Today for Science we were learning about Dinosaurs. The three period of times are Cretaceous, Jurassic, Triassic.

Cretaceous - Cretaceous is a geological period from about 145 to 66 million years ago.Cretaceous is the third and final period of the Mesozoic Era.

Jurassic - Jurassic is a geological and system that spanned 56 million years ago. The Jurassic constitutes the middle period of Mesozoic Era.

Triassic - (252-201 Million years ago) The Triassic Period stared after the earth's worst ever extinction. It took place 252 million years ago ad was the most significant events in the history of our planet.
