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.
