First the facts. Dinos all live in the Mezosoic era in three different time periods. The Triassic, Jurrasic and Cretacous were the three time periods.
Buckle your seat belts because were going on a journey back in time to the Triassic period. It lasted from 251-200 MYA (million years ago). Here was where the dinosaurs were about to be roaming. This is Pangea the super continent. You may have heard of it before or not.
Here on this map all of the countries can be seen. The first dino lived here and it was a small raptor called Eoraptor.
As time passed on these Carnivores and Herbivores evolved and became bigger, four-legged sauropods and stronger theropods. There were also defense mechanisms on some herbivores to increase the rate of survival.
We are now in the Jurrasic period and it lasted from 200-145.5 MYA ago. Here is where the first birds came. Archeopteryx was a dino-bird. Even though ‘dinosaur’ means ‘terrible lizard' in Latin the closest relative to a dinosaur is a bird. Pangea was also splitting apart into Laurasia and Gondwana and the sea between them was called the Tethys sea.
Then came the Cretacous period and everything was the same. The countries were taking shape and forming to their normal state. The Cretacous lasted from 145.5-65.5 MYA.
Then came the end of the dinosaurs. Some people say it was because of an asteroid crash. Some people say it was because of a volcanic eruption.
Some people say it was both. All that was left of them were their bones. Here are some fun facts:
Other creatures lived alongside the dinosaurs called pterosaurs, mosasaurs and plesiosaurs. Pterosaurs were flying reptiles and Mosasaurs and Plesiosaurs were sea creatures.
- Icthyornis was the first sea bird. It looked exactly like a bird but with sharp teeth.
- Some dino fossils were baby dinos but paleontologists thought they were other dinos! For example a baby triceratops was used to be thought as a Torosaurus.
Here is one story about a Baby Triceratops named Zoe:
One sunny day, a little triceratops named Zoe was waddling around a lush, green forest with her friends. There were lots of lovely things to see like the beautiful daffodils and prehistoric ferns. It was Spring and Zoe and the three friends breathed in the fresh air. “WOW!” Amanda, the baby Parasaurolophus, Zoe’s friend, said. In front of them was a gushing waterfall. They stopped to sip the fresh water and started relaxing. After that, they wanted to play although it was getting late hence they strolled sleepily back home.
They continued to wander along the forest in wonder of where to go. It was official that they were lost. Or were they? Everybody could see a little light far away from them. They followed the little light and it grew bigger and bigger until they reached it. It was actually a bonfire at their home. Their mothers rushed to them and asked worriedly, “Where have you been?” ”It’s a long story.” they all said.
