Dinosaur Fun Facts for Kids

"Let's take a trip through history and discover more about these marvelous prehistoric animals. Click here for fun dinosaur facts for kids."

The word dinosaur comes from the Greek words “sauros,” for a lizard, and “deinos,” meaning terrible. When Sir Richard Owen coined the term dinosaur in 1841, he was translating a Greek word into English. He chose this name because he believed dinosaurs to be reptiles like lizards or serpents in terms of their appearance. 

He chose the name based on his studies of fossilized bones and impressions of prehistoric creatures that scientists had found up until that point in history. The word dinosaur means “terrible lizard” but sometimes refers to a group of extinct reptiles. They lived during the Triassic, Jurassic, and Cretaceous periods (252 million years ago). This group includes crocodiles, birds, pterosaurs, and dinosaurs. For example:

  • Brontosaurus were land animals with thick legs like elephants but shorter bodies like giraffes
  • Triceratops had horns above its eyes like rhinoceros 
  • Stegosaurus, which had plates along its back instead of spikes 
  • Ankylosaurus, which resembled an armored tank due to its boney armor covering most parts of its body, including its tail

Dinosaurs Were as Tall as Two-Story Buildings

If you think about it, that’s pretty incredible. But wait, there’s more! The tallest dinosaur was the Argentinosaurus—it was around 100 feet long and weighed 200 tons. That’s the height of a 25-story building.

Think about the size of your house, then imagine a creature that is 100 feet tall. And some of the biggest dinosaurs weighed over 100 tons. That’s more than the weight of 20,000 people. And if that creature is also a carnivore, it eats people.

They were also very powerful. Some dinosaurs could run at speeds up to 50 miles per hour, about twice as fast as a horse. A team of scientists at the University of California, San Diego, discovered the largest dinosaur in Argentina. Titanosaurs include the Argentinosaurus, herbivores of South America, and the largest known dinosaur.

There are only about 200 fossils from this type of dinosaur today. These small numbers make it difficult for scientists to estimate their size and appearance. Scientists noted that these fossils had provided valuable insight into how they lived their lives—and how they died out 65 million years ago.

Camouflaged Like Chameleons Helped Dinosaurs Survive in Prehistoric Times

Camouflage is one of the many amazing facts about dinosaurs that make them fascinating. Scientists at the University of Manchester in England found evidence of the discovery. They used computer modeling to come to this conclusion. The researchers said that the dinosaur’s color patterns might have changed depending on what time of day it was or if they were standing in direct sunlight or shade.

Like you love to match your clothes, dinosaurs might have had a thing for matching. Many fossils show that dinosaurs sported bright colors. A dinosaur’s color could serve as camouflage, attract mates, warn others of danger, or regulate their body temperature, while others showed off their status in the pack.

The color of the dinosaur’s skin was very important because it helped them protect themselves from predators and harmful sun rays. Some experts believe that these ancient reptiles were able to change color for different purposes.

The researchers examined fossils from over 100 different species of dinosaurs. They found that many of them had traces of melanin—a pigment found in human skin. Researchers examined modern animals with melanin-based coloration. They found that many were hunters, such as frogs and octopuses. This discovery led them to believe that dinosaurs may have had camouflage abilities. These abilities are like those seen today in amphibians or reptiles.

T-Rex Could Run as Fast as a Race Car 

You might think that T-Rexes were slow, lumbering creatures, but you’d be wrong. Their speed was comparable to that of a race car. Scientists had recently discovered that these dinosaurs could walk at speeds of up to 6 miles per hour. It was even faster when they were chasing their prey down for food.

Researchers discovered it by studying the footprints left behind by T-Rexes in ancient mud and sand. The researchers found footprints made with feet with three toes on each foot. The big surprise was that the middle toe was longer than the other two. The middle toe allowed them to move without losing their balance or leaning forward too much (like some other dinosaurs).

It makes sense when you consider how dangerous it would be for something like a T-Rex to run around without being able to move quickly enough. If it were slower than an average human, it would have been easy prey for other animals looking for lunch.” 

