Brachiopods from the White Chalk of Meudon (Upper Campanian) of the dˈOrbigny collection (NMHN, Paris)

Brachiopods from the White Chalk of Meudon (Upper Campanian), listed in the catalogue of dˈOrbigny collection, are presented following the revised classification. This is not without difficulty, due to the few specimens found and/or to the heterogeneity of sets listed under the same number and labelled with the same name. The Brachiopod fauna in the Belemnitella mucronata Zone is well represented, considering the Invertebrate fauna as a whole. Two representatives of Craniiformea and about ten species of Rhynchonelliformea, from several superfamilies shared by two orders, are critically described, considering the recent observations and the last works after dˈOrbigny.
