FIGURE 8 Stylized model showing the development of a Seilacherian ichnofacies (e.g., Cruziana
Ichnofacies) and the five main uses to which it is put. Diagram modeled after Walker (1992) and

lithofacies, facies models, and obey Walther's Law, making their mappable dis-
tributions and occurrences in vertical successions predictable. Perturbations in
their predictable occurrence commonly indicate the presence of an omission
surface.
A fourth use of ichnofacies, as with physically based facies models, is that it
may act as an integrated basis for interpretation of the system that it represents
