Taxon description

Wisshak et al., 2019b

Attachment; substrate calcareous; tracemaker invertebrate

Robinson & Lee, 2008

Emended diagnosis of ichnogenus. Podichnus . –More or less compact group or cluster of short pits, holes, elongate cylindrical shafts and/or furrows, mutually parallel or diverging, within carbonate substrates. Surface expression is a ca. 1–4 millimetre-sized cluster
of holes each up to ca. 200 μm in diameter.

Buatois et al., 2017

Category of architectural design: 2.77. Multiple attachment bioerosion traces.

Blissett & Pickerill, 2007

Diagnosis – (Emended after Bromley & Surlyk, 1973, pp. 363, 364.) More or less compact groups of pits or cylindrical holes in hard, calcareous substrates. The pits at the centre of the group are more or less perpendicular to the surface; the more peripheral pits typically deeper and larger, entering the substrate obliquely and centrifugally.

Knaust, 2012a

Unbranched, cylindrical, etching.
