Sedilichnus spongiophilus Müller, 1977

Taxon description

Pokorný & Štofik, 2017

Diagnosis: Sedilichnus consisting of smooth-walled, bowl-shaped pits with a circular outline and rounded edge (Zonneveld and Gingras, 2014).

Wisshak et al., 2015

However, Sedilichnus is nomenclaturally unavail able, because it is an atelonym (conditionally proposed). In addition, reinvestigation of the type material of ‘Sedilichnus’ shows that it probably describes variably shaped oscula and thus is a genuine morphological character of the host sponge Prokaliapsis janus, rather than a bioerosion trace fossil.
