Tuzoia canadensis was one of the pointier-looking tuzoiids, known from the Canadian Burgess Shale deposits (~508 million years ago). About 10cm long (4″), its carapace was lined with many long spines, with a more prominent spiky side frill than most other species. Its reticulated ornamentation had fairly large polygonal ...

The cephalic structures of Isoxys minor include a pair of large, rounded stalked eyes arranged apart (Hu et al., 2014, fig. 156; Fig. 1 h) and a pair of robust frontal grasping appendages with circa 6 podomeres (Fig. 1 a-c).
