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.

Mary Anning and her fossil

In 1799, Mary was born in a tiny town in England. As she grew, she loved to spend hours walking with her father along the beach and cliffs near their house. This area was famous for its strange shells and rocks. Mary and her father would gather these. He would sell them to make money. 

Then a terrible thing happened. When Mary was about 11, her father died. The family was left with no money. 

Mary knew she had to help. She kept walking the beach and cliffs. She searched for unusual rocks and shells. She wanted to sell them and help her family. 

Soon she found something that would help her family—and change the way people understood ancient creatures.

the cliffs of Lyme Regis, England, where the fossil was found

One day, Mary’s brother spotted something shocking on the beach. It looked like a huge skull in the sand. Mary knew she had to uncover the rest of it.  

Mary carefully chipped away at the rock around the skull. 

She soon realized it was part of 

a whole skeleton. She worked hard to uncover it. It took her months. 

Finally, she uncovered the whole thing. It was not a creature that anyone had ever seen before. It had a lizard-like body. 

It had flippers like a dolphin. 

It had a tail like a shark! 

It was 17 feet long. That’s longer than four second-graders!  

Mary had found an amazing fossil. It was a skeleton that had turned into rock.  

She sold the fossil. This earned her enough money to feed her family for months. The fossil was put on display at a museum. 

Mary’s fossil seemed like a monster from a storybook. But, over time, people would learn that it was a real animal from millions of years ago. 

It was an ichthyosaur. It lived about 200 million years ago, when dinosaurs roamed Earth.

Ichthyosaurs swam in the oceans. 

 

Today we know of about a thousand kinds of dinosaurs. There was the fierce Allosaurus, with its huge jaws. There was the tall Brachiosaurus, which ate leaves. And, of course, the lightning-fast Dilophosaurus

We can read book after book about incredible creatures that lived long ago. 

But no one knew any of that when Mary discovered her fossil. No one had heard of dinosaurs. The word dinosaur did not even exist. 

People had found fossils before the 1800s, of course. But no one knew what they were.

Mary’s discovery helped create a new field of science. It is called paleontology. That is the study of fossils. 

After Mary found her ichthyosaur, she continued to hunt for fossils. She would carefully excavate them. That means dig them out. She studied them too. She filled notebooks with drawings and observations. 

As the years went by, Mary made other important fossil discoveries. She found a flying reptile called a Dimorphodon. She was the first to find a complete skeleton of a sea reptile called a Plesiosaurus

She also studied coprolites. Those are pieces of fossilized poop!

Every year, people learn more about these long-ago creatures.

Plus, people find new fossils all the time. Anyone could find a fossil. You could find one!

Just think. Perhaps at this very moment, there is a kid walking on a beach somewhere, about to make a discovery that will change our ideas yet again. Just like Mary Anning.

How a Fossil Forms

It takes millions of years for a fossil to form.

Step 1: An animal like an ichthyosaur dies.





Step 2: Over time, its skeleton gets buried under water, mud, and rocks. It hardens into a fossil.





Step 3: After more time passes, the water dries up. Some of the dirt wears away. People can now find the fossil.
