Dicoelosia-Skenidioides Comm. Grp., Woduhe Fm., Woduhe, Lesser Khingan Mountains (Silurian of China)

Where: China (50.5° N, 125.8° E: paleocoordinates 39.6° N, 52.2° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Woduhe Formation, Wenlock (433.4 - 427.4 Ma)

• Lower part of formation.

• member-level stratigraphic resolution

Environment/lithology: marine; gray, green, yellow sandstone and siltstone

• See lithology. Ref. 7624 assigns formation to BA3 based on shelly fauna.
• No lithologic data given in ref. 7183. Woduhe occurrence simply said to be below a BA 3 Tuvaella gigantea Community, suggesting a shallowing sequence. Ref. 7624 states that Woduhe Fm. "consists of gray-green and yellowish-green, quartzitic sandstone with siltstone interbeds."
