Dinosaurs lived about 250 million years ago until about 50 million years ago. At that time, the continents were not yet driven apart like at this moment. Instead, there was a large continent called Pangea. Around 50 million years ago dinosaurs died quite suddenly due to a huge meteorite impact. Some animals related to the dinosaurs are still alive. Well known are the crocodilians and the birds. There were many thousands of different species of dinosaurs, from small to large and both herbivores and meat eaters.
Dinosaurs are reptiles which means they laid eggs, from which the small dinosaurs were born. Because no one has ever seen the animals in real live, research of fossils and bones of dinosaurs is being done to find out how they looked like. Famous are the large dinosaurs that could be up to 11 meters high and 30 meters long. But there were also very small dinosaurs not bigger than a few centimeters.
Well-known dinosaurs are:
The stegosaurus, this was a plant eater and he is known for the large plates on his back and the deadly spines on his tail. With his tail he could hold off enemies.
Another known plant eater is the triceratops, which is known for its three horns with which he defended himself. A triceratops weighted 3,000 kilograms.
Perhaps the most famous dinosaur is the tyrannosaurus (T-rex). This was a dangerous meat eater with large and sharp teeth. A tyrannosaurus weighted 6,500 kilograms and was about 12 meters long and 5 meters high.
The velociraptor was a smaller but quicker hunter. This dinosaur hunted in a group so that they could overpower large prey. It is suspected that this dinosaur also had feathers.
The archaeopteryx is a flying dinosaur and is also called the primeval bird. This dinosaur is probably the first bird that ever existed. He had a long, bony tail and a pointed snout. In addition, he had claws to grab his prey well.
