Takakkawia is a genus of sponge in the order Protomonaxonida and the family Takakkawiidae. It is known from the Middle Cambrian Burgess Shale that reached around 4 cm in height. [1] Its structure comprises four columns of multi-rayed, organic spicules (perhaps originally calcareous or siliceous) that align to form flanges. [2] The spicules form blade-like structures, ornamented with concentric rings. [2]
It was first described in 1920 by Charles Doolittle Walcott. [3] Takakkaw Falls which mark the start of the trail to Fossil Ridge. [4] 1377 specimens of Takakkawia are known from the Greater Phyllopod bed, where they comprise 2.62% of the community. [5]
