Acinonyx
''Acinonyx'' is a genus within the Felidae family. The only living species of the genus, the cheetah (''A. jubatus''), lives in open grasslands of Africa and Asia. Several fossil remains of cheetah-like cats were excavated that date to the late Pliocene and Middle Pleistocene. These cats occurred in Africa, parts of Europe and Asia about 10,000 years ago. Several similar species classified in the genus '' Miracinonyx'' lived in North America at the same time; these may have been more closely related to the genus '' Puma''. Taxonomy ''Acinonyx'' was proposed by Joshua Brookes in 1828. Between the late 18th century and the early 20th century, the following ''Acinonyx'' species and subspecies were described: * ''Felis jubatus'' by Johann Christian Daniel von Schreber in 1777 was based on earlier descriptions by Comte de Buffon and Thomas Pennant. ** ''Felis venatica'' by Griffith in 1821 was based on a sketch of a cheetah from India. ** ''Cynailurus soemmeringi'' by Fitzi ...

Cheetah
The cheetah (''Acinonyx jubatus'') is a large Felidae, cat and the Fastest animals, fastest land animal. It has a tawny to creamy white or pale buff fur that is marked with evenly spaced, solid black spots. The head is small and rounded, with a short snout and black tear-like facial streaks. It reaches at the shoulder, and the head-and-body length is between . Adults weigh between . The cheetah is capable of running at ; it has evolved specialized adaptations for speed, including a light build, long thin legs and a long tail. The cheetah was first Species description, described in the late 18th century. Four subspecies are recognised today that are native to Africa and central Iran. An African subspecies was Cheetah reintroduction in India, introduced to India in 2022. It is now distributed mainly in small, fragmented populations in northwestern, East Africa, eastern and southern Africa and central Iran. It lives in a variety of habitats such as savannahs in the Serengeti, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acinonyx Pardinensis
''Acinonyx pardinensis'', sometimes called the giant cheetah, is an extinct felid species belonging to the genus ''Acinonyx'', closely related to the cheetah, native to Eurasia from Late Pliocene to Early Pleistocene epoch, from 2.8 to 1.4 ma. It was substantially larger than the living cheetah. Description ''Acinonyx pardinensis'' was roughly twice the size of today's cheetahs, weighing around , though '' A. pleistocaenicus'' was much larger. The morphology of the skull shows some similarities with those of pantherine cats and is not as short and deep as that of the modern cheetah. The teeth greatly resemble that of a modern cheetah. The limb bones, like those of a modern cheetah, were elongate relative to the animal's body size. The lumbar vertebrae were also elongate, suggesting the back was flexible. Compared to living cheetahs, the femur is more straight and the fibia is more robust and not fused to the tibia. The humerus is also more robust. Classification ''Acinonyx pa ...

Acinonyx Jubatus Venaticus
The Asiatic cheetah (''Acinonyx jubatus venaticus'') is a critically endangered cheetah subspecies currently only surviving in Iran. Its range once spread from the Arabian Peninsula and the Near East to the Caspian region, Transcaucasus, Kyzylkum Desert and northern South Asia, but was extirpated in these regions during the 20th century. The Asiatic cheetah diverged from the cheetah population in Africa between 32,000 and 67,000 years ago. The Asiatic cheetah survives in protected areas in the eastern-central arid region of Iran, where the human population density is very low. Between December 2011 and November 2013, 84 individuals were sighted in 14 different protected areas, and 82 individuals were identified from camera trap photographs. In December 2017, fewer than 50 individuals were thought to be remaining in three subpopulations that are scattered over in Iran's central plateau. As of April 2024, five Asiatic cheetahs reside in a breeding facility in the country. Tax ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acinonyx Pleistocaenicus
''Acinonyx pleistocaenicus'' is an extinct felid species belonging to the genus ''Acinonyx'', native to Eurasia from the Early Pleistocene to Middle Pleistocene, from 1.3 to 0.6 million years ago. This species was larger than ''Acinonyx pardinensis''. Taxonomy Classification Originally described as ''Cynailurus pleistocaenicus'', several studies have since considered ''Acinonyx pleistocaenicus'' as a subspecies of ''Acinonyx pardinensis''. However, Jiangzuo et al. (2024) suggested that its cranial and dental anatomy have more distinguishing features and resemble more of modern cheetahs based on new specimens, classifying ''A. pleistocaenicus'' and ''A. pardinensis'' as separate species. Evolution ''Acinonyx pleistocaenicus'' may have evolved from ''A. pardinensis'' in Eurasia during the Early Pleistocene. During the Middle Pleistocene, ''A. pleistocaenicus'' was replaced by ''Acinonyx intermedius''. In spite of its similarity to ''A. intermedius'' and modern cheetah, ''A. ...

