The uppermost parts of the Lower Drimos Limestones from the section at Karpenission contain a rich conodont assemblage corresponding to the middle parts of the Sevatian Epigondolella bidentata R. Z. It is dominated by the species Misikella postlzernsteini Kozur & Mock and Paragondolella steinbergensis Mosher, and contains the new conodont species Epigondolella postspatulata Budurov & Mavridis. A rich radiolarian complex has been found too; it contains specific Upper Triassic taxa belonging to Spumellaria and Nassellaria including representatives of superfamily Archecyrtoidea. The foraminiferal assemblage is characterized also by taxa typical of the Upper Triassic.
Red cherts from the base of the overlying cherty interval contain a radiolarian complex of Late Norian – Rhaetian age.
