The articular surface is divided into two condyles separated by a deep groove. The lateral condyle is located slightly posterior to the inner condyle. A pit is present on the internal surface of the quadrate that would have received the stapes, although the stapes itself is not preserved. Braincase: The braincase of Galeops is represented by the internal surface of the dorsal half of the occiput (Fig. 4), the lateral surface of the prootic (Fig. 1), and the ventral s

Braincase: The braincase of Galeops is represented by the internal surface of the dorsal half of the occiput (Fig. 4), the lateral surface of the prootic (Fig. 1), and the ventral surface of the basisphenoid (Fig. 5). No sutures can be seen in the occiput. A small posttemporal fenestra is present, surrounded by the squamosal laterally and the occipital plate medially. A groove on the lateral surface of the prootic leads to the temporal fenestra. Two large paired internal carotid foramina are present in the basisphenoid just medial and par f. Figure 4.
