Diagnosis
ReferenceDiagnosis
R. W. Fields 1957Skull long, narrow, with well-developed sagittal crest; orbit deep, rounded; rostrum long, narrow; masseteric fossa ovoid, deep; lacrymal large, contacts with frontal and maxillary; lacrymal duct large, deep in anterior rim of orbit, with accessory rostral opening above ventral zygomatic root; jugal forms small zygomatic plate with broad, deep notch anterior to squamosal suture; squamosal with posterior projection extending back to exoccipital and mastoid above bulla; auditory bullae not greatly enlarged, ovoid, deep; external auditory meatus with extended anterior wall, open below with enlarged accessory opening; paraoccipital process consederably elongated; incisive foramen narrow, elongate; palate short; internal nares V-shaped, anterior border opposite posterior margin of M2; palatines greatly expanded, nearly meeting anterior expansion of squamosal on alisphenoid bar; pterygoid thin, extends to bulla; tooth rows nearly meetanteriorly. Mandible with deep masseteric ridge; masseteric crest greatly expanded; symphysis long, slender; coronoid process large, high; inferior dental foramen elongate, placed below inferior pterygoid crest. Incisors slender, enamel face rounded, smooth; lower incisors somewhat procumbent, short, base lingual to m2; upper incisors tightly archeded, based well ahead of P4. Cheek teeth evergrowing, unilaterally hypsodont, with small deposits of cement between lobes, enamel limited to sides of lobes and area of cosntriction opposite deep reentrant plication; P4-M2 with two lobes separated by deep reentrant fold; M3 with aditional posterior flage; m1-m3 with two lobes separated by deep reentrant fold; p4 with additional, shallow, anterior reentrant plication resulting in one normal posterior lobe and two smaller anterior lobes.
