The dinosaurs did exist, yes!
How Do We Know?
Well, archaeologists have found loads of fossils and skeletons to prove it. In lucky cases, the dinosaur bones are still in the position that the creature died in, which is how we know what they looked like.

Dinosaurs Through the Ages
- The theory is that the dinosaurs first appeared during the Triassic Period, which was around 230 million years ago. One of the first dinosaurs was the coelophysis, which was a small, light-framed biped that ate meat.
- The Jurassic Period, which began about 200 million years ago, is when the dinosaurs were at the top of the food chain – not only were they the most powerful creatures around, but there were also loads of them. The diplodocus and stegosaurus lived during the Jurassic Period, but despite popular belief, the T-Rex didn’t come until later!
- After the Jurassic Period came the Cretaceous Period. This period began around 145 million years ago, and it was at this time that you’d find the T-Rex and triceratops.
- The Paleogene Period came 65 million years ago. The beginning of this period is marked with the extinction event that wiped out the dinosaurs.
- The most popular explanation for the dinosaurs’ extinction is that a meteor hit Earth. There’s a huge crater beneath Mexico which suggests that the meteor was 110 miles wide – if it didn’t squash all the dinosaurs, the theory is that it caused a dramatic climate change that caused them to become extinct.
