Fig. 19. Coronal CT images showing pneumaticity of the rostral portion of endoturbinal I (char. 17). (A) rostral portion contains no pneumatic cavities (char. 17.0), Petauroides volans, C370 (AMNH 150055); (B) small pneumatic cavity is present, which encompasses only a portion of the coronal cross section of the element (char. 17.1), Phalanger orientalis, C160 (AMNH 157211); (C) large cavity is present, which encompasses most or the entire coronal cross section of the element (char. 17.2), Didelphis virginiana, C270 (TMM M-2517). All scale bars equal 5 mm. Abbreviations: Endo, endoturbinal; ONS, ossified nasal septum; P1, first upper premolar.
