Geologic-Biologic Timeline

The class spent a week and a half doing a project regarding the prehistoric eras of the Earth, starting from the Cambrian period, to Tertiary.  We were split into groups and had to research one of these periods.  My group was Tertiary.  I learned that the Tertiary was mostly what the Earth looks like today; the mammals were diversifying, Pangaea was splitting to make the continents known now, and halfway through there was a worldwide ice age.  This all happened between 2 to 65 million years ago, after all the dinosaurs died.  I worked well with my one partner in this project.  We looked through the books we could find, jotted down information we thought was important, and wasted no time trying to make it all look good.  The other groups in the class also did well with presenting the things they found.  The Triassic period had many forests, and saw the first turtles.
