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

open access: yesThe 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.

Morphological aspects of the liver of the Podocnemis expansa (Testudines, podocnemididae)

open access: yes, 2014
The liver of P. expansa was characterized morphohistologically. To this end, twenty livers from clinically healthy male and female Podocnemis expansa, weighing from 2.0 to 4,5 kg, supplied by the commercial breeder Fazenda Moenda da Serra, in Araguapaz, state of Goiás, Brazil, were analyzed macro-and microscopically.
