When the dinosaurs first appeared there was one big continent called Pangea. Later in when the dinosaurs got more dangerous the continent was breaking apart.
These are dinosaurs that were carnivores changing over the years.
The dinosaur from picture 1 is a Coelophysis from the triassic period. It was 10 feet long. The one from picture 2 is an Allosaurus. It came from the jurassic period. It was 30 feet long. The one from picture 3 is a Giganotosaurus. It came from the cretaceous period. It is 45 feet long.

When dinosaurs ruled the earth the earth was the most dangerous it got ever. There were still monsters in the sea. In this time the biggest animals lived, the most dangerous sea and the biggest meat eater giants on land.
Here are sea monsters that lived at the time of the dinosaurs. The order of the pictures show which ones were first and then changing.
The one from picture one is a Thalattoarchon, It came from the Triassic sea, It was 28 feet long. In picture 2 is a Pliosaurus, it came from the Jurassic sea, it was 40 feet long. The one in picture 3 is a Tylosaurus, it lived in the cretaceous period, it was 40 feet long. The sea it lived in was the Western Interior Sea which was the most dangerous sea ever.

Then the dinosaurs time came to an end. A giant meteor came and hit earth. Then a million little pieces of the meteor that could do the same damage as an atomic bomb flew all over the earth and hit the earth. Months without sunlight was very bad. The food chain was cut. No plants could survive in this condition so then herbivores died then. And when all the the meat was eaten by the carnivores. The carnivores started to die. But size mattered. The smaller the animal the less food it needed. The mammals in the dinosaur age were small. This all happened because of one meteor. After without sunlight mammals and birds took over the world.
