3D Quantification of Subsidence During Pyrenean Retro‐Wedge Initiation: Role of Structural and Thermal Inheritance on Hyperextended Margin Inversion (Aquitaine Basin)

Terra Nova, EarlyView.
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 ...

Subcritical Cracking Associated With Subgrain Rotation Recrystallisation in Quartz Inferred From Cathodoluminescence Study

Terra Nova, EarlyView.
ABSTRACT We employed cathodoluminescence (CL) to study deformed quartz phenocrysts from the Cretaceous granite porphyry in SW Japan and observed fracture‐like planar structures appearing as CL‐dark bands. These CL‐dark bands were aligned with low‐angle grain boundaries formed by subgrain rotation recrystallisation.

Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

Terra Nova, EarlyView.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

Evaluating Bayesian Morphological Clocks for Estimating a Dated Phylogeny in a Relict and Fossil‐Rich Family of Wasps (Hymenoptera, Chrysidoidea)

Zoologica Scripta, EarlyView.
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.

Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework

American Journal of Human Biology, Volume 38, Issue 2, February 2026.
ABSTRACT Objectives Altitude shapes human morphology as highland populations must cope with cold and hypoxic environments. Although Andean highlanders have been proposed to exhibit larger and deeper ribcages, this idea is mainly based on research using disarticulated skeletal elements or non‐South American controls. The objective of this research is to

Silesaurid (Archosauria: Dinosauriformes) remains from the base of the Dockum Group (Late Triassic: Otischalkian) of Texas provide new insights to the North American record of dinosauriforms

The Anatomical Record, Volume 309, Issue 2, Page 293-313, February 2026.
Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...

Discharge Modulates the Dominance of Downstream Carbon Export Over Evasion in a Boreal Headwater Stream

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Carbon dioxide (CO2) evasion and downstream export of carbon (C) from headwater streams represent important fluxes in the global C cycle. Yet, these fluxes are generally studied in isolation, leaving gaps in the understanding of the overall role of streams in the C cycle.
