Dicoelosia-Skenidioides Comm., Paprieniai Fm., Grauzai-105 Borehole (777.1 m) (Silurian of Lithuania)

Where: Lithuania (55.2° N, 23.9° E)

• Paleocoordinates: 4.9° S, 44.4° W (Wright 2013)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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

• bed-level stratigraphic resolution

Environment/lithology: marine; gray, green, argillaceous marl and lime mudstone

• "The fauna belongs in the BA 4-5 span, and is here positioned in BA 4. [Shells predominantly disarticulated, but not exclusively.] The articulation data indicates a normal level of turbulence consistent with a normal oxygen level."
• "Occurs in greenish, argillaceous marls and in greenish-gray marls with interbeds of microcrystalline linestone of the fourth facies zone."

Collection methods: Brachiopods listed (with abundances) in table 21.5.
