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

open access: yesThe Anatomical Record, EarlyView.
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 ...

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

open access: yesThe Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

An Assessment of Anti-Ganglioside Antibodies for the Diagnosis of Avian Ganglioneuritis and Potential Correlation with Gross Lesions, Microscopic Findings and Serologic Titers in Cockatiels Challenged with Parrot Bornavirus

open access: yesAnimals
Avian ganglioneuritis is one of the most widespread diseases of psittacines and is caused by parrot bornavirus (PaBV). It has been suggested that PaBV causes a T-cell-mediated immunopathology comparable to Borna disease virus 1 (BoDV-1).
