Selected vertebrates interbedded with M. podolica Comm., Ivane suite, 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: Ivane Suite Formation, Lochkovian to Lochkovian (419.2 - 407.6 Ma)

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

• formation-level stratigraphic resolution

Environment/lithology: marine; gray siltstone

• [From description of Mutationella podolica Community]: "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."
• "red and grey aleurolites (=siltstones)"
