Fig. 37 in The Braincase In Paleozoic Symmoriiform And Cladoselachian Sharks

Fig. 37. Original reconstructions of the neurocranium in Cobelodus aculeatus, after Zangerl and Case (1976: figs. 7, 10). A, ventral reconstruction of endocast in FMNH PF 3090; B, dorsal reconstruction of endocast; C, lateral view of the endocast, with nerve canals identified; D, dorsal outline of the braincase with the endocast inexplicably shown in ventral view, and positioned completely between the orbits as in a platybasic braincase. Once the midline of the endocast is recognized (indicated here by heavy dashed lines added to the original reconstructions in A and B), the doubling-up of structures is immediately evident.
