How to write about dinosaur lulu after reading

Dinosaurs were the biggest animals in the world, but they are extinct. They had huge bodies, but they walked very fast. There are two kinds of dinosaurs: one is herbivorous and the other is carnivorous. The herbivorous dinosaurs were most afraid of the carnivorous dinosaurs because the carnivorous dinosaurs would have hunted down the herbivores to feed on them. Carnivorous dinosaurs usually walked on two legs and had two other legs that didn't hit the ground. Carnivorous dinosaurs were smaller compared to herbivorous dinosaurs, but they were still stronger. For the extinction of the dinosaurs, scientists have all sorts of ideas: some think it has something to do with the asteroid collision, some think it has something to do with the volcanic eruption, and some think it has something to do with the climate change. If there are still dinosaurs, it would be good, we can not only see the dinosaurs, but also to study it properly! Scientists wouldn't have to argue about it.
