BRAINCASE, BASICRANIAL AXIS, MEDIAN SEPTUM IN THE DINOCEPHALIA 26 I The fenestra ovalis pierces the basioccipital well above the lower edge, here formed by the strong basioccipital tubera. The epipterygoid has a fairly short footplate resting on the pterygoid and meeting the basisphenoid at the basipterygoidal process. Its ascending process which is fairly slender is directed somewhat anteriorly and meets the under surface of the parietal. The quadrate ramus of the pterygoid is low and Fig. 53

Sagittal view (Fig. 53B) The posterior part of the braincase is seen to have its lateral wall formed by the exoccipital, supraoccipital, opisthotic and prootic; the floor is formed by the basioccipital which is anteriorly not overlain by the prootics. The prootics fail to meet each other in the middle line so that the upper part of the sella.
