
ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2415-2430, October 2026.
Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...

Spatial and temporal evolution of a coastal erg margin: The Middle Jurassic Page Sandstone, southern Utah, USA

Sedimentology, Volume 73, Issue 6, Page 2081-2119, October 2026.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Recognition of fossil keratose sponges in carbonates using petrographic and machine‐learning classification

Sedimentology, Volume 73, Issue 6, Page 2246-2280, October 2026.
ABSTRACT Filamentous, anastomosing spar‐filled networks in Phanerozoic carbonates have been interpreted as the mineralised remains of keratose (non‐spiculate) sponges, yet their recognition remains contested because fabrics of broadly similar appearance may arise from microbial, diagenetic or physical processes. This study combines direct fossil–modern

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

Sedimentology, Volume 73, Issue 6, Page 2353-2380, October 2026.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

Sedimentology, Volume 73, Issue 6, Page 2417-2453, October 2026.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

The Jurassic flora of Sardinia — A new piece in the palaeobiogeographic puzzle of the Middle Jurassic

Review of Palaeobotany and Palynology, 2015
Abstract The Middle Jurassic flora of Sardinia has been studied, and 24 taxa (19 genera) belonging to horsetails, ferns (Phlebopteris, Hausmannia, Coniopteris, Todites, Cladophlebis), seed ferns (Sagenopteris, Ptilozamites), cycadophytes (Nilssonia, Pterophyllum, Cycadeospermum, Ptilophyllum, Williamsonia, Weltrichia, Taeniopteris), ginkgophytes ...

Paleophytogeography of the Siberian Paleofloristic Region in the Early Jurassic and First Half of the Middle Jurassic

Doklady Biological Sciences, 2022
The results of a comparative analysis of taphofloras of the Early Jurassic and first half of the Middle Jurassic of the Siberian paleofloristic region are considered. For this time interval, a significant similarity in the systematic composition of the taphofloras of Western Siberia and Northern China is revealed.
