Dicerorhinus

Dicerorhinus (Greek: "two" (dio), "horn" (keratos), "nose" (rhinos)<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>)Template:Source 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.<ref>Template:Cite journal</ref> Many species previously placed in this genus probably belong elsewhere.<ref name="tong" />

Taxonomy

Species provisionally considered valid include:

• †Dicerorhinus fusuiensis<ref name=":0">Template:Cite journal</ref><ref>Template:Cite journal</ref> originally described as Rhinoceros fusuiensis<ref>Template:Cite journal</ref> 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.<ref>Template:Cite journal</ref> Some authors have considered the skull not distinguishable from that of D. sumatrensis.<ref>Template:Cite journal</ref>

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