The advancement of ichnological research has left in its wake a considerable volume of literature that contains many important concepts and the results of some excellent field studies. These notes try to consolidate the most salient topics of the discipline and emphasize the application of ichnological concepts and data to geological problems. In many respects, a detailed knowledge of trace fossil concepts is a matter of experience rather than education. Trace fossils, unlike other fossils, are part of the rock and, thus, they are difficult to collect and curate. As a result, interested geologists must go to the field and see a lot of trace fossils in a variety of different views, preserved under a variety of different conditions, to build a working expertise on such structures. This short course is designed to suit the needs of a diversified audience, which is made up of geologists from both academic and industrial institutions. Although the primary concern is to introduce the subject to those having little background in ichnology, the hope is to also update those geologists who already use trace fossil information in their investigations.
