Dicerorhinus (Greek: "two" (dio), "horn" (keratos), "nose" (rhinos)) is a genus of the family Rhinocerotidae, consisting of a single extant species, the two-horned Sumatran rhinoceros (D. sumatrensis), and several extinct species. The genus likely originated in the Mid to Late Pliocene of Northern Indochina and South China. Many species attributed to the genus probably actually belong in Stephanorhinus. Taxonomy Historically, Dicerorhinus was a wastebasket taxon. Revisions by several authors over the years have removed many species: Transferred to Stephanorhinus Dicerorhinus merckii Dicerorhinus hemitoechus Dicerorhinus etruscus Dicerorhinus yunchuchenensis Dicerorhinus jeanvireti Dicerorhinus choukoutienensis (synonym of Merck's rhinoceros) Dicerorhinus orientalis (synonym of Merck's rhinoceros) Dicerorhinus nipponicus Transferred to Dihoplus Dicerorhinus megarhinus Dicerorhinus schleiermacheri Dicerorhinus ringstroemi Transferred to Caementodon Dicerorhinus caucasicus Transferred to Lartetotherium Dicerorhinus sansaniensis Transferred to Rusingaceros Dicerorhinus leakeyi References Groves, Colin P., and Fred Kurt (1972).
