The Yunyang On-site Dinosaur Fossil Protected Shelter in southwest China's Chongqing recently opened, unveiling the world's largest Jurassic dinosaur fossil wall. The fossil wall is about 150 meters in length, between 6 and 10 meters in height, and in a stepped layout. With an exhibition area of about 1,320 square meters, the wall displays nearly 5,000 pieces of fossils, covering skulls, teeth, vertebrae, limb bones, girdles and other skeletal parts.
