    Quaternary Period- 2 MYA - Today

    Ice ages occured, as well as the presence of humans. Animals began to change into what they are today. Humans became a higher powered race, and advanced incredibly fast withing the thousands of years we've been here.
  • Tertiary Period- 65 - 2 MYA
    65

    Tertiary Period- 65 - 2 MYA

    The continents were getting closer to the formations they have today. Mammals and birds we're very large in size, and most look familiar while others have interesting shapes.
  • Cretaceous Period- 145 - 65 MYA
    144

    Cretaceous Period- 145 - 65 MYA

    This period is known for the asteroid that wiped out the a large percentage of all types of dinosaurs. Mammals started getting more complex, and plant life evolved.
  • Jurassic Period- 199 - 145 MYA

    Pangea began splitting apart. Dinosaurs we're becoming more complex, and large, and small mammals appear.
  • Triassic Period- 251 - 199 MYA
    251

    Triassic Period- 251 - 199 MYA

    Life on land was more populated than life in the water. Dinosaurs were starting to dominate the earth.
  • Permian Period- 298 - 251 MYA
    298

    Permian Period- 298 - 251 MYA

    During this time, the largest mass extinction in history occurred. The Supercontinent Pangea was forming, which caused severe weather and geologic issues.
  • Carboniferous Period- 358 - 229 MYA
    358

    Carboniferous Period- 358 - 229 MYA

    Massive swamp forests and plants were all over. Coal began to form in these forests do to the pressure of all the debris. Amphibian like creatures and giant bugs were on land.
  • Devonian Period- 416 - 358 MYA
    416

    Devonian Period- 416 - 358 MYA

    Plants were growing larger in size. Aquatic creatures were moving their way to more shallow waters and even land.
  • Silurian Period- 443 - 416 MYA
    443

    Silurian Period- 443 - 416 MYA

    Sea levels rise, and land climates become warm and stable. Plant life moves onto land, which were most likely lichen forming onto rocks.
  • Ordovician Period- 485 - 443 MYA
    485

    Ordovician Period- 485 - 443 MYA

    Most of the world was completely ocean, and a lot of the land had formed a supercontinent Gondwana. Life was becoming more advanced and dangerous.
  • Cambrian Period- 570 - 500 MYA
    570

    Cambrian Period- 570 - 500 MYA
