| Abstract |
Plicathyridine brachiopods (Athyridida) from the early–middle Frasnian of southern Belgium and northern France (Dinant Synclinorium) are systematically described for the first time. They include two species: Anathyris (Anathyris) calestiennensis nov. sp., and A. (A.) sp. indet. 1. They are uncommon in the mainly shally La Prée (Nismes Formation) and Ermitage (Moulin Liénaux Formation) members and are absent from the mixed argillaceous–carbonate late Frasnian succession in this area contrary to what is observed in Russia, notably in the East-European Platform and Siberia. In the Middle East, two species of Anathyris are recognized on the basis of a limited material from the Dascht-e-Nawar area in Afghanistan (A. (A.) sp. indet. 2) and the Kuh-e Kaftar mountains in Central Iran (A. (A.) sp. indet. 3). Anathyris (A.) calestiennensis nov. sp. is sometimes encrusted by epizoans (tabulate and rugose corals, and bryozoans) and rarely displays single, small circular drill holes. The past and current epizoan–brachiopod interactions are also discussed (Anathyris vs. Lingula, respectively). |
