Paleontologists working in China have discovered a new species of giant rhinoceros, the largest mammal ever to have walked on Earth. The giant rhinoceros, Paraceratherium, is found primarily in Asia, according to a press release from the Chinese Academy of Sciences, published Friday. . The new species, Paraceratherium linxiaense, or Linxia Giant Rhino, was named by a Chinese and US team led by Ding Tao of the Academy’s Institute of Vertebrate Paleontology and Anthropology (IVPP), which analyzed fossils found in 2015. “The fossils usually come in,” he said. Ding told CNN “This piece is complete, with a very complete skull and a very complete jaw, which is very rare. The skull was over a meter (3 feet) long, and it was very rare for a skull of this size to be preserved. We also found the cervical spine,” he said. The fossils were found in the Linxia Basin in Gansu Province, northwest China, and genetic analysis showed that it belonged to a new species of giant rhinoceros. Weighe will be 24 tons and was The same size as six elephants, he added that its shoulders were more than 16 feet off the ground, the head was 23 feet high, and its body length was 26 feet, and for comparison, the height of male giraffes may exceed 18 feet, while the height of females is about 14 feet “This is the largest mammal that ever lived on Earth,” said Ding, and lived mainly in China, Mongolia, Kazakhstan and Pakistan, with a few in Eastern Europe, and the giant rhinoceros lived in the northern part of the Tibetan plateau about 31 million years ago. Before migrating southwest to Kazakhstan and then Pakistan, the Lynxia giant rhinoceros descended from those who lived in Pakistan. They had to cross the Tibetan Plateau on their way north to Linxia, ​​which meant that the plateau was lower than it is now, Ding said. In addition, the migration of animals is linked Nat climate change. So 31 million years ago, when he added: “The Mongolian plateau dried up and turned south, then the weather got wet and they returned to the north, so this discovery is of great importance in studying the entire process of uplifting the plateau, climate and environment.” The study was published in Communications Biology, and in September 2020, archaeologists discovered two perfectly preserved craters of a new 125-million-year-old dinosaur species in the Lujiatun Dynasty, the oldest stratum of the famous Yixian Formation in northeastern China. Scientists believe that the burrowing dinosaur, Changmiania liaoningensis, was trapped by a volcanic eruption while resting at the bottom of its burrows.

Paleontologists working in China have discovered a new species of giant rhinoceros, the largest land mammal ever to walk the earth.

The giant rhinoceros, Paraceratherium, is found mainly in Asia, according to a press release from the Chinese Academy of Sciences, published Friday.

The new species, Paraceratherium linxiaense, or Linxia Giant Rhino, was named by a Chinese and US team led by Ding Tao of the Academy’s Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), which analyzed the fossils found in 2015.

“Fossils usually come in pieces, but this fossil is complete, with a very complete skull and a very complete jaw, which is very rare,” Ding told CNN.

“The skull was more than a meter (3 feet) long and it was very rare to preserve a skull of this size. We also found the cervical spine,” he said.

The fossils were found in the Linxia Basin in northwest China’s Gansu Province, and genetic analysis showed that they belonged to a new species of giant rhinoceros.

Ding told CNN that the huge animal weighed 24 tons and was the size of six elephants. He added that his shoulders were more than 16 feet off the ground, the head at 23 feet, and his body length was 26 feet.

For comparison, male giraffes may exceed 18 feet in height, while females reach around 14 feet.

“This is the largest mammal that ever lived on Earth,” Ding said.

Linxia giant rhinoceros is a new species.

He added that they mainly live in China, Mongolia, Kazakhstan and Pakistan, with a few in Eastern Europe.

The giant rhinoceros lived in the northern part of the Tibetan plateau about 31 million years ago, before migrating southwest to Kazakhstan and then Pakistan.

The Lynxia giant rhinoceros descended from those who lived in Pakistan. Deng said that they would have had to cross the Tibetan Plateau on their way north to Linxia, ​​which meant that the plateau was lower than it is now.

“In addition, the migration of animals is associated with climate change. Therefore, 31 million years ago, when the Mongolian plateau dried up, they moved to the south,” he added.

“Then the weather got wet and they returned to the north. Therefore, this discovery is of great importance for studying the entire process of uplifting the plateau, the climate and the environment,” he said.

The study was published in the journal Communications Biology.

In September 2020, archaeologists discovered two perfectly preserved craters of a new 125 million-year-old dinosaur species in the Lujiaton family, the oldest layer of the famous Yixian Formation in northeastern China.

Scientists believe that the burrowing dinosaur, Changmiania liaoningensis, was trapped by a volcanic eruption while resting at the bottom of its burrows.
