Classification: Chordata, Mammalia, Cetacea, Archaeoceti, Protocetidae.
Species: B. indicus (type), B. mishrai.
Size: Uncertain due to lack of post cranial remains.
Known locations: India - Harudi Formation, and Pakistan - Drazinda Formation.
Time period: Lutetian to Bartonian of the Eocene.
Fossil representation: Remains of at least 3 individuals, though only of skulls, mandibles, dentaries and teeth.
Babiacetus was a member of the Archaeoceti, a group of primitive whales that also includes genera such as Basilosaurus, Dorudon, Protocetus and Zygorhiza. Babiacetus seems to have lived more during the middle Eocene, though since the genus is currently only known for cranial remains, we do not know how well developed the actual body was for an aquatic lifestyle. Babiacetus is noted for having large teeth that were around three and five centimetres long along the base of the crown. The large size and spacing of these teeth indicate that Babiacetus was a predator of large to mid-sized marine organisms, including fish and possibly other marine mammals. The auditory bulla of Babiacetus is also noted as being narrower than that of Rodhocetus.
