Hlinik, Svaty Jan pod Skalou (Silurian of Czech Republic)

Also known as Strophoprion-Eoplectodonta Community, Prague Basin

Where: Czech Republic (50.0° N, 14.1° E: paleocoordinates 54.4° S, 59.4° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Cyrtograptus lundgreni graptolite zone, Motol Formation, Homerian (430.5 - 427.4 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; volcaniclastic, calcareous shale and volcaniclastic, gray, green limestone

• "...confined to quiet water, subtidal, soft bottom environment of redeposited basaltic tuffs on top of the volcanoclastic elevation, in the euphotic zone with fossil algae....We assign it a BA 3-4 position [explanation follows, with abundant comparison to other communities]."
• "...a sequence of tuffaceous and calcareous shales interbedded with tuffaceous limestones containing abundant benthos. Some shale intercalations yield dendroids and graptolites of the C. lundgreni zone...gray-green tuffaceous limestones [at Barrande's locality]..."

Size class: macrofossils

Collection methods: Authors give relative abundance data (very rare, more frequent, frequent) for brachiopods.
