首次系统研究浙江黄芝山剖面二叠-三叠系界线附近的牙形类化石,共鉴定2属16种,并据此识别出5个牙形类化石带,从下至上依次为:Clarkina changxingensis changxingensis带,C.parasubcarinata带,C.chan-gxingensis yini-C.meishanensis zhangi带,C.meishanensis meishanensis带,Hindeodus parvus带。Hindeodus changxingensis,H.eurypyge,H.parvus分别在第15层、第18层底部、第18层中部依次出现,为确定该剖面二叠-三叠系界线在18-3层之底提供了依据。作者还讨论黄芝山剖面二叠-三叠系界线附近的牙形类序列与浙江煤山、伊朗剖面二叠-三叠系界线层牙形类序列的对比。
For the first time, the study of teratoid fossils near the Permian-Triassic boundary in Huangzhi Mountain, Zhejiang Province, systematically identified 16 genera and 2 genera, and identified 5 albino fossils from bottom to top as follows: Clarkina changxingensis changxingensis C. parrasubcarinata, C.chan-gxingensis yini-C.meishanensis zhangi, C.meishanensis meishanensis, Hindeodus parvus. Hindeodus changxingensis, H.eurypyge and H. parvus appear at the bottom of the 15th, 18th and the middle of the 18th, respectively, providing the basis for determining the bottom of the 18-3 layer in the Permian-Triassic boundary of this section. The author also discusses the comparison of the conodonts between the Permian-Triassic boundary in the Huangzhi Mountain section and the Permian-Triassic boundary layer in the Meishan and Iranian sections of Zhejiang Province.
