Description(s)
Bromley, 1981a:
Diagnosis: Oichnus having a spherical paraboloid form, truncated in those cases where the boring penetrates right throueh the substrate. Where it does not so venetrate, the parabYoloill rnay be deformed by a slightly raised central boss.
Blissett & Pickerill, 2007:
Diagnosis – (After Bromley, 1981, p. 62.) “Oichnus having a spherical paraboloid form, truncated in those cases where the boring penetrates right through the substrate. Where it does not so penetrate, the paraboloid may be deformed by a slightly raised
central boss.”
Description – Simple borings resembling overturned cones with the apexes truncated. The structures are perpendicular to the substrate surface.
Pokorný & Štofik, 2017:
Emended diagnosis: Penetrative Sedilichnus having a conical form, truncated where the boring penetrates through the substrate (after Bromley, 1981; and Zonneveld and Gingras,2014).
