    During the Cambrian period there was fragmentation of Rodinia (Pangaea I). In this period,
  • Period: 541 BCE to 505 BCE

    paleozoic era

    The Phanerzoic began with the explosion of life of the Cambrian period. Phanerzoic means "visible life". Large coastal areas with favorable climates appeared that favored the appearance of almost all groups of animals and vegetables of the Cambrian.

    event of the Silurian Period.

    event of the Silurian Period.
    In the Silurian Period begins the conquest of the emerging lands. Vascular plants (Pteridophytes) and terrestrial arthropods manage to colonize the mainland, being able to leave. Due to the explosion of plant life and the conquest of the earth, the atmosphere reaches a 21% of O2, as at present.. The first vertebrates appear, which are fish 21% of O2, as at present.. The first vertebrates appear, which are fish.

    In the Triassic, Pangaea begins to fragment into the continents we know in the today.. Different groups of animals, such as dinosaurs, appeared (230 m.a.), ammonoids (225 m.a.) and pterosaurs (205 m.a.)

    Permian Period.

    Permian Period.
    The supercontent Pangea was formed which, together with the great volcanic activity that occurred in the Permian, greatly increased the greenhouse effect.
    La formación de Pangea provocó la orogenia hercínica, que formó muchas cadenas montañosas.

    event of the Permian Period.

    event of the Permian Period.
    The supercontent Pangea was formed which, together with the great volcanic activity that occurred in the Permian, greatly increased the greenhouse effect.
    The formation of Pangaea caused the Hercinic orogeny, which formed many mountain ranges.
  • Period: 245 BCE to 208 BCE

    Triassic period.

  • Period: 245 BCE to 65 BCE

    Mesozoic era

    When eating from the Mesozoic Era, the climate was extremely arid, but when the fragmentation of Pangea occurred it changed to a humid tropical climate. There was a warm, glaciated climate in this Age.

  • Period: 65 to 21

    Cenozoic era

    The continents that had fragmented from Pangaea continued their separation to their present position.
    When the fragmented continents of Pangaea collided, mountain ranges such as the Alps, Pyrenees and Himalayas formed. Alpine orogeny developed.
    The Atlantic Ocean continues to expand.
