Zoophycos is a complex and enigmatic ichnofossil that has challenged generations of geologists and ichnologists for over a century.Beds with Cruziana are typically composite. Burrows were sometimes washed out and then recast by sand with primary structures. Formation as open surface furrows on an eroded and firmed mud, as postulated by others, is sedimentologically plausible in some instances but is unproven and seems biologically unlikely.
