Chinese researchers said the fossil structure of the hadrosaur was about 8 meters long, 1 meter wide and 5 meters tall. It was a mature dinosaur that lived 80 million years ago.

Ten workers are restoring the fossil in a storehouse in Chengguan town, Bayannur city. The work began in May this year and is expect-ed to end in October.

Such a complete dinosaur fossil is a very rare find, said Xu Xing, a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology under the Chinese Academy of Sciences.

It will greatly inform research into the evolution of the hadrosaur species and biology in the Rehe area, he said.

Archaeologists also found fossils of other plants and living organisms in the Rehe area, which will prove invaluable in future research.
