Pomatodelphis is an extinct genus of river dolphin from Middle Miocene marine deposits in Alabama, Florida, Brazil, Germany and France.[1]
Classification
Pomatodelphis belongs to the platanistid subfamily Pomatodelphininae, which is distinguished from the South Asian river dolphin in having a flattened rostrum, a transversely expanded posterior end of the premaxilla, an eye and bony orbit of normal size (not atrophied), and nasal bones not reduced in size but wide transversely. A close relative of Pomatodelphis is Prepomatodelphis from marine deposits in Austria. Three species are known, P. inaequalis, P. bobengi, and P. stenorhynchus.[2]
