An exclusive feature of turtles is their shell, which includes protection to their body. A dorsal and convex carapace forms the shell with bony plates fused to the ribs, which cover the back and some internal parts of the skeleton. A ventral and flat plastron, laterally joined by an area called the pons complete the ventral aspect of the shell. Turtles present a distinct skull pattern considered by some authors of anapsids. The skull is composed of bones fused through sutures, foramina and bone accidents. The anatomical description of these species can help discover their taxonomic clade, as well to compare morphological variations and possible family relationships. The carapace, plastron and skull anatomy knowledge can be useful for some techniques, such as necropsy, deflection, maceration, identification and illustration of bones. The aim of the present study was provide the identification and digital illustration of the skull and shell of the five species of turtles from the Podocnemididae family. This study allowed the acquisition of knowledge about the osteology of this order, by comparing the species of the same family, measuring the quantity, shape and absence of some structures, being visualized in the skull nineteen pairs of cranial bones, being them the frontal, prefrontal, postorbital, jugal, quadratus jugal, parietal, squamous, supraoccipital, exoccipital, basioccipital, exoccipital, basisphenoid, pterygoid, palatine, maxillary and premaxillary. And sixty bones, divided between the carapace and the plastron. This work may support future research and hypotheses regarding the morphology, osteology and taxonomy of these species.
