    FIRST HOMO SAPIENS 23:59

    FIRST HOMO SAPIENS 23:59
    The oldest Homo sapiens fossils are almost 200,000 years old and come from southern Ethiopia (the Kibish Formation of the Omo River), considered the cradle of mankind (see Kibish Men). These fossil remains are followed in antiquity by those of Homo sapiens idaltu, about 160,000 years old.

    FIRST HOMINIDS 23:53

    FIRST HOMINIDS 23:53
    Scientific evidence indicates that hominids originated on the continent of Africa; the East African region is specifically indicated. Most hominin fossils, as well as the oldest ones, have been found throughout the African continent.
  • Period: 66 to AD 1

    CENOZOICO

    Guide fossil: Numulites.
    Geological events: Continental separation continues until the presents continents are formed, the formation of the Andes mountain range ends, the formation of the valley of Africa continues and Africa and India move north and the mountain ranges ofsouthern Europe emerges.
    Climate events: Ice age and the last great ice ages acurred.

    FIRST5 ANGIOSPERMS 23:22
    The first fossils of angiosperms come from the Secondary era, the lower Cretaceous, so it is inferred that they must have appeared in the Triassic or Jurassic. These are pollen grains similar to those of gymnosperms and the remains of whole leaves and parallelinervias.

    AGE OF THE BIRDS 23:39

    AGE OF THE BIRDS 23:39
    The evolution of birds probably began during the Jurassic period, from coelurosaurus dinosaurs, which among other things share with the ornithic fauna the presence of feathers on their bodies and related bone characteristics. Also according to current scientific consensus, birds , crocodiles and close relatives, represent the only living members of a clade known as Archosauria.

    FIRST DINOSAURS AND MAMMALS 22:44

    FIRST DINOSAURS AND MAMMALS 22:44
    The first mammals appeared at the end of the Triassic, a little over 200 million years ago, but they remained in the shadow of the dinosaurs until they disappeared during the Cretaceous-Tertiary mass extinction, about 66 million years ago.
  • Period: 245 to 66

    MESOZOICO

    Guide fossil: Ammonites.
    Geological events: Fracturation of Pangea and possible impact of a large meteorite.
    Climate events: Began a dry and warm trend during the Triassic.

    AGE OF THE REPTILES 22:43

    AGE OF THE REPTILES 22:43
    The first reptiles appear, such as the Ichthyostega. Basic reptiles such as the Cotylosaurus appeared more than 300 million years ago, in the late Carboniferous period of the Paleozoic era. During the next period, the Permian, they dominated the swamps and gave rise to the rest of the reptiles, including those that dominated the next era - the Mesozoic

    FIRST TERRESTRIAL PLANTS (GYMNOSPERMS) 21:48
    they are a group of seed-producing plants that includes conifers, cycneys, Ginkgo and gnetophytes. Gymnosperms and angiosperms together make up sperm or plants with seeds.

    AGE OF THE FISH 21:37

    GREAT EXPLOSION OF LIFE 9:10

    GREAT EXPLOSION OF LIFE 9:10
    The Cambrian explosion or Cambrian evolutionary radiation was the sudden appearance (from a geological point of view) and rapid diversification of complex multicellular macroscopic organisms at the beginning of the Cambrian period, 542/530 million years ago. This period marks an abrupt transition in the fossil record with the appearance of the most primitive members of many phyla of metazoans (multicellular animals).
  • Period: 540 to 245

    PALEOZOIC

    Guide fossil: Trilobites.
    Geological events: Fracturing of Pannota, important mountain emerges in Europe and America and formation of Pangea.
    Climate events: Ordovic glaciation and Carboniferous glaciation.

    PRECAMBIAN

    Guide fossil: Estromatolitos.
    Geological events: The shaping of the Earth´s surface, formation of the supercontinent of Rodinia, formation of Pannotia and formation of the oceans.
