We talk about fossils a lot in this program. But what are fossils anyway? If you have no idea what fossils are, click on “What’s a Fossil?” If you want to see how paleontologists find out how old they are, click over there on “Dating Fossils”. There’s more to fossils than just bones. If you want to learn about other kinds of fossils, click on “Trackways” or “Trace Fossils”.
