There are many ways to identify a fossil. The easiest the easiest fossils to identify are fossil seashells because of their similarity to modern seashells. The other most common fossil is teeth, shark teeth are at the top of the list. There are great online resourced where one can post a picture of their find to get it identified. Our favorite is The Fossil Forum

Other great ways to get your find identified is to attend one of the many rock shows in your area. There are always a number of experience and knowledgable dealers there that are more than happy to help. This is another great resource, Paleontological Society
