Crumillospongia

Crumillospongia is a genus of middle Cambrian sponges known from the Burgess Shale and other localities from the Lower and Middle Cambrian.[2][3] Its name is derived from the Latin crumilla ("money purse") and spongia ("sponge"), a reflection of its similarity to a small leathery money purse. That is, it has a saclike shape, and its wall has holes of two sizes, with a well-developed internal canal system. [2] 49 specimens of Crumillospongia are known from the Greater Phyllopod bed, where they comprise 0.1% of the community.[4]
