Trilobite assemblage 2 of the Lochkovian (Barrandian, Cze) Lochkovella-Lepidop (Devonian to of Czech Republic)

Where: Czech Republic (50.1° N, 14.5° E)

• Paleocoordinates: 16.9° S, 9.5° E (Wright 2013)

When: Monograptus hercynicus zone, Radotin Limestone Member (Lochkov Formation), Lochkovian to Lochkovian (419.2 - 382.7 Ma)

• "This assemblage of higher taxonomic diversity is contained within the shale-rich development of the upper Lochkov (Radotin Limestone)."

• member-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; argillaceous, calcareous wackestone

• "...changes of grain size, layers of coarser bioclastic material, graded bedding, sorting of organic remains and their concentration in thin layers point to less stable conditions and to pulses of higher energy. Assemblage 4 to 5 in Boucot's classification."
• "The lithology is characterized by dark bituminous platy biomicritic to finely biosparitic limestones with a variable ammount of intercalations of dark calcareous shale..."

Size class: macrofossils
