Atrypoidea prunum Community, Podolia (Silurian of Ukraine)

Where: Ukraine (48.5° N, 26.6° E: paleocoordinates 18.5° S, 7.5° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Pridoli (423.0 - 419.2 Ma)

• Upper part of Tsviklevtsy suite and Ryhkta suite of Malinovtsy series (Ulichian superhorizon).

Environment/lithology: marine; marl and argillaceous limestone

• "[Occurrence and lithology] suggest that the environment was in relatively quiet water.

• Coexistence of D. didyma and Atrypoidea prunum Communities indicates moderate level of regular environmental change, but a relatively similar BA position [D. d. shallower, A. p. finer, muddier]."

• "A. prunum itself commonly occurs in Podolia as big clusters of articulated, large and small specimens, buried in massive marl. There are rare occurrences in argillaceous, detrital limestone as disarticulated shells." [But it is also stated that the other brachiopods "occur rarely in these nests of shells."]

Collection methods: Abundances given for brachiopods.
