Rhynchotreta cuneata-Atrypoidea linguata Comm., Wenlockian, C. Urals (Silurian of Russian Federation)

Where: Russian Federation (56.0° N, 60.0° E: paleocoordinates 4.2° S, 13.4° E)

• coordinate based on political unit

• local area-level geographic resolution

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

• "Middle and possibly the earliest Late Wenlockian"

• formation-level stratigraphic resolution

Environment/lithology: marine; gray limestone and calcareous sandstone

• Shells both articulated and disarticulated. "Moderately quiet water, level bottom, firm to soft substrate, BA 3, or possibly 2."
• "Occurs in dark-gray, medium-bedded (15-20 cm. thick), organogenic limestones of the Kabanka Beds (interbedded limestone, calcareous sandstone and aleurolites; total thickness about 40 m).

Collection methods: Table 41.7 gives abundances for brachiopods and trilobites at type locality.
