Where: Barrandia, Czech Republic (49.5° N, 14.3° E: paleocoordinates 34.4° S, 46.0° E)
When: Nowakia elegans, Nowakia cancellata zone, Daleje Shale Member, Zlichovian to Zlichovian (409.1 - 393.3 Ma)

• "Boucot's Benthic Assemblage 4 to 5...depth not substantially different frm Phacops-Struveaspis Assemblage, the main difference concerned the influx of clayey material."
• "grey, green,and overlying red calcareous mudstones with concretions of micrites"
