Dicerorhinus

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 previously placed in this genus probably belong elsewhere''. ''

Taxonomy
Species provisionally considered valid include:
 * †Dicerorhinus fusuiensis  originally described as Rhinoceros fusuiensis  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. Some authors have considered the skull not distinguishable from that of D. sumatrensis.

Historically, Dicerorhinus was a wastebasket taxon. Revisions by several authors over the years have removed many species:
