"A cladistic analysis of the family Rhinocerotidae encompassing 45 taxa and 72 characters (referred to craniomandibular [20], dental [26], and postcranial [26] features), and using Hyrachyus and two subfamilies of Hyracodontidae as outgroups, discovered 104 equally parsimonious cladograms. When the analysis was run with Hyrachyus as the only outgroup (removing the hyracodontid subfamilies), only six equally parsimonious trees were discovered. The discovered trees of the two analyses are compared, which suggests a reinterpretation of the phylogenetic relationships within the Rhinocerotidae. The subfamilies Diceratheriinae and Menoceratinae are not supported, as the genera included within them appear as a paraphyletic group. Phylogenies of the subfamilies Rhinocerotinae and Aceratheriinae are questioned. Within the former, the elasmotheriines are separated into two groups: a new subtribe, Iranotheriina, is proposed, while Elasmotherium and Ninxiatherium appear more closely related to Stephanorhinus and Coelodonta. The content of the subtribe Rhinocerotina is revised. The tribe Teleoceratini is removed from the Rhinocerotinae and included within the subfamily Aceratheriinae. A new aceratherine tribe, Alicornopini, is proposed for Alicornops, Peraceras, and Chilotheridium. The analysis indirectly supports some synonymies previously suggested, such as 'Begertherium' = Hispanotherium, and 'Dicerorhinus' schleiermacheri = Lartetotherium schleiermacheri"--P. [1].
