South of Dahuangtian Village (Jurassic of China)

Also known as Huangchiatian

Where: Yunnan, China (25.2° N, 102.1° E: paleocoordinates 33.8° N, 105.8° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Zhangjiawa 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.

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils

Collected in 1980; reposited in the IVPP
