Decouverte d'un brachiopode inarticulé Acrothele cf. Bergeroni Walcott, dans le Revinien inferieur de trois-ponts, Cambrien du Massif de Stavelot, Belgique

The Revinian (Cambrian) of the Ardenne, from which no macrofossils have hitherto been recorded, has yielded two inarticulate brachiopods determined here as Acrothele cf. bergeroni WALCOTT. The specimens were found south of Trois-Ponts in the Stavelot Massif, at a horizon referred to division Rn1a. The stratigraphic age suggested by the brachiopods is compared with that indicated by acritarchs : a Middle Cambrian age seems probable.
