Qishuihe outcrop, Hejiafang, Jinsuoguan Town, Tongchuan City (Triassic of China)

Where: Shaanxi, China (35.2° N, 109.0° E: paleocoordinates 39.5° N, 87.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Yanchang Formation, Longobardian (242.0 - 235.0 Ma)

• Fossils come from Upper part of Lower Member of Tongchuan. Ash beds from within the insect-bearing units dated at 238.0 and 237.4 Ma, indicating latest Ladinian age (Zheng et al., 2018). Most authors have indicated that the Tongchuan Formation should be abolished as it has no distinctive lithostratigraphic criteria by which it can be separated from the Yanchang Formation.

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine; lithified, gray, green mudstone

• Grayish-green mudstone

Size class: mesofossils

Preservation: mold/impression

Reposited in the NIGPAS
