Priscansermarinus barnetti is an organism known from the Middle Cambrian Burgess Shale which was originally interpreted as a species of lepadomorph barnacle. [1] [2] Four specimens of P. barnetti are known from the Greater Phyllopod bed. [3] A reflective area originally interpreted as external plates has been reinterpreted as a more complex structure inside the body; Derek Briggs, a leading authority on the arthropods of the Burgess Shale, has questioned its assignment as a barnacle or even an arthropod. [4] The World Register of Marine Species places Priscansermarinus in Multicrustacea without assigning a class or order. [5]
