[more ▼] An additional level of Frasnian mounds has been recognized in the La Boverie quarry at Rochefort and in four boreholes drilled in the Nord quarry at Frasnes, on the south side of the Dinant Synclinorium. It occurs between the Arche and Lion Members belonging respectively to the Moulin Liénaux and Grands Breux Formations, in the middle part of the stage. The new name of La Boverie Member is introduced at the top of the Moulin Liénaux Formation, for the deposits lying between the Arche and Bieumont Members; the latter is the basement of the Lion mound. The same succession has been observed in the sections of Moulin Bayot close to Vodelée, in the southeastern part of the Philippeville Anticlinorium. The La Boverie Member starts with rather deep bioclastic sediments, after the collapse of the carbonate factory at the top of the Arche mound. In the upper part of the lithostratigraphic unit, there is a thin buildup characterized by relatively shallow facies. The solitary rugose corals Macgeea boveriensis n. sp., M. socialis SOSHKINA, 1939 and Sinodisphyllum posterum (IVANIA, 1965) collected in the lower part of the La Boverie Member are described in detail whereas the revision of S. kielcense (ROZKOWSKA, 1979) occurring in the Bieumont Member is also provided.

[more ▼] The fossils which De Koninck described and illustrated as members of the molluscan Class Scaphopoda have been reexamined. For the first time, photographs of these specimens are presented. Scaphopod shells show only a limited number of morphologic features and for most of these species, the details are lacking which would indicate that the fossils belong undoubtedly in the Scaphopoda. The study suggests that most of the named species may not be Scaphopoda; these species are assigned to informal groupings, ranging from Incertae sedis, through "worm tubes" to "probably Scaphopoda". Only one specimen may be identified without question as a member of the scaphopods.

[more ▼] The brachiopods sampled from the Trois-Fontaines Formation in the Marenne quarry are mainly represented by two species: Spinatrypina (Spinatrypina) fontis n. sp. and Eifyris socia n. sp. Orthid, rhynchonellid, spiriferid and terebratulid brachiopods are also present but much rarer. Among them a new species, Bornhardtina equitis n. sp., is described, the others being only briefly discussed.

[more ▼] Cyrtina rigauxi Maillieux, 1909 is transferred to the genus Acutatheca Stainbrook, 1945 thus mentioned for the first time in the Frasnian of the Dinant Synclinorium and Roly "Massif" (Neuville Formation, Lower Palmatolepis rhenana Zone). Maillieux (1940, 1941) included Acutatheca rigauxi in Cyrtina demarlei Bouchard (nomen nudum) and C. heteroclita (Defrance, 1824). The specimens identified as Martiniopsis (Elivella) rigauxi by Maillieux (1940, 1941) [= Echinocoelia rigauxi sensu Vandercammen (1956)] do not belong to C. rigauxi Maillieux, 1909. They are redescribed as Dionacoelia secessus n. gen., n. sp., a species occurring with certainty in the Ermitage Member of the Moulin Lienaux Formation (Palmatolepis punctata Zone).

[more ▼] 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.
