Abstract
The Mesozoic Era “the middle life” is the second major Era that lies between the Paleozoic Era and the Cenozoic Era. Geologist believe that this Era took place from 248 to 65 million years ago. The earth during this time was different from what we know today. The shape of the earth and life during this time period has changed dramatically. Starting with an overview of the Mesozoic Era and its subdivisions periods I will focus on major events during those time periods that took place in the western side of the North America, which made this time period so significant in the earth history. Each period of the Mesozoic Era was marked for certain events that makes it especial from other periods. During the Triassic period extensive Red Beds deposits along western interior of North America that made the beauty of the landscape in that region. Major tectonic activities occurred starting from the Triassic period and expanding throughout …show more content…
