Rugose coral fauna of the Sifengya Formation included 18 genera and 34 species, while Daluzhai Formation with nine genera, ten species. We described rugose …Carboniferous rugose corals are useful for palaeoecological, palaeoenvironmental and palaeogeographic studies.

A rugose coral is a type of ancient coral which has a ribbed, often convoluted or scalloped, skeleton.
