Tapiroidea
Tapiroidea is a superfamily of Perissodactyla, perissodactyls which includes the modern tapir, tapirs and their extinct relatives. Taxonomically, they are placed in suborder Ceratomorpha along with the rhino superfamily, Rhinocerotoidea. The first members of Tapiroidea appeared during the Early Eocene, 55 million years ago, and were present in North America and Asia during the Eocene. Tapiridae first appeared during the early Oligocene in Europe, and are thought to have originated from the tapiroid family Helaletidae.

Perissodactyla
Perissodactyla (, ), or odd-toed ungulates, is an order of ungulates. The order includes about 17 living species divided into three families: Equidae (horses, asses, and zebras), Rhinocerotidae (rhinoceroses), and Tapiridae (tapirs). They typically have reduced the weight-bearing toes to three or one of the five original toes, though tapirs retain four toes on their front feet. The nonweight-bearing toes are either present, absent, vestigial, or positioned posteriorly. By contrast, artiodactyls (even-toed ungulates) bear most of their weight equally on four or two (an even number) of the five toes: their third and fourth toes. Another difference between the two is that perissodactyls digest plant cellulose in their intestines, rather than in one or more stomach chambers as artiodactyls, with the exception of Suina, do. The order was considerably more diverse in the past, with notable extinct groups including the brontotheres, palaeotheres, chalicotheres, and the paracer ...

Tapiridae
Tapirs ( ) are large, herbivorous mammals belonging to the family Tapiridae. They are similar in shape to a pig, with a short, prehensile nose trunk (proboscis). Tapirs inhabit jungle and forest regions of South and Central America and Southeast Asia. They are one of three extant branches of Perissodactyla (odd-toed ungulates), alongside equines and rhinoceroses. Only a single genus, ''Tapirus'', is currently extant. Tapirs migrated into South America during the Pleistocene epoch from North America after the formation of the Isthmus of Panama as part of the Great American Interchange. Tapirs were formerly present across North America, but became extinct in the region at the end of the Late Pleistocene, around 12,000 years ago. Name The term ''tapir'' comes from the Portuguese-language words , , which themselves trace their origins back to Old Tupi, specifically the term . This word, according to Eduardo de Almeida Navarro, referred in a more precise manner to the species '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Paracolodon'' is an extinct genus of tapiroid perissodactyl belonging to the family Helaletidae.

Its border includes two-thirds of the length of China's China–Mongolia border, border with the country of Mongolia. ... region of China. Taxonomy Matthew and Granger (1925) described the nominal tapiroid taxa ''Colodon inceptus'' and ''Paracolodon curtus'' from Eocene-age deposits in East Asia. Radinsky (1965) recognized two nominal species as identical and synonymized ''Paracolodon'' with ''Colodon inceptus''. Dashzeveg and Hooker (1997) assigned the nominal tapiroid species ''"Helalestes" fissus'' to ''Colodon'', as ''C. fissus'', based on similarities with ''inceptus''. On the basis of new material from the Erlian Basin in Inner Mongolia, Bai et al. (2017) recognized ''Paracolodon'' as a d ...

Indolophus
Indolophus is an extinct genus of perissodactyl belonging to the clade Tapiromorpha, which includes modern-day tapirs. Fossils have been found in the Early Eocene of Myanmar. Description ''Indolophus'' can be distinguished from other tapiromorphs in the characteristics of the upper dentition Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiology ...; it is distinguished from other basal tapiromorphs in having a more developed molar and protolophid and hypolophid. ''Indolophus'' is more primitive than tapiroids due to the lophodont dentiton and the absence of lingual and buccal cingula and molar metaconule.Tsubamoto, T., Soe Thura Tun, Egi, N., Takai, M., Shigehara, N., Aung Naing Soe, Aye Ko Aung, and Tin Thein. 2003.
