Podichnus Bromley et Surlyk, 1973

Attachment; substrate calcareous; tracemaker invertebrate

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.

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

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.

Unbranched, cylindrical, etching.
