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 and P. D. Gingerich 2001Chrysocetus healyorum has features of Dorudontinae (particularly vertebral bodies that lack elongation seen in members of the Basilosauridae) but differs from other Dorudontines in having smooth enamel and lacking vertically ori- ented ornamentation on the upper premolars. In addition, the premolars are more gracile than those of Dorudon, and the upper premolars lack crenulations on the mesial and distal cingula like those of Zygorhiza (Kellogg 1936; see Fig. 1). Based on comparable skeletal elements, C. healyorum was larger than Saghacetus osiris and smaller than Pontogeneus bracbyspondylus.
M. D. Uhen 2004Chrysocetus has features of Dorudontinae (particularly vertebral bodies that lack elongation seen in members of the Basilosauridae) but differs from other Dorudontines in having smooth enamel and lacking vertically-oriented ornamentation on the upper premolars. In addition, the premolars are more gracile than those of Dorudon, and the upper premolars lack crenulations on the mesial and distal cingula like those of Zygorhiza (Kellogg 1936; see Fig. 1). Based on comparable skeletal elements, Chrysocetus is larger than Saghacetus osiris and smaller than Pontogeneus brachyspondylus.
M. D. Uhen 2008Chrysocetus is much smaller than both Basilosaurus and Cynthiacetus. In addition, Chrysocetus has smooth enamel on the crowns of the premolars, which distinguishes it from Dorudon and Zygorhiza.
M. D. Uhen 2013Chrysocetus healyorum has vertebral bodies that lack elongation seen in members of the genus Basi- losaurus. C. healyorum also has very smooth enamel and lacks vertically oriented ornamentation on the upper pre- molars. In addition, the premolars are more gracile than those of Dorudon, and the upper premolars lack crenula- tions on the mesial and distal cingula like those of Zygorhi- za. Based on comparable skeletal elements, C. healyorum was larger than Saghacetus osiris and smaller than mem- bers of the genera Dorudon, Cynthiacetus, and Basilosaurus (after Uhen and Gingerich, 2001).
