Entelophyll.polymorphum-Nordastraea coronifera Comm.,W.Khatanzeya Fm.,Nov.Zemlya (Silurian of Russian Federation)

Also known as Reef 1686

Where: Russian Federation (71.0° N, 58.0° E: paleocoordinates 4.0° N, 1.5° W)

• coordinate estimated from map

• basin-level geographic resolution

When: West Khatanzeya Formation, Ludlow (427.4 - 423.0 Ma)

• Upper part of West Khatanzeya Formation.

• formation-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; wackestone and grainstone

• "...rugosan biostromes built chiefly of E. polymorphum and N. coronifera. As a rule the fossils occur in life position, partly as local disturbed assemblages accumulated on the carbonate sediments, in association with other rapidly varying life assemblages. This is a BA 3 moderate diversity community. All the fossils occur within the same patches in the mosaic. It should be noted here that the Didymothyris Community and ostracode communities occur mainly at the edges of rugosan biostromes and are also found as discrete patches between biostromes."
• "Occurs in finely laminated and lenticular-laminated wackestones and grainstones, with small rugosan biostromes..."
