Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. D. Gingerich et al. 2022 | Antaecetus has the distinctive pachyosteosclerotic vertebrae of pachycetine basilosaurids but differs from Pachycetus in being smaller and having a notably small cranium. The teeth are more gracile, with smooth rather than crenulated enamel. The first upper premolar, P1, differs from that in Pachycetus in being single-rooted. Posterior upper premolars differ from those of Pachycetus in having three rather than four accessory cusps or denticles flanking the central cusp anteriorly and posteriorly. Upper molars differ in retaining a distinct posteromedial expansion in the position formerly occupied by the protocone. |
