Diagnosis
ReferenceDiagnosis
M. Bisconti et al. 2017Eubalaena ianitrix differs from Eubalaena shinshuensis in showing a distinctive anteroventral corner in the parietal–frontal suture and in having an anterodorsally protruded squamosal–parietal suture; it differs from the Eubalaena sp. from the early Late Pliocene of Tuscany (included in our diagnosis considering that in our phylogenetic analysis it represents a true right whale species needing a new species name) in having an anteriodorsally protruded squamosal–parietal suture; it differs from Eubalaena japonica in having the pterygoid exposed in the temporal fossa, in having posteromedially directed anterior borders of the palatine and in having anteriorly directed posterior borders of the palatine; it differs from Eubalaena australis in having a less protruding anteroventral corner in the parietal–frontal suture, in having an anterodorsally protruded squamosal–parietal suture, in having the pterygoid exposed in the temporal fossa and in having anteriorly directed posterior border of the palatine; it differs from Eubalaena glacialis in having a crest located at the squamosal–parietal–supraoccipital suture and in having anteriorly directed posterior border of the palatine.
