The ichnofossils Treptichnus and Multina provide clues about the development of behavior in burrowing metazoans. A particular behavior type may be condensed and superimposed on the original burrowing pattern of programmed behavior. For example, a fine scale sinusoidal pattern may be superimposed on a large scale sinusoidal pattern.

Trace fossils, sedimentary structures resulting from animal activity, cannot compete with body fossils when it comes to taxonomic resolution. Traces, or 'Lebensspuren', also have the advantage that they cannot be reworked to become redeposited outside the original habitat or as ghost fossils in deposits of much younger age.

Trace fossils are normally preserved at or near interfaces, as a result of burrowing or crawling activity along the junction of successive beds of different lithology. The traces may be enhanced by diagenetic concentration of such minerals as calcite, chert, and pyrite, and hence may appear as concretionary nodules. The scour-fill activity of turbidity
