Scientists have unearthed a large dinosaur fossil site in southwestern China.
Paleontologists say 5,000 dinosaur fossils have been excavated from a "fossil wall". The wall is 150 meters long, eight meters high and two meters thick.
Officials say this is the largest fossil wall in the world. Experts believe that a great number of dinosaur fossils are still buried at least 20 meters under the ground.
The discovered fossils belong to five dinosaur categories and date back to the Jurassic period.
