Encrinurus (E.) punctatus Comm. in E Baltic (Silurian of Estonia)

Where: Estonia (58.1° N, 22.2° E: paleocoordinates 16.2° S, 1.1° W)

• coordinate based on political unit

• basin-level geographic resolution

When: Jaagarahu (428.2 - 422.9 Ma)

• "Jaani and probably Jaagarahu Stages"

Environment/lithology: marine; calcareous mudstone

• "Occurs in slightly nodular, calcareous mudstones which a re interpreted as relatively quiet water environments occurring in the transition from the open shelf to the slope facies belt. Articulated [i.e. valves joined, not "Articulata"] brachiopods and trilobite carapaces are common. The community is consistent with an outer BA 3-4 assignment as suggested by the associated brachiopod units."

Collection methods: Assemblage found with brachiopods, gastropods, and corals (among others). Some brachiopods and corals mentioned by name; these are included in list.
