Joachymia-Cardiolinka-Pygolifa Community in the Prague Basin (Silurian of Czech Republic)

Where: Czech Republic (49.9° N, 14.2° E: paleocoordinates 49.0° S, 55.3° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Monograptus transgrediens zone, Pridoli (423.0 - 419.2 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: marine; gray lime mudstone and shelly/skeletal, gray limestone

• Life modes of bivalves include infaunal, epibyssate, semi-infaunal, and reclining. Ceph. shells mostly current oriented SSW-NNE. Pop'n densities high. Environment shallow subtidal, influenced by relatively high current activity, but protected from strong wave action. [quoted or paraphrased from author]
• "Disarticulated shells are preserved in gray, biomicritic limestone to fine-grained biodetrital limestone."

Collection methods: Bivalves (table 16.18) definitely from type locality. Text suggests that other material is also found there. Author gives abundance and life mode for bivalves.
