对福建顺昌石炭—二叠系界线附近的类动物群进行了系统研究,共鉴定并描述了类8属24种。根据它们在地层中的分布和垂向变化规律,自下而上建立4个带:①Triticites shikhanensis compactus带;②Pseudoschwagerina galatea带;③Sphaeroschwagerinasphaerica带;④Eoparafusulinaconcisa带。通过与我国华南沉积区同期类生物地层的对比,解决了该区地层的时代归属。

A systematic study was carried out on the fauna in the vicinity of the Carboniferous-Permian boundary in Shunchang, Fujian Province, identifying and describing 24 species of 8 genera in China. According to their distribution in the strata and vertical variation, four  belts were established from bottom to top: ①Triticites shikhanensis compactus zone; ②Pseudoschwagerina galatea zone; ③phaeroschwagerinasphaerica zone; ④Eoparafusulinaconcisa zone. By comparing with the same biota in the sedimentary area of ​​South China in the same period, we have solved the age attribution of strata in this area.
