Fig. 17 in Braincase Of The Upper Devonian Shark Cladodoides Wildungensis (Chondrichthyes, Elasmobranchii With Observations On The Braincase In Early Chondrichthyans

Fig. 17. Postorbital region of Cladodoides braincase (surface rendering), oblique perspective detail views. (A) Posterolateral view; (B) anterolateral view; (C) anteromedial view; (D) posteromedial view. Differences from Gross (1937) involve the positions of the abducent and profundal nerve. The dorsum sellae overhangs the deep hypophyseal chamber, and the lateral hypophyseal ridge delimits the side wall of this chamber. The superficial ophthalmic ramus passes through the postorbital process and emerges posteriorly just above the main trigeminal and facial nerve foramina.
