Dinosaurs are wonderful, mysterious creatures who lived millions of years ago. These periods of time are known as Triassic, Jurassic, and Cretaceous. I believe the more we learn about these creatures, the more we know about how they lived and what our world was like back then and how it effects us today. One of the things we learned from them was about how our climate was back then. The dinosaurs had more CO2 in their atmosphere which helped the plants grow bigger and better than today's plants.Though we wouldn't be able to survive in that environment that contained high amounts of CO2.

Before the continents were separated,They were all together and formed a super continent called Pangaea. All of the continents were together until the asteroid wiped out all life on earth but the human and rat size mammals and reptiles went under ground and sadly the larger dinosaurs died out forever on earth. Today the ancestors of the meat-eating theropods can be found just look at the eagles, hawks, falcons, vultures, owls, and hunting birds. We know from the fossils what they ate, where they were from, what there species were, and what period the species was from. As we continue to dig we will learn more and more of what the world will come to be.
