Where: Yunnan, China (25.0° N, 101.5° E: paleocoordinates 22.3° N, 100.2° E)

• coordinate based on nearby landmark

When: Jiangdihe Formation, Turonian to Turonian (93.9 - 83.6 Ma)

• Jiangdihe Formation, Upper Cretaceous (Turonian–Santonian) (Chen, 2000).

•The litho- and biostratigraphic correlation performed by the regional geological survey suggests that the Jiangdihe Formation was deposited during the Late Cretaceous (Y. Zhang, 1996), a conclusion corroborated by evidence from fossil invertebrates (conchostracans: e.g., Aglestheria, Halysestheria, Nemestheria; ostracods: e.g., Cypridea, Limnocythere) and palynomorphs that indicate the formation is Turonian–Santonian in age (Chen, 2000).

•The Jiangdihe Formation is conformable with both the underlying Matoushan Formation and the overlying Zhaojiadian Formation.

• formation-level stratigraphic resolution

Environment/lithology: lacustrine - large; sandy mudstone

Size classes: macrofossils, mesofossils

Preservation: soft parts

Collected by Guanghui Xu in 2010; reposited in the IVPP

• The skeleton was collected by one of us (G.X.) in 2010 from the Jiangdihe Formation at Luojumei Village, Chuxiong City, in Yunnan Province, southern China
