Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3169-3186, November 2026.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3123-3136, November 2026.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3091-3105, November 2026.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Enneapterygius pallidoserialis, a Junior Synonym of Enneapterygius erythrosoma (Perciformes: Tripterygiidae)

open access: yesSpecies Diversity
Enneapterygius pallidoserialis Fricke, 1997, previously considered a valid species, is regarded as a junior synonym of E. erythrosoma Shen, 1994. Re-examination of type specimens of both nominal species revealed that the meristic and morphometric ...

The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3077-3090, November 2026.
Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3036-3076, November 2026.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Uncovering the Diversity of Mesostoinae (Hymenoptera: Braconidae): A Glimpse Into the Australian Fauna Through a Study of Kangaroo Island

open access: yesAustral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT The Mesostoinae are a poorly understood braconid subfamily with unresolved morphological challenges and a complex taxonomic history. This study provides insight into the biodiversity of this subfamily on Kangaroo Island (KI), South Australia.
