Fig. 28 in Braincase Of The Upper Devonian Shark Cladodoides Wildungensis (Chondrichthyes, Elasmobranchii With Observations On The Braincase In Early Chondrichthyans

Fig. 28. Occipital region of the Cladodoides braincase (surface rendering), oblique perspective detail views: (A) posterolateral view; (B) posteromedial view; (C) anteromedial view; (D) anterolateral view. This block overlaps slightly with that shown in figure 22, repeating the tip of the dorsal otic ridge and posterior semicircular canal. The hypotic lamina is fused to the capsular wall laterally, forming a glossopharyngeal canal. The position of the vagal nerve is indicated by an expansion in the otico­occipital fissure above the glossopharyngeal canal.
