Taxon description

Description. Only few somewhat doubtful specimens of this otherwise very common ichnospecies were encountered which showed the diagnostic club- to sack-shaped morphology (10-20 µm in length) and in one case a moderate collar around its neck (Fig. 8F), but did not display thin interconnecting substrate-parallel galleries.
