Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

open access: yesThe Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Rotational Vibration of a Helical Gear Pair with Modified Tooth Surfaces : Modified Tooth Surface and Its Equivalent Tooth Profile

open access: yesJSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1993
Modified tooth profiles and their deflections cause a gear pair to contact away from the theoretical line of action and result in transmitting inconstant rotational motion. Those actual points of contact and their tooth actions can be described using tangential-polar coordinates by giving the measured single flank error and the tooth-spring constant ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

open access: yesThe Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

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

open access: yesThe 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).
