The Chaochuan Formation is a geologic formation in China (Zhejiang Province). It is made up of purplish red calcarenaceous, muddy siltstone, fine-grained sandstone with interbeds of tuffaceous sandstone and conglomerate or rhyolitic tuff.[1]

Fossil content

The following fossils were reported from the formation:

Dongyangopelta yangyanensis[2]
Therizinosauridae indet. (once known as "Chilantaisaurus" zheziangensis)[3][4][5]
Zhejiangosaurus lishuiensis[6]
