Priscansermarinus barnetti is an organism known from the Middle Cambrian Burgess Shale which was originally interpreted as a species of lepadomorph barnacle. [2] [1] 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]

Etymology

The genus name, Priscansermarinus, is a combination of the Latin priscus ("of ancient times"), anser ("goose"), and marinus ("sea"). It roughly translates to "sea goose", referring to the lepadomorph barnacles it was originally assigned to. [1]

The sole species, P. barnetti, is named after Robert Barnett, a member of the Royal Ontario Museum’s 1975 inaugural Burgess Shale expedition, where 62 specimens were discovered in a slab buried beneath scree. [1]
