Where: Yunnan, China (25.2° N, 102.1° E: paleocoordinates 34.4° N, 104.7° E)
• coordinate based on nearby landmark
• hand sample-level geographic resolution
When: Shawan Member (Lufeng Formation), Hettangian (201.3 - 199.3 Ma)
• Lufeng Mesozoic Sediments divided into Lower and Upper Series. Units 1-4 in Lower Series, Units 5-8 in Upper Series.
•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.
• bed-level stratigraphic resolution
Environment/lithology: terrestrial; poorly lithified, concretionary, green, red, blue, calcareous claystone
Size classes: macrofossils, mesofossils
