Genus
Herpystezoum Hitchcock, 1848
Taxon description
Buatois et al., 2017
Note. Herpystezoum has been maintained as a valid ichnogenus by Rainforth (2005), but H. marshii and H. intermediumare probably undistinguishable from Gordia marina, whereas H. minutum is identical to Helminthoidichnites tenuis.
