Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

open access: yesJournal of Anatomy, EarlyView.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs

open access: yesJournal of Anatomy, EarlyView.
Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

Relationship between carina size and sternum morphology in birds reflects physical constraints of body size and flight style

open access: yesJournal of Anatomy, EarlyView.
Sternum morphology varies among birds and is a function of body mass and order. The area of the sternum is inversely related to the area of the keel suggesting that the increase in bone mass associated with a large keel has been mitigated by a reduction in bone mass of the sternum.
