一、前言江苏南部的船山组、出露广泛、剖面良好,丹徒县船山是船山组创名地点。船山组富含以(?)和四射珊瑚为主的化石群。■类化石经陈旭教授早年研究、其面貌已披露于世,但四射珊瑚却未见前人报导。鉴于晚石炭世的四射珊瑚在研究石炭纪和二叠纪四射珊瑚动物群的演化关系及对比晚石炭世地层时都具有重要意义,所以在船山组中系统采集并详细研究四射珊瑚化石是当前古生物工作的重要课题之一。

Chuanshan Formation is rich in (?) And coral-based fossils. ■ fossils by Professor Chen Xu early years of study, its face has been disclosed in the world, but coral coral has never been reported before.
