| Abstract: |
| Abundant metazoan trace fossils were discovered for the first time from the Changchengian Zhaojiazhuang Formation in the southern part of the Taihang Mountains. These trace fossils include the burrows and crawling traces are preserved in the consequent bedding plane or in the bedding plane nearly perpendicular to rock beds. They are dated at 2000 Ma B. P., and rich in type, well preserved and well defined. The discovery of these Mesoproterozoic trace fossils is important to the examination of the derivation and evolution of the metazoans. |
