Dilophodelphis is an extinct genus of river dolphin from Early Miocene (Burdigalian) marine deposits in Oregon. The type species, Dilophodelphis fordycei, was named in 2017.^[1]

Biology and description

Dilophodelphis is distinguished from other extinct relatives of the South Asian river dolphin in having enlarged supraorbital crests resembling a twin mountain arrangement, quite similar to the crests of the theropod dinosaur Dilophosaurus.^[1]
