Fig. 4. A in A new Metapolygnathus platform conodont species and its implications for Upper Carnian global correlations

Fig. 4. A schematic figure illustrating the evolution of Paragondolella noah (Hayashi, 1968) into its descendant species. The main evolutionary trends from P. noah to the last representative of the lineage, Metapolygnathus parvus Kozur, 1972, are observable: the gradual shortening of the platform, the forward shifting of the pit, the posterior lengthening of the keel termination and the development of nodes at the geniculation point. In M. parvus the nodes disappear for the extreme reduction of the platform. A, B. Metapolygnathus parvus Kozur, 1972 (sample NA37, Lower Norian, PMs). C, D.
