Environmental Context of Hominin Foot Evolution

open access: yesAmerican Journal of Biological Anthropology, Volume 191, Issue 2, October 2026.
ABSTRACT Objectives This study investigates the environmental contexts that influenced the evolution of hominin foot morphology, focusing on when, where, and under what conditions key synapomorphies evolved. We test whether shifts in ecological conditions are associated with changes in locomotor function.

Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2574-2635, October 2026.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

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

open access: yesThe 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)

open access: yesThe 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).

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2636-2655, October 2026.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2379-2407, October 2026.
ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

Dynamic Evolution of a Storm‐Time “Super‐EPB” Event Over China on the Magnetically Disturbed Night of 01 December 2023

open access: yesSpace Weather, Volume 24, Issue 10, October 2026.
Abstract This paper investigates the dynamic evolution of a storm‐time “Super‐EPB” event over China on 1 December 2023 (Kp ≤ 7, SYM/H ≥ −130 nT) using multi‐instrument observations. Occurring near sunset as the IMF‐Bz abruptly turned southward, with auroral extension to midlatitudes, the “Super‐EPB” extended to 40°N with an apex height of ∼2,460 km ...

Divergent trajectories of genome architecture and chromosome evolution in ferns and angiosperms

open access: yesNew Phytologist, Volume 252, Issue 1, Page 427-442, October 2026.
Variation in key fern genomic traits across families, mapped onto a summary phylogenetic tree. Summary Ferns and angiosperms represent the two largest vascular plant lineages but exhibit striking genomic and ecological contrasts. We investigated whether differences in genome size, chromosome architecture, GC content, and stomatal traits reveal ...

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

open access: yesSedimentology, 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

Evidence for the continental origin of Pliocene deposits in the central Baja California peninsula, Mexico, and implications for controls on biodiversity

open access: yesSedimentology, Volume 73, Issue 6, Page 2488-2518, October 2026.
ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...
