Bio-Geo Timeline

In class we worked on a project in class and we were assigned a certain time period. My partner Phil and I were given the Jurassic time period. This time period lasted from about 200 million years ago to 140 million years ago. This time period was the peak of the dinosaur era. There was also a large variation of plants. Since there was 20 percent oxygen in the atmosphere most of the organisms that existed back then grew to very large sizes. Also the landscape of the earth was different back then. Instead of having the seven individual continents like we do today, there was only one major continent called Pangaea. Although there was one big continent there was a little separation between what is now South America and Africa. The Jurassic Period was the height of the dinosaur era and I learned a lot about it by doing this assignment.
