The field of ichnology (the study of animal-sediment relationships) is undergoing rapid expansion. Increased significance is being attached to trace fossils in environmental and diagenetic interpretations of rock units and in establishing basic stratigraphic frameworks. The subject, therefore, is of importance not only for ichnologists but also for invertebrate and vertebrate paleontologists, paleoecologists, sedimentologists, stratigraphers, and resource geologists. The main purpose of this workshop is: a) to introduce the basic concepts of ichnology; b) to learn how to recognize basic types of trace fossils in core; c) to place these structures in their appropriate paleontologic, sedimentologic, and stratigraphic content; and d) to integrate this data with other lines of evidence to aid in petroleum exploration.