The T-Rex’s legs were long and muscular, which helped it reach speeds up to 45 miles per hour (72 kilometers per hour). Its top speed is slightly more than twice that of a human.

This dinosaur was well-adapted for running—it had very short forelimbs that allowed it to keep its balance while moving. The T-Rex also had wide feet with three toes instead of five, making it easier to move faster without tripping over itself.

The T-Rex’s ability to run so quickly is why scientists believe they hunted in packs. When one animal attacked an animal larger than itself, others would be able to catch up quickly enough to help finish off their prey.

The Largest Dinosaur Footprint Ever Discovered

Sixty-six million years ago, dinosaurs roamed the Earth. They were so big that they made massive footprints that we still find today. The largest dinosaur footprint ever found is 5 feet long and was likely made by a brachiosaurus.

After 20 years of excavating the Cleveland-Lloyd Dinosaur Quarry in Utah, paleontologist Matthew Mossbrucker uncovered a footprint from a prehistoric dinosaur. The footprint dates back to the Jurassic period, approximately 150 million years ago. The quarry has yielded thousands of dinosaur fossils since its discovery in the 1970s. Protected by the sand and mud, the print survived under layers of rock which protected it from weathering over time. 

The brachiosaurus lived during the Jurassic period and was one of the largest animals to ever walk on land with its huge body and long neck. It had four legs, each with three toes, which helped it walk across the ground.

The brachiosaurus had a small head with a small horn on top, which they used for protection from predators or mating rituals. Some scientists believe that this dinosaur could grow up to 40 feet long and weigh up to 80 tons.

Its name means “arm lizard” in Greek because of its long front legs that resembled arms more than legs. The brachiosaurus lived during the Jurassic period (200 million years ago). It was one of the largest animals to ever walk on land with its huge body and long neck. It had four legs, each with three toes, which helped it walk across the ground.

How Big Was the Brain of the Biggest Dinosaur?

That’s right—the most fearsome creatures to ever roam the Earth were only equipped with brains that were the size of walnuts. Dinosaurs had the brains of walnuts, but that wasn’t a bad thing. How did they survive?

The reason is that their brains were quite different from ours. Their brains had two lobes connected by a thick band of tissue called the corpus callosum. This structure allowed dinosaurs to process information more quickly than humans today.

This speed was that dinosaurs had faster neurons than humans do. The faster neuron functioned by sending a signal down one side of its cell membrane, then back up again before releasing neurotransmitters into the synapse. It only took about 20 milliseconds for this process to occur, whereas human neurons take about 50 milliseconds to fire off signals and release neurotransmitters into synapses.

Paleontologists have found that many dinosaurs had many neurons within their brains—more than most reptiles and birds. Dinosaurs’ brains got bigger as they got older, which mammals do not. It means that dinosaurs could grow smarter over time, which may explain why they were so successful during the Mesozoic Era (252-65 million years ago).

Dinosaurs were intelligent creatures, even though their brains were quite small. They had complex social structures and could communicate with each other through vocalizations. Some of them even had their languages. Dinosaurs were much more intelligent than we give them credit for, but it’s hard to say because we don’t know enough about their brains or what they were capable of thinking.

Birds are the Modern-Day Forms of Dinosaurs: Here’s How

We can all agree that dinosaurs were pretty amazing—and they were super cool. But what if we told you: that all birds are direct descendants of dinosaurs? That’s right—your birdy friend is a dinosaur! If you ever wanted to know what a dinosaur looked like, look at your bird. 

Birds have tiny little arms and two legs. They also have feathers and beaks, and both birds and dinosaurs lay eggs. And these features are all the same as those of their prehistoric ancestors.

Birds don’t look like dinosaurs any more than you look like your great-great-grandparents—but they still share a common ancestor. All mammals (including humans) descended from reptiles that lived more than 350 million years ago.

