InGen Database Description
The Ziliujing Formation is a sub-unit of the Dashanpu Formation in China and located in the Zigui Basin. The site was first discovered to contain fossils in the 1970s and it dates back to the Middle to Late Jurassic epochs, 168 million years ago.
An assemblage of 300 theropod and sauropod footprints were found in a region of what was likely to have been a tropical freshwater lake. In 1977 a dinosaur specimen was extracted that could be a possible evolutionary link between prosauropod and sauropod.
The region was once a dense forest and likely contained a large river that fed into a lake.
Fossils including amphibians, turtles, marine reptiles and fish were discovered here.
