通过对福建沙县高地村石灰岩矿区船山组类的系统研究 ,共描述类 13属 70种 ,包括 7个新种和 3个未定种。根据类在地层中的分布和垂向变化规律 ,自下而上建立了 5个类化石带 :1) Triticites shikhanensis com-pactus带 ,2 ) Pseudoschwagerina miharanoensis带 ,3) Zellia chengkungensis带 ,4 ) Sphaeroschwagerina sphaerica带 ,5 ) Eoparafusulina pararegularis带 ,为该区船山组地层的划分和对比以及我国石炭 -二叠系界线的深入研究提供重要的科学依据。
A systematic study of the ichthyanthidae in the limestone mining area of Shaxian Highland Village, Shaxian County, Fujian Province, describes 70 species of 13 genera, including 7 new species and 3 undetermined species. According to the distribution and vertical variation of in the strata, five -like fossils are established from bottom to top: 1) Triticites shikhanensis com-pactus, 2) Pseudoschwagerina miharanoensis, 3) Zellia chengkungensis, 4) Sphaeroschwagerina sphaerica belt, and 5) Eoparafusulina pararegularis belt provide important scientific evidences for the division and contrast of the Chuanshan Formation strata in this area and the in-depth study of the Permo-Carboniferous boundary in China.
