Loquanjing, Luanshai (Jurassic to of China)

Also known as Luochuanjing

Where: Sichuan, China (29.8° N, 104.9° E: paleocoordinates 30.9° N, 110.0° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Daanzhai 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 and gray, white limestone

• from a "purple-red mudstone" above the Daanzhai Member, which is a "gray-white freshwater limestone"

Size class: macrofossils

Collected in the 1980s; reposited in the IVPP
