    Tertiary Period

    This Era started 65 million years ago and finished 2 million years ago.
    This Era is split into 5 parts.This was the Era of mammals.
    Life in the Tertiary Era On land, the age of the mammals was beginning. Rodents evolved, as well as gliding mammals and the early primates. Sharks and fish took over from marine reptiles. Towards the middle of this Era, the ancestors of elephants, horses, cattle, pigs, rhinos and deer appeared. Other mammals such as whales and sea cows took to the water.
  • Period: to

    Paleocene Epoch

    The Rise of The Mammals
    The extinction event at the close of the Cretaceous Period wiped out the dinosaurs, large reptiles, and many other species. This left room for new animals to develop. The mammals became the dominant animals. In fact, the Cenozoic Era is often called the Age of Mammals.

    aquatic mammals
    mammals that live in the water began evolving at this time for example: whales

    most of the archaic mammals disappeared to be replaced by modern mammals.
  • Proconsul

    Proconsul
    Proconsul is the best known primate hominoid from about 25 million years ago (the early Miocene) in Africa
    Proconsul still had many ape-like features, e.g., in the ankles, feet, and teeth, but had an opposable thumb, shoulder, and comparatively large brain like later hominids
  • Megalodon

    Megalodon
    the
    largest shark known in the history of the Earth, Megalodon,
    existed from about 16 to 1.6 mya. This marine monster was at

    weighed as much as 20 times more.

    During the Pliocene the first hominids appeared; these were our human ancestors!

    Position of Continents
    Approximately 2.6 million years ago the continents assumed their present-day positions. As a result of tectonic activity between Europe and North America land bridges were broken.

  • ice age begins

    ice age begins
    The cooling climate of the Tertiary Period led to huge glaciers at the poles. The mountains of the world were also covered by glaciers, including the newly formed Himalayas and Alps. The huge amounts of water locked up in the ice lowered the level of the sea and land bridges appeared:
