Diceros (Greek: "two" (dio), "horn" (keratos)[1]) is a genus of rhinoceros containing the extant black rhinoceros (Diceros bicornis) and several extinct species.[2]

Taxonomy

Diceros is more closely related to the genus

Dicerotini (also spelled Diceroti) or subtribe Dicerotina.[3]

Diceros has been suggested by some authors to have branched off from an early species of Ceratotherium, specifically C. neumayri,[4] which has also been assigned to Diceros in some studies.[3] However, other authors have disputed the close relationship between Diceros and "C". neumayri.[3]

The oldest species assigned to the genus is "Diceros" australis from the Early Miocene of Namibia,[5] dating to around 17-18 million years ago.[6] It is only known from fragmentary remains, and its assignment to the genus, and even to Dicerotini have been questioned by other authors.[3] Other species assigned to the genus include Diceros praecox from the Late Miocene (from about 7 million years ago) and the Pliocene of Sub-Saharan Africa.[6] D. praecox has been suggested by some authors to be the ancestor of the modern D. bicornis.[7] Diceros primaevus is known from the Late Miocene (c. 12-10 million years ago) of Algeria.[6][3] Diceros douariensis is known from the Late Miocene of Tunisia and possibly Ethiopia.[6][3] Some authors have assigned this species to Ceratotherium.[8] The species Diceros gansuensis has been reported from the Late Miocene of China,[9] dating to around 10 million years ago.[6] The earliest remains assigned to the modern black rhinoceros are known the Late Miocene (around 7 million years ago) of East Africa.[6]
