diverse assemblage that includes abundant Phycosiphon, Planolites, Helminthopsis, Chondrites, Zoophycus and Teichichnus. In contrast, the intervening reservoir section shows a restricted trace fossil assemblage, with common Planolites and Phycosiphon, as well as frequent cryptic bioturbation. Traces in the reservoir section are stunted, and …The Zoophycos ichnofacies ideally is found in circalittoral to bathyal, quiet-water marine muds or muddy sands, below the storm wave base, particularly in shelfal to slope areas (MacEachern et al., 2007, MacEachern et al., 2012; Buatois and Mángano, 2011, Fig. 12). Settings are generally free of turbidity flows and subject to oxygen deficiencies.
