 Description:
This unusual arthropod is known as  Candaspis
lavigata. The systematic position of this taxon has undergone several
revisions. It has affinities with the younger Canadaspis perfecta,
the type species. While it has been thought by some to be a crustacean,
most think that is not the case, and that its primitive level of
organization places it close to Fuxianhuia
and its kin.
