Conodont biofacies of middle and upper devonian limestones, Brilon area, West Germany
From thirty-three Devonian sections in the eastern Rhenish Schiefergebirge, West Germany, large numbers of conodonts were recovered in the vicinity of the Brilon bioherm. Statistical investigation allows the reconstruction of conodont distribution in the restricted area of the fore-reef through time. During reef growth conodont distribution is well recognized. The influence of sedimentation and allochthonous factors, as well as the habitats of different conodont genera often can be separated. After death of the reef in the late Frasnian (Ancyrognathus triangularis zone) sedimentation gradually changed to uniform pelites. The distribution pattern does not change much throughout the 10 zones investigated.
