This fossil site is located in the Jurassic rocks in the Gobi Desert at Jiangjun Miao, Qitai County, Changji Hui Autonomous Prefecture, Xinjiang Province. Most of the silicified wood is more than 100 cm in diameter, and the largest can reach 200 cm. The wood with a diameter of more than 2 m is estimated to have been at least one thousand years old. The wood fossil pieces or trunks either lie parallel to the ground intact or are broken into segments. There are more than 20 vertical trunks with diameters of 200–250 cm with residual heights of 1–2 m. These petrified wood trunks are mainly of coniferous cypress species as well as ancient spruce, Araucaria, and lush fern bushes. The famous Dinosaur Ditch is located 5 km to the east of this site. Since 1984, six complete dinosaur skeletons have been unearthed at this site. One Mamenchisaurus is 30 m long, 10 m high, and weighed approximately 50 t, which is the largest dinosaur fossil found in Asia and the second largest in the world.
