Figure 8 in Evolution and functional morphology of the frontal sinuses in Bovidae (Mammalia: Artiodactyla), and implications for the evolution of cranial pneumaticity

Figure 8. Digital reconstructions from computed tomography (CT) scan data of the skulls of Hippotragus niger (A–B; AMNH 83606) and Kobus ellipsyprymnus (C–D; YPM 9101), illustrating frontal sinuses and related anatomy. Skulls are shown in lateral (A, C) and dorsal (B, D) 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 on A and B, and the horns were truncated on all images. Scale bars: 5 cm.
