Workers have spent three years building a huge earth dam to
protect valuable dinosaur bones from being washed away by one of
China's most famous rivers.
A cache of dinosaur bones lies buried in a mountain that sits
right on the river that forms the boundary between China and Russia
- the Heilongjiang River.
So far, thousands of dinosaur fossil bones have been unearthed
from the mountain and assembled into 13 dinosaur skeletons that are
now exhibited in several museums nationwide.
Archaeologists believe there are enough fossil bones buried in
the mountain to put together at least 100 more dinosaur skeletons.
Every summer, rising waters and strong currents erode parts of the
mountain, leaving dinosaur fossils exposed, and many fossils have
been washed away in the past.
To prevent this from happening, the Land and Resources
Department of Heilongjiang Province ordered the construction
of a 1,450-meter-long embankment on the Chinese side of the river
to stop the fossils from being washed away.
Building the embankment has been difficult, with workers
battling cold and long winters at a high altitude in China's
northernmost province. Rising water levels in the summer also limit
construction, and it has taken workers three years to complete the
1,450-meter-long, 5.5-meter-high, and 10-meter wide embankment
around the dinosaur fossil site.
"The embankment could effectively protect the Dinosaur Mountain
from threats of water erosion and floods, thus, the dinosaur
fossils are rescued from being washed away," said Li Jinshan, vice
director of Jiayin Dinosaur National Geologic Park Administrative
Bureau.
Dinosaur Mountain, which used to be called Mountain of Dinosaur
Bones, is inside Jiayin Dinosaur National Geologic Park at Jiayin
County, northeast China's Heilongjiang Province.
