This compilation of resources has no pretensions of being complete. Whereas some commercially-produced materials are included, the focus is on free and inexpensive materials and opportunities available both nationwide and locally. A large number of governmental organizations such as state geological surveys and professional organizations of paleontologists, geologists, and biologists have produced materials for distribution at minimal cost. In addition, many professional societies, state geological surveys, county to federal parks, and amateur societies provide educational opportunities “in the field”, where classes can visit fossils where they occur in nature, either to observe them or, where fossils are abundant and conditions are safe, to collect them to take back to the classroom for further study.
