Arctodus is an extinct genus of short-faced bears that inhabited North America during the Pleistocene (about 2.6 Mya until 12,800 years ago). The two recognized species are the lesser short-faced bear (Arctodus pristinus) and the giant short-faced bear (Arctodus simus). Of these species, A. simus was larger, is known from more complete remains, and is considered one of the best-known members of North America's extinct Ice Age megafauna. A. pristinus was largely restricted to the Early Pleistocene of the eastern United States, whereas A. simus had a broader range, with most finds being from the

Teratornis (Greek: "wonder" (teras / gen.sg. teratos), "bird" (ornis)) is an extinct genus of huge North American birds of prey—the best-known of the teratorns—of which, two species are known to have existed: Teratornis merriami and Teratornis woodburnensis. A large number of fossil and subfossil bones, representing more than 100 individuals, have been found in locations in California, Oregon, southern Nevada, Arizona, and Florida, though most are from the Californian La Brea Tar Pits. All remains except one Early Pleistocene partial skeleton from the Leisey Shell Pit near Charlotte Harbor, Fl

Plotopteridae is an extinct family of flightless seabirds with uncertain placement, generally considered as member of order Suliformes. They exhibited remarkable convergent evolution with the penguins, particularly with the now extinct giant penguins. That they lived in the North Pacific, the other side of the world from the penguins, has led to them being described at times as the Northern Hemisphere's penguins, though they were not closely related. More recent studies have shown, however, that the shoulder-girdle, forelimb and sternum of plotopterids differ significantly from those of pengui

Chamitataxus is a prehistoric badger genus. Chamitataxus avitus is the only known species of the genus. Chamitataxus lived during the Late Miocene, around 6 million years ago in what is now North America. Out of the three taxidiine badger genera to have existed on the continent, Chamitataxus is the most primitive. Very few taxideine badger remains have been uncovered to date, with only prehistoric Taxidea and Pliotaxidea specimens being discovered prior to the Chamitataxus holotype being found.

Chendytes is a genus of extinct, goose-sized flightless marine duck, once common on the California coast, the California Channel Islands, and possibly southern Oregon. It lived in the Pleistocene and survived into the Holocene. It appears to have gone extinct at about 450–250 BCE. The youngest direct radiocarbon date from a Chendytes bone fragment dates to 770–400 BCE and was found in an archeological site in Ventura County. Its remains have been found in fossil deposits and in early coastal archeological sites. Archeological data from coastal California show a record of human exploi

Tapocyon ("dog from Tapo Canyon") is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America during the middle Eocene. Tapocyon was about the size of a coyote and is believed to have been a good climber that spent a lot of time in trees.

Dexteria floridana is an extinct species of fairy shrimp in the family Chirocephalidae, the only species in the genus Dexteria. It was endemic to Florida, where it was known from a single pool, south of Gainesville. It was originally described by Ralph W. Dexter in 1953 as a species of Eubranchipus. The species was declared extinct on October 5, 2011 because it was found that the only known pool of water that contained the known population was filled in for development, thereby killing the shrimps.
