The Jiufotang Formation (Chinese: 九佛堂组; pinyin: jiǔfótáng zǔ) is an Early Cretaceous geological formation in Chaoyang, Liaoning which has yielded fossils of feathered dinosaurs, primitive birds, pterosaurs, and other organisms (see Jehol Biota). It is a member of the Jehol group. The exact age of the Jiufotang has been debated for years, with estimates ranging from the Late Jurassic to the Early Cretaceous. New uranium-lead dates reveal the formation is deposited in the Aptian stage of the Early Cretaceous.[2] Fossils of Microraptor and Jeholornis are from the Jiufotang.[3]
