Mollisonia
Mollisonia is a genus of epifaunal detritivorous arthropod. Species are known from the Cambrian Burgess Shale, Langston Formation and Wheeler Shale of North America, as well as the Chenjiang Biota of China.[1] Twenty-one specimens of Mollisonia are known from the Greater Phyllopod bed, where they comprise less than 0.1% of the community.[2] Remains attributed to the genus are also known from the Ordovician Fezouata Formation of Morocco and Greenland.[3] An observation published in 2019 suggests this genus is a basal chelicerate, closer to crown group Chelicerata than members of Habeliida. It is suggested to be closely related to Corcorania, Ecnomocaris and Thelxiope, together forming the clade Mollisoniida.[4]
