Synopsis of the Genera of Eucanthini Nikolajev, 2002 (Coleoptera: Geotrupidae), With Two New Genera From Australia and South America

open access: yesAustral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Here, we review the generic classification of Eucanthini, resulting in the redefinition of Eucanthus Westwood, 1848 and erection of two new genera. Under this new framework, Eucanthus is restricted to six North American species, while two monotypic genera are described from the Southern Hemisphere: Antoniocanthus gen. nov.

Comparative histological analysis of vertebrates reveals Triassic climate variability across southern Pangea

open access: yesJournal of Anatomy, Volume 249, Issue 5, Page 989-1004, November 2026.
Bone tissues of Triassic taxa reveal life history signals consistent with climatic variation across southern Pangea, spanning present‐day Brazil, Argentina, Zimbabwe, and India. Slower growth patterns within the Zimbabwean assemblage suggest a comparatively more arid intracontinental environment than those closer to the coast. Artwork by Andrey Atuchin.

Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2725-2738, October 2026.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

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 ...

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2656-2697, October 2026.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...
