Where: Yunnan, China (25.2° N, 102.1° E: paleocoordinates 33.7° N, 105.7° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Zhangjia'ao Member (Lufeng Formation), Sinemurian (199.3 - 190.8 Ma)
• "Dark Red 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 probable Sinemurian age for the Zhangjiawa Member and a Hettangian age for the Shawan Member.
• bed-level stratigraphic resolution
Environment/lithology: terrestrial; lithology not reported
Size class: macrofossils
Reposited in the IVPP
