Where: Yunnan, China (25.7° N, 104.1° E)

• Paleocoordinates: 38.1° N, 124.4° E (Wright 2013)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Zhangjia'ao Member (Lufeng Formation), Sinemurian (199.5 - 192.9 Ma)

• "Dark Red Beds"

•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
