On the basis of their age and co-occurrence with the body fossils of the probable trace-maker, most of Palaeozoic Cruziana traces have been attributed to trilobites (Seilacher 1970), but some Cruziana are considered as produced by aglaspidids (Fischer 1978), brachiopods (Bromley & Asgaard 1979), as well as vertebrates (Shone 1978).
