2 According to the Cosmic Calendar, when was our Solar system born?

4 When did Photosynthesis start?

The reptiles were members of a subclass of other big reptiles known as the archosaurs, which existed during the middle to late Triassic period. This happened some 230 million years ago. During the early Jurassic period, these animals experienced significant changes when the world started to break down into the continent, which affected their existence. As a result, the dinosaurs disappeared mysteriously around 65 million years ago during the cretaceous era.
9. When did the dinosaurs get extinct?
The emergence of dinosaurs happened when the world was still intact, which is also known as the Pangea. However, during the Jurassic period, when the world started to break into continents, the animals were greatl...
