JINAN - Chinese archaeologists have again unearthed several dinosaur fossils at a site in Laiyang city, in East China's Shandong province.

More than 130 fossils, including bone and egg remains, were unearthed at the excavation site near the village of Jingangkou, according to sources with the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences.

Scientists sealed off the fossils and surrounding rock with gypsum for further restoration and research, said Wang Xiaolin, a researcher with the institute who is in charge of the excavation.

"Most of the fossils are relatively intact, and this is favorable for assembly of a complete dinosaur skeleton," Wang said.

The largest piece of fossil, the remains of a humerus, or upper arm bone, is over 60 cm, Wang said.

Fossils were first found here in 2010, and scientists have already unearthed several dinosaur remains from at least 20 fossil-bearing layers.

In 2011, Laiyang was approved as a national park for dinosaur fossils.
