Also known as Laochangjing, A'na; Konglongshan; Laochangqing; Ana Village; A’na village

Where: Yunnan, China (25.0° N, 102.1° E: paleocoordinates 25.1° N, 108.6° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Chuanjie Formation, Bajocian (170.3 - 168.3 Ma)

• From the base of the Chuanjie Formation, which was regarded to be Middle Jurassic (Bajocian), according to the magnetostratigraphic study of Huang et al. (2015).

• playa lakebed
• purplish red silty mudstones

Size classes: macrofossils, mesofossils
