Phacops-Struveaspis Assemblage of the Eifelian (Barrandia, Cze) Assem. 18 (Devonian of Czech Republic)

Where: Barrandia, Czech Republic (50.1° N, 14.4° E: paleocoordinates 29.3° S, 38.7° E)

When: Acanthopyge Limestone Member (Chotec Formation), Eifelian (393.3 - 387.7 Ma)

• PJW: Acanthopyge Limestone according to Adrain & Chatterton (1994).

• member-level stratigraphic resolution

Environment/lithology: deep subtidal; shelly/skeletal, gray lime mudstone and mudstone

• "Benthic Assemblage 5"
• "grey to dark grey micrites and sparites show changes in grain size reflecting fluctations and pulses of higher energy, the assemblage is contained almost exclusively in micritic layers and mudstone intercalations"

Size classes: macrofossils, mesofossils
