Chancelloria is a genus of early animals known from the Middle Cambrian Burgess Shale, the Comley limestone,[1] the Wheeler Shale,[2] the Bright Angel Shale[3] and elsewhere (such as Iran). 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.[4] 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.[5]
