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.
