Loc. 5.4, Muslovka Quarry, sect. 687, lower bioclastic Lsts (beds 1-16) (Silurian of Czech Republic)

Where: Czech Republic (50.0° N, 14.3° E: paleocoordinates 48.2° S, 54.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kopanina Formation, Ludfordian (421.3 - 418.7 Ma)

• Several key fossils occur through section, but zonation does not appear clear enough to allow unambiguous assignment.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; pyritic, shelly/skeletal, gray limestone and concretionary, calcareous shale

• "...135 cm thick massive bank of light grey bioclastic limestone...overlain by 140 cm grey calcareous shales with grey bioclastic limestone concretions...ten horizons of dark grey bioclastic brachiopod limstone...overlain by 285 cm of massive light grey bioclastic cephalopod limestone...next, 70 cm thick bank of massive grey bioclastic limestone with abundant pyrite..."
