Abstract:
The known oldest footprint fossils discovered in the Three Gorges area, China have pushed ancient animals’ walking to 551 million years ago, providing evidence for the emergence of bilaterally symmetrical animals at the end of the Precambrian. It also provided meaningful information for the Cambrian explosion that may have begun before the Cambrian. This finding further enhances the value of footprint fossils in studying ancient animal behavior and understanding major biological events.
