Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution

Journal of Anatomy, EarlyView.
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

The wide gape of snakes: A comparison of the developing mandibular symphysis in sauropsids

Journal of Anatomy, EarlyView.
Our analysis explores the adaptations at the mandibular symphysis required to allow extreme lower jaw mobility in macrostomate snakes taking a comparative approach. Abstract The origin and evolution of snakes has been marked by the acquisition of many morphological and functional novelties, one of which is the possession of a highly kinetic skull ...

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

Journal 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

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

Journal 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 ...

Scaling of internal joint distance in the elbow of small‐ to medium‐sized mammals: Implications for range of motion analyses

Journal of Anatomy, EarlyView.
We investigated the internal joint distances (IJDs) of the humero‐ulnar and humero‐radial joint, within a sample of 15 small‐ to medium‐sized mammals and report isometric results. We also found that joint poses had no effect on IJDs and that IJDs scale isometrically within small species.
