Core reef scutelluid assemblage of the Pragian (Barrandian, Cze) Assemblage 4a (Devonian of Czech Republic)

Where: Czech Republic (49.9° N, 14.1° E: paleocoordinates 41.0° S, 49.9° E)

• coordinate based on political unit

When: Koneprusy Limestone Member, Pragian (410.8 - 407.6 Ma)

Environment/lithology: reef, buildup or bioherm

• ""..the reef core built prevalently of calcareous algae, stromatoporoids, specialized wave-resistant crinoids, and corals, triblobite exoskeletons are contained in lense-like accumulations attaining a thickness of up to 1-2m and traceable for several meters. A layer of brownish microsparite contains the blind trilobite Eodrevermannia sirax, and a white micrite layer contains denemarkia fromtalis with supressed eyes ... these indicate a special light deficient environment in open sedimentary dykes or cavities protected from the coarser bioclastic influx.""
