Tayassuidae
Peccaries (also javelinas or skunk pigs) are pig-like ungulates of the family Tayassuidae (New World pigs). They are found throughout Central and South America, Trinidad in the Caribbean, and in the southwestern area of North America. Peccaries usually measure between in length, and a full-grown adult usually weighs about . 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 ( even-toed ungulates). Peccaries are social creatures that live in herds. They are omnivores and eat roots, grubs, and a variety of other foods. They can identify each other by their strong odors. A group of peccaries that travel and live together is called a squadron. A squadron of peccaries averages between six and nine members. Peccaries first appeared in North America during the Miocene and migrated into South America during the Pliocene–Pleistocene as part of t ...

Suina
Suina (also known as Suiformes) is a suborder of omnivorous, non- ruminant artiodactyl mammals that includes the domestic pig and peccaries. A member of this clade is known as a suine. Suina includes the family Suidae, termed suids, known in English as pigs or swine, as well as the family Tayassuidae, termed tayassuids or peccaries. Suines are largely native to Africa, South America, and Southeast Asia, with the exception of the wild boar, which is additionally native to Europe and Asia and introduced to North America and Australasia, including widespread use in farming of the domestic pig subspecies. Suines range in size from the 55 cm (22 in) long pygmy hog to the 210 cm (83 in) long giant forest hog, and are primarily found in forest, shrubland, and grassland biomes, though some can be found in deserts, wetlands, or coastal regions. Most species do not have population estimates, though approximately two billion domestic pigs are used in farming, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collared Peccary
The collared peccary (''Dicotyles tajacu'') is a peccary, a species of artiodactyl (even-toed) mammal in the family Peccary, Tayassuidae found in North America, North, Central America, 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''. Taxonomy Although somewhat related to true Old World pigs, and frequently referred to as a pig, this species and the other peccaries are no longer classified in the pig family, Suidae. Although formerly classified in the genus ''Pecari'', studies in 2020 placed them in the genus ''Dicotyles'', based on an unequivocal type-species selection; these studies have been accepted by the American Society of Mammalogists. Currently, the IUCN still places them in the genus ''Pecar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Platygonus
''Platygonus'' ("flat head" in reference to the straight shape of the forehead) is an extinct genus of herbivorous peccaries of the family Tayassuidae, endemic to North and South America from the Miocene through Pleistocene epochs (10.3 million to 11,000 years ago), existing for about . ''P. compressus'' stood tall. Taxonomy While long thought to be the sister-lineage to the Chacoan peccary based on morphological similarities, a 2017 ancient DNA study which recovered mitochondrial DNA from ''Platygonus'' found that all living peccaries are more closely related to each other than they are to ''Platygonus''. The estimated divergence between ''Platygonus'' and all living peccaries was placed in the Miocene, around 22 million years ago. Description Most ''Platygonus'' species were similar in size to modern peccaries especially giant peccary, at around in body length, and had long legs, allowing them to run well. They also had a pig-like snout and long tusks which were prob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tayassu
The white-lipped peccary (''Tayassu pecari'') is a species of peccary found in Central and South America and the only member of the genus ''Tayassu''. Multiple subspecies have been identified. White-lipped peccaries are similar in appearance to pigs, but covered in dark hair (except on certain regions, such as the throat, where it is cream). The range of ''T. pecari'', which extends from Mexico to Argentina, has become fragmented, and the species's population is declining overall (especially in Mexico and Central America). They can be found in a variety of habitats. Social animals, white-lipped peccaries typically forage in large groups, which can have as many as 300 peccaries. They are an important part of their ecosystem and multiple efforts are being made to preserve them in the wild. Not all disappearances are explained, but human activities play a role, with two major threats being deforestation and hunting; the latter is very common in rural areas, although it can be dang ...

