Evolution and zonation of Permian and Triassic conodonts are newly delineated with acknowledgment of conodont provincialism. Ten evolutionary stages and eleven evolutionary events are recognized for the Permian and Triassic. Among them, four stages and four events are Permian and six stages and seven events are Triassic. Two patterns of evolution, namely Substitute Pattern and Extinction-Survival-Recovery Pattern, are suggested for the conodont evolution crises in the Permian and Triassic. Two types of Permian conodont zonations are summarized in term of warm water and cool water nature. Based on the materials from South China, a warm water Permian conodont zonation is established and its mutual correlation with that for cool water provinces is made. Twenty six Triassic conodont zones are proposed for the purpose of global correlation. In ascending order, they are: Hindeodus parvus zone, Isarcicella isarcica zone, Clarkina carinata zone, Neospathodus kummeli zone, Neospathodus dieneri zone, Neospathodus cristagali zone, Neospathodus pakistanensis zone, Neospathodus waageni zone, Neogondolella milleri zone, Neospathodus triangularis zone, Neospathodus homeri zone, Neogondolella jubata zone, Chiosella timorensis zone, Neogondolella regale zone, Neospathodus kockeli zone, Neogondolella constricta zone, Neogondolella mombergensis zone, Budurovignathus mungoensis zone, Paragondolella polythiformis zone, Metapolygnathus nodosus Zone; Epigondolella abneptis zone; Epigondolella multidentata zone, Epigondolella postera zone, Epigondolella bidentata zone, Misikella hernsteini zone and Misikella posthernsteini zone.
