Also known as Dawa
Where: Yunnan, China (25.2° N, 102.1° E: paleocoordinates 33.8° N, 105.8° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Zhangjia'ao Member (Lufeng Formation), Sinemurian (199.3 - 190.8 Ma)
• 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. It is not clear which member this collection comes from.
