Can a rock remember an animal?
How footprint fossils form. A true how-it-works story for kids 4–7.
The Fossil story, read aloud
On this road, we're driving past hills and houses. And inside some hills are rocks. Did you know some rocks hold a secret called a fossil? A fossil is a mark from an animal, saved in rock. Can a rock remember an animal? Let's see! A long, long time ago, before any houses or cars, a big dinosaur went for a walk.
It stepped in soft, squishy mud, like wet sand at the beach. It left a big footprint! Then it walked away. It did not wipe its feet. Here's how the magic happened. The mud dried in the sun. Then more mud covered it up, like a blanket.
Over a very, very long time, that mud got hard and turned into rock. And the footprint was still inside! Can you stomp your feet like a dinosaur? The dinosaur is gone now. But people still find its footprints in rocks, so the rock remembers.

Mud. Mud! Soft mud got hard, slowly, and became rock. Shells and bones can turn into fossils too.
