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

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

Lower Devonian Tortilicaulis is an early tracheophyte and not a bryophyte

Fossil Imprint
Tortilicaulis D.Edwards is a genus of long-standing unknown affinity in which there are two species: the holotype T. transwalliensis D.Edwards, known only from coalified compressions and T. offaeus D.Edwards, Fanning et J.B.Richardson, known from an assemblage of minute, exceptionally well preserved charcoalified fossils from a Lochkovian deposit in ...

Reappraisal of the lithological units of the Wuguan Complex: implication for the Paleozoic evolution of the Qinling orogenic belt

Frontiers in Earth Science
The Wuguan Complex, located along the southern margin of the Shangdan suture zone, plays a critical role in investigating the tectonic evolution of the Qinling orogenic belt and constraining the collision timing between the North and South China Blocks ...

Earliest known coelacanth skull extends the range of anatomically modern coelacanths to the Early Devonian

, 2012
Coelacanths are known for their evolutionary conservatism, and the body plan seen in Latimeria can be traced to late Middle Devonian Diplocercides, Holopterygius and presumably Euporosteus.
