Acanthophyllum heterophyllum (MILNE-EDWARDS & HAIME, 1851), A. vermiculare (GOLDFUSS, 1826) and Aristophyllum luetti n. sp. are described in detail and have been mainly collected at Pondrôme, Wellin and Resteigne where important facies variations appear near the Eifelian-Givetian boundary. Acanthophyllum heterophyllum occasionally occurs at the top of the Jemelle Formation, in the Hanonet and X Formations and also at the base of the Trois-Fontaines Formation. A. vermiculare is mostly characteristic of the Hanonet Formation, but is still present at the base of the Trois-Fontaines Formation. Aristophyllum luetti n. sp. is usually restricted to the upper part of the Hanonet Formation. Thin sections of the holotype of Acanthophyllum heterophyllum, type species of the genus Acanthophyllum DYBOWSKI, 1873, are figured for the first time.
