Disentangling the depositional, tectonic and diagenetic history of a unique case of rhombic calcite in marine carbonate scree‐like deposits in the Cretaceous Cauvery Basin

The Depositional Record, Volume 12, Issue 5, November 2026.
A succession of marine deposited scree deposits got exposed to meteoric fluids due to sea level drop or tectonic uplift. This potentially caused a unique form of diagenetic transformation in scree deposits, that is the formation of micro rhombic calcite.

Suite of Regional Seismic Velocity Models for the U.S. Atlantic and Gulf Coastal Plains (CPVMv2.0): Incorporating Epistemic Uncertainty in Velocity Models

Earthquake Spectra, Volume 42, Issue 4, November 2026.
The U.S. Atlantic and Gulf Coastal Plain (CP) sediments are kilometers‐thick, low‐velocity deposits underlain by high‐velocity bedrock that create regional patterns of amplification and attenuation of ground motions. Capturing these effects is challenging because of the limited subsurface information available, particularly the shear wave velocity (VS)

On the Origin of the Tingidae (Insecta, Heteroptera)

Zoologica Scripta, Volume 55, Issue 6, Page 876-892, November 2026.
ABSTRACT The hypothesis of a Gondwanian origin of the family Tingidae (Insecta, Heteroptera) has been promoted and seems to be generally accepted by specialists. However, the area of emergence and diversification of the clade, South American or Australian, is still debated and cannot be solved without integrating Vianaidinae, a subfamily considered as ...

Separating Environmental Modulation From Source Intermittency in Methane Leakage From a Legacy Well in British Columbia

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Legacy oil and gas wells are an incompletely quantified source of greenhouse gas emissions and offer leakage pathways for subsurface gas migration if inadequately isolated. We present a high‐resolution, process‐based characterization of leakage dynamics at an integrity‐compromised legacy gas well in northeastern British Columbia using five ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, Volume 309, Issue 10, Page 2752-2789, October 2026.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

The Anatomical Record, Volume 309, Issue 10, Page 2739-2751, October 2026.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, Volume 309, Issue 10, Page 2790-2837, October 2026.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

Loss, persistence and reversal of phenotypic traits

Biological Reviews, Volume 101, Issue 5, Page 2119-2133, October 2026.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...
