Millions of years ago, a creature called an ichthyosaur (IK-thee-uh-sor) swam in the sea. It had long jaws with sharp teeth. It chomped on fish as it swam.
But one day, it died. Its body sank into the mud at the bottom of the sea.
Over millions of years, its flesh rotted and its bones turned into rock. It became a fossil. A fossil is what is left of animals and plants from many, many years ago.
More changes happened. Its watery home became dry land. Now it was no longer a fossil under the sea. It was a fossil in a cliff.
No one knew it was there. Then a girl named Mary Anning came along.
