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.
Extinct animals of the United States (1 C, 136 P) Pages in category "Extinct animals of North America" The following 44 pages are in this category, out of 44 total.
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
Extinctions in North America were concentrated at the end of the Late Pleistocene, around 13,800–11,400 years Before Present, which were coincident with the onset of the Younger Dryas cooling period, as well as the emergence of the hunter-gatherer Clovis culture. The relative importance of human and climactic factors in the North American ...
While Australia is a continent and not an island, due to its geographical isolation, its unique fauna has suffered an extreme decline in mammal species, 10% of its 273 terrestrial mammals, since European settlement (a loss of one to two species per decade); in contrast, only one species in North America has become extinct since European settlement.
The last two genera, Cuvieronius ranging southern North America to western South America, and Notiomastodon ranging over most of South America, continued to exist until the end of the Pleistocene around 12,000 years ago, when they became extinct along with many other megafauna species following the arrival of humans.
Castoroides (from Latin castor (beaver) and -oides (like) [2]), or the giant beaver, is an extinct genus of enormous, bear-sized beavers that lived in North America during the Pleistocene. Two species are currently recognized, C. dilophidus in the Southeastern United States and C. ohioensis in most of North America.
The species became extinct approximately 11,500 years ago, toward the end of the most recent ice age, as part of a mass extinction of large North American mammals. [ 7 ] [ 8 ] The first evidence of Cervalces scotti found in modern times was discovered at Big Bone Lick , Kentucky by William Clark , circa 1805.
