That’s rhi-normous! 코끼리보다 4배나 무거운 거대 코뿔소, 중국 배회 26.5 million years ago and was the ‘largest land mammal that ever lived

  • The Paraceratherium linxiaense was a giant early ancestor of the modern rhino
  • It looked similar to a tapir with a large prehensile trunk that could grab branches
  • It was the ‘largest land mammalthat ever lived reaching 26ft long and 16ft tall
  • At peak height, with neck fully extended, it reached leaves on top of 23ft trees
  • A giant ancestor to the modern-day rhinoceros roamed 중국 26.5 백만년 전, according to the team that found its remains.

    It was the ‘largest land mammalthat ever lived, reaching 26ft long and 16ft tall, according to the team from the Chinese Academy of Sciences, 베이징.

    The colossal creature, named Paraceratherium linxiaense, weighed 24 tons and was four times heavier than an African elephant, the largest animal to walk the Earth today.

    The hornless herbivore roamed Asia 26.5 백만년 전 – browsing the forests for leaves, soft plants and shrubs and looked similar to an ‘overgrown tapir’.

    The fossilised remains of this giant beast, whose neck let it reach trees as high as 23ft, were dug up at a prehistoric animal graveyard in Gansu, north western China.

    The bizarre animal had a slender skull, short trunk and an unusually long and muscular neck, the Chinese researcher said, adding it was a ‘friendly giant’.

    PARACERATHERIUM: AN EXTINCT GENUS OF GIANT RHINO

    Paraceratherium is an extinct genus of hornless rhinoceros.

    It was one of the largest terrestrial mammals ever to have lived on land.

    The creature lived during the early to late Oligocene between 34 과 23 million year ago.

    It was found through Eurasia between China and the Balkans.

    The exact size isn’t known but the largest of the genus are thought to be as much as 26ft long and 23ft high including their neck.

    They survived for about 11 million years before going extinct, although the exact reason is unknown and it is unlikely there was a single cause.

    On the way across the Asian continent the creature faced prehistoric hyenas and giant crocodilesand endured the frigid wilderness of the Ice Age.

    Lead author Professor Tao Deng said it had a body weight of 24 톤, similar to the total weight of four African elephants or eight white rhinos.

    At the shoulders it as about 16ft hight and 26ft long, with long legs good for running and a head reaching up to a total of 23ft to reach the leaves at the tree top.

    ‘Its prehensile nose trunk was extremely useful to wrap around branchesallowing the sharp front teeth to strip off the leaves,’ said Professor Deng.

    ‘Its tusk-like incisors are primarily used to break twigs and strip bark, as well as to bend higher branches.

    The skull and legs are longer than all reported land mammals, making it suited to open woodlands under humid or arid conditions, according to the study author.

    Paraceratherium was identified from a perfectly preserved skull, jaw and atlasthe first cervical vertebra of the spine that supports the head.

    Giant rhino specimens are scarceand most are fragments. These are among the best foundand help fill an important branch in the beast’s family tree.

    Deng said: ‘It is one of the largest land mammals that ever lived. The giant rhino has primarily been found in Asia. But its evolutionary relationships remain unclear.

    ‘This animal has distinct charactersa slender skull with a short nose trunk and long neck, and a deeper nasal cavity than other giant rhino species..

    Paraceratherium, described in the journal Communications Biology, is closely related to the giant rhinos of Pakistan, suggesting it passed through the Tibetan region.

    ‘From there, it may have reached the Indian-Pakistani subcontinent in the Oligocene epoch between 34 과 23 millions years ago where other giant rhino specimens have been found,’ said Professor Deng.

    The giant rhino is one of the most iconic Ice Age beastswiped out by climate change, disease and human hunting. But its origins are a mystery.

    Deng said: ‘The Tibetan region likely hosted some areas with low elevation, possibly under 6,500ft during Oligocene.

    ‘The lineage of giant rhinos could have dispersed freely along the eastern coast of the Tethys Ocean and perhaps through some lowlands of this region.

    The rock that forms the Himalayas was once submerged by the ancient sea.

    Giant rhino remains found have been found in Eastern Europe, but they mainly lived in China, Mongolia, 두 번째로 총각이 되었을 때, 경고 계속.

    Deng said: ‘During the Oligocene, dispersal for the giant rhino from the Mongolian Plateau to South Asia could have been along the eastern coast of the Tethys like other mammals, such as anthracotheres and ruminants.

    The remains were found within brownish red silty mudstones and sandstones in the Jiaozigou formation in China

    It adds to evidence the Tibetan region was not yet the elevated plateau it is today, without height great enough to deter the giant rhino and other great mammals.

    The possibility is supported by other evidence, including fish and plant fossils that date back to the same period from central Tibet that display tropical characteristics.

    ‘Through to the late Oligocene, the evolution and dispersal of the giant rhino demonstrate Tibet, as a plateau, did not exist and was not yet a barrier to the largest land mammals,’ Professor Deng added.

    Its vertical reach enables it to eat food at the top of the canopyunlike the modern elephant’s method of extending a flexible trunk.

    The arrival of a different kind of herbivore might have triggered ecological changes that helped drive the rhinos to extinction.

    At the time tropical forests were shrinking and grassy savannahs were spreading.

    Rhinos belong to a group of animals called perissodactyls. They have hoovesand an odd number of toes on their rear feet.

    It is believed they first appeared 55 million years ago in Indiawhich at the time was not attached to Asia and perissodactyls were the ancestors of today’s rhinosas well as all modern horses, zebras and tapirs.

    It is not clear why Oligocene rhinos got so big, it may have been a way of coping with the more open grassy habitat.

    SHRINKING SPECIES: EXPERTS PREDICT GLOBAL WARMING WILL CAUSE CREATURES SHRINK

    A recent study in Canada found that over the last century, the beetles in the region have shrunk.

    By looking at eight species of beetle and measuring the animals from past and present they found that some beetles were adapting to a reduced body size.

    The data also showed that the larger beetles were shrinking, but the smaller ones were not.

    주위에 50 million years ago the Earth warmed by three degrees Celsius (5.4°F) 결과적으로, animal species at the time shrunk by 14 퍼센트.

    Another warming event around 55 백만년 전 – called the Paleocene-Eocene Thermal Maximum (PETM) – warmed the earth by up to eight degrees Celsius (14.4°F).

    In this instance, animal species of the time shrunk by up to a third.

    Woolly mammoths were a victim of warming climate, shrinking habitat and increased hunting from a growing early-human population which drove them to extinction - along with many large animals

    Shrinking in body size is seen from several global warming events.

    With the global temperatures set to continue to rise, it is expected the average size of most animals will decrease.

    As well as global warming, the world has seen a dramatic decrease in the amount of large animals.

    So called ‘megafaunaare large animals that go extinct. With long life-spans and relatively small population numbers, they are less able to adapt to rapid change as smaller animals that reproduce more often.

    Often hunted for trophies or for food, large animals like the mastadon, mammoths and the western black rhino, which was declared extinct in 2011, have been hunted to extinction.
