The Best Earth´s Timeline Ever

  • Period: 4600 BCE to 560 BCE

    Precambriam

    Guide Fossil: Estromatolites

  • Origin Of Life
    3800 BCE

    Origin Of Life

    The origin of life was a long process called abiogenesis. Abiogenesis occurred through chemical evolution, one of them are the Cyanobacterias who were the first organism that produced oxygen.
  • Period: 560 BCE to 250 BCE

    Paleozoic

    Guide Fossil: Trilobites

  • First Arthropods

    First Arthropods

    They were the first animals to develop a rigid chitinous exoskeleton, the most famous is the trilobite
  • Start Of The Fishes Era
    500 BCE

    Start Of The Fishes Era

    Fishes were the first animals to have a backbone
  • First Land Plants
    420 BCE

    First Land Plants

    Known as bryophytes they were one of the first land plants. They reproduced via spores and required water for the male gametes (sperm) to swim to the female gametes
  • First Bony Fishes
    370 BCE

    First Bony Fishes

    The development of a true internal bony skeleton and jaws gave them a huge advantage, leading to their dominance.
  • First Reptils
    315 BCE

    First Reptils

    They were small, lizard-like animal, measuring about 20 to 30 centimeters, including the tail
  • Pangaea Formation
    280 BCE

    Pangaea Formation

    Pangaea was the result of plate tectonics, a gradual process of collision and fusion of continental masses.
  • The Great Dying
    250 BCE

    The Great Dying

    The Great Dying, known as the Permian–Triassic extinction event, occurred approximately 250 million years ago and it is the biggest extinction in Earth's history. It wiped out an estimated 90% to 96% of marine species
  • Period: 250 BCE to 66 BCE

    Mesozoic

    Guide Fossil: Ammonites
    Geological Events: Pangea Fracture
    Climate Events: Greenhouse Event
  • Golden Age of Dinosaurs
    208 BCE

    Golden Age of Dinosaurs

    With their rivals gone from the Triassic extinction, dinosaurs became the undisputed dominant land animals.
  • First Mammals
    200 BCE

    First Mammals

    Early mammals were generally small creatures, about the size of a mouse or shrew, and are believed to have been primarily nocturnal to avoid the large dinosaurs.
  • Period: 66 BCE to 1 BCE

    Cenozoic

    Guide Fossil: Mammals
    Geological Events: Orogens
    Climate Events: Rising Oxigen
  • First Primates
    65 BCE

    First Primates

    The first primates and their precursors emerged
    approximately 66 to 55 million years ago, following the mass extinction of the dinosaurs.
  • First Megalodons
    23 BCE

    First Megalodons

    They reigned as the ocean's apex predators for over 16 million years before becoming extinct roughly 3.6 million years ago.
  • Tools Use
    3 BCE

    Tools Use

    Hominins like Australopithecus afarensis, the species of the famous "Lucy" fossil were likely the first tool users.
