Abstract
This contribution contains 3D models of the cranial skeleton and muscles in an elephantfish (Callorhinchus milii) and a catshark (Scyliorhinus canicula), based on synchrotron tomographic scans. These datasets were analyzed and described in Dearden et al. (2021) “The morphology and evolution of chondrichthyan cranial muscles: a digital dissection of the elephantfish Callorhinchus milii and the catshark Scyliorhinus canicula.” Journal of Anatomy.

INTRODUCTION
As the sister-group to bony fishes, the anatomy of sharks, rays and chimaeras (=chondrichthyans) plays a crucial role in our un- derstanding of jawed vertebrate evolution. The two constituent chondrichthyan groups — holocephalans (chimaeras) and elas- mobranchs (sharks and rays) — display wildly different cranial architectures, the origins of which have important implications for the origins of jawed vertebrate anatomy. In the associated manuscript (Dearden et al. 2021), we carried out a digital dissec- tion of two chondrichthyans widely used as model species, the elephantfish Callorhinchus milii and the catshark Scyliorhinus canicula, which we used to review evidence for the evolution of chondrichthyan cranial muscles in the fossil record. Resulting from this digital dissection are detailed models of the cranial and pharyngeal skeleton and associated muscles, which we present here (Fig.1and table1).
METHODS
The 3D surfaces were extracted in Mimics 21.0 (Materialise), using the segmentation threshold tool. This was done with a
combination of manual and interpolatory segmenting. Models were imported into Blender (blender.org), which was used to capture images. The models are provided here in .ply format, which are openable in many free software packages.
