Where: Yunnan, China (25.2° N, 102.1° E: paleocoordinates 34.4° N, 104.6° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Shawan Member (Lufeng Formation), Hettangian (201.6 - 196.5 Ma)
• "Dull Purplish beds of the Lower Lufeng Formation"
•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 Hettangian–Sinemurian age for the Zhangjiawa Member and a Hettangian age for the Shawan Member.
