This paper studies the ecostratigraphy and establishes 7 community zones (CZ), in ascending order, Sinoplatysomus-Geinitzina-Clarkina subcarinata, Tapashanites-Nodosaria-Clarkina subcarinata, Crurithyris-Geinitzina-Clarkina subcarinata, Glomospira-Clarkina changxingensis, Colaniella-Clarkina changxingensis, Rotodiscoceras-Palaeofusulina-Hindeodus typicalis, Clarkina meishanensis-Hypophiceras .The habitat type (HT) is different from upper shallow sea to the lower part of the lower shallow sea.展开更多
