New species of Frechastraea Scrutton, 1968 at the base of the Late Frasnian in Belgium

Frechastraea coeni n. sp. is widely distributed at the base of the Late Frasnian from the Philippeville Massif, the north side of the Dinant Synclinorium, the south side of the Namur Synclinorium and the Vesdre Massif. It occurs within the Early Palmatolepis rhenana conodont Zone and is locally associated with F. glabra n. sp. and F. phillipsastraeiformis (Moenke, 1954). However, F. phillipsastraeiformis , which is also described in this paper, may be already present at the top of the Middle Frasnian from the Philippeville Massif and the south side of the Dinant Synclinorium.
