Newly introduced steinachensis Zone is characterized by the first occurrence of L. steinachensis eta morph. In the Lo/Pg GSSP at Velká Chuchle, Barrandian, it is in the bed No. 10. Considering also the other sections in the Barrandian area, this zone is the most effective local marker for the base of the Pragian. The abundance of latericriodus steinachensis elements is much higher than those of Eognathodus sulcatus and the present and past determinations of L. steinachensis are also more reliable than those of E. sulcatus. Revision of the taxonomy and distribution ranges of conodonts in Lo/Pg GSSP Velká Chuchle allow to correlate this point with sections in Morocco and Spanish Paleozoic terranes.
