Zoophycos Ichnofacies The Zoophycos Ichnofacies is characterized by complex fodinichnia ( Zoophycos , and sometimes other deep traces such as Thalassinoides ) in tiered arrangements. Fossils are primarily found in sedimentary rocks because these rocks form at low temperatures and pressures. Igneous rocks form at temperatures and pressures that are high enough to destroy any organic remains.
