The relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Carnivora from the Sespe of the Las Posas Hills, California [PDF]

open access: yes, 1933
The generic assemblage of carnivores known at present from the Kew Quarry of the Las Posas Hills, Ventura County, California, is perhaps most noteworthy because of its resemblance to that recorded from the John Day.

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

open access: yesThe Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Evolutionary Impacts of Pattern Recognition Receptor Genes on Carnivora Complex Habitat Stress Adaptation

open access: yesAnimals, 2022
Many mammals develop specific immune responses owing to the changes in their ecological niche and diet that are essential for animal survival. However, pattern recognition receptors (PRRs) serve as the first line of defense in innate immunity and ...

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

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

open access: yesThe 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.

Segmental composition and nerve distribution of the brachial plexus in Galictis cuja

open access: yesThe Anatomical Record, EarlyView.
Abstract Galictis cuja is a neotropical mustelid with terrestrial locomotor habits, yet the anatomy of its brachial plexus has remained undescribed. This study characterizes the origin, organization, and distribution of the brachial plexus nerves in 15 adult specimens (30 antimeres).

A new basal caniform (Mammalia: Carnivora) from the middle Eocene of North America and remarks on the phylogeny of early carnivorans. [PDF]

open access: yesPLoS ONE, 2011
Despite a long history of research, the phylogenetic origin and initial diversification of the mammalian crown-group Carnivora remain elusive. Well-preserved fossil materials of basal carnivorans are essential for resolving these issues, and for ...
