Diagnosis
ReferenceDiagnosis
T. R. Lyson and W. G. Joyce 2009Diagnosed as being part of Baenidae by the location of the foramen posterius canalis carotici interni between the pterygoid and halfway along basisphenoid; triturating surface moderately expanded with lingual ridge reduced posteriorly; and well developed pterygoid and basioccipital contact. Member of Plesiobaena/Palatobaena grade based on greater development of parietal overlying crista supraoccipitalis compared to E. cephalica, S. estesi, and Pa. cohen; deep temporal emargination; no incipient secondary palate; short preorbital skull length compared to Boremys spp. and E. cephalica; jugal exposed in orbital margin. Autapomorphies include: bar between orbit and cheek emargination less than half the diameter of the orbit; small squamosal and quadratojugal contact.
