Morphology and osteo‐histology of the weigeltisaurid wing: Implications for aerial locomotion in the world's first gliding reptiles

open access: yesJournal of Anatomy, EarlyView.
This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late

Proximal femoral focal deficiency : a case report [PDF]

open access: yes, 2008
Proximal Femoral Focal Deficiency (PFFD) is a rare and complex congenital anomaly (1:50,000-200,000 population) that results in varying degrees of femoral hypoplasia with limb shortening and pelvic abnormalities.

Medullary radius as a major contributor to variance in the proximal femur: Insights from statistical shape modeling

open access: yesJournal of Anatomy, EarlyView.
Workflow from CT to PCA‐based shape modeling of the proximal femoral canal (n = 763). Feature maps (size, roundness, torsion, flare, curvature) reveal sex‐ and age‐dependent patterns; three PCs capture ≈68% of variance and summarize dominant anatomical changes. Insights inform implant sizing and design envelopes in cementless THA.

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

open access: yesJournal of Anatomy, EarlyView.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...
