  • Turkana BoyIconic fossil

    Turkana Boy

    Homo erectus · KNM-WT 15000

    Found in 1984 by Kamoya Kimeu

    Nariokotome, Lake Turkana

    Museum: National Museums of Kenya, Nairobi

    The most complete Homo erectus skeleton ever found: a boy aged between 7 and 11 who lived 1.5 to 1.6 million years ago. His long legs and build show how far adaptation to walking on two legs had already progressed.

  1. Eon4,567 – 4,031 Ma

    Hadean

    536 million years

    Formation of the Earth; a magma ocean, the impact that formed the Moon, and the first solid crust.

  2. Eon4,031 – 2,500 Ma

    Archean

    1,531 million years

    The first continental cores (cratons) and the first life.

  3. Eon2,500 – 720 Ma

    Proterozoic before the Cryogenian

    1,780 million years

    Increasing oxygen levels, more complex life, and the formation and breakup of supercontinents.

  4. Period720 – 635 Ma

    Cryogenian

    85 million years

    ‘Snowball Earth’: ice sheets reached the equator following the breakup of Rodinia.

  5. Period635 – 538.8 Ma

    Ediacaran

    96.2 million years

    Complex multicellular organisms appeared after the major glaciations.

  6. Era538.8 – 298.9 Ma

    Paleozoic before the Permian

    239.9 million years

    Animal life diversified; plants and animals colonized the land.

  7. Period298.9 – 251.9 Ma

    Permian

    47 million years

    Pangaea was fully assembled; the period ended with the largest mass extinction in Earth's history.

  8. Period251.9 – 201.4 Ma

    Triassic

    50.5 million years

    Pangaea began to break apart, and the first dinosaurs appeared.

  9. Period201.4 – 145 Ma

    Jurassic

    56.4 million years

    Laurasia and Gondwana became increasingly separated.

  10. Period145 – 66 Ma

    Cretaceous

    79 million years

    The Atlantic Ocean widened; the period ended with a mass extinction.

  11. Period66 – 23.03 Ma

    Paleogene

    43 million years

    Mammals diversified, and the continents moved closer to their present positions.

  12. Period23.03 – 2.58 Ma

    Neogene

    20.5 million years

    Grasslands expanded and early hominins appeared.

  13. Period2.58 Ma – present

    Quaternary

    2.6 million years

    Ice ages and the emergence of modern humans.
