HISTORY OF THE EARTH

By Luciana.ees
  • Period: 4500 BCE to 520 BCE

    PRECAMBIAN

    Guide fossil: Stromatotites
    Geological event: 0% atmosphera oxigen, First ocean and Formation first continent
    Climate events: First glaciation
  • First Life (Luca)
    4000 BCE

    First Life (Luca)

    Prokaryotes, bacteria, archaea, methanogens
  • Period: 520 BCE to 220 BCE

    PALEAEOZOIC

    Guide fossil: Trilobites
    Geological event: Pangea and volcanic activity
    Climate events: global warming
  • First plants reefs (cyanobacteria)
    470 BCE

    First plants reefs (cyanobacteria)

    They invented the fotosinte oxygenic photosynthesis, freedom huge amounts of oxigen to the atmosphera, this became the Earth and allowed the evolution of complex life.
  • eurypterids
    460 BCE

    eurypterids

    known as "sea scorpions," were huge, armored arthropods from the Paleozoic era.
  • First mass extincion
    443 BCE

    First mass extincion

    This extintion eliminaed the 85 % of the marine species.
    Made this the second largest extinction in Earth's history. caused by an glaciation
  • Crinoids
    430 BCE

    Crinoids

    Crinoids (or sea lilies) are marine echinoderms similar to starfish or sea urchins, known for their plant-like appearance with flowers.
  • First Vertebraste
    420 BCE

    First Vertebraste

    The firts vertebrates were the fish without jaw (agnathous)
  • Age of fish
    375 BCE

    Age of fish

  • Second mass extinction
    370 BCE

    Second mass extinction

    It was a series of events caused by a combination of factors, such as the lack of oxygen in the sea caused by the development of terrestrial plants or a possible sudden global cooling, affecting mainly marine life, but also terrestrial life.
  • Age of amphibians
    365 BCE

    Age of amphibians

  • First insects
    350 BCE

    First insects

  • First forest
    350 BCE

    First forest

    They played a crucial role in oxygenating the atmosphere and stabilizing the soil.
  • Age of reptiles
    315 BCE

    Age of reptiles

  • Third mass extinction (the longest)
    252 BCE

    Third mass extinction (the longest)

    It was caused primarily by enormous volcanic eruptions, which released CO2, causing extreme global warming, and the release of toxic gases, completely destabilizing terrestrial and marine ecosystems and eliminating up to 96% of marine life and much of terrestrial life.
  • Period: 220 BCE to 67 BCE

    MESOZOIC

    Guide fossil: Ammonites
    Geological event: Pnagea (break up) and the possible impact of a meteorite
    Climate events: Green house event and warm weather
  • fourth mass extinction
    201 BCE

    fourth mass extinction

    This mass extinction was mainly caused by gigantic volcanic eruptions, which released greenhouse gases and sulfur, causing extreme climate changes (global warming followed by intense cold) and leading to the death of many reptiles and amphibians.
  • Age of the birds
    150 BCE

    Age of the birds

  • fifth mass extinction
    66 BCE

    fifth mass extinction

    It was caused primarily by the impact of an asteroid, which triggered a global catastrophe with tsunamis, fires, and dust being thrown up, extinguishing the dinosaurs and about 75% of species.
  • Period: 66 BCE to 1 CE

    CENOZOIC

    Guide fossil: Nummulites
    Geological event: continental drift and the mountain formation, savanna and glaciers
    Climate events: The ice age
  • Age of mammals
    65 BCE

    Age of mammals

  • First primates
    40 BCE

    First primates

  • Terror birds
    13 BCE

    Terror birds

  • First hominids
    8 BCE

    First hominids

  • First Homo sapiens
    2 BCE
