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 ...
Cheetahs can overtake a running antelope with a 140 m (150 yd) head start. Both animals were clocked at 80 km/h (50 mph) by speedometer reading while running alongside a vehicle at full speed. [106] Cheetahs can easily capture gazelles galloping at full speed (70–80 km/h (43–50 mph)). [63] The physiological reasons for speed in cheetahs are:
Though not an antelope, it is known colloquially in North America as the American antelope, prong buck, pronghorn antelope and prairie antelope, [5] because it closely resembles the antelopes of the Old World and fills a similar ecological niche due to parallel evolution. [6] It is the only surviving member of the family Antilocapridae. [7]
In the wet seasons, they eat mainly fresh grasses, [18] but during the dry seasons, they eat more browse, [18] particularly foliage from woody plants bushes and herbaceous forbs.

In the early 1900s, "antelope" was a very broad, ambiguous name given to most hollow-horned ruminants besides oxen, sheep, and goats. Of these antelopes found in Africa, Asia, and Europe, Africa has the most diverse populations of antelopes, with horn lengths ranging from six feet long, to a quarter of an inch. [14] A. b.
Acinonyx is a genus within the Felidae family. [1] The only living species of the genus, the cheetah (A. jubatus), lives in open grasslands of Africa and Asia. [2]Several fossil remains of cheetah-like cats were excavated that date to the late Pliocene and Middle Pleistocene. [3]

Antelope are a common symbol in heraldry, though they occur in a highly distorted form from nature. The heraldic antelope has the body of a stag and the tail of a lion, with serrated horns, and a small tusk at the end of its snout. This bizarre and inaccurate form was invented by European heralds in the Middle Ages, who knew little of foreign ...
