Calymene restevensis Community, Restevo subsuite, Podolia (Silurian to of Ukraine)

Where: Ukraine (48.6° N, 26.9° E: paleocoordinates 28.3° S, 7.0° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Restevo Subsuite Formation, Llandovery to Llandovery (443.4 - 427.4 Ma)

• Restevo subsuite of Yaruga series (Kitaigorodian superhorizon or "stage"). Fig. 38.1 gives correlation chart.

• formation-level stratigraphic resolution

Environment/lithology: marine; gray claystone and marl

• "interpreted as slope and deep shelf. BA 4 likely as indicated by fauna. Disarticulation of trilobites indicates low level of turbulence, because numerous brachiopods still articulated."
• "dark gray argillite and marl interlayered with muddy, detrital, organogenic limestone"

Collection methods: Counts are given for trilobites. It seems implicit that all elements are known from type locality, even though the community is more widely distributed.
