Aulacopleura konincki Community, Prague Basin (Silurian of Czech Republic)

Where: Czech Republic (50.0° N, 17.8° E: paleocoordinates 52.6° S, 62.0° E)

• coordinate based on political unit

• local area-level geographic resolution

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

• formation-level stratigraphic resolution

Environment/lithology: marine; calcareous shale

• "The rather deep water A. konincki Comm. is poor in sessile benthos...[Chlupac assigned to BA 4-5.] Gradational realtions with the black, graptolitic shale facies suggest a BA 5 position...The rarity of sessile benthos is consistent with a lower oxygen level or possible a very soft substrate unsuited to most fixed organisms. The presence of articulated trilobites and sponges suggests a quiet water environment..."
• "The dark, commonly calcareous shales have yielded [faunal list].."

Collection methods: Some trilobites and other elements added from Chlupac (1987), ref. 6191.
