The present 3D Dataset contains 3D models of the cranium surface and of the bony labyrinth endocast of the stem bat Vielasia sigei. They are used by (Hand et al., 2023) to explore the phylogenetic position of this species, to infer its laryngeal echolocating capabilities, and to eventually discuss chiropteran evolution before the crown clade diversification.

The present 3D Dataset contains the 3D models of extant Chiropteran endocranial casts, documenting 16 of the 19 extant bat families. They are used by Maugoust & Orliac (2023) to assess the correspondences between the brain and brain-surrounding tissues (i.e., neural tissues, blood vessels, meninges) and their imprint on the braincase, allowing for eventually proposing a Chiroptera-scale nomenclature of the endocast.
