Miracinonyx (colloquially known as the "American 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 ...
An illustration of the "woolly cheetah" (described as Felis lanea) from the Proceedings of the Zoological Society of London (1877) In 1777, Johann Christian Daniel von Schreber described the cheetah based on a skin from the Cape of Good Hope and gave it the scientific name Felis jubatus. [11] Joshua Brookes proposed the generic name Acinonyx in ...
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...

Acinonyx intermedius by Thenius in 1954 [10] Acinonyx aicha by Geraads in 1997 [11] Acinonyx pleistocaenicus by Zdansky in 1925 [12] 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.

Edward Hitchcock's fold-out paleontological chart in his 1840 Elementary Geology. Although tree-like diagrams have long been used to organise knowledge, and although branching diagrams known as claves ("keys") were omnipresent in eighteenth-century natural history, it appears that the earliest tree diagram of natural order was the 1801 "Arbre botanique" (Botanical Tree) of the French ...
An illustration of a cheetah cub (Acinonyx jubatus guttata) by Joseph Wolf in the Proceedings of the Zoological Society of London, 1867The Southern African cheetah was first described by German naturalist Johann Christian Daniel von Schreber in his book Die Säugethiere in Abbildungen nach der Natur mit Beschreibungen (The Mammals illustrated as in Nature with Descriptions), published in 1775.
The earliest African cheetah fossils from the early Pleistocene have been found in the lower beds of the Olduvai Gorge site in northern Tanzania. [7]Not much was known about the East African cheetah's evolutionary story, although at first, the East and Southern African cheetahs were thought to be identical as the genetic distance between the two subspecies is low.
