摘要：

在遗迹化石中,Zoophycus Massalongo(动藻迹)是一类发现较早,地层和地理分布相当广泛的生物成因构造;据文献记载,化石记录见于奥陶纪到第三纪世界各地的海相地层。由于 Zoophycus 形态构造比较特殊,个体较大,往往斜穿地层层面,很难采到完整的化石标本,因此,对其造迹生物、形成机制,迄今还没有完全解决。对其沉积环境以及分类都还缺乏系统整理和进一步的工作。我国各时代地层中的 Zoophycus,过去更无人问津。作者发现该类遗迹化石在石炭纪煤系地层中分布相当普遍,且对沉积环境具有一定的指示意义。

Abstract:

Trace fossil Zoophycus is widely distributed in shallow marine limestones of the Datang Fm of Lower Carboniferous in southern China,and the Middle Carboniferous Benxi Group and the Upper Carboniferous Taiyuan Group in northern China.Study of Zoophycus is of great importance for understanding environments of coal formation,they are often found in Carboniferous sediments of the Yangtze and Sino-Korea platforms,belonging to shallower marine environment.In this paper,4 ichnosp.of Zoophycus were described.They are Zoophycussp.1 from Lower Carboniferous,Zoophycus sp.2 and Zoophycus(palaeospira)wudaensis Yang ichnosp,nov.from Upper Carboniferous.
