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