Tuzoia australis is an extinct species from the genus Tuzoia with an uncertain position within the arthropods (Arthropoda).
features
Tuzoia australis had an egg-shaped outline (length to height ratio of 1.55) and a carapace length of 37 mm. Both rostra were short, pointed, and about the same size. The notch was flat. The rear edge was slightly convex and had a thorn. The lateral line was very faint or absent. The net-like structure of the surface was even and very fine-meshed over the entire side surface.
Locations
Only 4 poorly preserved tanks were found in the Lower Cambrian Emu Bay schist in Australia .
Systematics
The species was first described by Martin F. Glaessner in 1979 and differs from other species of the genus Tuzoia in its smaller size, the rather fine-meshed net-like structure and the barely developed spines.
