Dihoplus
Dihoplus is an extinct genus of rhinoceros that lived in Eurasia from the Late Miocene to Early Pleistocene. They were moderately large rhinoceros, with two horns and large, thick nasal bones. Members of "Dihoplus" were long placed in "Dicerorhinus" (which contains the living Sumatran rhinoceros). Sometimes these species are placed in the related "Stephanorhinus". The genus is now generally considered distinct, though there is still debate as to which species should be included; for example, Deng (2011) listed Merck's rhinoceros "(Stephanorhinus kirchbergensis)" under "Dihoplus".
