摘要:

沙洲地区沙1井牙形石可划分为两个化石组合带:(1)Neogondolella subcarinata subcarinata-Neog. subcarinata elongata带,代表长兴组下部;(2)Neog. Subcarinata changxingensis-Neog. Carinata带,代表长兴组上部。

Abstract:

Abundant conodonts were found in the Changxing Formation of the upper Permian at well Sha-1 in Shazhou legion, Jiangsu Province. These conodont fossils they be divided into 2 assemblage zones: 1.Neogondolella subcarinata subcarinata- Neog. subcarinata elongata represente the lower part of the Changxing Formation, and it may be contrasted with Gondolella subcarinata named by H. Kozour in 1978,and Anchignathodus typicalis found by Clark in 1977. 2.Neogondolella subcarinata chongxingensis-Neog. carinata represent the upper part of the Chengxing Formation. The fauna has relatively particular features and local specialities. It may be the youngest stratum of the Permianin the world.
