Species

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 in the Mid to Late Pliocene of Northern Indochina and South China.[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 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:
