Résumé : An association of eight taxons of marine algae is described from the anchimetamorphosed dolomites of Late Visean-Namurian A age. The algae confirm this determination of age based previously on conodonts. The flora is indicative of latest Visean Zone 16 to Early Serpukhovian Zone 17. The microfossils from the locality Furmanec are somewhat older, indicative of Late Visean (Zone 15 to 16?).
