List Of Megafauna Discovered In Modern Times
The following is a list of megafauna discovered by science since the beginning of the 19th century (with their respective date of discovery). Some of these may have been known to native peoples or reported anecdotally but had not been generally acknowledged as confirmed by the scientific world, until conclusive evidence was obtained for formal studies. In other cases, certain animals were initially considered hoaxes – similar to the initial reception of mounted specimens of the duck-billed platypus ''Ornithorhynchus anatinus'' in late 18th-century Europe. The definition of megafauna varies, but this list includes some of the more notable examples.

Megafauna
In terrestrial zoology, the megafauna (from Greek μέγας ''megas'' "large" and New Latin ''fauna'' "animal life") comprises the large or giant animals of an area, habitat, or geological period, extinct and/or extant. The most common thresholds used are weight over see page 17 (i.e., having a mass comparable to or larger than a human) or over a tonne, (i.e., having a mass comparable to or larger than an ox). The first of these include many species not popularly thought of as overly large, and being the only few large animals left in a given range/area, such as white-tailed deer, Thomson's gazelle, and red kangaroo. In practice, the most common usage encountered in academic and popular writing describes land mammals roughly larger than a human that are not (solely) domesticated. The term is especially associated with the Pleistocene megafauna – the land animals often larger than their extant counterparts that are considered archetypical of the last ice age, such as mammoth ...

Bonobo
The bonobo (; ''Pan paniscus''), also historically called the pygmy chimpanzee and less often the dwarf chimpanzee or gracile chimpanzee, is an endangered great ape and one of the two species making up the genus '' Pan,'' the other being the common chimpanzee (''Pan troglodytes''). While bonobos are now recognized as a distinct species in their own right, they were initially thought to be a subspecies of chimpanzee (''Pan troglodytes)'' due to the physical similarities between the two species. Taxonomically, the members of the chimpanzee/bonobo subtribe Panina (composed entirely by the genus '' Pan'') are collectively termed ''panins''. The bonobo is distinguished by relatively long legs, pink lips, dark face, tail-tuft through adulthood, and parted long hair on its head. The bonobo is found in a area of the Congo Basin in the Democratic Republic of the Congo, Central Africa. The species is frugivorous and inhabits primary and secondary forests, including seasonally inundated sw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammalia
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 w ...

Giant Peccary
The collared peccary (''Dicotyles tajacu'') is a species of artiodactyl (even-toed) mammal in the family Tayassuidae found in North, Central, and South America. It is the only member of the genus ''Dicotyles''. They are commonly referred to as ''javelina, saíno'', or ''báquiro'', although these terms are also used to describe other species in the family. The species is also known as the musk hog. In Trinidad, it is colloquially known as ''quenk''. Taxonomy Although somewhat related to true Old World pigs, and frequently referred to as a pig, this species and the other peccaries are no longer classified in the pig family, Suidae. Although formerly classified in the genus ''Pecari'', studies in 2020 placed them in the genus ''Dicotyles'', based on an unequivocal type-species selection; these studies have been accepted by the American Society of Mammalogists. Currently, the IUCN still places them in the genus ''Pecari''. Description The collared peccary stands around tall at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumatran Muntjac
The Sumatran muntjac (''Muntiacus muntjak montanus'') is a subspecies of Indian muntjac in the deer family which can be the size of a large dog. It was discovered in 1914, but had not been sighted since 1930 until one was snared and freed from a hunter's snare in Kerinci Seblat National Park, Sumatra, Indonesia in 2002. Two other Sumatran muntjac have since been photographed in the park. The Sumatran muntjac was placed on the IUCN Red List in 2008, but was listed as Data Deficient, as taxonomic issues are still unresolved (it has been considered either a distinct species, ''M. montanus'', or a subspecies ''M. muntjak montanus'' of the common muntjac). The distribution of the taxon is also uncertain and may be more extensive than suggested. It is possible that some previous sightings of the common muntjac in Western Sumatra were the Sumatran muntjac.

Okapi
The okapi (; ''Okapia johnstoni''), also known as the forest giraffe, Congolese giraffe, or zebra giraffe, is an artiodactyl mammal that is endemic to the northeast Democratic Republic of the Congo in central Africa. It is the only species in the genus ''Okapia''. Although the okapi has striped markings reminiscent of zebras, it is most closely related to the giraffe. The okapi and the giraffe are the only living members of the family Giraffidae. The okapi stands about tall at the shoulder and has a typical body length around . Its weight ranges from . It has a long neck, and large, flexible ears. Its coat is a chocolate to reddish brown, much in contrast with the white horizontal stripes and rings on the legs, and white ankles. Male okapis have short, distinct horn-like protuberances on their heads called ossicones, less than in length. Females possess hair whorls, and ossicones are absent. Okapis are primarily diurnal, but may be active for a few hours in darkness. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Przewalski's Horse
Przewalski's horse (, , (Пржевальский ), ) (''Equus ferus przewalskii'' or ''Equus przewalskii''), also called the takhi, Mongolian wild horse or Dzungarian horse, is a rare and endangered horse originally native to the steppes of Central Asia. It is named after the Russian geographer and explorer Nikolay Przhevalsky. Once extinct in the wild, it has been reintroduced to its native habitat since the 1990s in Mongolia at the Khustain Nuruu National Park, Takhin Tal Nature Reserve, and Khomiin Tal, as well as several other locales in Central Asia and Eastern Europe. Several genetic characteristics of Przewalski's horse differ from what is seen in modern domestic horses, indicating neither is an ancestor of the other. For example, the Przewalski has 33 chromosome pairs, compared to 32 for the domestic horse. Their ancestral lineages split from a common ancestor between 38,000 and 160,000 years ago, long before the domestication of the horse. Przewalski's horse was long ...

