Woduhe Fm. (T. gigantea Beds) on River Woduhe, Nenjiang Co., Heilongjiang Prov. (Silurian to of China)

Also known as Woduhe Fm. (Tuvaella gigantea Beds)

Where: Heilongjiang, China (51.0° N, 125.0° E: paleocoordinates 41.1° N, 50.9° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Woduhe Formation, Wenlock to Wenlock (433.4 - 423.0 Ma)

• Except where otherwise stated, ref. 7624 uses Lower Silurian as equivalent to Llandovery, Middle Silurian as equivalent to Wenlock, and Upper Silurian as equivalent to Ludlow plus Pridoli. Fossils in underlying beds indicate "an age no older than Late Wenlock" (assigned to Late Wenlock in PBDB coll. 25760). Correlation chart indicates Upper Silurian.

• member-level stratigraphic resolution

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

• Correlation chart indicates BA3 based on shelly fauna.
• "consists of gray-green and yellowish-green, quartzitic sandstone with siltstone interbeds. The formation has a thickness of 370 m"

Collection methods: See PBDB coll. 25760 for another collection from this formation (below this one).
