ABSTRACT We present novel 3D subsidence data enabling vertical movements' quantification during the early formation of the Pyrenean retro‐wedge. From Cenomanian to Turonian times, subsidence is relatively low (~26 ± 10 m/Myr), corresponding to a brief 10 Myr thermal re‐equilibration of the European lithosphere following the hyperextended rift episode ...

ABSTRACT In recent years, a wide array of tools originally developed for molecular dating analyses has been adapted for use within a morphological clock perspective. This is of paramount relevance for taxonomic groups that cannot be sampled in forms suitable for DNA extraction.

The origin and evolution of air sacs in pterosaurs and their forerunners
Pneumatized pterosauromorph vertebrae and their phylogenetic context. Abstract Although the existence of postcranial pneumaticity and the inferred presence of air sacs connected to the lungs are well established in Pterosauria, the origin of this system in pterosaurs remains unclear. We investigated skeletal pneumaticity in the Triassic pterosauromorph

Moving Beyond Morphology: Genomic Insights Into Evolutionary Histories of Haplosclerid Sponges
ABSTRACT Accurate taxonomic identification is essential for defining species boundaries and understanding biodiversity. However, this remains challenging for groups where morphological character evolution is poorly understood or diagnostic traits are absent.

Abstract Earth experienced a long‐term cooling trend during the middle‐late Devonian, culminating in the Late Paleozoic Ice Age (LPIA)—the longest icehouse in Earth's history. The onset of glaciation has been attributed to CO2 removal through silicate weathering, however previous carbon cycle models have failed to reproduce its timing. Here, we build a

Identifying Framboidal Pyrrhotite: A Proxy for Hydrothermal Alteration of Organic‐Rich Sediments
Abstract Framboidal pyrrhotite, in sharp contrast to framboidal pyrite, has been rarely reported, and its formation remains poorly understood. Here we report its clear identification in a shale‐gas well core and explore its potential as a proxy for diagenesis or low‐grade metamorphism of organic‐rich sediments.
