Dicerorhinus (Greek: "two" (dio), "horn" (keratos), "nose" (rhinos)[1]) 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 from the Late Miocene of central Myanmar.[2] Many species previously placed in this genus probably belong elsewhere.[3]

Taxonomy
editSpecies provisionally considered valid include:
- †Dicerorhinus fusuiensis[4][5] originally described as Rhinoceros fusuiensis[6] Early Pleistocene, South China.
- †Dicerorhinus gwebinensis Zin-Maung-Maung-Thein et al., 2008 Known from a skull of Pliocene-Early Pleistocene age found in Myanmar.[7] Some authors have considered the skull not distinguishable from that of D. sumatrensis.[8]
Historically, Dicerorhinus was a wastebasket taxon. Revisions by several authors over the years have removed many species:
Transferred to Stephanorhinus[3]
- 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[9]
- Dicerorhinus megarhinus
- Dicerorhinus schleiermacheri
- Dicerorhinus ringstroemi
Transferred to Caementodon
- Dicerorhinus caucasicus[10]
Transferred to Lartetotherium
- Dicerorhinus sansaniensis
- Dicerorhinus cixianensis Chen and Wu, 1976[11]
Transferred to Rusingaceros
- Dicerorhinus leakeyi
