| Abstract |
The genus Biernatella (Brachiopoda; Athyridida), characterized by the presence of a diplospiralium, is definitely recognized for the first time in the late Frasnian (Lower - Upper Palmatolepis rhenana Zones) of the southern flank of the Dinant Synclinorium and of the Philippeville Anticlinorium (southern Belgium). A new species (B. abunda n. sp.) from the Neuville Formation (Dinant Synclinorium) is described. In the Philippeville Anticlinorium, B. abunda n. sp. occurs in the Neuville Formation and probably at the base of the Les Valisettes Formation but specifically unidentified specimens of Biernatella have also been collected near the top of this last formation. |
