Diagnosis
ReferenceDiagnosis
A. M. Forasiepi et al. 2015Large Borhyaenidae characterized by a mas- sive skull, short rostrum and wide palate. It differs from other borhyaenids (Borhyaena and Arctodictis) by having nasals extended beyond the level of the postorbital pro- cess, jugal extended more anterior than the lacrimal, post- orbital process poorly developed and formed by the nasal and frontal, distinct preglenoid process of the squamosal, squamous part of the squamosal pierced by large foramina for emissary veins, dentary with coronoid process markedly inclined (anterior coronoid crest at 132 from the alveolar line); abrupt change in size between p1 p2 and p3; upper molars with broader stylar shelf on M3 and ectocingulum extending backwards up to the level of the metacone, M4 with three roots; lower molars with better developed talonid and distinct metaconid on m2 m4 sep- arated from the talonid.
