Abstract

The dorsal surface was deeply excavated at the level of the supraorbital foramina. The sutures between the bones involved in the formation of this surface were fused and were represented by shallow grooves. The nuchal crest showed a central tubercle and thickened lateral extremities. The nuchal tubercles were very large and were placed between the apex of occipital fossa and foramen magnum. The orbital rim was caudally incomplete as the zygomatic process of the frontal bone was separated from the frontal process of the zygomatic bone by a large gap. The external acoustic meatus was on the posterior surface of the zygomatic arch. The lacrimal foramina were two in number. Fossa canina was very deep and rough while the eminentia canina was very large. The muscular process was very large and did not converge rostrally. The tympanic bulla was small and laterally compressed and the styloid process was absent. The hypoglossal foramen was oval in shape and lied between the muscular process and the jugular process.
