Black Rhinoceros
The black rhinoceros, black rhino or hook-lipped rhinoceros (''Diceros bicornis'') is a species of rhinoceros, native to eastern and southern Africa including Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Eswatini, Tanzania, Zambia, and Zimbabwe. Although the rhinoceros is referred to as ''black'', its colours vary from brown to grey. The other African rhinoceros is the white rhinoceros (''Ceratotherium simum''). The word "white" in the name "white rhinoceros" is often said to be a misinterpretation of the Afrikaans word ' (Dutch ') meaning wide, referring to its square upper lip, as opposed to the pointed or hooked lip of the black rhinoceros. These species are now sometimes referred to as the square-lipped (for white) or hook-lipped (for black) rhinoceros. The species overall is classified as critically endangered (even though the south-western black rhinoceros is classified as near threatened). Three subspecies have been declared extinct, including the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhinoceros
A rhinoceros (; ; ), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae. (It can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea.) Two of the extant species are native to Africa, and three to South and Southeast Asia. Rhinoceroses are some of the largest remaining megafauna: all weigh at least one tonne in adulthood. They have a herbivorous diet, small brains (400–600 g) for mammals of their size, one or two horns, and a thick (1.5–5 cm), protective skin formed from layers of collagen positioned in a lattice structure. They generally eat leafy material, although their ability to ferment food in their hindgut allows them to subsist on more fibrous plant matter when necessary. Unlike other perissodactyls, the two African species of rhinoceros lack teeth at the front of their mouths; they rely instead on their lips to pl ...

Diceros Praecox
''Diceros praecox'' is an extinct species of rhinoceros that lived in Africa during the Pliocene, around 4 million years ago. It is considered the direct ancestor of the living black rhinoceros ''(Diceros bicornis)''. Taxonomy ''Diceros praecox'' has for many years been classified as ''Ceratotherium praecox'', however the original material describing the species has been shown to be closer to the black rhinoceros in its skull morphology. Other material showing greater similarities with the white rhinoceros are considered to belong to a different species, ''Ceratotherium mauritanicum''. ''D. praecox'' likely arose from ''Ceratotherium neumayri ''Ceratotherium neumayri'' is a fossil species of rhinoceros from the eastern Mediterranean, in the Anatolia region in modern Turkey, dating to the late Miocene.

Ceratotherium Neumayri
''Ceratotherium neumayri'' is a fossil species of rhinoceros from the eastern Mediterranean, in the Anatolia region in modern Turkey, dating to the late Miocene. It is the likely ancestor of both the white rhinoceros and black rhinoceros lineages of Africa. A well-preserved sample fossil of the species, which is believed to have died of high temperatures during a volcanic eruption, has been found in Gülşehir Gülşehir, formerly Aravissos and Arapsun, ancient Zoropassos (Ancient Greek: ''Ζωρόπασος''), is a town and district of Nevşehir Province in the Central Anatolia region of Turkey, in the vicinity of the Fairy Chimney valley of Göreme. ..., Turkey on 2012.

Mammal Genera
There are currently 1,258 genera, 156 families, 27 orders, and around 5,937 recognized living species of mammal. Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families. The taxonomy represented here is a compilation of the most logical and up-to-date information on mammalian taxonomy from many sources, the main ones being ''Handbook of the Mammals of the World'' series and ''Mammal Species of the World''.

Mammal Genera With One Living Species
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

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.
