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.

Fossil Facts for Kids

  • Fossils are remains of plants and animals from the past.
  • They can be bones, teeth, or even footprints.
  • Most fossils are found in sedimentary rocks.
  • Fossils can be millions of years old.
  • Paleontologists are scientists who study fossils.
  • Dinosaurs are well-known for fossils.
  • Fossils help us understand Earth’s history.
  • Ammonites and trilobites are common fossils.
  • The fossilization process is very rare.
  • Some fossils show creatures in their environment.


You’d be amazed to discover, in the realm of paleontology, how scientists painstakingly unearth, study, and interpret fossils to reconstruct the history of life on Earth.

This fascinating area of study is all about digging deep into the past to find out about prehistoric life.

When you think of paleontology, you probably imagine dinosaur fossils, right? Well, you’re on the right track! Paleontologists indeed study dinosaur fossils, but they also examine fossils of plants, insects, and other animals that once roamed our planet.

The study of fossils isn’t just about old bones, it’s a journey back in time that helps us understand how Earth’s past shapes our present and future.

Isn’t it exciting to know that you’re living in a world that’s been billions of years in the making?


Imagine coming face-to-face with a towering T-Rex or a massive Brachiosaurus – that’s the incredible world of dinosaurs you’re stepping into! Dinosaurs roamed our planet during the Mesozoic Era, specifically the Cretaceous period. Can you believe it was between 66 and 145 million years ago?

Dinosaur bones are the most common fossils found, giving us clues about these fascinating creatures. They tell us how big dinosaurs were, what they ate, and even how they moved. The largest dinosaur fossil ever discovered was of an Argentinosaurus, measuring a whopping 100 feet long!

So, when you’re looking at those giant dinosaur bones in the museum, remember – they’re not just old rocks. They’re a gateway to a time when giants walked the Earth. Isn’t that just awesome?


Delving into the realm of geology is like cracking open the Earth’s secret diary, filled with tales of shifting continents, fiery volcanoes, and powerful earthquakes that’ve shaped our world’s stunning landscapes.

You’re suddenly a detective, piecing together Earth’s history by examining rocks – the Earth’s very own storybooks.

One fascinating type of rock you’ll come across is sedimentary rock. Imagine rivers, winds, or ice grinding down mountains and carrying the debris to new locations. Over time, layers and layers of this sediment build up, and with the help of pressure and heat, become sedimentary rock.

Each layer tells a unique tale about the Earth’s past. So, the next time you see a rock, remember, you’re not just looking at a rock, you’re looking at a piece of geology – a piece of Earth’s fascinating history!

Prehistoric Life

When we delve into prehistoric life, it’s as if we’ve been handed a time machine. It allows us to journey back to when dinosaurs roamed the Earth and mammoths were more than just figures in a museum. Imagine yourself walking in the same paths where dinosaur footprints were imprinted millions of years ago. These footprints are like a snapshot of their existence, providing valuable information about these extinct animals.

Prehistoric life was a time of gigantic creatures and extreme conditions. Plants and animals that are no longer with us today thrived back then. It’s fascinating to think about how different the world was.

So, next time you see a fossil, remember it’s not just a rock. It’s a window into a world long gone, a testament to the amazing prehistoric life.


Understanding evolution is not just about charting the path from primordial soup to the vast diversity of life we see today. It is also about unraveling the mysteries of how and why species change over time, adapting to their environments in a relentless pursuit of survival.

Fossils provide us with a window into these mysteries. They give us glimpses into the world of ancient life, showing us how evolution has shaped every creature, big and small, over billions of years.

When you find a fossil, you are not just holding a piece of rock. You are holding a piece of history, a snapshot of an organism’s life frozen in time.

So, next time you look at a fossil, remember that you are looking at evolution’s handiwork. It is a testament to the enduring power of life itself.

Extinct Animals

Peering into the past, we’re confronted with a myriad of extinct animals. Their tales are told through remnants left behind, and each one is a testament to nature’s ceaseless cycle of birth, survival, and inevitable extinction.

Some of these ancient animals have become familiar to us through the exciting field of paleontology. Take, for example, the towering dinosaurs or the woolly mammoths.

Imagine, if you will, being a kid again, digging in the dirt of your backyard and suddenly stumbling upon a dinosaur fossil discovery! You’ve literally unearthed a piece of history, a glimpse into a world millions of years older than your own.

This is the thrill that drives paleontologists. After all, each discovery teaches us more about these extinct animals and, in turn, our own place in the grand tale of life on Earth.

Sedimentary Rocks

When examining sedimentary rocks, you’re not just looking at plain old stones. Instead, you’re gazing into nature’s history book, with each layer narrating a unique chapter of Earth’s past.

Sedimentary rocks aren’t formed overnight. They are made from layers upon layers of mud, sand, and other materials that harden over millions of years. These layers can sometimes trap things like leaves, shells, and even dinosaur bones. That’s right, fossilized bones are often found in sedimentary rocks.

These trapped items become a type of fossil known as a body fossil, perfectly preserved for us to discover. So next time you’re out exploring, remember that you’re not just looking at rocks. Instead, you’re holding the pages of Earth’s history in your hands, waiting to uncover its ancient secrets.

Carbon Dating

Now that we’ve explored the fascinating world of sedimentary rocks, let’s take a leap into a scientific method that helps us decode the history of life on Earth — Carbon dating!

Carbon dating is a super cool way scientists use to find out how old a fossil is. Imagine being able to tell the age of a dinosaur bone or a piece of ancient wood! It’s like being a detective, but instead of solving crimes, you’re unraveling the mysteries of our planet’s past.

This method measures the amount of carbon-14, a special type of carbon, in a fossil. By doing so, it can tell us the period of time the creature or plant lived. So, carbon dating is like a time machine, taking us back millions of years!


Delving into the realm of archaeology is like stepping into a time portal. Every artifact whispers tales of civilizations long gone, echoing the triumphs and trials of our ancestors.

As you learn more about archaeology, you’ll find that fossil bones are an invaluable treasure trove of information. They provide a glimpse into the past, bringing extinct creatures back to life in our imaginations.

Common fossils, such as shells or plant imprints, can tell us about the environment of the past and the organisms that lived there. But it’s the fossil bones that often capture our attention. They can reveal the size, shape, and even the behavior of ancient animals.

So buckle up, young archaeologists. It’s time to uncover the secrets held by these remnants of the past!

Earth’s History

Let’s dive into Earth’s history, where each geological layer tells a tale of a different era, showing us how our planet has evolved over billions of years. When you think about Earth’s history, consider how the presence of fossils indicates changes over time.

Fossils are like a puzzle, providing essential fossil facts for kids and adults. They tell us about the different plants, animals, and climates that existed millions, even billions, of years ago.

For example, if we find a fossil of a sea creature in a desert, it indicates that location was once underwater. It’s fascinating, isn’t it?

So next time when you’re learning about our planet’s history, remember fossils are not just old rocks, they’re the key to understanding our Earth’s past.

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 for Kids

  • Without fossils, we wouldn’t know about dinosaurs.
  • Some fossils are of footprints or animal burrows, rather than the animals themselves.
  • Fossilized poop is called coprolites. Scientists have found coprolites from Tyrannosaurus rex dinosaurs that contain bits of crushed bones.
  • 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.

Fossils Vocabulary

  1. Decay: rot
  2. Remains: dead animal or plant material
  3. Fossil: any animal or plant remains that has been preserved for more than 10,000 years
  4. Coprolite: fossilized poop
  5. Resin: sticky sap from trees and plants
