Yanliao Biota
The Yanliao Biota is the name given to an assembly of fossils preserved in northeastern China from the Middle to Late Jurassic. It includes fossils from the Tiaojishan Formation, Lanqi Formation, Jiulongshan Formation and Haifanggou Formation. This spans approximately 199 to 146 million years ago.

Like the Jehol Biota, these deposits are composed of alternating layers of volcanic tuff and sediment, and are considered Lagerstätte. These are some of the best preserved Jurassic fossils in the world, and include many important dinosaur, mammal, salamander, insect and lizard specimens, as well as plants.
