The American cheetah is either of two feline species of the extinct genus Miracinonyx, endemic to North America during the Pleistocene epoch (2.6 million to 12,000 years ago) and morphologically similar to the modern cheetah (Acinonyx jubatus). These cats were originally known from fragments of skeletons, but nearly complete skeletons have been recovered from Natural Trap Cave in northern Wyoming.


American Cheetah is an extinct genus of two feline species that were endemic to North America. Their existence only came to be known from their skeleton samples. Species belonging to genus Miracinonyx were larger compared to modern Cheetah found in Africa. In fact, their size was similar to a cougar. Species The two species identified …


The American cheetah is an extinct genus of two feline species that were endemic to North America during the Pleistocene period: Miracinonyx inexpectatus and Miracinonyx intrumani. Researchers have pieced together fragments of an American cheetah skeleton to derive a picture of what these predators may have looked like.


The American cheetah has been extinct for about 12,000 years. The closest relative would be the cougar. Both animals are thought to have evolved from a common ancestor.

Extinct giants, such as the American cheetah and ground sloth, lived in North America until they mysteriously died out about 10,000 years ago.


American cheetahs most likely fed primarily on American pronghorn, which are the second fastest land mammals on the planet. Other prey may have included extinct mountain sheep and horses. Although there are still controversies regarding the evolution of the American cheetah, it is certain this was an impressive and influential animal in the ...


As with the American cheetah, the big-cat affiliations of the American lion (Panthera leo atrox) are in some doubt: This Pleistocene predator may actually have been more closely related to tigers and jaguars than to modern lions. The amazing thing about the American lion is that it coexisted and competed with both Smilodon (aka the saber-toothed tiger, below) and Canis dirus, also known as the ...


American Cheetah (Miracinonyx ) is an extinct genus of cheetahs. They lived in North America approximately 2.6 to 12,000 years ago. Although these cheetahs are only known from parts of skeletons that have been found, they were morphologically similar to modern cheetahs. American cheetahs were larger than modern cheetahs, weighing approximately 150 pounds and being 67 inches long with a tail ...
