Ichnofossilia Helminthopsis in Formatione Loganiana (Carboniferum Inferius) Wooster in oppido Ohii.
Ichnofossilia Helminthopsis in nucleo e Belridge Diatomite (Miocaenum Superius) in Lost Hills Oil Field Californiae.

Helminthopsis est ichnogenus cuiusdam ichnofossilis quod in planitiebus saxorum sedimentariorum reperitur. Eius proprietates maximi momenti sunt vestigia brevia, curvilinearia, non ramificata, lateribus parallelis, sine lineis in superficiebus saxosis. Repraesentare putatur submarina vescendi vestigia ab organismo invertebrato facta qui victus petens superficies substratorum lutulentorum colebat.[1][2] A Gordia (flexuosa, lateribus parallelis, sine lineis) distinguitur quia se numquam transgreditur.[3]
