Ichnotaxon

Ichnotaxa are names used to identify and distinguish morphologically distinctive ichnofossils, more commonly known as trace fossils. The binomial names of ichnospecies and their genera are to be written in italics.

It is important to note here that exactly the same ichnotaxon co-occurs with phosphatized soft-tissues in schizodont bivalves of the same age (Klug et al., 2005).

Parallel to the osteological record of phytosaurs, the ichnotaxon Apatopus lineatus reflects a widespread group of archosaurs living in habitats that only randomly overlapped those of fully terrestrial chirotherian trackmakers.

In a note, Donovan (2015) cast doubt on the establishment of the ichnotaxon K. crusta by Klompmaker et al. (2014) for the branchial swellings exemplified in Figure 1.
