There are different kinds of fossils as one would imagine, but fossils that preserve an event are known as trace fossils. Fossils leave messages either by the imprint or by actually leaving behind DNA. This short article introduces the reader to the very basics of fossil formation. It is a simple read and would be a good source of information for a student and teacher as well.

Did you know that the dinosaur skeleton you see in a museum is not made of actual bone? This article, written by an expert, is a quick little summary of what constitutes a fossil. After reading you will have a better understanding of how fossils form and how their parts are replaced over time with minerals.
