Tozzia is a monotypic genus of flowering plants within the broomrape family Orobanchaceae.It contains a unique species, Tozzia alpina..

One species, Tuzoia bispinosa, is known from abundant material in the Kaili Biota (Cambrian Series 3, Stage 5). Based on 168.The largest Emu Bay Shale Tuzoia specimens with circular eyes preserved in situ show that these visual organs do not reach more than 9 mm in diameter (21, 26), and even the biggest Tuzoia carapaces from this deposit would not be able to accommodate acute zone-type eyes more than 3 cm in diameter.

Tuzoia canadensis. Tuzoia canadensis was one of the pointier-looking tuzoiids, known from the Canadian Burgess Shale deposits (~508 million years ago).
