When an animal or plant dies, it usually decays quickly. Dead animals are often eaten. Sometimes, though, an animal’s body sinks into thick mud. The mud contains no air so the remains don’t decay. Animals can’t disturb the remains.
Here the remains may rest for thousands or even millions of years. Over time, more mud presses down on the remains. Minerals dissolved in the mud turn the remains to stone. These remains are called fossils and they give scientists clues about what life was like on our planet.
Fun Facts About Fossils
- Without fossils, we wouldn’t know about dinosaurs.
- Some fossils are of footprints.
- It’s pretty unusual to find a whole fossilized animal. Scientists usually find shells, bones and teeth instead.
- Scientists have found fossils of feathered dinosaurs.
- Sometimes animal and plant remains are preserved, but they’re not turned to stone. Insects were stuck in sticky tree resin. The tree resin turned to amber over millions of years, but the insects are completely intact inside.
