Etymology
editPomatodelphis may be a typo for potamodelphis ("river dolphin")[2] from potamo-, "river", and δελφίς, delphis "dolphin".
Classification
editPomatodelphis 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.[3]

- Citronelle Formation (Hemphillian), Alabama
- Solimões Formation (Huayquerian), Brazil
- Marks Head, Peace River and Statenhead Formations, Florida
