Temnophyllum delmeri n. sp., and T. ramosum n. sp. are described in detail and come from the Upper Givetian of Belgium. On the south side of the Dinant Synclinorium, T. delmeri is associated with Sunophyllum beichuanense HE, 1978 and Wapitiphyllum laxum (GÜRICH, 1896), at the top of the Mont d'Haurs Formation. It is also present in the Flohimont Member, the lower subdivision of the Fromelennes Formation. At the base of the overlying Moulin Boreux Member, there is a level of limestones rich in stringocephalids, diverse groups of tabulate corals and in rugose corals represented by W. laxum , Temnophyllum ramosum , T. delmeri and locally Sunophyllum beichuanense . Nearly all these fossils disappear higher in the Moulin Boreux Member. The same situation has been observed in the Philippeville Massif on the north side of the Dinant Synclinorium and in the Vesdre Massif. As the base of the Flohimont Member lies at the top of the Lower Polygnathus varcus Zone and as the major part of this lithostratigraphic unit belongs to the P. ansatus Zone corresponding to the Middle P. varcus Zone, it is quite possible that the Taghanic Event occurs in Belgium just above the level of limestones with the last stringocephalids.
