Figure 7

Ventrolateral views of skulls of Chrysospalax trevelyani (A, TM 40501) and Calcochloris obtusirostris (B, ZMB 85341, image reversed). Curved blue arrow in A represents foramen for stapedial ramus inferior subsumed within foramen ovale; straight blue arrow in B represents foramen for stapedial ramus inferior distinct from foramen ovale. Note also distance between sphenorbital fissure and foramen ovale in B exceeding maximum length of foramen ovale aperture, whereas in A the distance between the two is similar to maximum length of foramen ovale. Abbreviations are "eam" = external auditory meatus, "fo" = foramen ovale, "sof" = sphenorbital fissure. Scale bars = 5 mm.
