Diagnosis
ReferenceDiagnosis
M. D. Uhen et al. 2008Teeth unknown, but apparently long-rooted, probably resembling those of Agorophius and Prosqualodon; nasals long, narrow, and flattened dorsally; maxillae covering the anterior three fourths of the orbital portion of the frontals; orbit large, with thickened rim and prominent postorbital process; parietals meeting across the vertex of the skull behind the orbits; zygomatic process of squamosal relatively small, with small and nearly horizontal glenoid fossa; mastoid region thickened and produced obliquely downward and backward to or beyond the posterior edge of the condyles which are small and protuberant. Palatals large, expanded anteriorly, separated medially for more than half their length at the back end by a deep notch at the front end of their combined margin; pterygoids widely sundered, their free margins partly overarching the narial passage. A well-marked nasal chamber is present above the anterior end of the passage, and the vomer forms a cylinder that completely encloses the basal end of the mesethmoid cartilage (Allen, 1921a)
