Taxon description
McLoughlin et al., 2009
Diagnosis. Unbranched tubes with a coiled or helical axis (Fig. 5), with up to 12 whorls (i.e. complete rotations), but they normally show fewer than this and may be either sinistrally or dextrally coiled. Tubulohyalichnus spiralis isp. nov. may show a linear or curved growth axis with the spacing and diameter of the whorls changing along its length.
Differential diagnosis. The only tubular ichnotaxa in volcanic glass that has a helical axis
