The “Rocher de Falize” in Durbuy, a nice example of an anticline in the Upper Devonian.
Upper Devonian of the Ardennes
Late Devonian rocks in the Ardennes outcrop mainly
in the synclinoria of Dinant and Namur, and in the Vesdre Nappe and the Theux Window
(Fenêtre de Theux). Mud mounds in the south are well documented and of international
interest. They are alternated by shaly sediments and all these environments are reflected
in the trilobite assemblages that they yield. Scutelluids, for instance, are commonly
associated with bioherms whereas acastids preferred the shales and limestones.
