China Post: China leads the world in dinosaur discoveries

KANSAS CITY, Mo. -- Lost in time, hidden beneath the earth for millions of years, dinosaurs aren't creatures that reveal their secrets quickly.
 

Yet two new and surprising dino-discoveries recently have come out of the University of Kansas (KU). Not surprising, both have emerged from fossils found in a nation that in the past decade has risen to utterly transform the study of the prehistoric past.

More than ever, this is the age of the Chinasaurs.

“Whether you are looking for marine reptiles or birds or dinosaurs, or whatever, China is developing so fast right now it is staggering.” said Philip Currie, professor of dinosaur paleobiology at the University of Alberta and vice president of the Society of Vertebrate Paleontology. “I'd say that right now it is number one in the world for most major fossil finds.”

The first KU discovery, announced in December, looks at fossilized teeth of a turkey-sized dinosaur to show that some meat-eating dinosaurs not only clawed or chomped their victims, but also oozed venom from glands in their mouths like cobras or Komodo dragons to poison their prey.

The second finding, published last week in the Proceedings of the National Academy of Sciences is sure to reignite the ongoing fight over the origin of flight.

Paleontologists, David Burnham and Larry Martin, and animal flight expert, David Alexander — all with KU — worked with Chinese scientists to create a model using bones cast from a 125-million-year-old, four-winged gliding dinosaur named microraptor to show that the pheasant-sized critter probably did not run on the ground, as many scientists contend.

The scientists instead present evidence suggesting that the sharp-toothed carnivore, an ancestor of modern birds, always lived in the trees, spreading its wings and coasting from branch to branch.

The paper is a direct challenge to the “ground up” notion of flight, the theory that modern birds evolved from feathered dinosaurs that first ran on the ground before evolving the ability to take wing.

“With 7-inch flight feathers on its feet, it was implausible that it would even walk,” Burnham said.

To be sure, for nearly 130 years ever since the late 1870s, when great long-necked dinosaurs were discovered in the American West — the United States (U.S.) reigned supreme as the site of new dinosaur discoveries. But in the past five years, China has usurped North America in a dino-race that, to the extent it exists, is as collegial as it is competitive.

In fact, one of the most important figures in China paleontology, 45-year-old Zhonghe Zhou, the director of the Institute of Vertebrate Paleontology and Paleoanthropology, happens to be a KU grad. He earned his doctorate there in 1999.

“We now have three people here from KU,” Zhou said in a telephone conversation from Beijing. “One guy on my team, he's an expert on fossil amphibians. He got his master's degree there.

“When I was at KU, I was really interested in sports. I watched all the basketball games. Even when I come back, I still pay attention to KU.”

In paleontology — whether the focus is dinosaurs, prehistoric mammals, 500-million-year-old sea creatures or even early humans — China is now ranked first among fossil-hunting sites.

“It's not just dinosaurs, but fossil mammals, too,” said famed dinosaur hunter, Bob Bakker, curator of the Houston Museum of Natural Science. “They have great stuff: complete saber-tooth cat skeletons, three-toed horses. The Chinese have magnificent fossil rhinos.”

As far as dinosaurs go, University of Pennsylvania paleontologist, Peter Dodson, keeps a running tally of the number discovered in different countries.

“I knew China had been close to the U.S.,” he said. “I discovered to my surprise, chagrin, amazement that as of last summer, China not only had already surpassed the U.S., but shot past it. I honestly didn't think we would ever relinquish our position, but things have happened so fast in China.”

As of 1990, for example, a total of 64types of dinosaurs had been found in the U.S; 44 in Mongolia; 36 in China.

In 2006, the U.S. hit 108, China was second at 101, Mongolia had 61.

Today: 132 have been found in China, 108 in the U.S. and 65 in Mongolia.

“I had a Chinese graduate student,” Dodson said of his former student, You Hai-Lu. “In 2003, he accomplished a feat that nobody in the history of dinosaur paleontology had done. He named five new dinosaurs in one year.”

Some 365 new dinosaurs have been discovered and named in the last 20 years alone, more than in the previous 130 years. About 650 types are now identified, with an average of 25 new ones found each year.

To be sure, China has a rich history of paleontological finds going back to the 1920s and the work of C.C. Young, a famed Chinese paleontologist educated in Germany. The “Peking Man,” an early example of homo erectus, believed at the time to be about 500,000 years old, was found near Beijing in 1923. Studies in 2009 by Chinese and American researchers now suggest that those fossils may be 250,000 years older than originally thought.

But the more recent finds are the result of vast fossil deposits being unearthed from at least nine major sites across China. The creatures ranging from 100-foot-long sauropods to the feathered birds studied at KU represent every major dinosaur period.

From Yunnan Province in the south come Triassic species, 248 million to 208 million years old. Huge Jurassic types, 208 million to 146 million years old, emerge out of Xinjang in the west. Liaoning Province, in northeast China, produces countless Cretaceous creatures, 146 million to 65 million years ago — including a treasure trove of feathered fossils.
