Radotin Limestone of the Lochkov Fm, Lockovian (CZE) (Devonian of Czech Republic)

Where: Prague, Czech Republic (49.5° N, 14.3° E: paleocoordinates 45.3° S, 52.9° E)

When: Monograptus uniformis, Monograptus praehercynicus, Monograptus hercynicus, Nowakia bohemica, Paranowakia intermedia, Icriodus woschmidti woschmidti, Pedavis pesavis zone, Radotin Limestone Member (Lochkov Formation), Lochkovian (419.2 - 410.8 Ma)

Environment/lithology: deep subtidal; graded, shelly/skeletal, calcareous, cherty/siliceous lime mudstone

• "deeper subtidal environment of medium energy, Benthic Assemblages 4 to 5 of Boucot."
• "dark bituminous platy micritic to sparitic impure limestones with a variable amount of dark calcerous shale intercalations; cherts are common in some places...graded bedding and laminations are common, the limits between limestone and shales are obviously unsharp and marked by vertical transitions...This unit interfingers laterally with the Kotys limestone."

Size class: macrofossils

Collection methods: Author states that spores are common, but does not elaborate. Author states "land plants belong to the Cooksonia flora developing from the upper Silurian."
