Koneprusites-Cyphaspides Assemblage of the Eifelian (Barrandian, Cze) Assem. 17 (Devonian of Czech Republic)

Where: Czech Republic (49.9° N, 14.1° E: paleocoordinates 29.6° S, 38.5° E)

When: Polygnathus costatus partitus, Tortodus kockelianus australis, Nowakia sulcata, Nowakia pumilio conodont zone, Acanthopyge Limestone Member (Chotec Limestone Formation), Eifelian (393.3 - 387.7 Ma)

• PJW: This should be Acanthopyge Limestone.

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal; shelly/skeletal, gray grainstone

• "Assemblage may be interpreted as subtidal of medium depth (probably Assemblage 4 of Boucot)the transport in a deeper zone should be considered."
• Layered accumulations of fossils occur in predominantly grey sparites; they alternate with dark grey micrites and calcareous mudstone with a different trilobite assemblage- the Phacops-Struveaspis Assemblage.

Size class: macrofossils
