Eurypterid-Associated Biota of the Chortkov Horizon in Podolia (Devonian of Ukraine)

Where: Ukraine (48.6° N, 25.7° E: paleocoordinates 47.6° S, 75.3° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Chortkov Formation, Lochkovian (419.2 - 410.8 Ma)

• Chortkov Horizon (Zone 10 of Simeiradski, 1906). Plotnick gives age as Lower Lochkovian. Following correlation chart of Gritsenko et al. (1999, PBDB ref. 6695), Upper Lochkovian seems more likely.

• formation-level stratigraphic resolution

Environment/lithology: marine; yellow marl

• "BA 1"
• "Fine-grained, yellow, marly limestone ('Korallen-mergel')"
