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 ...

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3106-3122, November 2026.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

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.

Citric‐Acid Polyester‐Modified Melamine–Formaldehyde Resins: Mechanistic Insights and Implications for Greener Decorative Laminates

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
Driven by the need for more sustainable materials in the laminate industry, poly(glycerol citrate) was introduced as a bio‐based modifier that significantly altered the cure kinetics and structural evolution of melamine–formaldehyde resins. Correlated FTIR, DSC, TGA, and rheological analyses revealed accelerated network formation, enabling lower ...
