FIGURE 36. Dorsolateral view of the virtual braincase of OMNH 58340 with the parietal, left laterosphenoid, left prootic, and left sections of the supraoccipital and exoccipital/opisthotic removed. The flat edges of the parasphenoid and of the supraoccipital and exoccipital to the left and right, respectively, are artifacts of the CT scanning, and represent the limits of the data set. The supraoccipital (pink), exoccipital (brown), and orbitosphenoid (light green) were sectioned to allow for viewing of structures that would normally be covered by these elements. The computer program used to do this randomly assigns interior colors to the models, hunter green in the case of the supraoccipital, light blue in the case of the exoccipital, and maroon for the orbitosphenoid. Anterior is to the left. Abbreviations: bpt - basipterygoid process; dVIII - dorsal ramus of the acoustic nerve; ed - endolymphatic duct; mp - median process of the basioccipital; pf - area of the pontine flexure; vp - ventral process of the supraoccipital; vVIII - ventral ramus of the acoustic nerve.
