Fig. 9 in The Early Cambrian origin of thylacocephalan arthropods

Fig. 9. Interpretation of possible Early Cambrian thylacocephalans as nektonic organisms living in the lowermost levels of the water column in a shelf marine habitat (max. bottom depth ca. 100–150 m). A. Isoxys (after Vannier and Chen 2000, modified; possible prehensile appendages after Hu 2005). B. Tuzoia (after Vannier et al. in press). C. Zhenghecaris gen. nov. Members of the benthic (1; selkirkiid worms), epibenthic (2; arthropods Fortiforceps and Kunmingella) and nektobenthic communities (3; waptiids); wsi, water−sediment interface. Not to scale.
