新密煤田上石炭统cf.Teichichnus rectus的发现

A discovery of cf. Teichichnus rectus in upper Carboniferous strata in Xinmi coalfield

首次在河南新密煤田发现了华北晚古生代地层中罕见的cf .Teichichnusrectus(直形墙形迹,比较种)这一痕迹化石分子。本文简述了它的保存和结构特征,并试图划分其痕迹类型和群落,推断其造迹生物,探讨其发育机制。此发现对研究海相岩层风暴沉积及其地层划分与对比具有十分重要的意义。

The trace fossil cf. Teichichnus rectu s, which could be seen infrequen tly in the Late Paleozoic strata of North China, was found for the first time in Xinmi coalfield of Henan Province. In this paper, the authors described the fea tures of its conservation and structure, tried to divide its trace types and coe noses, inferred its living things, which made traces, and discussed its developm ent mechanism. This discovery is very important for study of the storm deposits of the marine and the division and correlations of the strata.
