Acinonyx is a genus within the Felidae family. [1] The only living species of the genus, the cheetah (A. jubatus), lives in open grasslands of Africa and Asia. [2]

Contents

Several fossil remains of cheetah-like cats were excavated that date to the late Pliocene and Middle Pleistocene. [3] 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 . [2]

Taxonomy

Acinonyx was proposed by Joshua Brookes in 1828. [4]

Between the late 18th century and the early 20th century, the following Acinonyx species and subspecies were described: [1]

In 1993, Acinonyx was placed in the monophyletic subfamily Acinonychinae. Molecular phylogenetic analysis has shown that it is the sister group of the genus Puma, and it is now placed within the subfamily Felinae. [1]

In addition, the following fossil Acinonyx species were described:

The "Linxia Cheetah" ("A. kurteni") was initially described by Christiansen and Mazák in 2009 on the basis of a skull from Pliocene strata in China, and touted as the most primitive member of the genus. [13] In 2012, "A. kurteni" was invalidated as a species when the holotype was determined to be a forgery composed of Miocene-aged fragments. [14] [15]

The cheetah is a large cat and the 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 67–94 cm (26–37 in) at the shoulder, and the head-and-body length is between 1.1 and 1.5 m. Adults weigh between 21 and 72 kg. The cheetah is capable of running at 93 to 104 km/h ; it has evolved specialized adaptations for speed, including a light build, long thin legs and a long tail.

Panthera is a genus within the family Felidae, and one of two extant genera in the subfamily Pantherinae. It contains the largest living members of the cat family. There are five living species: the jaguar, leopard, lion, snow leopard and tiger, as well as a number of extinct species, including the cave lion and American lion.

<i>Felis</i> Genus of mammals (cats)

Felis is a genus of small and medium-sized cat species native to most of Africa and south of 60° latitude in Europe and Asia to Indochina. The genus includes the domestic cat. The smallest of the seven Felis species is the black-footed cat with a head and body length from 38 to 42 cm. The largest is the jungle cat with a head and body length from 62 to 76 cm.

<i>Miracinonyx</i> Extinct genus of mammal

Miracinonyx is an extinct genus of felids belonging to the subfamily Felinae that was endemic to North America from the Pleistocene epoch and morphologically similar to the modern cheetah, although its apparent similar ecological niches have been considered questionable due to anatomical morphologies of the former that would have limited the 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.

<span class="mw-page-title-main">Felinae</span> Subfamily of Felidae

Felinae is a subfamily of the Felidae and comprises the small cats having a bony hyoid, because of which they are able to purr but not roar. Other authors have proposed an alternative definition for this subfamily, as comprising only the living conical-toothed cat genera with two tribes, the Felini and Pantherini, and excluding the extinct sabre-toothed Machairodontinae.

<span class="mw-page-title-main">Pantherinae</span> Subfamily of felids

The Pantherinae is a subfamily of the Felidae; it was named and first described by Reginald Innes Pocock in 1917 as only including the Panthera species, but later also came to include the clouded leopards. The Pantherinae genetically diverged from a common ancestor between 9.32 to 4.47 million years ago and 10.67 to 3.76 million years ago.

<i>Chasmaporthetes</i> Extinct genus of carnivores

Chasmaporthetes, also known as hunting or running hyena, is an extinct genus of hyenas distributed in Eurasia, North America, and Africa during the Pliocene-Pleistocene epochs, living from 4.9 million to 780,000 years ago, existing for about 4.12 million years. The genus probably arose from Eurasian Miocene hyenas such as Thalassictis or Lycyaena, with C. borissiaki being the oldest known representative. The species C. ossifragus was the only hyena to cross the Bering land bridge into the Americas, and ranged over what is now Arizona and Mexico during Blancan and early Irvingtonian Land Mammal ages, between 5.0 and 1.5 million years ago.

<i>Panthera palaeosinensis</i> Extinct species of carnivore

Panthera palaeosinensis was an early Pleistocene species from northern China. It is often incorrectly referenced as the ancestor of the tiger, Panthera tigris, although it shares features with all living large cats. Recent studies place it close to the base of the genus Panthera.

