Digging Up Sea Creature Fossils

Sea creature fossils are particularly interesting because they're often found where there isn't any water. They give scientists insight into how Earth has changed over time and millions of years. Readers uncover some of the oldest sea creature fossils and find out how they formed, where they were found, and what they can tell us about the past, including where water once was and isn't anymore. Detailed photographs of these fossils correlate closely with accessible text and engage readers with eye-catching fossil examples.