Kabomani Tapir
The South American tapir (''Tapirus terrestris''), also commonly called the Brazilian tapir (from the Tupi ''tapi'ira''), the Amazonian tapir, the maned tapir, the lowland tapir, the ''anta'' (Portuguese), and ''la sachavaca'' (literally "bushcow", in mixed Quechua and Spanish), is one of the four recognized species in the tapir family (of the order '' Perissodactyla'', with the mountain tapir, the Malayan tapir, and the Baird's tapir). It is the largest surviving native terrestrial mammal in the Amazon. Most classification taxons also include ''Tapirus kabomani'' (also known as the little black tapir or kabomani tapir) as also belonging to the species ''Tapirus terrestris'' (Brazilian tapir), despite its questionable existence and the overall lack of information on its habits and distribution. The specific epithet derives from ''arabo kabomani'', the word for tapir in the local Paumarí language. The formal description of this tapir did not suggest a common name for the species. ...

Kouprey
The kouprey (''Bos sauveli''), also known as forest ox is a forest-dwelling, wild bovine species native to Southeast Asia. A young male was sent to the Paris Zoological Park in 1937 and was described by the French zoologist Achille Urbain who declared it the holotype. The kouprey has a tall, narrow body, long legs, a humped back and long horns. The kouprey has not been sighted since 1969–1970. A camera trapping survey in the region of these sightings failed to document it in 2011. It has been listed as Critically Endangered, and possibly extinct, on the IUCN Red List since 1996. The kouprey is the national animal of Cambodia and is also the nickname of their football team. Description The kouprey is believed to be a close relative of the aurochs (''Bos primigenius''), gaur (''B. gaurus''), and banteng (''B. javanicus''). A very large ungulate, the kouprey can approach similar sizes to the wild water buffalo (''Bubalus arnee''). These bovids measure along the head and bod ...

Baird's Tapir
The Baird's tapir (''Tapirus bairdii''), also known as the Central American tapir, is a species of tapir native to Mexico, Central America, and northwestern South America. It is the largest of the three species of tapir native to the Americas, as well as the largest native land mammal in both Central and South America. Names The Baird's tapir is named after the American naturalist Spencer Fullerton Baird, who traveled to Mexico in 1843 and observed the animals. However, the species was first documented by another American naturalist, W. T. White. Like the other American tapirs (the mountain tapir and the South American tapir), the Baird's tapir is commonly called ''danta'' by people in all areas. In the regions around Oaxaca and Veracruz, it is referred to as the ''anteburro''. Panamanians, and Colombians call it ''macho de monte'', and in Belize, where the Baird's tapir is the national animal, it is known as the mountain cow. In Mexico, it is called ''tzemen'' in Tzeltal; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anecdote
An anecdote is "a story with a point", such as to communicate an abstract idea about a person, place, or thing through the concrete details of a short narrative or to characterize by delineating a specific quirk or trait. Occasionally humorous, anecdotes differ from jokes because their primary purpose is not simply to provoke laughter but to reveal a truth more general than the brief tale itself. Anecdotes may be real or fictional; the anecdotal digression is a common feature of literary works and even oral anecdotes typically involve subtle exaggeration and dramatic shape designed to entertain the listener. An anecdote is always presented as the recounting of a real incident involving actual people and usually in an identifiable place. In the words of Jürgen Hein, they exhibit "a special realism" and "a claimed historical dimension" . Etymology and usage The word ''anecdote'' (in Greek: ἀνέκδοτον "unpublished", literally "not given out") comes from Procopius of ...

Mountain Tapir
The mountain tapir, also known as the Andean tapir or woolly tapir (''Tapirus pinchaque'') is the smallest of the four widely recognized species of tapir. It is the only one to live outside of tropical rainforests in the wild. It is most easily distinguished from other tapirs by its thick woolly coat and white lips. The species name comes from the term ''"La Pinchaque"'', an imaginary beast said to inhabit the same regions as the mountain tapir. Description Mountain tapirs are black or very dark brown, with occasional pale hairs flecked in amongst the darker fur. The fur becomes noticeably paler on the underside, around the anal region, and on the cheeks. A distinct white band runs around the lips, although it may vary in extent, and there are usually also white bands along the upper surface of the ears. In adults, the rump has paired patches of bare skin, which may help to indicate sexual maturity. The eyes are initially blue, but change to a pale brown as the animal ages. Unl ...
