This contribution contains 3D models of the cranial endoskeleton of three specimens of the Permian ‘acanthodian’ stem-group chondrichthyan (cartilaginous fish) Acanthodes confusus, obtained using computed tomography. These datasets were described and analyzed in Dearden et al. (2024) “3D models related to the publication: The pharynx of the iconic stem-group chondrichthyan Acanthodes Agassiz, 1833 revisited with micro computed tomography.” Zoological Journal of the Linnean Society

The present 3D Dataset contains 3D models of the cranial, visceral, and pectoral endoskeleton of Iniopera, an iniopterygian stem-group holocephalan from the Pennsylvanian of the USA. These data formed the basis for the analyses carried out in Dearden et al. (2023) “Evidence for high-performance suction feeding in the Pennsylvanian stem-group holocephalan Iniopera” PNAS.

The present 3D Dataset contains the 3D models of Carboniferous-Permian chondrichthyan neurocrania analyzed in “Phylogenetic implications of the systematic reassessment of Xenacanthiformes and ‘Ctenacanthiformes’ (Chondrichthyes) neurocrania from the Carboniferous-Permian Autun Basin (France)”.

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.
