Dinosaurs. Dinosaurs are ancient reptiles that lived between 239-70 million years ago in a long,long,long, time age called the mesozoic. Some dinosaurs were long like diplodocus and argentinosaurus. The largest dino I know is the argentinosaurus he is also the heiviest dinosaur! He is 125 tons and 155 feet long! The smallest dino was microraptor. Microraptor was 19.5 inches long and 1.7 pounds! But a tragic day came 70 million years ago when somthing probably killed off the dinosaurs! It killed off the plants, then the plant-eating dinosaurs, then the meat-eating dinos such as the large tyrannosaur appalachiosaurus! But 70 million years later we can find the same appalachiosaurus in the rock and sand then he will be mounted in a museum. Then the appalachiosaurus will be studyed and stared at for a very,very,very long time.
