These ichnofossil assemblages occurred within well-oxygenated, shallow-marine refuges in a Panthalassa Ocean otherwise characterized by widespread anoxia. We propose an environmentally controlled model for their distribution, in which wave aeration, enhanced by frequent storms, gave rise to an optimal zone for benthic colonization. Within this habitable zone extinction pressures were ameliorated and postextinction recovery duration was minimized.
