Pirania is an extinct genus of sea sponge known from the Middle Cambrian Burgess Shale and the Ordovician Fezouata formation. [3] It is named after Mount St. Piran, a mountain situated in the Bow River Valley in Banff National Park, Alberta. It was first described in 1920 by Charles Doolittle Walcott. [4] 198 specimens of Pirania are known from the Greater Phyllopod bed, where they comprise 0.38% of the community. [5]
