Proetus cf. obconicus Community, Konovka Suite, Podolia (Silurian of Ukraine)

Where: Ukraine (48.5° N, 26.7° E: paleocoordinates 22.7° S, 7.4° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Konovka Suite Formation, Gorstian (427.4 - 425.6 Ma)

• Konovka "suite" of the Malinovtsy "series". See correlation chart, fig. 38.1.

• formation-level stratigraphic resolution

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

• "interpreted as a shallow bar, closed shelf, outer part of a lagoon. Disarticulated nature of trilobites [and brachiopods] indicates normal turbulence. Brachiopods are dominant in the marls, whereas stromatoporoids and corals dominate in the limestones. A BA 2, photic zone unit [biota also includes algae]."
• "Occurs in calcareous shale and biohermal, coral-algal limestone, plus polydetrital, slightly argillaceous limestone."

Collection methods: Counts are given for trilobites.
