    First cells that produced oxygen

    First cells that produced oxygen
    Singular cellular organisms are being created and are producing oxygen which fills the atmosphere with breathable air which makes it livable for other organisms.
  • Period: 498 BCE to 1462

    Proterozoic

    The Proterozoic is a geological eon spanning the time from the appearance of oxygen in Earth's atmosphere to just before complex life on Earth. 2,500 million years old. The 3rd geological eon.
  • 280 BCE

    First Multi Cellular Organism

    First Multi Cellular Organism
    The First multicellular organisms were created 380 years after the single cellular organisms created oxygen.
  • Period: 1462 to

    Phanerozoic

    The Phanerozoic is the current geological eon that we are living in right now and the one where an abundance of life started showing up. It covers 541 million to present. It is also the 4th and last geological eon.
  • Period: 1462 to

    The Devonian period is the fourth geological period in the Paleozoic Era. The Devonian period spans 60 million years from the end of the Silurian period.

  • First Forest

    First Forest
    Underwater plants such as horsetails, Ferns, and Club mosses began to evolve and turned into a forest. Which at the time was known as the Earth's first forest.
  • Period: to

    Carboniferous

    The Carboniferous period is the fifth geological period in the Paleozoic Era. The Carboniferous period spans 60 million years from the end of the Devonian period.

  • First Mountains Created

    First Mountains Created
    Due to the continental shift that created Pangea the first mountains were created. Mountains are created when two continents hit each other and a gigantic piece of the Earth goes up creating a mountain.
  • Period: to

    The Permian period is the sixth and final geological period in the Paleozoic Era. The Permian spans 47 million years from the end of the Carboniferous.

  • Largest Mass Extinction

    Largest Mass Extinction
    The Largest mass extinction happened. It happened due to the new supercontinent formation called Pangea which introduced new extremes to weather such as volcanoes and tundras.
  • Period: to

    Mesozoic

    The Mesozoic Era is the 2nd of the three geological eras in the Phanerozoic Eon. It lasted from 252 to 66 million years.

    The Cenozoic Era is the 3rd and final Era in the phanerozoic Eon. It extends 66 million years from the Mesozoic Era.

  • Extinction of dinosaurs, Rising of the Mammals

    Extinction of dinosaurs, Rising of the Mammals
    This is the 2nd largest extinction wiping out all of the dinosaurs and opening a path for mammals to take over and grow

    Rise of the Homos!
    The earliest ancestor of humans called "Lucy" was found during this time. A great breakthrough.

  • Rise of the Humans!

    Rise of the Humans!
    Homosapiens begin as cavemen and start to dominate the planet and the mammals that ruled before.
