Dicoelosia paralata-Skenidioides sp. Community, Podolia (Silurian to of Ukraine)

Where: Ukraine (48.7° N, 26.8° E: paleocoordinates 28.3° S, 6.9° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Llandovery to Llandovery (443.4 - 427.4 Ma)

• Teremetsy member, Bolotino "series" and the Restevo and Demshin "subsuites" fo the Yaruga "series". See fig. 38.1 for correlation chart.

Environment/lithology: marine; argillaceous marl and argillaceous limestone

• "[Articulation of specimens] suggests that they lived in a quiet water environment. High diversity agrees with this conclusion. In light of sedimentological model developed by many Estonian workers, it is concluded that in Podolia, as well, the outer subzone of the open shelf and the inner part of the platform shelf were the environment occupied by this community, i.e. seawards of the outer boundary of the reef building zone. Assigned to BA 4."
• "A high percentage of articulated brach's preserved in dark, argillaceous marls and fine-grained argillaceous limestones..."

Collection methods: Counts are given for brachiopods.
