Zoophycus在贵州下石炭统发现

The Discovery of Zoophycuses in Lower Carboniferous Series in Guizhou

本文介绍了贵州龙里地区下石炭统祥摆组和旧司组中的Zoophycus遗迹化石;在介绍前人对Zoophycus研究成果的基础上,依据Zoophycus在不同水深的沉积中都有出现这一事实,指出Zoopyhcus不能作为环境水深的指相遗迹化石,并从理论上作了论证。

A lot of zoophycuses have been found in the Xiangbai Formation and the Jiusi Formation of Lower Carboniferous series in Londi, Guizhou. The Xiangbai Formation is composed of littoral siltstone, quartz sandstone, shale, carbonaceous shale and coal. The Jiusi Formation is composed of limestone mixed up with sandstone, silicolite and siliceous shale. The zoophycus has also been found in large numbers in bathyal deposits. The fact shows that zoophycus cannot have originated in a deep water environment. In fact, trace fossil features are not only related to sea depths, but also to bottom bed types, energy conditions,f ood supplies, preservation state, much or less oxygen and moving habits of the living things.
