The History of Dinosaurs
by Ana Laura
(São Paulo,SP, Brazil)
Dinosaurs were extinct 65 million years ago, and to my mind, our planet Earth was really hit by an asteroid.
However, our planet didn't explode, moreover, 30% of those animals which had lived at that time stayed alive, some of them have been living so far, such as cockroaches, lizards and geckos.
Furthermore, the dinosaurs were cold - blooded, so if the temperature was too cold the dinosaurs would die because their flesh was to thin and they didn't have fur to warm them up.
Throughout that period, many of the animals that used to live became extinct.
So in conclusion, I hope you liked it and I thank you all for your attention.
