贵州罗甸纳水剖面是研究宾夕法尼亚亚系牙形刺和各阶界线的良好剖面.经详细研究,从石炭系中间界线至石炭-二叠系界线,一个新的牙形刺序列为Gnathodus bilineatus bollandensis(密西西比亚系顶部),Declinog-nathodus noduliferus, Idiognathoides sulcatus sulcatus, Id. sinuatus, Id. corrugatus-Id. pacificus, Neognatho-dus symmetricus, Idiognathodus primulus-Neognathodus symmetricus, Idiognathodus primulus-Neognathodus bassleri, Idiognathoides sulcatus parva, Streptognathodus expansus, Idiognathoides ouachitensis, Diplognatho-dus coloradoensis, Di. ellesmerensis, Gondolella donbassica-Go, clarki, Idiognathodus podolskensis, Swadelina subexcelsa, Sw. makhlina-Sw, nodocarinata, Idiognathodus sagittalis, Streptognathodus cancellosus, St. graci-lis, St. guizhouensis, Idiognathodus simulator, I. nashuiensis, Streptognathodus firmus, St. tenuialveus, St. wabaunsensis和St. isolatus(二叠系)等带.Declinognathodus noduliferus和Streptognathodus isolatus的首次现分别代表宾夕法尼亚亚系和二叠系之底;Diplognathodus ellesmerensis, Idiognathodus sagittalis和J. simula-tor的首现则可分别代表莫斯科阶(Moscovian),卡西莫夫阶(Kasimovian)和格舍尔阶(Gzhelian)之底界.作者较为详细讨论了巴什基尔阶与莫斯科阶以及卡西莫夫阶与格舍尔阶之界线,并认为以Diplognathodus ellesmerensis的首现作为巴什基尔阶(Bashkirian)与莫斯科阶之界线足目前最合适的标志.Diplognathodus ellesmerensis是一易于识别、分布广泛及层位稳定的牙形刺种,其产出又十分接近巴什基尔阶与莫斯科阶的传统界线,因此是划分此界线的良好标志.作者拟推荐纳水剖面为莫斯科阶底界之候选层型剖面,这一界线详细的工作正在大量采样分析和深入研究中,成果将在以后陆续发表.
貴州囉甸納水剖麵是研究賓夕法尼亞亞繫牙形刺和各階界線的良好剖麵.經詳細研究,從石炭繫中間界線至石炭-二疊繫界線,一箇新的牙形刺序列為Gnathodus bilineatus bollandensis(密西西比亞繫頂部),Declinog-nathodus noduliferus, Idiognathoides sulcatus sulcatus, Id. sinuatus, Id. corrugatus-Id. pacificus, Neognatho-dus symmetricus, Idiognathodus primulus-Neognathodus symmetricus, Idiognathodus primulus-Neognathodus bassleri, Idiognathoides sulcatus parva, Streptognathodus expansus, Idiognathoides ouachitensis, Diplognatho-dus coloradoensis, Di. ellesmerensis, Gondolella donbassica-Go, clarki, Idiognathodus podolskensis, Swadelina subexcelsa, Sw. makhlina-Sw, nodocarinata, Idiognathodus sagittalis, Streptognathodus cancellosus, St. graci-lis, St. guizhouensis, Idiognathodus simulator, I. nashuiensis, Streptognathodus firmus, St. tenuialveus, St. wabaunsensis和St. isolatus(二疊繫)等帶.Declinognathodus noduliferus和Streptognathodus isolatus的首次現分彆代錶賓夕法尼亞亞繫和二疊繫之底;Diplognathodus ellesmerensis, Idiognathodus sagittalis和J. simula-tor的首現則可分彆代錶莫斯科階(Moscovian),卡西莫伕階(Kasimovian)和格捨爾階(Gzhelian)之底界.作者較為詳細討論瞭巴什基爾階與莫斯科階以及卡西莫伕階與格捨爾階之界線,併認為以Diplognathodus ellesmerensis的首現作為巴什基爾階(Bashkirian)與莫斯科階之界線足目前最閤適的標誌.Diplognathodus ellesmerensis是一易于識彆、分佈廣汎及層位穩定的牙形刺種,其產齣又十分接近巴什基爾階與莫斯科階的傳統界線,因此是劃分此界線的良好標誌.作者擬推薦納水剖麵為莫斯科階底界之候選層型剖麵,這一界線詳細的工作正在大量採樣分析和深入研究中,成果將在以後陸續髮錶.

The Nashui section of Luodian, Guizhou is a good section for the study of the Pennsylvanian conodonts and the stage boundaries. This paper displays a new conodont succession from the mid-Carboniferous through the Carboni-ferous-Permian boundary as follows: the Gnathodus bilineatus bollandensis (Uppermost Mississippian), Declinog-nathodus noduli ferus, Idiognathoides sulcatus sulcatus, Id. Sinuatus, Id. Corrugatus-ld, pacificus, Neognathodus symmetricus, Idiognathodus primulus-Neognathodus symmetricus, Idiognathodus primulus-Neognathodus bassleri, Idiognathoides sulcatus parva, Streptognathodus expansus, Idiognathoides ouachitensis, Diplognathodus colora-doensis, Di. Ellesmerensis, Gondolella donbassica-Go, clarki, ldiognathodus podolskensis, Swadelina subexcelsa, Sw. Makhlina-Sw, nodocarinata, Idiognathodus sagittalis, Streptognathodus cancellosus, St. Gracilis, St. Guizhouensis, Idiognathodus simulator, I. Nashuiensis, Streptognathodus firmus, St. Tenuialveus, St. Wabaunsen-sis and St. Isolatus (Permian) zones. The bases of the Declinognathodus noduliferus Zone and the Streptognathodus isolatus Zone are the bases of the Pennsylvanian and Permian, respectively. The first occurrences of Diplognathodus ellesrnerensis, Idiognathodus sagittalis and I. Simulator represent the bases of the Moscovian, Kasimovian and Gzhelian, respectively. In addition, the Bashkirian-Moscovian boundary and the Kasimovian-Gzhelian boundary are discussed in detail. The first occurrence of Diplognathodus ellesmerensis as the beginning of the Moscovian Stage is a good proposal among proposals for the Bashkirian-Moscovian boundary. Diplognathodus ellesmerensis is easy to be recognized, widely distributed in the world, and has the stable horizon. Its first occurrence is very close to the tradi-tional Bashkirian-Moscovian boundary. We suggest that the Nashui section of Luodian, Guizhou to be a candidate for the global stratotype section and point for the base of the Moscovian Stage. The further study on this boundary is carying out and more detailed proposal will be submitted later.
