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.
Equus simplicidens, also known as the Hagerman horse and American zebra, is an extinct species of equine native to North America during the Pliocene and Early Pleistocene. [1] It is one of the oldest and most primitive members of the genus Equus .
Equus scotti is a true caballine horse that is more closely related to modern horses than to zebras and asses. Equus scotti may be synonymous with Equus lambei , another generally smaller horse known from the Pleistocene of North America, but this is uncertain. [ 3 ]
Caballine true horses (Equus cf. ferus) from the Late Pleistocene of North America have historically been assigned to many different species, including Equus fraternus, Equus scotti and Equus lambei, but the taxonomy of these horses is unclear, and many of these species may be synonymous with each other, perhaps only representing a single species.
The giant horse (Equus giganteus) is an extinct species of horse which lived in North America. It was classified as a species based on the finding of a single tooth larger than the teeth of even the largest modern draft horses .
Like Equidae more broadly, Equus has numerous extinct species known only from fossils. The genus originated in North America and dispersed into the Old World and South America during the Early and Middle Pleistocene. Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes (erect in most subspecies), and long ...
Skeleton from the La Brea tar pits. Equus occidentalis (commonly known as the western horse) is an extinct species of wild horse that once inhabited North America, specifically the Southwestern United States, during the Pleistocene epoch.
Equus lambei, commonly known as the Yukon horse or Yukon wild horse, [1] [2] is an extinct species of the genus Equus. Equus lambei ranged across North America until approximately 10,000 years ago. Based on recent examinations of the mtDNA of Equus lambei remains, scientists have concluded that E. lambei was probably much like the extinct ...
