The velar chord and dynamic integration of the gular valve in crocodylians

open access: yesThe Anatomical Record, EarlyView.
Crocodilians have a unique gular valve that forms a seal between the oral cavity and the pharynx. The gular valve has traditionally been treated as two parts: a mobile ventral flap associated with the tongue and a fixed dorsal velum palatini. This work describes a connective tissue band, the velar chord, which functionally integrates the two parts of ...

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Segmentation of cortical bone, trabecular bone, and medullary pores from micro‐CT images using 2D and 3D deep learning models

open access: yesThe Anatomical Record, EarlyView.
Abstract Computed tomography (CT) enables rapid imaging of large‐scale studies of bone, but those datasets typically require manual segmentation, which is time‐consuming and prone to error. Convolutional neural networks (CNNs) offer an automated solution, achieving superior performance on image data.

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.
