World Fossils of rhino taller than a giraffe found in China
Can China still lead the world in tech without a new Jack Ma?
China has cut its global tech champions down to size, cracking down on antitrust abuses and undue risk taking. But the heavy-handed approach could backfire on Beijing by stifling an entrepreneurial spirit that has proven vital to the country's rapid economic rise.Several tech companies have been investigated in the past few months over alleged monopolistic behavior or other breaches of consumer rights. The ongoing probe — which President Xi Jinping has personally endorsed as necessary to maintain "social stability" — has led to record fines for some tech titans and massive overhauls for others. More than $600 billion has been wiped off the value of the biggest tech stocks in recent months.
Today’s Tibetan Plateau reaches into the sky—a craggy expanse of high-altitude steppes butting up against the towering Himalaya. But 26.5 million years ago, parts of this region were dotted with humid woodlands, giving refuge to another kind of skyscraper: one of the biggest mammals to ever walk on land.
The newfound creature, unveiled today, is an extinct cousin of today’s rhinoceros called Paraceratherium linxiaense. The colossal animal would have weighed up to 24 tons, four times heavier than today’s African elephants, and its skull alone was more than a yard long.
Dinosaur species among largest in the world discovered in Australia
Scientists confirmed the finding of a new species of dinosaur, Australotitan cooperensis, that was one of the largest in the world, study says.In a report published in the journal PeerJ on Monday, scientists confirmed the finding of new dinosaurian fossils that came from a titanosaurian sauropod.
It’s the latest known species in a group of giant, hornless rhinos that lived across Central Asia from roughly 50 million years ago until 23 million years ago. P. linxiaense and its kin are all famous for their huge sizes. The average adult is thought to have stood more than 16 feet tall at the shoulder, with a nearly seven-foot-long neck topped by a massive skull. Today’s giraffes are, head and all.
The giant rhinos “would have been able to eat flowers at the third or fourth floor of a building,” says National Geographic Explorer, a rhino paleontologist at France’s University of Montpellier who reviewed the new study.
P. linxiaense was among the last of these giants, called paraceratheres, living about 26.5 million years ago. Thanks to their age and location, the new fossils, including a complete skull, a mandible, and three vertebrae, are helping fill out the paracerathere family tree, shedding new light on where these towering rhinos evolved and how they spread across the present-day continent of Asia.
Fact check: Did a company 3D-print rhino horns to help slow down poaching? Yes, but it didn't last long
A company started manufacturing fake rhino horns in 2015 to stop the illegal poaching of the animal.One widespread social media post claims a biotech company found the solution.
A prehistoric giant
Paraceratherium fossils are rare and often fragmentary, making it hard to chart the genus’s evolution and spread. The group’s longtime home appears to have been Central Asia, but the first species of Paraceratherium ever found, P. bugtiense, lived in what is now western Pakistan. How exactly did this giant rhino get all the way to the Indian subcontinent?
Researchers led by, a mammal paleontologist at China’s Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, have now found that the new species P. linxiaense was closely related to the Pakistani P. bugtiense, and that hints at the Pakistani rhino’s origins.

The new fossils hail from the brown sandstones of central China’s Linxia Basin. Here, sediment layers up to 1.2 miles thick tell the story of the last 30 million years of Earth’s history, peppered with fossils from the ancient creatures that once lived in the region.
This YouTube Fossil Hunter Has Dug up Thousands of Ancient Animals
The YouTuber, who has found hundreds of tiny shark teeth and several whale skulls, began posting videos on his channel Mamlambo Fossils two years ago.The YouTuber began posting videos to the site on his channel Mamlambo Fossils two years ago, most of which show him carefully excavating and preparing fossils that he has found.
In the 1950s, farmers in the area claimed to have found “dragon bones.” For a time, these remainsand used as ingredients in traditional Chinese medicines. By the 1980s, paleontologists recognized that the region preserved scientifically valuable fossils from the late Oligocene epoch, the time period 23 to 28 million years ago.
Ever since, paleontologists with the Institute of Vertebrate Paleontology and Paleoanthropology have studied the Linxia Basin’s rocks and the rich array of fossils they contain.
In May 2015, Deng and his colleagues came across a rare find near the village of Wangjiachuan: the complete skull and mandible of a giant rhinoceros, as well as three vertebrae from another individual. When the researchers saw the 26.5 million-year-old bones—including the 3.8-foot-long skull—their preservation and size came as “a great surprise to us,” Deng says.
Based on its similarities to the giant rhino from Pakistan, the new findings suggest that giant rhinos moved freely across thousands of miles between Central Asia and the Indian subcontinent between 30 and 35 million years ago. Tropical conditions at the time “allowed the giant rhino to return northward to Central Asia, implying that the Tibetan region was still not uplifted as a high-elevation plateau,” Deng writes in an email—an idea that is.

Mysteries of the giant rhino
Antoine, the French paleontologist, says the new study helps reveal geographic patterns that governed the giant rhinos’ movements across ancient Earth. A catalog of giant rhino fossils in the new research suggests that the animals never crossed from Asia into Europe through the Ural Mountains, for example, indicating the mountain range may have acted as a barrier.
The research may also help explain how the huge creatures arrived in what’s now Turkey, where fossils of the rhinos have also been found. According to Antoine, fossils that have not yet been described in a scientific paper suggest that after giant rhinos arrived in present-day Pakistan, they made their way into Turkey across what is now Afghanistan and Iran.
Some of the fossils that tell this story, however, are now lost to science. A collection of 300 fossils that Antoine helped collect in Pakistan—including giant rhino remains—, when the Pakistani army bombed Dera Bugti, a town in the western Balochistan Province, as part of . That same year, the powerful chieftain and Baloch leader Nawab Akbar Bugti during a standoff with the Pakistani military. Bugti had been a key contact, and source of protection, for paleontologists working in the region.
In P. linxiaense’s case, the fossils are secure in the Hezheng Paleozoological Museum in China’s north-central Gansu province. Deng has high hopes for future studies of the remains, including a reconstruction of the creature’s muscles and a more refined estimate of its body mass.
He adds that since researchers now have evidence of giant rhinos crossing the present-day Tibetan Plateau, there may be more fossils to find in the region—a skyscraper of an animal, interred in what is now the roof of the world.
