Several occurrences of osteomyelitis in dinosaurs from a site in the Bauru Group, Cretaceous of Southeast Brazil

The Anatomical Record, Volume 309, Issue 3, Page 642-648, March 2026.
Abstract This study investigates the occurrence of osteomyelitis in non‐avian dinosaurs, focusing on the Ibirá locality, a site with a high incidence of this pathological condition. We analyzed six new osteopathic sauropod specimens from the Upper Cretaceous of Brazil.

The lower jaw of Devonian ray‐finned fishes (Actinopterygii): Anatomy, relationships, and functional morphology

The Anatomical Record, Volume 309, Issue 3, Page 550-602, March 2026.
Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Characterization of Respirable Particulate Matter Collected With Cyclones in School Environments of the Metropolitan Region of Rio de Janeiro

X-Ray Spectrometry, Volume 55, Issue 2, Page 366-373, March/April 2026.
ABSTRACT The relevance of investigating atmospheric particulate matter (PM) in the school environment is related to its significant impact on the health of school‐age children. In this context, the present study focuses on the characterization of suspended atmospheric PM in eight elementary schools located in the metropolitan region of Rio de Janeiro ...

A suture in time: The ontogeny of cranial suture morphology in mammals

Journal of Anatomy, Volume 248, Issue 3, Page 501-516, March 2026.
Mammal cranial sutures are important indicators of the biomechanical and developmental pressures acting upon the skull. Across three prominent sutures dividing the vault of the mammalian skull, divergent patterns emerge both taxonomically and developmentally.

Whole‐bone shape of hominoid manual proximal phalanges

The Anatomical Record, Volume 309, Issue 2, Page 245-270, February 2026.
Abstract Functional morphologists have long noted that skeletal adaptations in primate phalanges reflect locomotor behavior. While most studies have successfully used two‐dimensional measurements to quantify general features of phalanx shape, a whole‐bone three‐dimensional analysis may better capture more subtle aspects of phalanx morphology that have ...

Taking machine learning with a grain of sand: Sediment Analysis Neural‐network Data‐engine (SAND‐e) reveals sedimentological differences between turbid and clear‐water reefs

The Depositional Record, Volume 12, Issue 1, February 2026.
Using machine learning, researchers can count and crudely identify sand grains from coral reefs automatically. This will allow us to generate larger datasets to answer sedimentological questions. Abstract Sediment is an important facet of sand cay reefs as it is responsible for reef accretion and island formation, with shifts in the proportions of ...
