Isopodichnus

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.
