Chancelloria

Chancelloria is a genus of early animals known from the Middle Cambrian Burgess Shale, the Comley limestone,[4] the Wheeler Shale,[2] the Bright Angel Shale[5] and elsewhere. It is named after Chancellor Peak. It was first described in 1920 by Charles Doolittle Walcott, who regarded them as one of the most primitive groups of sponges.[6] However, they are currently thought to be member of the group Chancelloriidae. 178 specimens of Chancelloria are known from the Greater Phyllopod bed, where they comprise 0.34% of the community.[7]
