Illuminating the dark mess of fibers: Application of circular cross polarized light in unravelling the bone tissue structure of the dermal pectoral girdle of Metoposaurus krasiejowensis

open access: yesJournal of Anatomy, EarlyView.
Circular cross polarized light reveals the fine stucture of dermal bone tissue of a metoposaurid amphibian from the Late Triassic. Top right image shows the looped interwoven fibered bone when illuminated with circular polarized light displaying increased bone matrix intricacy compared to the same region of the bone when visualized with traditional ...

3D reconstruction of shoulder muscles in hominoid primates: Correlating scapular attachment areas with muscle volume

open access: yesJournal of Anatomy, Volume 246, Issue 5, Page 709-723, May 2025.
Digital muscle reconstructions are opening up a whole new world in understanding anatomy! In this study, we are thrilled to show that surface scans can capture rotator cuff volumes across a range of hominoids, while identifying challenges with less well‐defined muscles like the teres major.

The osteohistology of gorgonopsian therapsids and implications for Permo‐Triassic theriodont growth

open access: yesJournal of Anatomy, Volume 246, Issue 6, Page 987-1000, June 2025.
Permian gorgonopsian therapists had rapid, annually interrupted growth and show longer lifespans than early Triassic therapists. Abstract During the Late Permian, saber‐toothed gorgonopsian therapsids were the dominant terrestrial predators, playing crucial roles as apex predators alongside therocephalian therapsids within Permian terrestrial ...

Evaluation of the endocranial anatomy of the early Paleogene north African gavialoid crocodylian Argochampsa krebsi and evolutionary implications for adaptation to salinity tolerance in marine crocodyliforms

open access: yesJournal of Anatomy, Volume 246, Issue 6, Page 974-986, June 2025.
Abstract Argochampsa krebsi is a gavialoid crocodylian from the early Paleogene of North Africa. Based on its recovered phylogenetic relationship with South American species, it has been inferred to have been capable of transoceanic dispersal, but potential anatomical correlates for a marine lifestyle have yet to be identified.

Exploration of the covariation signal between cortical bone and dentine volumes across the upper limb bones and anterior teeth in modern humans and relevance to evolutionary anthropology

open access: yesJournal of Anatomy, EarlyView.
Using microtomographic scans of modern human arm and forearm bones and anterior dentition, we quantified cortical bone and dentine volumes and their topographic distribution. Our results revealed a co‐variation between cortical bone and dentine volumes, suggesting shared factors influencing their postnatal development.

Locomotor signals in the trabecular structure of the hominoid clavicle

open access: yesJournal of Anatomy, EarlyView.
This study investigates clavicular trabecular bone architecture in apes, linking mechanical loading to locomotor behavior. Regions with high rBV/TV values correspond to muscle attachment sites, with taxa‐specific differences in trabecular parameters reflecting varied muscle recruitment during locomotion.
