Common name	Scientific name	Range	Comments	Pictures
Stag-moose	Cervalces scotti	Great Lakes Region	Most recent remains dated to 9230-8930 BCE.[3]
Eastern elk	Population of the North American wapiti (Cervus canadensis canadensis)	Eastern North America	Traditionally considered the nominate subspecies, but genetic research indicates that there are not enough differences to consider separate subspecies of C. canadensis in North America, and the taxon C. c. canadensis is not extinct as a result.[43][44] The last confirmed individual was killed near the Clarion River of central Pennsylvania in 1867, though there were unconfirmed sightings in 1869-1870, and ten claimed killings in northern Pennsylvania in 1878. Western elk were reintroduced for hunting purposes in the same state in 1912.[45]
Merriam's elk	Population of the North American wapiti (Cervus canadensis canadensis)	New Mexico, Arizona, and West Texas	Named as the species Cervus merriami in 1902 on the basis of a single skull; in 1978, an anatomical review of a dozen individuals found just enough of a case to consider it a subspecies of Cervus elaphus (later C. canadensis). Further anatomical and genetic research suggest that all American wapiti likely belong to the same subspecies and that the taxon C. c. merriami is a synonym of C. c. canadensis. Wapiti from other regions have been reintroduced to the purported distribution area of Merriam's elk.[44]
Queen Charlotte Islands caribou	Population of the caribou (Rangifer tarandus)	Graham Island, British Columbia	Described as the subspecies R. t. dawsoni in 1900 due to its isolated location and anatomical differences, but mtDNA studies in 2002 showed not enough differences to warrant separate status.[46] The last known herd was found in 1908, comprising two adult males, one female, and one calf; all but the calf were killed.[47]

Common name	Scientific name	Range	Comments	Pictures
Painted vulture	Sarcoramphus sacra	Florida	Hypothetical species known from a 1774 description by William Bartram. Though traditionally dismissed as a hoax or incorrect description of a king vulture from Central and South America (S. papa), which it resembled in everything except the tail's coloration and more predatory behavior, a 1734 account of the same bird and painting by Eleazar Albin, and a 1786 depiction of the tail feathers as part of a standard used by the Muscogee king Mico Chlucco suggest that it was an actual extirpated Floridan population of the king vulture, subspecies, or related species.[64]

Extinct in the wild edit

Common name	Scientific name	Range	Comments	Pictures
Wyoming toad	Anaxyrus baxteri	Laramie Basin, Wyoming	Survives only at the four-times impounded Mortenson Lake National Wildlife Refuge, where it last reproduced naturally in 1991 and is re-stocked annually with captive born toadlets. The species is affected by chytridiomycosis, bacteria, pesticides, irrigation practices, lack of genetic diversity, predation by mustelids, drought, increased salinity, and expansion of the salt cedar which reduces habitat suitability.[77]
Panamanian golden frog	Atelopus zeteki	El Valle de Antón and Cerro Campana, Panama	Last recorded in the wild in 2009. The species is mainly threatened by chytridiomycosis, but also deforestation, water pollution, collection for the pet trade, and increased sedimentation of streams caused by road construction.[78]

Suckers (family Catostomidae) edit

Common name	Scientific name	Range	Comments	Pictures
Snake River sucker	Chasmistes muriei	Jackson Lake, Wyoming and possibly the Snake River	Only known from the holotype collected in 1927. Likely extinct due to hybridization with the Utah sucker after the Jackson Lake Dam was built and blocked spawning migration.[86]
Harelip sucker	Lagochila lacera	Southeastern United States	Last collected in 1893. Though originally abundant and widely spread, the species inhabited only deep clearwater pools and fed almost entirely on molluscs. It likely became extinct due to increased siltation and turbidity caused by agriculture practices, which both reduced the number of molluscs and made them more difficult to find.[86]
