Niorhynx Comm. at Reporyje/Butovice, Motol Fmn., Prague Basin (Silurian of Czech Republic)

Where: Czech Republic (50.0° N, 14.3° E: paleocoordinates 54.9° S, 60.1° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Motol Formation, Wenlock (433.4 - 427.4 Ma)

• No further detail given, but Boucek (1937) would be worth consulting.

• formation-level stratigraphic resolution

Environment/lithology: marine; gray limestone and black shale

• General for this Community: "The relatively low diversity ... and its relative depth position might be explained by a quiet water, lower oxygen environment...In the Svaty Jan area the [limestones containing this community intercalate with laminated Lsts containing Miraspis-Mezounia Comm.]"
• General for this community: "In spite of the pronounced slump features in the bituminous limestones...the shelly fauna is neither crushed nor disarticulated. Relations with other communities suggest BA 4...The Community occurs in limestone lenses and intercalations within the graptolitic shale sequence...A BA 4 position is suggested..."

•For this local occurrence: includes mention of "...grey bioclastic limestone just overlying the graptolitic shales..."
