). The interorbital region converges anteriorly and has beaded supraorbital margins. The braincase is large and rounded. The zygomatic plate is broad and its posterior margin is anterior to the alveolus of M1. The alisphenoid strut is present and the subsquamosal foramen is small, almost occluded by the long hamular process. It has the pattern 3 of carotid circulation (

) with small stapedial foramen, no squamosal-alisphenoid groove and no sphenofrontal foramen. The palatal bridge is short and wide, and the incisive foramen is bulletshaped and its margins are parallel to each other posteriorly, reaching the anterior edge of M1. The mesopterigoyd fossa is M-shaped and extends to the mid-line of the last molars. Posterior palatal pits are a simple and small perforation present on each side of the mesopterigoyd fossa or, in some specimens, two small perforations on one side of mesopterigoyd fossa. Sphenopalatine vacuities are either present as small slits, or absent if the mesopterigoyd roof is completely ossified. Bullae are small. Upper incisors are opisthodont. M1 has labial accessory root, and m1 has labial and lingual accessory roots. Anterocone/conid of upper and lower molars are divided in two conules/lids by the anteromedian flexus/flexid. Oblique paralophules are present in all upper molars and are relatively reduced in size, and the posterior part of M3 is reduced. The mental foramen opens laterally on the body of mandible and the capsular process of lower incisor alveolus is well developed as a conspicuous swelling.
