Also known as Yunnan, Xiyang, Xiaoheba, Xiaoxiyan, Jin Ji

Where: Yunnan, China (24.5° N, 102.3° E: paleocoordinates 33.7° N, 105.0° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Lower Member (Fengjiahe Formation), Hettangian (201.3 - 199.3 Ma)

• Lower part of formation; equivalent to Lower Lufeng, Shawan Member

•

•The Lufeng Formation has been divided into lower dark/dull purple beds (= Shawan Member) and upper dark/deep red beds (= Zhangjiawa Member). Luo & Wu (1994: In the Shadow of the Dinosaurs, pp. 251–270) argue on the basis of vertebrate biostratigraphy for a probable Sinemurian age for the Zhangjiawa Member and a Hettangian age for the Shawan Member.
