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 ...
Map of North America. This is a list of North American animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. [1] Recently extinct animals in the West Indies and Hawaii are in their own respective lists.
The American lion (Panthera atrox (/ ˈ p æ n θ ər ə ˈ æ t r ɒ k s /), with the species name meaning "savage" or "cruel", also called the North American lion) is an extinct pantherine cat native to North America during the Late Pleistocene from around 130,000 to 12,800 years ago.
Two main species of big cat once inhabited the United States. One is the jaguar (Panthera onca), which is related to many species of big cat found on other continents.Though there are single jaguars now living within Arizona, [2] the species has largely been extirpated from the United States (in the states of Texas, Colorado, New Mexico, and Louisiana) since the early 20th century; although it ...
The relative importance of human and climactic factors in the North American extinctions has been the subject of significant controversy. Extinctions totalled around 35 genera. [4] The radiocarbon record for North America south of the Alaska-Yukon region has been described as "inadequate" to construct a reliable chronology. [47]
Homotherium is an extinct genus of scimitar-toothed cat belonging to the extinct subfamily Machairodontinae that inhabited North America, Eurasia, and Africa (as well as possibly South America) during the Pliocene and Pleistocene epochs from around 4 million to 12,000 years ago.
The cat gap is a period in the fossil record of approximately 25 million to 18.5 million years ago in which there are few fossils of cats or cat-like species found in North America. The cause of the "cat gap" is disputed, but it may have been caused by changes in the climate (global cooling), changes in the habitat and environmental ecosystem ...
Hoplophoneus (Greek: "murder" (phonos), "weapon" (hoplo) [1]) is an extinct genus of the family Nimravidae, endemic to North America during the Late Eocene to Early Oligocene epochs (35–29 mya), existing for approximately 2]
