Also known as Proetus pulcher Community in E Baltic

Where: Estonia (58.1° N, 22.2° E: paleocoordinates 12.9° S, 1.1° W)

• coordinate based on political unit

• basin-level geographic resolution

When: Uduvere Member (Torgu Formation), Paadla (422.9 - 419.2 Ma)

Environment/lithology: marine; gray limestone

• "Occurs in a gray biosparite with abundant brachiopods of the Didymothyris-Salopina Community, probably representing a shoal position (about BA 2). All trilobite carapaces are disarticulated."

Size class: macrofossils

Collection methods: Trilobites not numerically predominant. Also contains brachiopods, ostracodes, crinoids, stromatoporoids, bryozoans, bivalves, gastropods, and algal structures.
