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.[1]