<span class="mw-page-title-main">Asiatic cheetah</span> Subspecies of cheetah in Asia

The Asiatic cheetah 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.

<span class="mw-page-title-main">Northwest African cheetah</span> Subspecies of carnivore

The Northwest African cheetah, also known as the Saharan cheetah, is a cheetah subspecies native to the Sahara and the Sahel. It is listed as Critically Endangered on the IUCN Red List. In 2008, the population was suspected to number less than 250 mature individuals.

<i>Acinonyx pardinensis</i> Extinct species of carnivore

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 during the Pliocene and Pleistocene epochs. It was substantially larger than the living cheetah.

<i>Acinonyx kurteni</i> Discredited fossil specimen

"Acinonyx kurteni", or the Linxia cheetah, is a discredited fossil specimen of an extinct cheetah discovered in China. The scientific name was assigned for the skull that was originally described to be that of an extinct species of cheetah, endemic to Asia during the Late Pliocene sub-epoch. It was estimated to have lived around 2.2 to 2.5 Ma BP, existing for approximately 0.3 million years.

<i>Rucervus</i> Genus of deer native to Asia

Rucervus is a genus of deer from India, Nepal, Indochina, and the Chinese island of Hainan. The only extant representatives, the barasingha or swamp deer and Eld's deer, are threatened by habitat loss and hunting; another species, Schomburgk’s deer, went extinct in 1938. Deer species found within the genus Rucervus are characterized by a specific antler structure, where the basal ramification is often supplemented with an additional small prong, and the middle tine is never present. The crown tines are inserted on the posterior side of the beam and may be bifurcated or fused into a small palmation.

Acinonyx intermedius is a fossil species of felid belonging to the cheetah genus Acinonyx. It was described by paleontologist Thenius in 1954. It is sometimes considered part of Acinonyx pardinensis as A. p. intermedius.

Deng Tao is a Chinese palaeontologist at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences, who has made important fossil discoveries on Cenozoic mammals. He is a professor of vertebrate palaeontology, deputy director of the Academic Committee, and deputy director of Key Laboratory of Evolutionary Systematics of Vertebrates at IVPP.

<span class="mw-page-title-main">East African cheetah</span> Subspecies of carnivore

The East African cheetah, is a cheetah population in East Africa. It lives in grasslands and savannas of Tanzania, Kenya, Uganda and Somalia. The cheetah inhabits mainly the Serengeti ecosystem, including Maasai Mara, and the Tsavo landscape.

<span class="mw-page-title-main">Northeast African cheetah</span> Subspecies of carnivore

The Northeast African cheetah is a cheetah subspecies occurring in Northeast Africa. Contemporary records are known in South Sudan, Uganda, and Ethiopia, but population status in Eritrea, Djibouti, Somalia, Kenya, and Sudan is unknown.

<span class="mw-page-title-main">Southeast African cheetah</span> Subspecies of carnivore

The Southeast African cheetah is the nominate cheetah subspecies native to East and Southern Africa. The Southern African cheetah lives mainly in the lowland areas and deserts of the Kalahari, the savannahs of Okavango Delta, and the grasslands of the Transvaal region in South Africa. In Namibia, cheetahs are mostly found in farmlands. In India, four cheetahs of the subspecies are living in Kuno National Park in Madhya Pradesh after having been introduced there.

Sivapanthera is a prehistoric genus of felid described by Kretzoi in 1929. Species of Sivapanthera are closely related to the modern cheetah but differ from modern cheetahs by having relatively longer brain cases, flatter foreheads, narrower nostrils and larger teeth. In many ways, skulls of Sivapanthera show similarity to that of the puma, or even those of Panthera. Scholars differ on the validity of this genus, while some think that it should be treated as a distinct genus, others think that its members should be treated as members of the Acinonyx genus, or even as subspecies of Acinonyx pardinensis.

Gallogoral is an extinct genus of caprine that lived in Europe during the Pliocene and Pleistocene epochs.
