PBDB Collection

Didymothyris didyma Community, Podolia (Silurian to of Ukraine)

Where: Ukraine (48.5° N, 26.6° E: paleocoordinates 19.9° S, 7.5° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Ludlow to Ludlow (427.4 - 419.2 Ma)

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

Environment/lithology: marine; argillaceous limestone and marl

• "Presence of high percentage of articulated specimens consistent with quiet water, although moderate diversity and rock types (including lack of lamination) speak for a reasonable level of current activity necessary for normal oxygen levels. Percent of disarticulated shells consistent with this conclusion. Coexistence of D. d. and Atrypoidea prunum Communities indicates moderate level of regular environmental change, but a relatively similar BA position [D. d. shallower, A. p. finer, muddier]."

• "Occurs in argillaceous, nodular limestone and less commonly in massive marls."

Collection methods: Abundances given for brachiopods.
