'''''Isopodichnus''''' is an ichnogenus of trace fossil. Ribbon-like in form, ''Isopodichnus'' traces were likely formed by the activity of an isopod crustacean foraging within the preserved sediment. Parallel to the bedding plane, a central furrow is flanked by two hypichnial ridges. Trails may also exhibit scratch marks and be associated with ''Rusophycus''-like resting traces. ''Isopodichnus'' are very similar in form to ''Cruziana'' traces, making delineation of the two forms difficult, and controversial.<ref>Richard G.
