Figure 9 in Evolution and functional morphology of the frontal sinuses in Bovidae (Mammalia: Artiodactyla), and implications for the evolution of cranial pneumaticity

Figure 9. Digital reconstructions from CT scan data of the skulls of Taurotragus oryx (A–B; YPM 10471), Aepyceros melampus (C–D; YPM 9597), Oreotragus oreotragus (E–F; AMNH 27827), and Pantholops hodgsonii (G–H; AMNH 55819), illustrating frontal sinuses and related anatomy. Skulls are shown in lateral (A, C, E, G) and dorsal (B, D, F, H) views. The boxed areas indicate the region of the skull that has been rendered partially transparent in order to visualize the anatomy of the frontal sinuses. The horn sheaths have not been rendered in A and B, and they are truncated in C–H. Scale bars: 5 cm.
