Two well-preserved dinosaur fossils dating back approximately 130 million years were recently unearthed in north China's Hebei Province, according to local authorities on Thursday.

Both of the discoveries were herbivorous dinosaurs, and they were found in Fengning Man Autonomous County within the city of Chengde, according to a press briefing by the provincial department of natural resources.
The larger fossil belongs to a stegosaurus and is a near-perfect preservation of its skeleton and skin.
Measuring about 5 meters in length, the stegosaurus fossil is nearly complete at the Fengning fossil conservation research center.
It includes four tail bone spurs that are highly recognizable and its skeleton is accompanied by intact fossilized skin. The pattern of the skin, similar to what can be seen on snakes or lizards today, is incredibly distinct and clear.
"As we can see, the black and white parts are remnants of skin, and there may be some covering bones as well. The preserved area or proportion of skin is very large. The condition of this fossil is very rare in the world," said Pei Rui, associate researcher at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences.
The nearly complete skin will provide key evidence to reveal the body surface characteristics, physiology and habits of stegosaurus dinosaurs, Pei said.
In addition, gastroliths are identified in the abdomen area.
"The gastroliths are preserved. They can help digest food, and allow us to make valuable speculations about the life of the dinosaurs at that time," Pei said.
The other fossil has been attributed to the more primitive ceratosaurus, filling a gap in the evolutionary history and development of the ceratosaurus. The preservation is also quite remarkable. Its hind limbs were obviously longer than its forelimbs.
