Trace fossils represent both sedimentologic and paleontologic entities and, as such, represent a unique blending of potential environmental indicators in the rock record. Trace fossils and trace-fossil suites can be employed effectively to aid in the recognition of various types of discontinuities and to assist in their genetic interpretation. Ichnology may be employed to resolve surfaces of sequence stratigraphic significance in two main ways: (1) through the recognition of substrate-controlled ichnofacies, which mark time gaps between the original deposition of a unit (with or without softground burrowing) and later superimposition of a postdepositional trace-fossil assemblage, and (2) through careful analysis of vertical ichnological successions (analogous to facies successions). Integrating the data derived from substrate controlled ichnofacies with data from vertical ichnological successions provides a powerful tool for the recognition and interpretation of important sequence stratigraphic surfaces.

Sequence Stratigraphy of Foreland Basin Deposits: Outcrop and Subsurface Examples from the Cretaceous of North America
A comprehensive collection of papers presenting the rapidly evolving opinions and viewpoints about sequence stratigraphy concepts and applications. Using the foreland basin setting as the common theme, the ideas presented here carry a much broader significance and can be applied to many other basin types. Also includes a glossary of sequence stratigraphy terms. In summary, this book is an invaluable addition to the sequence stratigrapher or indeed any geologist dealing with siliciclastic successions, it provides a tremendously detailed reference which can be ‘dipped into’ time and time again.
