On the basis of existing conodont data, the authors have studied the Late Permian‐Early Triassic cohodonts of different farms and biofacies in detail Five conodont biofacies are recognised, from shallow to deep water: 1. Hindeodus conodont biofacies 2. Pachycladina‐Parachi rognathus conodont biofacies, 3. Gondolella‐Hindeodus Conodont biofacies, 4. Gondolella ‐ Neospathodus conodont biofacies, and 5. Xaniognathus cohodont biofacies. Considering the temporal and spatial changes of these conodont biofacies, 3 conodont bioprovinces have been divided. In light of the biofacies changes of each bioprovince, the authors also discuss, in this paper, the regularity of transgression‐regression cycles of eastern Tethys and their possible relation to the mass biotic alternation.
