Variability of jaw muscles in Tunisian street dogs and adaptation to skull shape

open access: yesThe Anatomical Record, EarlyView.
Abstract The impact of artificial selection on the masticatory apparatus of dogs has been poorly studied, and comparative data with dogs subjected to more natural constraints are lacking. This study explores the jaw musculature of Tunisian street dogs, which are largely free from the influence of breed‐specific selection.

Dietary ecology of Smilodon across time and space: Additional perspectives from Smilodon gracilis and Smilodon fatalis in Florida

open access: yesThe Anatomical Record, EarlyView.
Dental microwear texture analysis of Smilodon samples from Florida's Pleistocene reveals moderate carcass utilization (like modern African lions) across space and time, with more subtle dietary shifts in response to fluctuating climates. Abstract Smilodon, the iconic saber‐toothed cat, was a Pleistocene apex predator comprised of three morphologically ...

Linking individual variation in facial musculature to facial behavior in rhesus macaques

open access: yesThe Anatomical Record, EarlyView.
Abstract Facial expression is a key component of primate communication, and primates (including humans) have a complex system of facial musculature underpinning this behavior. Human facial musculature is highly variable across individuals, but to date, whether other primate species exhibit a similar level of inter‐individual variation is unknown ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Lagomorph cranial biomechanics and the functional significance of the unique fenestrated rostrum of leporids

open access: yesThe Anatomical Record, EarlyView.
Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

Mesiodens in primary and permanent dentitions

open access: yesOral Surgery, Oral Medicine, Oral Pathology, 1975
Abstract A case of a mesiodens in the deciduous dentition followed by a mesiodens in the same location in the permanent dentition is presented and discussed.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Dental fluorosis in the European roe deer (Capreolus capreolus): A review of the pathological changes in the enamel of fluorotic cheek teeth and the abnormal pattern of dental wear in affected dentitions

open access: yesThe Anatomical Record, EarlyView.
Abstract This article reviews the pathological changes in the enamel of permanent mandibular cheek teeth and their sequelae in European roe deer from regions polluted by anthropogenic fluoride emissions. The primary (developmental) changes of fluorotic roe deer enamel are hypomineralization and microstructural aberrations, including enamel hypoplasia ...
