Jiufotang Formation

The Jiufotang Formation dates back to the Aptian Age of the Early Cretaceous. The area was very swampy 120 million years ago, that is until it was covered by volcanic ash. Fossil-rich exposures are located in Chaoyang, Liaoning, China.

Beautiful artwork depicting what the environment and some of its creatures may have looked like can be found on the Pteros website.
