|---|---|---|
| S. Bajpai and J. G. M. Thewissen 2014 | Dhedacetus is a medium-sized protocetid, with premolars and molars similar in size to the larger protocetids described before from the Indian continent (namely Babiacetus, Rodhocetus, Maiacetus). As in Kharodacetus, Dhedacetus has a long, relatively broad snout (snout is narrower in Gaviacetus and Makaracetus, broader in Takracetus). In Dhedacetus, the orbit is high above the palate (unlike Indocetus and Babiacetus), the premolars are large (unlike Rodhocetus, Qaisracetus, Makaracetus, and Gaviacetus) and gracile (unlike Kharodacetus). The molars have a large protocone (unlike Babiacetus) and metacone (unlike Maiacetus). Kharodacetus is similar to all other protocetids and differs from pakicetids, ambulocetids and remingtonocetids by having a flat supraorbital shield with large orbits. It differs from basilosaurids in retaining M3. |
