Mollisonia

Mollisonia is a genus of epifaunal detritivorous arthropod known from the Middle Cambrian Burgess Shale. Twenty-one specimens of Mollisonia are known from the Greater Phyllopod bed, where they comprise less than 0.1% of the community.[1] An observation published in 2019 suggest this genus is a basal chelicerate, closer to crown group chelicerata than members of Habeliida.[2]
