The results of micropaleontological studies, especially of conodonts, across the Permian-Triassic (P-T) boundary interval in the Bálvány-North, Bálvány-East and Gerennavár sections of the Bükk Mountains (NE Hungary) are presented. Conodont zones for the boundary interval have been identified on the basis of biostratigraphic data for conodont taxa (Hindeodus parvus, H. praeparvus, Hindeodus sp., Isarcicella cf. prisca, Hindeodus /Isarcicella sp.) and the FOD of H. parvus. The praeparvus Zone possibly the Late praeparvus Zone (uppermost part of Changhsingian, Late Permian) in the Nagyvisnyó Limestone, inclusive of the 'Boundary Shale Bed', and the parvus Zone (earliest Induan, Early Triassic) in the Gerennavár Limestone are discriminated.
