Virtual 3D models of the right bony labyrinth (red), petrosal bone (grey) and fossa subarcuata (yellow) of Panthera leo revealing ontogenetic changes of size proportions. A–D in dorsomedial view, posterolateral margin to the top and E–G in dorsal view, posterolateral to the top. A, E SMF 95010, neonate (IDAS 1.1); B, F SMF 15765, juvenile (IDAS 1.2); C, G SMF 38325, juvenile (IDAS 1.3); D, H SMF 4643, adult (IDAS 3). Abbreviation: ASC, anterior semicircular canal; co, cochlea; fs, fossa subarcuata; pc, petromastoid canal; PSC, posterior semicircular canal; asterisks (*) refer to unspecified connected cavities. Scale bars: 5 mm.
