Huangshiban, Weiyuan (Jurassic to of China)

Where: Sichuan, China (29.6° N, 104.7° E: paleocoordinates 30.6° N, 109.8° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Maanshan Member (Ziliujing Formation), Aalenian to Aalenian (174.1 - 168.3 Ma)

• The Ziliujing is divided into (in ascending order) Zhenzhuchong, Dongyuemiao, Ma’anshan, and Da’anzhai members. A Toarcian age for the Dongyuemiao Member and an early Middle Jurassic age for the overlying parts of the formation is supported on the basis of macroplants (e.g. Meng et al. 2003. Acta Palaeontologica Sinica 42: 525-536)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; red, blue mudstone

• "purple mudstones"

Size class: macrofossils
