The osteohistology of Orthosuchus stormbergi using synchrotron radiation microcomputed tomography

open access: yesJournal of Anatomy, EarlyView.
The osteohistology of Orthosuchus stormbergi is described for the first time. The primary bone tissue was lamellar bone. It had relatively thick bone walls, possibly indicating an aquatic lifestyle. Orthosuchus was a small bodied adult reaching a maximum body mass of about 1.2 kg.

Hindlimb biomechanics of Lagosuchus talampayensis (Archosauria, Dinosauriformes), with comments on skeletal morphology

open access: yesJournal of Anatomy, Volume 246, Issue 6, Page 948-973, June 2025.
The study constructs a 3D whole‐body biomechanical model of the Late Triassic archosaurian reptile Lagosuchus talampayensis, which includes reconstructions of the hindlimb musculature. The process of constructing the model revealed that numerous limb bones curated with the main specimens are from other, as‐yet‐undetermined archosaurs.

An interpopulation comparison of 3-dimensional morphometric measurements of the proximal humerus

open access: yesJSES International, 2020
Background: Precise anatomic reconstruction of the proximal humerus is essential to a favorable outcome of total shoulder arthroplasty. Because of the wide variation in the geometric features of the proximal humerus, prosthetic designs incorporating ...

Osteohistological signal from the smallest known phytosaur femur reveals slow growth and new insights into the evolution of growth in Archosauria

open access: yesJournal of Anatomy, EarlyView.
The paucity of small, skeletally immature individuals representing the earliest ontogenetic stages of extinct archosaurs complicates our understanding of the growth dynamics within and between species. The opportune finding of the smallest phytosaur femora reveals slow growth, a surprising signal considering that larger phytosaurs in North America have

An anatomical investigation of alkaptonuria: Novel insights into ochronosis of cartilage and bone

open access: yesJournal of Anatomy, Volume 246, Issue 6, Page 1053-1074, June 2025.
Examination of an alkaptonuria body highlights the susceptibility of all cartilage types and associated perichondrium to ochronotic pigmentation and the heterogeneity of ochronotic pigment distribution both within and between tissues. In joints, calcified cartilage pigments before non‐calcified cartilage.
