| Abstract |
Frechastraea pentagona (Goldfuss, 1826), type species of Frechastraea Scrutton, 1968, F. minima (Rozkowska, 1953), F. micrommata (Roemer, 1852), F. kaisini (Tsien, 1978), F. cf. tungkanlingensis (Yoh, 1937), F. crassiseptata (Tsien, 1978) and F. limitata (Milne-Edwards & Haime, 1851) occur mainly in the Upper Palmatolepis rhenana conodont Zone. Their stratigraphic distribution is discussed in the Upper Frasnian of Belgium and compared with other areas of Western and Eastern Europe. The Belgian material previously identified as Frechastraea micrastraea (Penecke, 1904) is now assigned to F. crassiseptata. The Champ Broquet Formation is proposed herein to include the Neuville and Les Valisettes Members which were formerly considered as two different formations. The red marble lenses of the Petit-Mont Member are developed at different levels of the Champ Broquet Formation, in the Dinant Synclinorium. |
