Variation in parrot jaw musculature

The Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

Whole‐bone shape of hominoid manual proximal phalanges

The Anatomical Record, EarlyView.
Abstract Functional morphologists have long noted that skeletal adaptations in primate phalanges reflect locomotor behavior. While most studies have successfully used two‐dimensional measurements to quantify general features of phalanx shape, a whole‐bone three‐dimensional analysis may better capture more subtle aspects of phalanx morphology that have ...

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

The Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...
