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.

Y. Tanaka and M. Watanabe 2019Two synapomorphies of the Balaenopteridae were identified by the phylogenetic analysis in this study:
an abruptly depressed supraorbital process of the frontal to a level noticeably below the vertex with the lateral skull wall above the supraorbital formed by both parietal and frontal in anterior view (character 45); and shape of anteroventral angle of anterior process of periotic in med- ial or lateral view, slender and tapering to a point (char- acter 147). The holotype of Miobalaenoptera numataensis only preserves the periotic character 147. Three periotic diagnostic characters have previously been reported: a narrow triangular anterior process of the peri- otic (Character 20 of Ekdale et al. 2011; Bisconti 2010b); well-defined fossa for the malleus (Ekdale et al. 2011, character 43) and transversely elongated pars cochlearis (Geisler & Luo 1996, character 12). These characters were stated as the Family Balaenopteridae excluding Eschrichtius robustus in these studies.
