Are you ready to learn some awesome dinosaur facts? When you think of dinosaurs, do you picture a fierce Tyrannosaurus rex, a gentle Brontosaurus, or a strong Triceratops? Dinosaurs are truly amazing creatures!
Let’s travel back over 200 million years ago to a time called the Mesozoic Era, also known as the Age of Reptiles. This era is divided into three periods: Triassic, Jurassic, and Cretaceous. Dinosaurs lived and changed during these times until a big event changed Earth’s climate, causing most of them to become extinct.
Extinct means that something is gone forever. Dinosaurs became extinct about 66 million years ago, long before humans existed. Scientists are still trying to figure out what caused this extinction. Some think it was because of many volcanoes erupting, while others believe a meteorite hit the Earth. Whatever the cause, it changed the climate so much that many living things couldn’t survive.
Even though dinosaurs are extinct, we can learn a lot from their bones and fossils. Did you know that when people in China first found dinosaur bones, they thought they were dragon bones? The word “dinosaur” comes from Greek words meaning “terrible lizard.” Imagine finding dinosaur bones for the first time!
Scientists who study dinosaur fossils are called paleontologists. They have discovered that most dinosaurs were reptiles, which means they were cold-blooded. Unlike other reptiles, dinosaurs had straight legs. Some dinosaurs, like the Allosaurus, walked on two legs, while others, like the Stegosaurus, walked on four.
Dinosaurs came in all sizes. Some were as small as chickens, while others were bigger than school buses. The Velociraptor was about the size of a turkey but had a powerful bite like a lion! Dinosaurs had different diets too. Some were herbivores (plant-eaters), some were carnivores (meat-eaters), and others were omnivores (ate both plants and meat).
Did you know some dinosaurs are related to birds? Dinosaurs that walked on two legs had hip bones similar to birds. Some, like the Coelophysis, even had a wishbone like modern birds. So, the next time you see a bird, think about its ancient dinosaur relatives!
Great job, dino explorers! The next time you watch a dinosaur movie, remember all the cool things you’ve learned. Even though dinosaurs have been gone for millions of years, they still teach us exciting things. Maybe one day, you’ll discover even more about these incredible creatures!

Dinosaur Detective: Go on a mini fossil hunt in your backyard or a nearby park. Look for interesting rocks and pretend they are dinosaur bones. Use a small brush to gently clean them, just like a paleontologist would. Discuss with a friend or family member what kind of dinosaur you think your “fossil” might belong to and why.
Dino Diet Discovery: Create a simple chart with three columns labeled “Herbivores,” “Carnivores,” and “Omnivores.” Use pictures from magazines or draw your own to fill in the chart with different dinosaurs. Discuss what each dinosaur might have eaten and why. You can also include modern animals that fit into these categories to see how they compare.
Birds and Dinosaurs Connection: Next time you see a bird, observe its features like the beak, feathers, and legs. Draw a picture of the bird and label its parts. Then, draw a dinosaur and compare the two. Discuss with a friend or family member how birds and dinosaurs might be related. What similarities do you notice?
Sure! Here’s a sanitized version of the transcript:

[Music] Are you ready for some dinosaur facts? When you hear the word “dinosaur,” what do you think of? Maybe a terrifying Tyrannosaurus rex comes to mind, or perhaps you are thinking of a brilliant Brontosaurus or a tenacious Triceratops. No matter what dinosaur you’re thinking of, they’re all pretty amazing!
There are lots of cool facts to discover about dinosaurs, so let’s take a journey back in time to learn more. The first dinosaurs lived over 200 million years ago during a time called the Mesozoic Era, which is also known as the Age of Reptiles. During this era, there were three smaller periods: Triassic, Jurassic, and Cretaceous. Dinosaurs evolved or changed over time until a huge event caused the planet’s climate to change, leading to the extinction of over 75% of all living things on Earth.
Extinct means that something is gone forever, which is why there are no dinosaurs around today. This all happened about 66 million years ago, long before any human beings lived on Earth. To this day, scientists are still not sure what exactly caused this extinction. Some think that there was a worldwide eruption of many volcanoes that clouded the atmosphere with ash and smoke. Others believe a meteorite struck the planet and caused significant damage. No matter what the cause, it changed the Earth’s climate so much that most life on the planet could not survive.
Even though dinosaurs are extinct, we can still learn lots of fascinating things about them. Here’s a fun fact: when the Chinese first found dinosaur bones many hundreds of years ago, they thought the bones were the remains of giant dragons. The name “dinosaur” comes from two Greek words that mean “terrible lizard.” Can you imagine what it would be like to discover dinosaur bones, especially if you had never seen anything like them before? That must have been pretty wild!
Skeletons, bones, and fossils are why we know so much about dinosaurs today. Over the years, scientists have made more discoveries and even had to change what they thought about how dinosaurs lived. Special scientists called paleontologists study dinosaur fossils and have helped create some general classifications or traits of dinosaurs. Because of paleontologists, we know that most dinosaurs were reptiles, meaning they were cold-blooded. We also know that their legs were straight instead of bent like other early reptiles, such as crocodiles, which is pretty interesting.
Some dinosaurs walked on two legs, like the Allosaurus and the Utahraptor, while others walked on four, like the Stegosaurus and the Apatosaurus (another name for Brontosaurus). Another cool fact about the Apatosaurus is that it laid some of the largest eggs of all the dinosaurs; each egg was about the size of a basketball! Size-wise, dinosaurs could be as small as a modern-day chicken or larger than a school bus.
Here’s a fun fact: the Velociraptor weighed only around 35 pounds, about the size of a turkey, but its bite was as powerful as a lion’s. Dinosaurs had different diets too. Some were herbivores, meaning they only ate plants; some were carnivores, which means they only ate meat; and others were omnivores, meaning they ate both.
If you were a dinosaur, what kind would you want to be? Here is another interesting fact: some dinosaurs are actually related to birds! What’s even more interesting is how you can tell which dinosaurs are like birds and which aren’t. It all comes down to their hip bones. Dinosaurs that walked on two legs have hip bones similar to birds. Some dinosaurs, like the Coelophysis, also had a wishbone just like modern-day birds.
So the next time you’re talking with your friends about cool dinosaur facts, you can tell them that both the T. rex and the Velociraptor are ancient bird ancestors. Now that we’ve learned some cool things about our extinct reptile friends, let’s review:
Fill in the blank: The word “dinosaur” comes from two Greek words that mean ______ lizard. (terrible)
True or false: Another name for the Mesozoic Era is the Age of the Reptiles. (true)
Name one of the three periods in the Mesozoic Era. (Triassic, Jurassic, or Cretaceous)
Fill in the blank: Meat-eating dinosaurs are called ______. (carnivores)
True or false: An Allosaurus walks on four legs. (false)

Great job, dino dynamos! The next time you turn on your favorite dinosaur movie, remember all of the cool things we have learned today. Even though dinosaurs have been extinct for millions of years, these fascinating creatures are still teaching us lots of exciting things. Maybe one day you will be the one to discover even more about our reptilian friends!
