Encrinurus punctatus Community, Demshin subsuite, Podolia (Silurian of Ukraine)

Where: Ukraine (48.7° N, 26.8° E: paleocoordinates 24.7° S, 7.3° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Demshin Subsuite Formation, Wenlock (433.4 - 427.4 Ma)

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

• formation-level stratigraphic resolution

Environment/lithology: marine; marl and argillaceous limestone

• "...on western slope of the Ukrainian Shield. The disarticulated condition of the trilobites indicates a normal level of turbulence, although the high percentage of articulated brachiopods indicates that this was not a rough water environment. BA 3."
• "marls and argillaceous limestones"

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.
