In the standard section of ancient mountaineering group “Zhuchak Formation” of the late Proterozoic, it was found that three of the three layers contained fossilized chitin fossils, and the two lower layers produced the same. And Cyathochitinasp., The upper fossil layer, Conochitinasp., And Rhabdachitinasp., Indicate that the age of the “group of climbers and bamboos in the mountain climbers” belongs to the Paleozoic. This new finding is of great significance to the redetermination of the “Banxi Group” Geotectonic pattern and its evolution history is of great significance
