Possible last sighting in 1942, but it could also have been a brown morph of the American black bear.

Earless seals (family Phocidae)

Common name	Scientific name	Range	Comments	Pictures
Caribbean monk seal	Neomonachus tropicalis	Caribbean Sea, Bahamas, and the Gulf of Mexico	Last recorded in southern Florida in 1922 and Yucatan in 1950. It was intensely hunted for its skin and oil, and persecuted as a competitor by fishermen in later times.

Common name	Scientific name	Range	Comments	Pictures
Sea mink	Neogale macrodon	Atlantic coast of Canada and New England	Hunted to extinction by fur traders by about 1860. Later records up to 1894 are actually references to the American mink.

Horses and allies (family Equidae)

Common name	Scientific name	Range	Comments	Pictures
Mexican horse	Equus conversidens	Western North America	A small non-caballine species that coexisted in North America with the caballine horse (E. ferus). The most recent remains were dated to 8965-8875 BCE.

Locally extinct

Common name	Scientific name	Range	Comments	Pictures

The Yukon population has been identified at times as a different species of caballine horse (Equus lambei) and a wild ass (both Equus hemionus and Equus africanus) on morphological grounds, but ancient mtDNA studies confirms caballine affiliation. Domestic horses were introduced to the Americas by the Spanish in 1493 and a feral population was established in Querétaro, Mexico by 1553.

A single individual, presumably dispersed over the Arctic, was observed off Florida in 2023 and Nantucket, Massachusetts in 2024.

True deer (family Cervidae)

Locally extinct

Common name	Scientific name	Range	Comments	Pictures
Stag-moose	Cervalces scotti	Great Lakes Region	Most recent remains dated to 9230-8930 BCE.
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. 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.
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.
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. The last known herd was found in 1908, comprising two adult males, one female, and one calf; all but the calf were killed.

Common name	Scientific name	Range	Comments	Pictures
Passenger pigeon	Ectopistes migratorius	Eastern North America	One of the most numerous birds at the beginning of the 19th century, it declined dramatically as a result of hunting, Newcastle disease, and the clearance of hardwood trees in which it fed, until the last individual in the wild was shot in 1900.

Extinct in the wild

Common name	Scientific name	Range	Comments	Pictures
Socorro dove	Zenaida graysoni	Socorro Island, Mexico	Last recorded in the wild in 1972.

Declined due to hunting, conversion of prairies for agriculture, and the suppression of the fire regime. The breeding grounds in the Arctic have since been taken over by the larger Hudsonian whimbrel. Another factor may have been the extinction of the Rocky Mountain locust.

Northern storm petrels (family Hydrobatidae)

Possibly extinct

Common name	Scientific name	Range	Comments	Pictures
Guadalupe storm-petrel	Hydrobates macrodactylus	Guadalupe Island, Mexico	Last recorded in 1912. Likely extinct due to breeding habitat degradation by introduced feral goats and predation by feral cats and dogs; however the natural difficulty of its detection, lack of thorough surveys in the breeding season after 1906 and reports of unidentified storm-petrel calls at night may indicate that it is still extant.

New World vultures and condors (family Cathartidae)

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.

In 1981 the last five individuals, all male, were captured and taken into captivity. However, a proposed plan to hybridize them with Scott's seaside sparrow and select the offspring with most dusky ancestry wasn't allowed because of legal restrictions against hybridizing endangered taxa.

Suckers (family Catostomidae)

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.
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.

Pahranagat spinedace	Lepidomeda altivelis	Pahranagat Valley, Nevada	Last collected in 1938. Extinct due to predation by, and competition with the mosquitofish and other introduced species.
Durango shiner	Notropis aulidion	Tunal River, Durango, Mexico	Last collected in 1961. Possibly extinct due to pollution, competition and predation by the largemouth bass and other introduced species.

Phantom shiner	Notropis orca	Rio Grande	The only pure individual known is the holotype taken in 1975, though hybrids with the bluntnose shiner are known as far as 1891. Possibly extinct due to changes to the water flow (which increased hybridization), increased salinity caused by irrigation, and introduced fish species.

Declined after the introduction of several exotic species including mosquitofishes, sailfin mollies, guppies, convict cichlids, and green swordtails, followed by the alteration of water flows related to the use of hotsprings as public baths and sewage spillage. As numbers fell the subspecies became more vulnerable to hybridization with R. c. cataractae, which caused its final extinction.
Las Vegas dace	Rhinichthys deaconi	Las Vegas Valley, Nevada	Last collected in 1940. The springs it inhabited were destroyed during the urban development of Las Vegas.
Grass Valley speckled dace	Rhinichthys osculus reliquus	Lander County, Nevada	Known only from the type series of 474 specimens collected in 1938. Though abundant in this time, it was completely gone and replaced by introduced rainbow trout and brook trout when a second collection attempt was made in 1969.
Stumptooth minnow	Stypodon signifer	Southern Coahuila, Mexico	Last collected in 1903. It was a mollusc-eating specialist, and molluscs were greatly affected by habitat modification and pollution caused by agriculture.
