How Did Dinosaurs Go Extinct?
About 66 million years ago, a huge asteroid about 6 miles wide hit the Earth near the Yucatán Peninsula in Mexico. It might be what we did not hope for, this, causing earthquakes, wildfires, and giant tsunamis. Dust and debris filled the sky, blocking sunlight for months.
Without sunlight, plants died, and the animals that ate them starved. Most species disappeared one by one, including all non-avian dinosaurs. Scientists call this event the Cretaceous–Paleogene extinction event.
History of Dinosaurs for Kids
Dinosaurs lived on Earth for over 165 million years during the Mesozoic Era. This era has three main periods: the Triassic, Jurassic, and Cretaceous. Different types of dinosaurs evolved and adapted during each of these periods. Let’s take a look at how dinosaurs changed over time.
The Triassic Period (250 to 200 million years ago)
The journey of dinosaurs began in the Triassic Period, shortly after a mass extinction had wiped out most of the Earth’s life. During this time, all the continents were joined together in a giant landmass called Pangaea, and the world was hot and dry.
Early dinosaurs were small, fast, and two-legged. One of the first known dinosaurs was Eoraptor, a nimble predator the size of a dog.
Another early dinosaur was Herrerasaurus, which had sharp teeth and claws. Although they weren’t the biggest creatures yet, these early dinosaurs were fierce survivors who set the stage for what was to come.
By the end of the Triassic, dinosaurs began spreading to different parts of the world, gradually becoming larger and more diverse.
The Jurassic Period (200 to 145 million years ago)
Welcome to the golden age of dinosaurs! During the Jurassic Period, the Earth became more humid and filled with life. Ferns and tall conifer trees created forests that provided food and shelter. This allowed plant-eating dinosaurs to grow to enormous sizes.
This is when we meet some of the most famous dinosaurs, strengthen family bonds, and create memorable moments together.
-
Brachiosaurus, with its long neck and towering height, could reach food high in the trees.
-
Stegosaurus, known for its bony plates and spiky tail, roamed the forests munching on plants.
-
Allosaurus, a powerful meat-eater, was one of the top predators of this period.
The Jurassic period also saw the beginning of bird-like dinosaurs. Some small dinosaurs had feathers, hinting at the link between dinosaurs and modern birds.
The Cretaceous Period (145 to 66 million years ago)
The Cretaceous Period was the last chapter in the age of dinosaurs, and perhaps the most exciting. This period saw the greatest variety of dinosaur species, from armored tank-like creatures to fast-moving hunters and even feathered flyers.
Famous dinosaurs from this era include:
-
Tyrannosaurus rex, the king of the dinosaurs, is known for its massive jaws and tiny arms.
-
Triceratops is a three-horned plant-eater with a large frill protecting its neck.
-
Velociraptor was a smaller but clever predator that may have hunted in packs.
This was also the time when flowering plants appeared, along with buzzing bees and the early ancestors of modern mammals. It was a vibrant and evolving world.
But the Cretaceous Period ended in a catastrophe that changed the Earth forever.
How Do We Know Dinosaurs Existed?
We’ve never seen a live dinosaur, but we know a lot about them thanks to fossils—the preserved bones, teeth, footprints, and even eggs left behind in rocks.
What Are Fossils?
Fossils form when a dinosaur dies and its body is quickly buried under mud or sand. Over millions of years, the bones turn to stone. Paleontologists, scientists who study ancient life, dig up these fossils and study them to understand how dinosaurs lived, what they looked like, and how they moved.
Some fossil discoveries even include feathers, skin impressions, and fossilized stomach contents, giving us a more complete picture than ever before.
Are Birds Dinosaurs?
Yes! One of the most amazing scientific discoveries in recent decades is that birds are living dinosaurs, according to BirdLife International. They evolved from small, feathered meat-eaters like Velociraptor and Archaeopteryx.
The similarities we see in birds today, hollow bones, beaks, feathers, and even nesting behaviors, first appeared in their dinosaur ancestors.
So the next time you see a bird flying overhead, remember: you're looking at a tiny, modern dinosaur!
Conclusion
Dinosaurs weren’t just giant monsters; they were a diverse, complex group of animals that ruled the planet for millions of years. From the humble beginnings of Eoraptor in the Triassic to the mighty T. rex in the Cretaceous, dinosaurs evolved, adapted, and left behind an unforgettable legacy.
Thanks to fossils and science, we continue to learn amazing things about their lives, and even discover that they’re not entirely gone. Birds are living dinosaurs, and they remind us that the story of these ancient creatures isn’t over yet.
Frequently Asked Questions
What was the biggest dinosaur ever?
The Argentinosaurus, a plant-eater from South America, is believed to be the largest. It may have reached over 100 feet long!
Did all dinosaurs go extinct?
No! Birds are the direct descendants of certain dinosaurs, which means dinosaurs are still with us today.
How do we know dinosaurs had feathers?
Fossils found in China and other places have preserved feather impressions, showing that many dinosaurs were covered in feathers long before birds existed.
