Both extant boselaphines possess extensive frontal sinuses.
The frontal sinuses extend through the entire length and breadth of the frontal, up into the bases of the horncores, and out to the lateral margins of the orbital rim ( Fig. 5C, D View Figure 5 ). The sinuses are extensively strutted throughout. The supraorbital strut heads nearly directly caudally, and can be traced only to the plane including the rostral ends of the horncores. The interfrontal suture is well fused in all of the specimens examined here, and the midline strut has an undulating appearance in cross section, perhaps as a result of extensive remodelling. However, the left and right frontal sinuses do not communicate at any point.
The frontal sinuses of this taxon ( Fig. 5A, B View Figure 5 ) are similar to those of Boselaphus tragocamelus in most morphological aspects, except those listed as follows. The supraorbital strut is more distinct (unlike in Boselaphus tragocamelus ), and trends caudomedially from the caudal end of the supraorbital canal towards the midline strut. The bases of both the rostral pair of horncores as well as the caudal pair of horncores are pneumatized. The left and right sinuses are wellseparated along the caudal third of their length (without the thin midline strut), concomitant with the lateral placement of the horncores. The portion of the sinus in the base of the caudal horncores is unstrutted in all of the specimens studied here.
