Stratigraphic range: Llandovery
Type Geological formation

Country  China
Type section
Named for Xiushan County

The Xiushan Formation is a palaeontological formation located in China. It dates to the Lower Silurian period. Studies of conodonts found in the formation suggests the lower member and main part of the upper member correspond to the Pterospathodus eopennatus Superbiozone, whereas the top of the upper member likely correlates with the Pterospathodus celloni Superbiozone.
