Prionopeltis archiaci-Atrypoidea modesta Community, Prague Basin (Silurian of Czech Republic)

Where: Czech Republic (49.5° N, 13.5° E: paleocoordinates 51.7° S, 56.7° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Kopanina Formation, Ludfordian (425.6 - 423.0 Ma)

• Upper Kopanina, Late Ludlow.

• formation-level stratigraphic resolution

Environment/lithology: marine; shelly/skeletal limestone

• "According to Horny (1955) the Kopanina Fm. consists of two major sed. cycles, each terminatin with a marked shallowing...The earlier one, corresponding to the lower Kop., closed with the shallow subtidal Atrypoidea linguata Comm. and its equivalents. The later cycle (i.e., upper Kop. in our concept) closes with the shallow watet P.a.-A.m. Comm, which roughly corresponds with Horny's P. archiaci Horizon...We conclude that the Comm. occupied a BA 3, quiet water environment..."
• "...confined to organodetrital limestones with abundant vagrant and sessile benthos. The uppermost layers commonly consist of orthocone nautiloid accumulations."

Collection methods: Authors give relative abundance data for brachiopods.
