Tuzoia.

Soft-bodied fossils of Cambrian age, now known as Burgess Shale–type biotas, were first described from the Parker Slate of the northwest Vermont (USA) slate belt in the late 19 th century, 25 years before the discovery of the Burgess Shale in British Columbia, Canada.

Tuzoia, which is known from a single Chengjiang specimen assigned to T. limba (Shu, 1990), superficially resembles Branchiocaris and Isoxys, and it may have had a similar life habit. Amiskwia, which is represented by one rare Chengjiang species, A. sinica (Chen et al., 2002) (Fig. 1 J), has fin-like structures.

Tuzoia typically occurs as laterally (lc) or dorsoventrally (dvc) compacted carapaces or single valves. Each type (lc or dvc) emphasizes particular aspects of the morphology (e.g., spiny lateral ridge, ventral margin) that were often interpreted as specific differences by previous authors. A revision of Tuzoia validates only 7 of the 23 named ...
