Species

Diagoniella is a genus of sponge known from the Middle Cambrian Burgess Shale. [1] [2] 128 specimens of Diagoniella are known from the Greater Phyllopod bed, where they comprise 0.24% of the community. [3]

Several specimens previously assigned to Diagoniella by Rigby (1983) [4] may have instead belonged to Polygoniella as per Del Mouro et al. (2024). [5]
