Abstract & Keywords
Abstract: Turtles are divided into two categories, Cryptodira and Pleurodira, according to the way that a turtle retracts its neck into their shells. Monophyly of Cryptodira and Pleurodira is orthodoxly supported by the phylogenetic analyses of turtles based on morphological and molecular data. The molecular dating suggests that the two categories separated from each other in Early Jurassic. However, the interrelationships of turtles remain ambiguous, especially for Cryptodira. One of the main reasons is the inadequate knowledge of their morphology. Therefore, the morphological research into both the fossil and extant turtles is important for understanding the genealogical relationships and evolution of turtles. This paper provides a dataset of the µCT of Indotestudo elongata, including original CT slice images, stl-format files and videos derived from 3D models reconstructed from CT data. Indotestudo elongata is identified as a member of Testudinidae,which is a species of Cryptodira. Data for the skull of Indotestudo elongata based on µCT scan will contribute to further studies on turtles regarding their morphology and phylogeny. The printable 3D virtual models of the skull of Indotestudo elongata can be applied to research, teaching, and public education.
