Mutationella podolica Community, Chortkov and Ivane suites, Podolia (Devonian to of Ukraine)

Where: Ukraine (48.6° N, 25.9° E: paleocoordinates 46.6° S, 74.0° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Lochkovian to Lochkovian (419.2 - 407.6 Ma)

• Upper part of the Gedinnian-Seigenian from the Chortkov and Ivane Suites of the Tiverian horizon. See correlation chart (fig. 38.1).

Environment/lithology: marine; limestone and marl

• "Abundance of articulate sshells from detrital limestones, marls, and less commonly argillites, is consistent with average turbulence. Community commonly encountered within argillites having marl and limestone interbeds. Within Ivanevtsian horizon they are interbedded with red and grey aleurolites (=siltstones) yielding [ichthyofaunal list]. The more landward occurrences of the community yield almost 100% Mutationella, as well as some interbeds of large leperditicopes, which taken with the vertebrate data indicates transition from BA 2, for medium diversity community, through BA 1 for the monospecific unit, to the nonmarine or estuarine vertebrate community. The overlying red Dniestrovian series indicates the onset of long duration, stable, lagoonal-continental sedimentation."
• "detrital limestones, marls, and less commonly argillites"

Collection methods: Abundances given for brachiopods.
