Abstract
Mockina slovakensis, thought to have evolved from Epigondolella praeslovakensis, is an important species of the Norian (Upper Triassic), generally considered as the representative of the uppermost Alaunian to upper Sevatian in the Tethys. The previous description of M. slovakensis was incomplete, thus has led to some misidentifications. We thus update the description of M. slovakensis and discuss its comparisons and occurrence based on the new conodont investigations in Dolomia di Forni and the data from previous literatures. The conodont assemblage in the succession of Dolomia di Forni is dominated by M. slovakensis, along with rare M. postera and E. praeslovakensis. We described two morphotypes of M. slovakensis (morphotypes A and B), on the basis of shape of the lateral profile. These two morphotypes can also be observed in the E. praeslovakensis. Moreover, M. slovakensis is usually documented as almost monospecific conodont association in intraplatform basins, thus its paleogeographic implications are also discussed.
