Paracolodon
''Paracolodon'' is an extinct genus of tapiroid perissodactyl belonging to the family Helaletidae. Fossils have been found in Mongolia and the Inner Mongolia Inner Mongolia, officially the Inner Mongolia Autonomous Region, is an autonomous region of the People's Republic of China. Its border includes most of the length of China's border with the country of Mongolia. Inner Mongolia also accounts for ... 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 di ...

Tapiroidea
Tapiroidea is a superfamily of perissodactyls which includes the modern tapir. Members of the superfamily are small to large browsing mammals, roughly pig-like in shape, with short, prehensile snouts. Their closest relatives are the other odd-toed ungulates, including horses and rhinoceroses. 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. Evolution and natural history The first tapirids, such as '' Heptodon'', appeared in the early Eocene. They appeared very similar to modern forms, but were about half the size, and lack the proboscis. The first true tapirs, appeared in the Oligocene, and by the Miocene, such genera as ''Miotapirus'' were almost indistinguishable to the extant species. It is believed that Asian and American tapirs diverged around 20 to 30 million years ago, and that tapirs migrated from North America and Central Ame ...

Helaletidae
The Helaletidae is an extinct family of tapiroid Tapiroidea is a superfamily of perissodactyls which includes the modern tapir. Members of the superfamily are small to large browsing mammals, roughly pig-like in shape, with short, prehensile snouts. Their closest relatives are the other odd-toe ... closely related and likely ancestral to the true tapirs, which contain '' Protapirus'' and all descendants. In alternative classifications, the Helaletidae is treated as a subfamily within Tapiridae, the Helaletinae. Members of the family are defined by having less bilophodont cheek teeth compared to other tapiroids. References Prehistoric mammal families Odd-toed ungulates {{paleo-oddtoedungulate-stub ...

Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', " dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perissodactyl
Odd-toed ungulates, mammals which constitute the taxonomic order Perissodactyla (, ), are animals—ungulates—who have reduced the weight-bearing toes to three (rhinoceroses and tapirs, with tapirs still using four toes on the front legs) or one (equines, third toe) of the five original toes. The non-weight-bearing toes are either present, absent, vestigial, or positioned posteriorly. By contrast, the 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 odd-toed ungulates digest plant cellulose in their intestines rather than in one or more stomach chambers as even-toed ungulates, with the exception of Suina, do. The order includes about 17 species divided into three families: Equidae (horses, asses, and zebras), Rhinocerotidae (rhinoceroses), and Tapiridae (tapirs). Despite their very different appearances, they were recognized as related families ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongolia
Mongolia; Mongolian script: , , ; lit. "Mongol Nation" or "State of Mongolia" () is a landlocked country in East Asia, bordered by Russia to the north and China to the south. It covers an area of , with a population of just 3.3 million, making it the world's most sparsely populated sovereign nation. Mongolia is the world's largest landlocked country that does not border a closed sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population. The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest contiguous land empire in history. His grandson Kublai Khan conquered China proper and established the Yuan dynasty.

Inner Mongolia
Inner Mongolia, officially the Inner Mongolia Autonomous Region, is an autonomous region of the People's Republic of China. Its border includes most of the length of China's border with the country of Mongolia. Inner Mongolia also accounts for a small section of China's border with Russia (Zabaykalsky Krai). Its capital is Hohhot; other major cities include Baotou, Chifeng, Tongliao, and Ordos. The autonomous region was established in 1947, incorporating the areas of the former Republic of China provinces of Suiyuan, Chahar, Rehe, Liaobei, and Xing'an, along with the northern parts of Gansu and Ningxia. Its area makes it the third largest Chinese administrative subdivision, constituting approximately and 12% of China's total land area. Due to its long span from east to west, Inner Mongolia is geographically divided into eastern and western divisions. The eastern division is often included in Northeastern China (Dongbei) with major cities including Tongliao, Chifeng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Tapirs
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
