Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

The Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

In Vivo 3‐Dimensional Glenohumeral Joint Geometry Based Upon Magnetic Resonance Imaging and Computed Tomography Analysis Shows Deeper, Thicker, and Taller Glenoid Labrum Morphology at 12 O’Clock Position in Healthy Young Adults

Arthroscopy, EarlyView.
Purpose To investigate location‐ and sex‐specific glenoid labrum morphology of healthy young adults in vivo, and the labrum's effects on depth and radius of curvature (ROC) of the glenohumeral joint. Methods Healthy young adults with no history of shoulder surgery, injury, or instability underwent computed tomography and magnetic resonance imaging ...
