The Daleje Shale of Zlichovian age, Barrandian (CZE) (Devonian of Czech Republic)

Where: Czech Republic (50.0° N, 14.4° E: paleocoordinates 38.7° S, 48.8° E)

When: Nowakia elegans zone, Daleje Shale Member, Early/Lower Emsian (409.1 - 402.5 Ma)

• the lowermost part of the Daleje Shale corresponds to the Nowakia elegans zone and is thus topmost Zlichovian in age, while the succeeding beds are Dalejan in age.

Environment/lithology: deep subtidal; bioturbated, concretionary, gray, green, red, calcareous mudstone and gray lime mudstone

• "low-energy quiet conditions in the deeper subtidal zone, most likely Benthic Assemblage 4 to 5 of Boucot."
• "Grey, green, red Chondrites-bearing calcareous mudstones with concretions of grey micritc limestones. A rhymic alternation of darker (grey-green) and lighter (olive-green) shales commonly occurs; the proportion of limestone concretions and intercalations increases upwards (a transition into the Trebotov Limestones)."

Size class: macrofossils

Collection methods: This collection gives the taxa listed for the Daleje Shale of Zlichovian age. The collection #12144 gives the taxa listed for the Daleje Shale of Dalejan stage.
