Figure 5 in Cephalic salt gland evolution in Mesozoic pelagic crocodylomorphs

Figure 5. Internal rostral anatomy of metriorhynchids Cricosaurus araucanensis [MLP 72-IV-7-1 (A, B, G, H)], Thalattosuchus superciliosus [NHMUK PV R 11999 (C, D, I, J)] and TorƲoneustes coryphaeus [MJML K1863 (E, F, K, L)]. A, B, Cricosaurus araucanensis in dorsal (A) and left lateral view (B). C, D, Thalattosuchus in dorsal (C) and left lateral view (D). E, F, TorƲoneustes in dorsal (E) and left lateral view (F). G-L, transverse CT slices of nasal cavity olfactory region of Cricosaurus araucanensis (G, H), Thalattosuchus (I, J) and TorƲoneustes (K, L) showing the pre-orbital fenestra external opening (G, I, K) and dorsolateral expansions of olfactory region where salt glands are inferred (H, J, L). All skulls are rendered transparent. Internal reconstruction colours: nasal cavity, yellow; nasopharyngeal ducts, pale yellow; antorbital cavity/sinus, green; preobrital fenestra, light green. Scale bars equal 50 mm (A-F). and 10 mm (G-L).
