White Rhinos
The white rhinoceros, white rhino or square-lipped rhinoceros (''Ceratotherium simum'') is the largest extant species of rhinoceros. It has a wide mouth used for grazing and is the most social of all rhino species. The white rhinoceros consists of two subspecies: the southern white rhinoceros, with an estimated 19,682–21,077 wild-living animals in the year 2015, and the much rarer northern white rhinoceros. The northern subspecies has very few remaining individuals, with only two confirmed left in 2018 (two females: Fatu, 18 and Najin, 29), both in captivity. Sudan, the world's last known male Northern white rhinoceros, died in Kenya on 19 March 2018 at age 45. Naming A popular albeit widely discredited theory of the origins of the name "white rhinoceros" is a mistranslation from Dutch to English. The English word "white" is said to have been derived by mistranslation of the Dutch word "wijd", which means "wide" in English. The word "wide" refers to the width of the rhinocer ...

Kruger National Park
Kruger National Park is a South African National Park and one of the largest game reserves in Africa. It covers an area of in the provinces of Limpopo and Mpumalanga in northeastern South Africa, and extends from north to south and from east to west. The administrative headquarters are in Skukuza. Areas of the park were first protected by the government of the South African Republic in 1898, and it became South Africa's first national park in 1926. To the west and south of the Kruger National Park are the two South African provinces of Limpopo and Mpumalanga, respectively. To the north is Zimbabwe, and to the east is Mozambique. It is now part of the Great Limpopo Transfrontier Park, a peace park that links Kruger National Park with the Gonarezhou National Park in Zimbabwe, and with the Limpopo National Park in Mozambique. The park is part of the Kruger to Canyons Biosphere, an area designated by the United Nations Educational, Scientific and Cultural Organization (UNES ...

John Edward Gray
John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Big Game Of Africa (1910) - Black & White Rhinos
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Ceratotherium Mauritanicum
''Ceratotherium mauritanicum'' is a species of fossil African rhinoceros found in the Late Pliocene to earliest Holocene of Morocco, Tunisia, and Algeria. Slightly older fossils from the Pliocene of eastern Africa were also proposed to belong to this species, but it has been considered to belong to a somewhat more primitive species, ''Ceratotherium efficax''. A 2020 study considers ''C. efficax'' to be the same species as ''C. mauritanicum'', however. Evolution The phylogenetic position of ''C. mauritanicum'' is somewhat disputed. One model see it as to be located in a direct line of ancestry between the primitive ''Ceratotherium neumayri'' and the living white rhinoceros (''Ceratotherium simum''). Alternatively it was proposed to be the descendant of ''Ceratotherium efficax'' and an extinct sister taxon to '' C. simum''. It retained primitive characters contemporaneously to the more progressive evolution of the genus '' Ceratotherium'' in eastern and southern Africa. Distribu ...

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.

Makapansgat
Makapansgat () (or Makapan Valley World Heritage Site) is an archaeological location within the Makapansgat and Zwartkrans Valleys, northeast of Mokopane in Limpopo province, South Africa. It is an important palaeontological site, with the local limeworks containing ''Australopithecus''-bearing deposits dating to between 3.0 and 2.6 million years BP. The whole Makapan Valley has been declared a South African Heritage Site. Makapansgat belongs to the Cradle of Humankind. Makapansgat Valley sites Makapansgat limeworks This is the oldest of the cave sites in the Makapansgat valley, spanning an age of greater than 4.0 million years until perhaps 1.6 million years ago. This site has yielded many thousands of fossil bones, amongst which were found remains of the gracile australopithecine ''Australopithecus africanus''. The ''A. africanus'' fossils are suggested to date to between 2.85 and 2.58 million years ago based on palaeomagnetism by Andy Herries (La Trobe University, Australi ...

Diceros Bicornis
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] |
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.

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Langebaanweg
Langebaanweg is a town on the southwest coast of South Africa, in Western Cape Province. It is the location of the air force base AFB Langebaanweg. Langebaanweg has been an important mining center, with its mai minerals consisting of phosphorites, primarily calcium phosphate. The mining uncovered fossils dating from the late Miocene and early Pliocene, approximately 5 million years ago. Fossil species found there include invertebrates and also a type of rhinoceros, as well as a mousebird and a diving petrel. The West Coast Fossil Park includes displays of fossils found in a former phosphate mine. Brett Hendey, formally of the Iziko South African Museum, documented the significance of the Langebaanweg fossil sites.
