Paradiceros
''Paradiceros'' is an extinct genus of rhinoceros that lived in east Africa during the Late Miocene, between 10.5 and 9 million years ago. ''Paradiceros'' was a relatively small species once believed to be closely allied to ''Diceros''. It was a browser and had very short legs, though not as short as some of the more primitive species like ''Chilotherium ''Chilotherium'' is an extinct genus of rhinoceros endemic to Eurasia during the Miocene through Pliocene living for 13.7—3.4 mya, existing for approximately ..

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ...

Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of life The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') are the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally, chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 to 8 million years ago, that is, during the Late Miocene.

Diceros
''Diceros'' (Greek: "two" (dio), "horn" (keratos)) is a genus of rhinoceros containing the living black rhinoceros ''(Diceros bicornis)'' and at least one extinct species. Taxonomy ''Diceros'' is generally believed to have branched off from an early species of ''Ceratotherium ''Ceratotherium'' (Greek: "horn" (keratos), "beast" (therion)) is a genus of the family Rhinocerotidae, consisting of a single extant species, the white rhinoceros The white rhinoceros, white rhino or square-lipped rhinoceros (''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.

Chilotherium
''Chilotherium'' is an extinct genus of rhinoceros endemic to Eurasia during the Miocene through Pliocene living for 13.7—3.4 mya, existing for approximately .. Retrieved 19 May 2013. Description It was a large, robust animal reaching 1.5-1.8 m in height and a weight between 1 and 2.5 tons, depending on the species. Both sexes are hornless. The lower jaw has a widened symphysial part and large tusk-like second incisors separated by a broad diastema. The dental formula is . The limbs are very short and the body stout; the feet are tridactyl with diverging metapodials. Studying ''C. wimani'', found a significant sexual dimorphism in the tusks and mandible, most notably the length of the tusks in males. argued that some features in ''Chilotherium'', such as second incisors, mandible, cheek-teeth and other cranial features, are plesiomorphic, while some features in the tusks are apomorphic: the dorsal surface of the tusks in primitive species is turned latero-dorsally in ...

Miocene Mammals Of Africa
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ...
