world of dinosaurs

I'm going to tell you about the world of dinosaurs.



Dinosaurs were animals that lived a long long time ago before people lived on Earth. Dinosaurs ate meat called carnivores and some ate plants called herbivores and also omnivores dinosaurs that both meat and plants. They also have horns, crests, spikes, thrills and feathers. The world has 3 periods called Triassic, Jurassic and Cretaceous. The first period is called Triassic Period 248 to 206 million years ago. During the Triassic Period the continents were mast together forming one giant continent called Pangaea. It has flies, bees and wasps appeared during the Triassic Period.





 The second period is called Jurassic Period 206 to 144 million years ago. During the Jurassic Period the land mase of Pangaea drifted apart into 2 continents called Gondwanaland and Laurasia. The oceans of the world during the Jurassic Period were full of creatures such as shellfish fish and huge marine reptiles. The third period is called Cretaceous Period 144 to 65 minion years ago. During the Cretaceous Period the continents of Gondwanaland and Laurasia drifted further part into small land masses. The continents almost like do today. The oldest known ants and butterflies appeared during the Cretaceous Period.



Paleontologist the scientist to study prehistoric life and they use fossils as clues to figure out much as they can about dinosaurs. Fossils are a kind of diary of the past. They tell a life on Earth long ago. Coelophysis is one of the earliest dinosaur built for speed against predators. Scientists think Coelophysis lived in large family groups possibly herds
