Mitkov Beds at S-D boundary sections in Dniestr Valley (Devonian of Ukraine)

Where: Ukraine (49.0° N, 25.8° E: paleocoordinates 18.5° S, 9.7° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Mitkov Beds Formation, Lochkovian (419.2 - 410.8 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; calcareous mudstone and shelly/skeletal, argillaceous limestone

• Several rock types mentioned: "...mudstones and rare bands of argillaceous limestone (19.4 m)...alternating mudstones, biogenic limestones, and marls. The limestones often form a coquina (63.5 m)...poorly calcareous mudstones with rare biogenic coquina limestones (25.85 m)."

Collection methods: Several outcrops combined.
