| Description | This paper deals in detail with the conodont sequences and the evolution of Clarkin lineage and Hindeodus--Isarcicella lineage on the buis of the Upper Permian -Lower Triassic Conodonta from the Mcishan section, Changeing. Zhejiang Province, South China, Which is proposed as a Candidate of the Global Stratotype Section and Point of the Permian-Triassic boundary. Three Upper Permian-Lower Triassic Conodont Zones arc defined in ascending order, as follows. Clarkina changxingensis Zone, Hindeodus Parvus Zone, and Isarcicella isarcica Zone. The Clarkina changxingensis Zone is subdivided into three faunas, the Clarkina changxingensis-C. dleflecta-C. subcarinata fauna, the Hindeodus latidentatus-Clarkina meishanensis fauna and the Hindeodus typicalis fauna. It is very important that the conodont sequences established in the Permian-Triassic boundary strata at the Meishan section make a complete zonation and correlation over the world. This significantly helps the precise definition of the Permian-Triassic boundary at the Meishan section. The Clarkina stock at section D of Meisban, Changxing, appeared only in the Upper Permian and represented the descendant of the Eurasian stock. It is mainly Composed of Clarkina orientalis (Sarakov and Koroleva), C. subcarinata (Sweet), C. wangi (Zhang), C. changxingensis (Wang and Wang), C. deflecta (Wang and Wang), C. carinata (Clark) and C. dicerocarinata (Wang and Wang). Clarkina oriental is is the ancestor of C. subcarinata. C. subarinata diverged into three branches, i.e., C. Changxingensis, C. deflecta and C. carinata. C. deflecta further developed into C. dicerocarinata. The evolution of Clarkina wangi is unsettled. The evolution of Hindeodus-Isarcilella stock at the Mcishan section, Changxing, is Hindeodus latidentatus-H. parvus-Isarcicella turgida-I. isarcica. Book Name: Stratigraphy |
