Is cranial anatomy indicative of fossoriality? A case study of the mammaliaform Hadrocodium wui

The Anatomical Record, EarlyView.
Abstract Determining the ecology of fossil species presents considerable challenges due to the often fragmentary preservation of specimens. The mammaliaform Hadrocodium wui from the Jurassic of China is known only from the cranium and mandible but may have had a fossorial lifestyle.

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

The 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.

Visualization of Organ Movements Using Automatic Region Segmentation of Swallowing CT [PDF]

arXiv
This study presents the first report on the development of an artificial intelligence (AI) for automatic region segmentation of four-dimensional computer tomography (4D-CT) images during swallowing. The material consists of 4D-CT images taken during swallowing.

Early life functional transitions impact craniofacial morphology in osteogenesis imperfecta

The Anatomical Record, EarlyView.
Abstract Early life behaviors have a profound role in shaping adult craniofacial morphology. During early life, all mammals undergo the dynamic transition from suckling to mastication, a period coinciding with rapid cranial biomineralization. Osteogenesis imperfecta (OI), a genetic disorder that impacts the production of type I collagen, disrupts ...

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

The 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 ...

MANDIBULAR SHAPE IN MYOSTATIN-DEFICIENT MICE: A GEOMETRIC MORPHOMETRIC ANALYSIS [PDF]

, 2012
The relationship between muscle function and mandibular morphology is unclear. Manipulating the size or function of muscle and then observing the effect on adjacent bone is one way to explore this relationship.

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

The 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

The 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 ...
