Chinese scientists unearthed the largest fossil of a Stegosaurus' shoulder bony plate in the dragonValley of Xingjiang Uygur Autonomous Region, according to the  Xinhua  news agency.  

Wang Haijun, an engineer at the Chinese Academy of Sciences, said two important discoveries were not made public during CCTV's live broadcast of the fossil excavations on Saturday.

The fossil stegosaurus shoulder plate found in Pit 2 was one of them. It measures 1.37 meters, compared to the second largest speciment of 1.2 meters found in Sichuan.

Two fossil fragments suspected to come from dinosaur heads were also found in Pit 1, measuring 50 centimeters by 17 centimeters. The scientists will rehabilitate the fossil to determine what part of the animal they came from.

While Doctor Xu Xing confirmed that the should plate fossil is the largest one found so far in the world, it not necessarily mean they had discovered the world's largest stegosaurus.
