Dicerorhinus (Greek: "two" (dio), "horn" (keratos), "nose" (rhinos) ^[1] )^{[ citation needed ]} 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

Species provisionally considered valid include:

• †Dicerorhinus fusuiensis ^{[4] [5]} originally described as Rhinocerosfusuiensis ^[6] Early Pleistocene, South China.
• †Dicerorhinus gwebinensisZin-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 (synonym of Stephanorhinus kirchbergensis )
• Dicerorhinus hemitoechus
• Dicerorhinus etruscus
• Dicerorhinus yunchuchenensis
• Dicerorhinus jeanvireti
• Dicerorhinus choukoutienensis (synonym of Stephanorhinus kirchbergensis)
• Dicerorhinus orientalis (synonym of Stephanorhinus kirchbergensis)
• Dicerorhinus nipponicus ^[9] (synonym of Stephanorhinus kirchbergensis)

Transferred to Dihoplus ^[3]

• 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