Miracinonyx
''Miracinonyx'' (colloquially known as the "American cheetah" or the "New World cheetah") is an extinct genus of felids belonging to the subfamily Felinae that was endemic to North America from the Pleistocene epoch (about 2.5 million to 16,000 years ago) and morphologically similar to the modern cheetah (''Acinonyx jubatus''), although its apparent similar ecological niches have been considered questionable due to anatomical morphologies of the former that would have limited its ability to act as a specialized pursuit predator. The genus was originally known from fragments of skeletons, but nearly complete skeletons have been recovered from Natural Trap Cave in northern Wyoming. The two species commonly identified are ''M. inexpectatus'' and ''M. trumani''. Sometimes, a third species, ''M. studeri'', is included, but it is more often listed as a junior synonym of ''M. inexpectatus''. ''M. inexpectatus'' ranged from the Blancan to Irvingtonian ages of North America while ''M. tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acinonyx Aicha
''Acinonyx aicha'' is an extinct felid species belonging to the genus ''Acinonyx''. It was first described in 1997 based on fossils from the Pliocene of Morocco. Discovery and naming ''Acinonyx aicha'' was discovered in the Ahl al Oughlam site in Morocco, from the late Pliocene. It is known from the holotype AaO-1456 which is a complete and disfigured skull, as well as maxilla and some teeth. The specific name is derived from a cheetah called Ayesha from TinTin, specifically from The Red Sea Sharks ''The Red Sea Sharks'' () is the nineteenth volume of ''The Adventures of Tintin'', the comic series by Belgian cartoonist Hergé. The story was initially serialised weekly in Belgium's ''Tintin'' magazine from October 1956 to January 1958 b ...

Acinonyx Intermedius
''Acinonyx intermedius'' is a fossil species of felid belonging to the cheetah genus ''Acinonyx.'' It has been found in Olduvai, Tanzania and in cave sites in South Africa. It was described by paleontologist Thenius in 1954. It is sometimes considered part of '' Acinonyx pardinensis'' (where that species is considered a macrospecies) as ''A. p. intermedius''. References intermedius The vastus intermedius () (Cruraeus) arises from the front and lateral surfaces of the body of the femur in its upper two-thirds, sitting under the rectus femoris muscle and from the lower part of the lateral intermuscular septum.

Felidae
Felidae ( ) is the Family (biology), family of mammals in the Order (biology), order Carnivora colloquially referred to as cats. A member of this family is also called a felid ( ). The 41 extant taxon, extant Felidae species exhibit the greatest diversity in fur patterns of all terrestrial carnivores. Cats have retractile claws, slender muscular bodies and strong flexible forelimbs. Their teeth and facial muscles allow for a powerful bite. They are all obligate carnivores, and most are solitary predators ambushing or stalking their prey. Wild cats occur in Africa, Europe, Asia and the Americas. Some wild cat species are adapted to forest and savanna habitats, some to arid environments, and a few also to wetlands and mountainous terrain. Their activity patterns range from nocturnal and crepuscular to Diurnality, diurnal, depending on their preferred prey species. Reginald Innes Pocock divided the extant Felidae into three subfamilies: the Pantherinae, the Felinae and the Acin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joshua Brookes
Joshua Brookes (24 November 1761 – 10 January 1833) was a British anatomist and naturalist. Early life Brookes studied under William Hunter, William Hewson, Andrew Marshall, and John Sheldon, in London. He then attended the practice of Antoine Portal and other eminent surgeons at the Hôtel-Dieu de Paris. Brookesian Museum Brookes became a teacher of anatomy in London, and the founder of the Brookesian Museum of Comparative Anatomy. This private museum is described in the 1830 catalogue ''Museum Brookesianum''. Later life Elected a Fellow of the Royal Society in 1819, Brookes gave up teaching in 1826, in bad health. After vainly endeavouring to dispose of his museum collection entire, he sold it off piecemeal. The final sale took place on 1 March 1830, and on 22 following days. He died on 10 January 1833 in Great Portland Street, London. Works Brookes was the first to place the Cheetah in its own genus, which he established in 1828 as ''Acinonyx''. His published writi ...
