Where: Guangdong, China (22.2° N, 112.5° E: paleocoordinates 32.3° N, 116.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Lower Member (Jinji Formation), Angulata (201.3 - 196.5 Ma)

• Interpreted as Hettangian by Chen, but ammonites (Sulciferites) in correlative "cycle 2" beds indicate a position low in the Sinemurian according to Wang & Smith (1986). Wang & Smith assign lower member to Hettangian nevertheless (fig. 6) but it is presumably late Hettangian based on its position just below early Sinemurian ammonites.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified siltstone and lithified mudstone

Size class: macrofossils

Preservation: mold/impression

Reposited in the NIGPAS
