A peccary is a pig-like ungulate of the family Tayassuidae. They are found throughout Central and South America, Trinidad in the Caribbean, and in the southwestern area of North America. They usually measure between 90 and 130 cm in length, and a full-grown adult usually weighs about 20 to 40 kg. They represent the closest relatives of the family Suidae, which contains pigs and relatives. Together Tayassuidae and Suidae are grouped in the suborder Suina within the order Artiodactyla.
Camelops is an extinct genus of camels that lived in North and Central America, ranging from Alaska to Honduras, from the middle Pliocene to the end of the Pleistocene. It is more closely related to the Old World dromedary and bactrian and wild bactrian camels than to the New World guanaco, vicuña, alpaca and llama; making it a true camel of the Camelini tribe. Its name is derived from the Ancient Greek κάμηλος and ὄψ, i.e. "camel-face".
The collared peccary is a species of artiodactyl (even-toed) mammal in the family Tayassuidae found in North, Central, and South America. It is the only member of the genus Dicotyles. They are commonly referred to as javelina, saíno, taitetu, or báquiro, although these terms are also used to describe other species in the family. The species is also known as the musk hog. In Trinidad, it is colloquially known as quenk.
Sistema Ox Bel Ha is a cave system in Quintana Roo, Mexico. It is the longest explored underwater cave in the world and ranks second including dry caves. As of January 2023 the surveyed length is 435.8 kilometers (270.8 mi) of underwater passages. There are more than 150 cenotes in the system.
The John Day Formation is a series of rock strata exposed in the Picture Gorge district of the John Day River basin and elsewhere in north-central Oregon in the United States. The Picture Gorge exposure lies east of the Blue Mountain uplift, which cuts southwest–northeast through the Horse Heaven mining district northeast of Madras. Aside from the Picture Gorge district, which defines the type, the formation is visible on the surface in two other areas: another exposure is in the Warm Springs district west of the uplift, between it and the Cascade Range, and the third is along the south side of the Ochoco Mountains. All three exposures, consisting mainly of tuffaceous sediments and pyroclastic rock rich in silica, lie unconformably between the older rocks of the Clarno Formation below and Columbia River basalts above.
Mount Blanco is a small white hill — an erosional remnant — located on the eastern border of the Llano Estacado within Blanco Canyon in Crosby County, Texas. With Blanco Canyon, it is the type locality of the early Pleistocene Blanco Formation of Texas and Kansas, as well as the Blancan fauna, which occurs throughout North America. Mount Blanco is a Late Blancan age site, and is associated with other Late Blancan sites from Texas such as Red Light and Hudspeth local faunas from Hudspeth County, and the Cita Canyon fauna from Randall County.
Arctodus is an extinct genus of short-faced bear that inhabited North America during the Pleistocene. There are two recognized species: the lesser short-faced bear and the giant short-faced bear. Of these species, A. simus was larger, is known from more complete remains, and is considered one of the most charismatic of North America's 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 Late Pleistocene of the United States, Mexico and Canada. A. simus evolved from A. pristinus, but both species likely overlapped in the Middle Pleistocene. Both species are relatively rare in the fossil record.
The Haile Quarry or Haile sites are an Early Miocene and Pleistocene assemblage of vertebrate fossils located in the Haile quarries, Alachua County, northern Florida. The assemblage was discovered during phosphate mining, which began in the late 1940s. Haile sites are found in the Alachua Formation. Two sites within the Ocala Limestone yielded Upper Eocene Valvatida and mollusks.
Platygonus compressus, the flat-headed peccary, is an extinct mammal species from the Tayassuidae family that lived in North and South America during the Pleistocene. It was first described in 1848 by John L. Leconte.
A list of prehistoric and extinct species whose fossils have been found in the La Brea Tar Pits, located in present-day Hancock Park, a city park on the Miracle Mile section of the Mid-Wilshire district in Los Angeles, California.
The Ash Hollow Formation of the Ogallala Group is a geological formation found in Nebraska and South Dakota. It preserves fossils dating back to the Neogene period. It was named after Ash Hollow, Nebraska and can be seen in Ash Hollow State Historical Park. Ashfall Fossil Beds State Historical Park is within this formation.
Floridachoerus olseni is an extinct peccary that lived during the Hemingfordian age of the Early Miocene, and was endemic to North America. F. olseni was in existence for approximately 4.46 million years. Remains of this extinct mammal were located at the fossil rich Thomas Farm site in Gilchrist County, Florida and Toledo Bend site, Newton County, Texas. Floridachoerus olseni was named after Stanley. J. Olsen of the Florida Geological Survey in 1962. Olsen previously worked at the site for Harvard University.
Surameryx is an extinct genus of herbivorous artiodactyls originally described as belonging to the extinct family Palaeomerycidae. A single species, S. acrensis, was described from the Late Miocene of the Madre de Dios Formation, South America. It was originally interpreted as one of the few northern mammals that entered South America before the Pliocene. However, both its identification as a member of the family Palaeomerycidae and claims about its Miocene age were subsequently challenged.
The Pleistocene coyote, also known as the Ice Age coyote, is an extinct subspecies of coyote that lived in western North America during the Late Pleistocene era. Most remains of the subspecies were found in southern California, though at least one was discovered in Idaho. It was part of a North American carnivore guild that included other canids like foxes, gray wolves, and dire wolves. Some studies suggest that the Pleistocene "coyote" was not in fact a coyote, but rather an extinct western population of the red wolf.
The long-nosed peccary is an extinct mammal species of the peccary family (Tayassuidae). It is one of two peccary-species that existed in the US-Midwest during the last ice age.

Catagonus stenocephalus is an extinct species of peccary that lived in South America during the Late Pleistocene. Fossils have been found in Brazil, Argentina and Bolivia. It is commonly known as the narrow-headed peccary due to its long and markedly convex rostrum.
Prosthennops is a genus of extinct peccaries that lived in North and Central America between the middle Miocene and lower Pliocene.
