A systematic comparative description of extant turtle humeri, with comments on humerus disparity and evolution based on fossil comparisons

The Anatomical Record, Volume 307, Issue 11, Page 3437-3505, November 2024.
Abstract The humerus is central for locomotion in turtles as quadrupedal animals. Osteological variation across testudine clades remains poorly documented. Here, we systematically describe the humerus anatomy for all major extant turtle clades based on 38 species representing the phylogenetic and ecological diversity of crown turtles.

Functional and Character Disparity Are Decoupled in Turtle Mandibles

Ecology and Evolution, Volume 14, Issue 11, November 2024.
Here, we compare functional disparity measured by biomechanical proxies and character disparity measured by discrete morphological characters in turtle jaws. Exploration of mandibular patterns reveals that several biomechanical configurations or character state combinations can lead to the same feeding type (i.e., convergence) or that high functional ...

The topological organization of the turtle cranium is constrained and conserved over long evolutionary timescales

The Anatomical Record, Volume 307, Issue 8, Page 2713-2748, August 2024.
Abstract The cranium of turtles (Testudines) is characterized by the secondary reduction of temporal fenestrae and loss of cranial joints (i.e., characteristics of anapsid, akinetic skulls). Evolution and ontogeny of the turtle cranium are associated with shape changes.

Chondrocranial anatomy of Testudo hermanni (Testudinidae, Testudines) with a comparison to other turtles

Journal of Morphology, Volume 285, Issue 7, July 2024.
Histology‐based 3D reconstructions of the chondrocrania (blue), palatoquadrates (purple), and columellae (yellow) of a younger (top) and an older (below) specimen of Hermann's tortoise, Testudo hermanni (Testudines), in ventral views. The first vertebra (green) is partially reconstructed. Based on Figure 3.
