Parapontoporia is an extinct genus of dolphin that lived off the Pacific coast of North America from the Late Miocene until the genus' extinction during the Pliocene.[1][2] It is related to the baiji.[3] Fossils have been found in California (Tulare Formation) and Mexico (Almejas Formation). The Tulare Formation is predominately freshwater, which suggests Parapontoporia may have been tolerant of both salt and fresh water.[3]
