bivalved arthropods Isoxysand Tuzoia (Lower and Middle Cambrian) are two other potential thylacocephalancandidates making this group of arthropods a possible new component of Cambrian marine communities.

Diagrammatic reconstruction of Tuzoia in ventral view (a), with the carapace corresponding to T. burgessensis, this view is a diagrammatic reconstruction that emphasizes the boundary between the cephalothorax and the trunk.

However, no detailed structure of the visual surface is preserved in the articulated eyes of Emu Bay Shale or Burgess Shale Tuzoia specimens.The morphology of Tuzoia is reinterpreted in the light of abundant new specimens from the Middle Cambrian Burgess Shale (British Columbia, Canada) and Kaili (Guizhou, China) Lagerstätten. Tuzoia was a very large (up to 180 mm long) bivalved arthropod with a nonmineralized domelike carapace strengthened by prominent pointed features and often flanked by a lateral ridge bearing a spiny frill.
