BEIJING, April.20 (Xinhuanet) -- China's biggest
fossil reserves, in Northeastern Liaoning Province, need urgent protection,
warned a paleontologist from the Chinese Academy of Sciences (CAS).
"The western part of Liaoning Province that yields many rare fossils is in great danger because of the rampant
private fossil excavation and smuggling," said Wang Xiaolin, researcher from the
CAS Institute of Vertebrate Paleontology and Palaeoanthropology (IVPP).
"The situation is very, very serious at present.
Nearly each possible site has been dug," said Wang, who is in charge of fossil
exploration in Liaoning and has inspected the region frequently during the past
seven years.
A group of fossils found in western Liaoning Province
which include Confuciusornis, the earliest bird found in the world to date with
a beak. Liaoning bird, the oldest ancestor of modern birds, was also found in
the area.
The fossils provide rare evidence for the study of
primitive birds and other living things as well as reconstruction of ancient
environment.
Some experts believe the region could be the place of
origin of some fishes and insects.
"Thanks largely to remarkable discoveries here, most
paleontologists now agree that birds share a common ancestry with dinosaurs, in
particular with small carnivores called dromaeosaurs," said a source from
"Nature" magazine's web edition.
However, those treasures are in great danger.
Fossil smuggling in the western part of Liaoning has
intensified and many precious fossils have been smuggled outside.
Chaoyang city, which houses abundant fossil
resources, is now covered with signs of activities left behind by local
farmers.
A professor from the Beijing-based Capital Normal
University found many valuable insect fossils scattered around.
Experts believe handsome profit drives farmers to go
searching for fossils while lax administration gives local farmers an invitation
to engage in fossil trading and smuggling. Some bird and mammal fossils could
fetch a price equal to that of one building.
Shenyang customs cracked down on a fossil smuggling
case in 2002 involving more than 2,300 fossils. Some of them were originally
identified as second-class fossils.
"Many of the fossils in foreign shops and museums are
from Liaoning," said Ren Dong from Capital Normal University.
Simple Internet search results back his word.
There are many Liaoning fossils for trade on net.
Zhou Zhonghe, from the CAS, estimated that hundreds
of Confuciusornis fossils may have been smuggled outside China since 1990.
About 1,000 such fossils have been found in China in
the past decade. But only a small part now are in institutes and museums. Most
have been smuggled to Japan, Germany and the United States, said Zhou.
The local government has moved to strengthen fossil
management. Some fossil markets have been set up in Chaoyang, Jinzhou and Fuxin
to counter illegal fossil trading.
"All fossil dealers have moved into the specific
market. We have a special office in charge of fossil trading. Only three types
of fossils can be sold," said Ding Guifu, vice-director of Chaoyang's Land and
Resources Bureau.
But experts argue that such fossil markets have eased
problems but not solved them.
"I absolutely disagree with such a market. So-called
legal fossil trading leads to the rampant private digging. Because if you want
to trade, you must find the goods first," said Wang.
Some experts said they thought the regulations were
not complete.
"The regulations do not pay enough attention to
fossil protection," said Zhou Zhonghe, a researcher from the CAS.
"What we found is only a small part. The rest in the
earth may be more important. It demands immediate salvation," said Zhou.
