Genus
Anoigmaichnus Vinn, Wilson, Mõtus et Toom, 2014
Taxon description
Vinn et al., 2024r
Diagnosis (emended): Short bioclaustrations perpendicular to the host’s growth surface or tilted (up to 45 °); conical to cylindrical; circular to oval cross-sections. Apertures with faint to well-developed rims on the growth surface of the host. Bioclaustratons begin with Trypanites or other bioerosional cavities.
Vinn et al., 2014e
Diagnosis. — Shafts perpendicular to host's growth surface or tilted (up to 45°); conical to cylindrical; circular to oval cross-sections; lacking
separate wall. The shafts cut through host's skeleton throughout most of their length. The apertures are elevated above host's growth
surface.
