When Dinosaurs Ruled the Earth Banner
The dinosaurs ruled the earth for millions of years. They were the largest and most powerful creatures that ever lived. But they all died out about 65 million years ago. How could such powerful creatures just disappear? Scientists have many theories about what happened to them, but no one knows for sure.

Dinosaurs ruled the earth for millions of years, and their legacy can still be seen all around us. Even though they are no longer with us, their impact on the world is still very evident. One of the most obvious ways that we can see this is through the fossil record.
Every time a new dinosaur fossil is found, it provides us with another piece of the puzzle that helps us to understand these amazing creatures. But fossils are not the only way that dinosaurs have left their mark on our world. Their size and power also meant that they had a huge impact on the environment around them.
For example, it is thought that dinosaurs helped to shape many of today’s landscapes by eating plants and shaping the land as they moved around. So even though dinosaurs are no longer with us, their influence is still very much felt in our world today. And every time we learn more about them, we get just a little bit closer to understanding how these incredible creatures once ruled our planet.
When Dinosaurs Ruled the Earth Banner Printable
When dinosaurs ruled the earth, they were the largest and most feared creatures around. But now, they’re just big lizards that people dress up in costumes and use for entertainment. How did this happen?
Well, it all started with a few bones. In 1822, Mary Ann Mantell discovered some fossilized teeth while walking along a road in England. Her husband, Dr. Gideon Mantell, realized that these teeth belonged to an extinct creature and began collecting more fossils.
Other scientists soon began finding dinosaur bones as well, and by the mid-1800s, there was enough evidence to start piecing together what these creatures might have looked like. The first dinosaurs were actually quite small— about the size of a chicken— but as more fossils were found, it became clear that some of them had been massive! The biggest dinosaur ever found is called Argentinosaurus huinculensis— it was probably over 100 feet long and weighed over 100 tons!
As scientists learned more about dinosaurs, they also realized that these creatures must have gone extinct at some point. There are several theories about why this happened, but the most likely cause is a comet or asteroid hitting the earth 65 million years ago. This event caused widespread devastation and killed off all of the dinosaurs (and many other animals).
But even though they’re no longer alive, dinosaurs continue to fascinate us. People love to learn about these creatures and imagine what it would have been like to see them alive. And every once in awhile, we get lucky enough to see them come back to life on screen!

When Did Dinosaurs First Appear on Earth
Dinosaurs first appeared on Earth during the Triassic period, between 243 and 233.23 million years ago. The exact origin of dinosaurs is still unknown, but they are thought to have evolved from a group of archosaurians, which includes crocodiles and birds. Dinosaurs were the dominant terrestrial vertebrates for 135 million years, from the beginning of the Triassic period until the end of the Cretaceous period.
During this time, they diversified into millions of different species that occupied every possible niche on Earth.
How Long Did They Rule the Planet
They ruled the planet for approximately 3.8 billion years, from the time they first appeared until they went extinct.
What were the Biggest And Most Ferocious Dinosaurs
The Tyrannosaurus rex was one of the largest and most ferocious dinosaurs that ever lived. It was a massive creature, measuring up to 40 feet in length and weighing up to 20,000 pounds. This massive predator had a huge head with powerful jaws lined with sharp teeth, and it could run up to speeds of 25 miles per hour.
The T. rex was the king of the dinosaurs, and it ruled over the other dinosaurs with an iron fist. Another large and ferocious dinosaur was the Spinosaurus. This massive beast measured up to 50 feet in length and weighed as much as 30 tons.
It had a long neck and a huge sail-like back fin which made it look even more imposing. This carnivore also had sharp teeth and claws which it used to hunt down its prey. The Spinosaurus was an apex predator, meaning that it was at the top of the food chain; no other dinosaur could match its size or ferocity.
These are just two examples of some of the biggest and most ferocious dinosaurs that ever lived. There were many others, such as the Giganotosaurus, Carcharodontosaurus, Mapusaurus, and Carnotaurus; each one more terrifying than the last!
What Caused Their Extinction
The dinosaurs were a hugely successful group of animals that ruled the Earth for around 150 million years. But, 65 million years ago, they suddenly disappeared. So what caused their extinction?
There are many theories about what killed the dinosaurs, but the most popular one is that a comet, asteroid or meteor hit the Earth, causing all sorts of devastation and changing the climate so much that the dinosaurs couldn’t survive. Another theory is that there was a massive volcanic eruption at around the same time which also contributed to their demise. Whatever the cause, it’s clear that something happened to make conditions on Earth unsuitable for dinosaurs.
And while we may never know exactly what happened, it’s an event that has had a profound impact on our planet – and its inhabitants – ever since.
Conclusion
When dinosaurs ruled the earth banner, it was a time of great change. The world was a different place then, with new species appearing and disappearing. But one thing remained the same: the importance of banners in communication.
Banners were used by dinosaurs to communicate with each other and share important information. They were also used to warn others of danger or to claim territory. In some cases, banners were even used as weapons!
Despite their simple appearance, banners played a vital role in the lives of dinosaurs. They helped them stay safe, find mates, and navigate their changing world.
