| Abstract | Stratigraphically important conodonts relevant to the Givetian-Frasnian boundary are listed from one section in the Tafilalt area and from threein the Ma'der area. The conodont succession from the Middle Polygnathus varcus Subzone and extending into the Middle Polygnathus asymmetricus Zone is described. The corresponding goniatite sequence ranges from the last occurrence of Maenioceras terebratum into beds containing Manticoceras and Beloceras kayseri. The sedimentology of the beds sampled for conodonts at the Tafilalt section and at two of the Ma'der sections is discussed. The conodont Ancyrodella binodosa is fully described;other relevant taxa are briefly discussed. |
