Abstract
    Both conodonts and megafaunal associations have been examined from two Frasnian sections at Nismes and Mariembourg (Dinant Synclinorium, Belgium). The recognition of the Late hassi?, the jamieae, and the Early rhenana Conodont Zones (= Ancyrognathus triangularis (Ziegler, 1962) and Lower Palmatolepis gigas Zones (Ziegler, 1971)) makes it possible to situate both sections in the middle and upper part of the Frasnian. From the base towards the top of the Nismes section there is a deepening of the environment. This can be documented by the conodont biofacies, the megafaunal associations and some lithological characteristics.
