Where: Ukraine (48.9° N, 26.2° E: paleocoordinates 18.4° S, 7.0° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Varnitsa Formation, Pridoli (423.0 - 419.2 Ma)

• Middle part of Varnitsa "suite", Rukshin "series" (Skalian "superhorizon"). See fig. 38.1 for correlation chart.