Artiodactyla
Artiodactyls are placental mammals belonging to the order (biology), order Artiodactyla ( , ). Typically, they are ungulates which bear weight equally on two (an even number) of their five toes (the third and fourth, often in the form of a hoof). The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, most perissodactyls bear weight on an odd number of the five toes. Another difference between the two orders is that many artiodactyls (except for Suina) digest plant cellulose in one or more stomach chambers rather than in their intestine (as perissodactyls do). Molecular biology, along with new fossil discoveries, has found that cetaceans (whales, dolphins, and porpoises) fall within this taxonomic branch, being most closely related to Hippopotamidae, hippopotamuses. Some modern taxonomists thus apply the name Cetartiodactyla () to this group, while others opt to include cetaceans within the existing name of Artiodactyla. Some researchers ...

Ungulate
Ungulates ( ) are members of the diverse clade Euungulata ("true ungulates"), which primarily consists of large mammals with Hoof, hooves. Once part of the clade "Ungulata" along with the clade Paenungulata, "Ungulata" has since been determined to be a polyphyletic and thereby invalid clade based on molecular data. As a result, true ungulates had since been reclassified to the newer clade Euungulata in 2001 within the clade Laurasiatheria while Paenungulata has been reclassified to a distant clade Afrotheria. Living ungulates are divided into two orders: Perissodactyla including Equidae, equines, rhinoceroses, and tapirs; and Artiodactyla including Bos, cattle, antelope, Sus (genus), pigs, giraffes, camels, Ovis, sheep, deer, and Hippopotamidae, hippopotamuses, among others. Cetaceans such as Whale, whales, Dolphin, dolphins, and Porpoise, porpoises are also classified as artiodactyls, although they do not have hooves. Most terrestrial ungulates use the hoofed tips of their toes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Catagonus
''Catagonus'' is a genus of peccaries that contains the living Chacoan peccary, C. wagneri, and several extinct species. The genus has always been restricted to South America. Taxonomy ''Catagonus'' is notable in that the type species, '' C. metropolitanus'', is extinct; the living Chacoan peccary was first described in 1930 from subfossil remains, and only found alive by scientists in 1972 (an example of a Lazarus taxon In paleontology, a Lazarus taxon (plural ''taxa'') is a taxon that disappears for one or more periods from the fossil record, only to appear again either in later fossil records, or as actual living organisms, and often in isolated, obscure, ...). A 2017 study on the phylogenetic systematics of Tayassuidae species suggests that ''Catagonus'' should only contain ''C. metropolitanus''. The extinct narrow-headed peccary ''(C. stenocephalus)'' should be moved into ''Brasiliochoerus'', while the Chacoan peccary, ''C. bonaerensis'' and ''C. carlesi'' should be ...

Great American Interchange
The Great American Biotic Interchange (commonly abbreviated as GABI), also known as the Great American Interchange and the Great American Faunal Interchange, was an important late Cenozoic paleozoogeographic biotic interchange event in which land and freshwater fauna (animals), fauna migrated from North America to South America via Central America and vice versa, as the volcanic Isthmus of Panama rose up from the sea floor, forming a land bridge between the previously separated continents. Although earlier dispersals had occurred, probably over water, the migration accelerated dramatically about 2.7 million years (Ma (unit), Ma) ago during the Piacenzian age. It resulted from the joining of the Neotropical realm, Neotropic (roughly South American) and Nearctic realm, Nearctic (roughly North American) biogeographic realms definitively to form the Americas. The interchange is visible from observation of both biostratigraphy and nature (neontology). Its most dramatic effect is on the ...

Portuguese Language
Portuguese ( or ) is a Western Romance language of the Indo-European language family originating from the Iberian Peninsula of Europe. It is the official language of Angola, Brazil, Cape Verde, Guinea-Bissau, Mozambique, Portugal and São Tomé and Príncipe, and has co-official language status in East Timor, Equatorial Guinea and Macau. Portuguese-speaking people or nations are known as Lusophone (). As the result of expansion during colonial times, a cultural presence of Portuguese speakers is also found around the world. Portuguese is part of the Iberian Romance languages, Ibero-Romance group that evolved from several dialects of Vulgar Latin in the medieval Kingdom of Galicia and the County of Portugal, and has kept some Gallaecian language, Celtic phonology. With approximately 250 million native speakers and 17 million second language speakers, Portuguese has approximately 267 million total speakers. It is usually listed as the List of languages by number of native speaker ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...
