Fig. 30 in Braincase Of The Upper Devonian Shark Cladodoides Wildungensis (Chondrichthyes, Elasmobranchii With Observations On The Braincase In Early Chondrichthyans

Fig. 30. Transverse sections through the occipital region of the Cladodoides braincase showing the subnotochordal septum and ''chambers'' (presumably cartilage­filled in life). (A) Slice 281; (B) slice 280; (C) slice 276. All of these features extend over fewer than 10 slices (approx. 3 mm) in this braincase, in contrast with the occipital region shown in figure 31.
