Kwanzacetus

Kwanzacetus is an extinct genus of iniid, a member of the river dolphin family Iniidae, that inhabited the waters off what is now Angola during the Miocene epoch. The genus contains a single described species, Kwanzacetus khoisani, which was named in 2018 on the basis of fossil material from the Angolan coast. The Paleobiology Database dates the species to between the Tortonian and Messinian ages, roughly 11.6 million to 5.3 million years ago. Because the living members of its family are confined to the river basins of South America, Kwanzacetus is evidence that iniids once ranged across the South Atlantic, including the coast of southwestern Africa.
