* The now-extinct American cheetah ( Miracinonyx )

The extinct genus Miracinonyx was extremely cheetah-like, but recent DNA analysis has shown that Miracinonyx inexpectatus, Miracinonyx studeri, and Miracinonyx trumani ( early to late Pleistocene epoch ), found in North America and called the " North American cheetah " are not true cheetahs, instead being close relatives to the cougar.

* American cheetah ( Miracinonyx inexpectatus )

The bestiary for this savannah landscape reads like a " who's-who " for some of the most unique creatures to inhabit North America – animals such as: Geochelone, a giant bathtub-sized tortoise ; Aiolornis incredibilis, the largest flying bird of the northern hemisphere, with wing span ; Paramylodon, Megalonyx and Nothrotheriops, giant ground sloths, some with bony armor within their skin ; Pewelagus, a very small rabbit ( paleontologists can name with a sense of humor ); Borophagus, a hyena-like dog ; Acrtodus, a giant short-faced bear ; Smilodon, a saber-toothed cat ; Miracinonyx, the North American cheetah ; Mammuthus imperator, the largest known mammoth ; Tapirus, an extinct tapir ; Equus enormis and Equus scotti, two species of extinct Pleistocene horse ; Gigantocamelus a giant camel ; and Capromeryx, the dwarf pronghorn.

Pleistocene fauna in the Americas included giant sloths ; short faced bears ; several species of tapirs ; peccaries ( Including the long nosed and flat-headed peccaries ); the American lion ; giant condors ; Miracinonyx (" American cheetahs ", not true cheetahs ); saber-toothed cats like Xenosmilus, Smilodon and the scimitar cat, Homotherium ; dire wolves ; saiga ; camelids such as two species of now extinct llamas and Camelops ; at least two species of bison ; stag-moose ; the shrub-ox and Harlan's muskox ; horses ; mammoths and mastodons ; and giant beavers as well as birds like teratorns and Titanis and giant tortoises.

German mammalogist Helmut Hemmer even suggested that it was an extant specimen of the prehistoric American cheetah ( Miracinonyx trumani ).

In fact, predation by Miracinonyx is thought to be the reason that pronghorns evolved to run so swiftly, their 60 mph top speed being much more than needed to outrun extant American predators such as cougars and gray wolves.

Inconsistent with McKenna and Bell, three additional prehistoric genera, Miracinonyx, Lokontailurus and Xenosmilus, are listed.
