Givetian rugose corals of the Schlade Event Bed (Bergisch Gladbach, Germany)

In the middle-upper Givetian strata of the Bergisches Land, the Schlade Event Bed is an unusual black mudstone horizon that fouled a sea bottom community made of corals and stromatoporoids. The coral assemblage, here taxonomically described, is dominated by two taxa: Temnophyllum latum and Acanthophyllum vermiculare. The position of the corals in the sediment and ecological adaptations tend to show that they lived in turbid water, most probably during the deposition of the mud but were not reworked in it as previously suggested.
