Biology:Pomatodelphis
Pomatodelphis is an extinct genus of river dolphin from Middle Miocene marine deposits in Alabama, Maryland, Florida, Brazil, Germany, and France.[1][2][3][4][5]
Etymology
Pomatodelphis may be a typo for potamodelphis ("river dolphin")[6] from potamo-, "river", and δελφίς, delphis "dolphin".
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.[7]
