Acastella heberti Community, Khudykovtsy suite, Podolia (Devonian of Ukraine)

Where: Ukraine (48.6° N, 26.1° E: paleocoordinates 18.6° S, 10.1° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Khudykovtsy Suite Formation, Lochkovian (419.2 - 410.8 Ma)

• Khudykovtsy "suite" of the Borshchovian "horizon". See fig. 38.1 for correlation chart.

• formation-level stratigraphic resolution

Environment/lithology: marine; black, argillaceous limestone and gray, calcareous mudstone

• "This community occurs in a deep shelf position, and is assigned to BA 4. Brachiopods are abundant, adn their commonly articulated condition suggests relatively quiet water."
