| Abstract: | In the Reun ar C'Hrank section (Rade de Brest), the Conodonts from just above the base of the Beg an Arreun Formation of the Troaon Group in the Armorican Massif indicate the Polygnathus laticostatus Zone, which belongs to the highest Zlichvian and the base of the Dalejan. Species of Icriodus from the same beds indicate a correlation with the lower and middle part of the Hierges Formation, which represents the Upper Emsian in the Ardennes. Conodonts from Le Fret Formation are tentatively assigned an Upper Emsian/Dalejan age. |
