Loc. 2.4, Cephalopod Quarry, Lochkow, sect. 407, unit 5 (Silurian of Czech Republic)

Where: Czech Republic (50.0° N, 14.3° E: paleocoordinates 51.0° S, 56.8° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Ozarkodina crispa conodont zone, Kopanina Formation, Ludfordian (425.6 - 423.0 Ma)

• Uppermost Kopanina. PJW: That would be Ozarkodina crispa zone.

Size class: macrofossils

Preservation: mold/impression
