Skull with long, broad rostrum flanked by deep zygomatic notches; interorbital region hourglass-shaped, with squared supraorbital margins; braincase oblong and usually without distinct temporal crests, but lambdoidal and nuchal crests often well developed in older adults. Posterior margin of zygomatic plate dorsal to M1 alveolus. Jugal present but not large (the maxillary and squamosal zygomatic processes overlapping in lateral view but not in contact). Nasals short, not extending posteriorly beyond lacrimals; lacrimals equally sutured to maxillary and frontal bones. Frontosquamosal suture colinear with frontoparietal suture in most specimens. Parietals with broad lateral expansions. Incisive foramina long, usually extending posteriorly to or between M1 alveoli; usually widest at midlength and tapering symmetrically anteriorly and posteriorly. Posterolateral palatal pits large, usually complex, and recessed in deep fossae; mesopterygoid fossa penetrating anteriorly between maxillae but not between molar rows; bony roof of mesopterygoid fossa perforated by large sphenopalatine vacuities. Alisphenoid strut absent (buccinatormasticatory foramen and accessory foramen ovale confluent). Stapedial foramen and posterior opening of alisphenoid canal small; squamosalalisphenoid groove and sphenofrontal foramen absent; secondary anastomosis crosses dorsal surface of pterygoid plate (
