Moschops capensis 11972 X £, The endocranial cavity as graphically recon- structed from cross-sections. A. Lateral view. B. Dorsal view. Xll The sphenoidal complex (Fig. 25) In the accompanying figure some cross-sections through the sphenoidal region show the relations of the constituent elements. 70. At the level of the olfactory lobe the orbitosphenoids in section present a Y enclosing the brain from below, above and from the sides. Dorsally they abut against the lower face of the frontals. 10 mm anteriorly the septosphenoid is Y-shaped and dorsally abuts against the orbitosphenoid, which is a small elongated median bone intercalated between the two frontals. 14 mm anteriorly the brain forms a pair of olfactory tracts separated by a median pillar formed of the septosphenoid. Above this there is still an orbitosphenoid which has become narrower and shallower. 82. 5 mm further forward there is still a narrow orbitosphenoid and the olfactory bulbs are exposed laterally. The septum formed by the septo- sphenoid is greatly thickened. 88. The obitosphenoid has terminated and the upper part of the septum is still wide, whereas the lower part is narrow and may represent a pre- sphenoid. This rests on the parasphenoidal rostrum. 74- Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
