Diagnosis
ReferenceDiagnosis
S. Bajpai and J. G. M. Thewissen 2014Kharodacetus is a large protocetid, with large premolars and molars, larger than any previously described Indo-Pakistani protocetid (Figure 2). Kharodacetus has a flat supraorbital shield with large orbits, similar to all other protocetids and different from pakicetids, ambulocetids and remingtonocetids. Kharodacetus has a long, relatively broad snout (snout is narrower in Gaviacetus and Makaracetus, broader in Takracetus), its orbit is high above the palate (unlike Indocetus), the premolars are large and robust (unlike Rodhocetus, Qaisracetus, Makaracetus and Gaviacetus). The molars have a large protocone (unlike Babiacetus) and a large metacone (unlike Maiacetus), and are, relative to P4, longer than in other protocetids (Figure 2).
