Taxonomy
''Diceros'' is generally believed to have branched off from an early species of '' Ceratotherium'', specifically '' C. neumayri''. However an even older species than ''C. neumayri'' from the Miocene has been placed in ''Diceros'' ''( D.australis)''. '' D. praecox'' is considered the direct ancestor of the black rhinoceros.References
