Figure 16. Posterolateral view of the right interior of the cranial cavity of adult S. crocodilurus (MVZ 204291). The view is through the foramen magnum toward the perilymphatic foramen and the medial aperture of the recessus scala tympani (RST). The long black hair passes through the lateral aperture of the RST (near the center of the right side of the image) and enters the cranial cavity via the medial aperture of the RST (near the center of the image). The width across the occipital condyle in this specimen is 3.9 mm.
