We propose an oxygen-controlled trace-fossil model in which increasing oxygen concentration of interstitial water in sediment parallels a transition from fodinichnia-dominated through pascichnia-dominated to domichnia-dominated trace-fossil associations. In certain places, such as parts of the late Paleozoic Oquirrh Basin in Utah, this model provides a reasonable alternative to the more traditional, depth-controlled model of trace-fossil distribution.
