Aceratheriinae
Aceratheriinae is an extinct subfamily of rhinoceros endemic to Asia, Africa, Europe, and North America, from the Oligocene through the Pliocene. It lived from 33.9 to 3.4 mya, existing for approximately . Taxonomy Aceratheriinae was named by Dollo (1885). It was assigned to Rhinocerotida by Codrea (1992); and to Rhinocerotidae by Prothero (1998), Antoine et al. (2000), Kaya and Heissig (2001), Sach and Heizmann (2001) and Deng (2005).P.-O. Antoine, C.

Aceratherium
''Aceratherium'' (Greek: "without (a) horn" (keratos), "beast" (therion)) was a genus of rhinoceros of the subfamily Aceratheriinae that lived in Eurasia during the Miocene. Taxonomy ''Aceratherium'' was coined by Kaup (1832) for ''"Rhinoceros" incisivum'' Cuvier, 1822 on the basis of the similarity of two skulls from Eppelsheim, Germany to the holotype incisor tooth from Weisenau in dental structure. However, the tooth from Weisenau has been recognized as belonging to a member of Teleoceratini, although the name ''Aceratherium'' has been widely used for the Eppelsheim skulls. Traditionally, many species have been referred to ''Aceratherium'' on the basis of them being hornless, turning the genus into a wastebasket. Revisions over the years have removed most species to the point that there are now only three valid species generally recognized (''A. incisivum'', ''A. depereti'', and ''A. porpani'').

Aphelops
''Aphelops'' (Greek: "smooth" (apheles), "face" (ops), in a reference of lacking a horn) is an extinct genus of hornless rhinoceros endemic to North America. It lived from the Middle Miocene to the early Pliocene, during which it was a common component of North American mammalian faunas along with '' Teleoceras''. Description On the basis of skull size, the largest species of ''Aphelops'' is ''A. mutilus'' (which is the largest North American rhinoceros) and the smallest is the type species ''A. megalodus''. ''A. mutilus'' has been estimated to have weighed , and ''A. malacorhinus'' has been estimated at . ''Aphelops'' can be distinguished by other members of the Aceratheriinae by two traits: the arched top of the skull, and the long diastema (gap) between the second incisor (lower tusk) and first premolar. Many other aspects of its anatomy are typical of aceratheriines, including: the absence of a horn on the broad, unfused nasal bones; the reduced premaxilla and lost f ...

Alicornops
''Alicornops'' is an extinct genus of rhinoceros belonging to the subfamily Aceratheriinae. It lived in Eurasia during the Miocene and Pliocene. Four species are known. Two of them, ''Alicornops complanatum'' and ''Alicornops laogouense'' were described recently from the Siwaliks of Pakistan Pakistan ( ur, ), officially the Islamic Republic of Pakistan ( ur, , label=none), is a country in South Asia. It is the world's List of countries and dependencies by population, fifth-most populous country, with a population of almost 24 .... The type species ''Alicornops simorrense'' was a relatively small aceratheriine with a small horn, short tridactyl legs and strongly curved lower incisors.

Floridaceras
''Floridaceras'' is an extinct genus of Rhinocerotidae (rhinoceros) of the Miocene epoch (early Hemingfordian), endemic to North America, living from around ~20.6–16.3 Ma, existing for approximately . Taxonomy ''Floridaceras'' was named by Wood (1964). Its type is ''Floridaceras whitei''. It was assigned to Rhinocerotidae by Wood (1964) and Carroll (1988); and to Aceratheriinae by Prothero (1998). Fossil distribution The only site known is the Thomas Farm Site in Gilchrist County, Florida, ~20.6—16.3 Ma. Description ''Floridaceras'' was of unusually large size for a rhinoceros of the Hemingfordian. It would have been roughly comparable to a black rhinoceros in size, much larger than contemporaries such as the ''Menoceras ''Menoceras'' ("Crescent Horns") is a genus of extinct, small rhinoceros endemic to most of southern North America and ranged as far south as Panama during the early Miocene epoch.

Taxonomy
Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Taxonomy is different from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brachypotherium
''Brachypotherium'' is an extinct genus of rhinoceros that lived in Eurasia and Africa during the Miocene. A first upper decidual molar referrable to ''Brachypotherium brachypus'' was found during gold mining in New Caledonia during the 19th century, being misidentified as a species of marsupial known as ''Zygomaturus.'' However, rhinoceros were never native to New Caledonia, and the tooth was probably used as jewelry by a French convict deported there. Many species of ''Brachypotherium'' have been described. Some species have moved to other genera, such as ''B. aurelianense'' being transferred to ''Diaceratherium''. The genus was widespread during the Early and Middle Miocene, before heading into a decline. They went extinct in Eurasia Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia.
