Dataset of µCT scan of the skull of Indotestudo elongata (Reptilia: Testudinata)

Turtles are divided into two groups, cryptodires and pleurodires, according to how they retract their neck into their shells. Monophyly of Cryptodira and Pleurodira is strongly supported by the phylogenetic analyses of turtles based on morphological and molecular data. The molecular dating suggests that this two groups separate from each other in Early Jurassic. However, the interrelationships of the turtles are ambiguous, especially the Cryptodira, which mainly result from the inadequacy knowledge of their morphology. Therefore, the morphological research of both the fossil and extant turtles are 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, 3D printable stl files, animated videos. Indotestudo elongata is identified as a member of Testudinidae，which is a group of Cryptodira. Data for the skull of Indotestudo elongata based on µCT scan will contribute to further studies of turtles regarding their morphology and phylogeny. Three-dimensional virtual models of the skull of Indotestudo elongata can be 3D printed, with broad applications in research, teaching, and public education.

根据龟类收缩颈部进入壳内的方式，龟类被划分为两个群体：隐颈龟类和裸颈龟类。基于形态学和分子数据的系统发育分析，隐颈龟类和裸颈龟类的单系发生得到了强有力的支持。分子年代学研究表明，这两个群体在早侏罗纪时期开始分化。然而，龟类之间的相互关系尚不明确，尤其是隐颈龟类，这主要归因于对其形态学知识的不足。因此，对化石龟类和现存龟类的形态学研究对于理解龟类的谱系关系和进化过程至关重要。本文提供了一组关于印度星龟（Indotestudo elongata）的微CT数据集，包括原始CT切片图像、可3D打印的stl文件和动画视频。印度星龟被确认为龟鳖科（Testudinidae）的一员，该科属于隐颈龟类。基于微CT扫描的印度星龟头骨数据将为龟类在形态学和系统发育方面的进一步研究做出贡献。印度星龟头骨的三维虚拟模型可以进行3D打印，广泛应用于研究、教学和公众教育。
