摘要
云南省梅树村震旦系—寒武系界线层型剖面中有丰富的遗迹化石。根据造迹生物的行为方式,将化石分为停息迹、居住迹、觅食迹和行移迹四大类。在形态上有单槽型、双槽型、分枝型、环圈型、简单潜穴型。对剖面中自下而上遗迹化石形态和组合特征的分析,认为本区的环境演变经历了潮间—潮下浅水—潮间—潮下较深水的变化过程。
The morphological property, classification and distribution of the horizontal trace fossils collected from the Sinian-Cambrian boundary beds at Meishucun section are discussed and the behaviour patter analysis has been done for several typical ichnogenera. It is briefly illustrated that the trace fossils can be used for the palaeoenvironment restoration based on the relationship that trace maker depends on the environment.
