近年来，在我国前寒武纪不同时代的地层中发现了大量的痕迹化石，其中前寒武纪冰期前的痕迹化石主要分布于我国北方的长城纪和青白口纪地层中。这些痕迹化石产出时代古老，表明在我国北方１４～１７亿年前的海水中就可能生活有古老的后生动物，这些痕迹化石的发现对于探索后生动物的起源及演化具有重要意义。前寒武纪冰期后所发现的痕迹化石主要分布于我国西南地区震旦纪晚期的地层中，这些痕迹化石在震旦纪地层中的广泛分布，对震旦系及震旦系与寒武系界线的划分对比将提供重要依据。
In recent years, a great deal of trace fossils have been found in the strata of different Precambrian times in China. Among them, the trace fossils before the Precambrian glacial period are mainly distributed in the Great Wall Jihe and Qingbaikankai strata in northern China. These ancient traces of fossil output have shown that ancient metazoan animals may live in seawater from 14 to 17 billion years ago in northern China. The discovery of these trace fossils is of great significance in exploring the origins and evolution of metazoans. The traces of fossils found after the Precambrian glacial period are mainly distributed in strata of the Late Sinian in the southwest of China. These trace fossils are widely distributed in the Sinian stratigraphy. They are of great significance to Sinian and Sinian and Cambrian The division of boundaries will provide an important basis for comparison.
