Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

Journal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

Comparative histological analysis of vertebrates reveals Triassic climate variability across southern Pangea

Journal of Anatomy, EarlyView.
Bone tissues of Triassic taxa reveal life history signals consistent with climatic variation across southern Pangea, spanning present‐day Brazil, Argentina, Zimbabwe, and India. Slower growth patterns within the Zimbabwean assemblage suggest a comparatively more arid intracontinental environment than those closer to the coast. Artwork by Andrey Atuchin.

How do forelimb long bones adapt in rhinoceroses? An in‐depth examination of their microanatomy

Journal of Anatomy, EarlyView.
Here, we study the bone structure in the forelimb long bones of the five extant species of rhinoceroses. By combining traditional description of virtual sections made on the bones (A) with in‐depth cartographies of the variation of bone compactness and anisotropy (B), we show how bone tissue can adapt to extreme forces and constraints in the second ...

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

Journal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.
