Figure 5 in X-ray microcomputed and synchrotron tomographic analysis of the basicranial axis of emydopoid dicynodonts: implications for fossoriality and phylogeny

Figure 5. The lateral wall of the braincase of Pristerodon mackayi (BP/1/2642): right prootic (blue) in (A) anterior, (B) lateral, (C) posterior, (D) ventral and (E) medial views; and left opisthotic (golden) in (F) anterior, (G) lateral and (H) posterior views. afac, articulation facet concavity; ascc, attachment of the anterior semicircular canal; boa, basioccipital sutural area; bsa, parabasisphenoid sutural area; CNV, passage of the cranial nerve five (V); eoa, exoccipital sutural area; fa, facial foramen; flo, floccular fossa; fo, fenestra ovalis; jf, jugular foramen; lscc, attachment of the lateral semicircular area; lvb, opisthotic lateral vertical buttress; osu, opisthotic posterior vertical sulcus; ovmp, opisthotic ventromedial process; pa, pila antotica; pab, prootic anterior bulge; pad, pila antotica anterior depression; pdp, prootic dorsal process; prd, prootic lateral depression; pscc, attachment of the posterior semicircular canal; ptf, posttemporal fenestra; spa, supraoccipital sutural area; vea, vestibular area; ve, vestibule. The horizontal line pattern on the prootic in (B) represents the prootic depression. The diagonal square pattern in (F) represents the articular surface of the prootic. Scale bars equal 5 mm. The upper scale bar serves for (A-E) and the lower for (F-H).
