If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
M. D. Uhen et al. 2008The Eurhinodelphinidae includes extinct medium to long-beaked small odontocetes from widely scattered early to middle Miocene localities (e.g. Abel, 1909, Kellogg, 1932), with a few possible records of late Oligocene age. They take their identity from the Belgian late early Miocene Eurhinodelphis cocheteuxi Du Bus 1867. The many reported bony diagnostic features (Kellogg 1925b, 1928, 1932; Muizon 1988b, 1991; Lambert, 2004; 2005a) include the following: rostrum very long; premaxillae toothless and extending beyond the mandible; premaxillary-maxillary suture on rostrum forms a prominent lateral fissure; mesorostral groove roofed by premaxillae; premaxillary fossae with a marked slope upwards to vertex; zygomatic process and postglenoid process of squamosal robust; posterior part of pterygoid hamulus long and conical. This group has previously been called Eurhinodelphidae and Rhabdosteidae (for the latter see Fordyce 1983 who followed Myrick 1979).