Birds are the only living things classified as dinosaurs, but they are not the only animals with a common ancestor. Reptiles, mammals, and amphibians evolved from the same group of reptilian creatures known as archosaurs. These archosaurs gave rise to crocodilians and birds, while other archosaurs evolved into lizards, snakes, and turtles. 

Check out these other animals in the Dinosauria order if you love dinosaurs. That’s right: birds are living dinosaurs! Why do so many people think dinosaurs are extinct? The answer is simple: they aren’t. Birds are alive and well all over the planet today, including in your backyard.

Dinosaurs had Bullet-Proof Vests Made of Bone

Dinosaurs had armor! It’s true! But not all of them—just those who lived in warm climates. The rest were more like naked dinosaurs. There was one type of dinosaur called the ankylosaur, and it had a knight’s suit of armor made out of bone and looked like a bullet-proof vest for a dinosaur.

They had thick hides made of bony plates called osteoderms that protected their bodies from bites and scratches. They swung their clubbed tails around at other dinosaurs during fights over territory or mating rights.

The dinosaur bones form a protective shell that protects them from harm. When the animals grew, their cartilage strengthened the places where their bones connected. It made it possible for the dinosaur to move without fear of getting hurt.

Dinosaurs also used armor to show off their strength and beauty. Some dinosaurs had their unique designs. Some had spikes or spines along their backsides. These features could help protect them from predators or provide them with an advantage when hunting for food.

Ankylosaurs were huge, like rhinoceroses—they could weigh up to 8 tons. That’s almost as heavy as two elephants put together. They had so much weight because they lived in warm climates and didn’t need very much muscle to move around or fight off predators because there weren’t many predators around that could eat an ankylosaur.

Humans Evolved from Dinosaurs

It’s a question plaguing scientists for decades. Human beings are the products of evolution, which means they evolved from other species. Humans didn’t evolve from monkeys. Dinosaurs didn’t become birds. And we’re not going to let you believe that humans evolved from apes.

Here’s the real story: Humans and dinosaurs are both descendants of prehistoric reptiles, which themselves evolved from amphibians. The Earth formed with a significant amount of water frozen on its surface, and this ice receded over time to form oceans. Amphibians were the first reptiles to evolve at this time because they were able to adapt to a marine lifestyle.

The earliest known prehistoric reptiles looked very similar to modern crocodiles, but over time their bodies changed dramatically as they adapted to life at sea. Those closest to the equator grew larger than those who lived further north or south. Today, you can see crocodiles in the tropics but not in the Arctic.

These marine reptiles started developing lungs instead of gills to move onto land and swim in water; some even developed legs instead of fins. People of ancient times used to call these “sea monsters” because they did not look like anything alive today. They were early versions of dinosaurs such as ichthyosaurs and plesiosaurs (“near-sighted lizard”).

That’s a fact, and it’s something that most people in the scientific community agree on. But it’s also something that many people outside the scientific community don’t understand—and that can lead to some pretty serious misconceptions about what science has to say about our origins. Humans are not the only species that evolved from dinosaurs. We’re just one of many.

Conclusion: Dinosaurs Still have Many Things to Teach Us!

Dinosaurs have been extinct for millions of years, but they still have many things to teach us. We can learn a lot from how they lived, how they died out, and how they were once the dominant species.

The fascination that children and adults feel for dinosaurs has given rise to several myths and legends about them. Dinosaurs are often used as metaphors in literature. Writers use them as symbols of power or strength, or they might use them to describe the forces of nature like storms or earthquakes.

Even though they lived so long ago, dinosaurs are still often used as metaphors in literature. The term “cold-blooded” means that someone does not care about other people’s feelings but only thinks about themselves. That’s like some dinosaurs, very large reptiles with no feathers and can’t regulate their body temperature. 

Dinosaurs also help us understand ecology—the science of living things and their interactions with one another and the environment. Dinosaurs are amazing creatures, and they have helped us understand our world today better than ever before. We need to continue learning about these amazing creatures because there is still much more to discover!
