When discussing the relationship between lithology and faunal distribution patterns in a part of the Ooser Plattenkalk-sequence (Upper Devonian, Adorf-Stufe, Eifel Mountains, Germany), Böger (1966) quoted that neither the theory of Krebs 1962 (interchange of shallow and deeper marine environments) nor the interpretation of Meischner 1964 (intercalation of calcareous turbidites, “allodapic limestones”) is satisfactory.
