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).
