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 2004Members of the genus Dorudon can be distinguished from other archaeocetes based on overall size, and other morphological characteristics. Members of the genus Dorudon are considerably larger than Saghacetus , and much smaller than members of the genus Pontogeneus. Saghacetus lacks the long narial process of the frontals which is characteristic of the genus Dorudon. Members of the genus Dorudon can be distinguished from the members of the genus Zygorhiza based on the lingual cingula on P2-3. While members of both genera have cingula on the mesial and distal ends of P2-3, those of Zygorhiza are much better developed and highly ornamented. Zygorhiza is slightly smaller than Dorudon atrox and has slightly more gracile forelimbs. Zygorhiza has a large narial process of the frontals like Dorudon atrox, but the medial maxillae of Zygorhiza touch both the nasals and the frontals. The posterior medial maxillae of members of the genus Dorudon contact only the nasals.
M. D. Uhen 2008Dorudon is much smaller than both Basilosaurus and Cynthiacetus. Dorudon also lacks the elongate trunk vertebrae of Basilosaurus. Dorudon can be distinguished from Zygorhiza by the lack of tiny denticles on the cingula of the upper premolars (Köhler and Fordyce, 1997). The premolars of Dorudon have relatively lower crowns than those of Chrysocetus.
M. D. Uhen 2013Members of the genus Dorudon are consid- erably larger than Saghacetus and Chrysocetus, and much smaller than members of the genera Basilosaurus or Cyn- thiacetus. Members of the genus Dorudon can be distin- guished from members of the genus Zygorhiza based on the lingual cingula on P2-3. While members of both gen- era have cingula on the mesial and distal ends of P2-3, those of Zygorhiza are much better developed and more highly ornamented. Dorudon is slightly larger and all com- parable skeletal elements are more robust than those in Zygorhiza.
