The highly diversified rugose coral fauna from the Lower Givetian Meerbüsch quarry in the Eifel Hills (Germany)

Twenty taxa of Lower Givetian rugose corals have been investigated in the Dreimühlen Formation from Meerbüsch quarry, Eifel Hills. The fauna consists mostly solitary coralla associated with some fasciculate specimens Disphyllum caespitosum (Goldfuss, 1826) and large massive colonies Argutastrea briceae (Rohart, 1988). genus Marennophyllum n. gen. is introduced Cystiphylloides marennense Coen-Aubert, 2019 as type species to include previously assigned Chapman, 1893. Three are new: wenningi sp., Grypophyllum schroederi sp. Macgeea mistiaeni n.sp. stratigraphic distribution material observed quarry compared that Middle Devonian Hills a whole, southern part Belgium, other countries Western Europe. Some such Acanthophyllum heterophyllum (Milne-Edwards & Haime, 1851), A. vermiculare 1826), convolutum (Wedekind, 1925), Stringophyllum acanthicum (Frech, 1885) Aristophyllum luetti 1997 also present at northern margin Gondwana (Ma’der Morocco, Zemmour Mauritania, Alborz Mountains Iran). occurrence Heliophyllum cf. cribellum Oliver Sorauf, 2002 suggests an Eastern North American influence.
