Taxon description

Wisshak et al., 2019a

Microboring; substrate calcareous; tracemaker invertebrate?

Wisshak, 2017

Emended diagnosis. Dendritic or rosetted boring network spreading immediately beneath the surface of calcareous skeletal substrates, with tunnels radiating and branching outward from a central node that shows deepest penetration of the trace and may expand into palmate fans. Tunnels taper, cross, or anastomose, andconnect to the substrate surface at their terminations or along th eir entire length.

Knaust, 2012a

Branched, rosetted.

Blissett & Pickerill, 2004a

Diagnosis (modified after Fenton & Fenton, 1932) — Borings, having small tubes radiating from a common centre, which may be single and pronounced, or multiple and indistinct. Tubes may expand into palmate channels, which commonly terminate in minute, radiating or irregularly branching tubes. The tubes may also be errant, coiled, crossing and anastomosing in patterns that almost obscure the centre of radiation.
