Time Span: 65 million to 2.6 million years ago.

The Tertiary Period is made up of 5 epochs:
  • The Paleocene Epoch - 65 to 54 million years ago
    • Earth's pole were temperate, as well as most continents.
  • The Eocene Epoch - 54 to 38 million years ago
    • The planet's temperature begin to rise.
  • The Oligocene Epoch - 38 to 24 million years ago
    • Ice covers South Pole but not North Pole, generally warm temperatures.
    • Open grasslands and deserts are common.
    • Mamals grow in size, includes:
      • horses, entelodonts, rhinoceroses, oreodonts, and camels
  • The Miocene Epoch - 24 to 5 million years ago
    • Cooler and drier climates lead to weakened forests.
    • Africa pushes into Europe creating alps.
    • Arctic becomes covered in ice.
    • Animals include:
      • Mammals and birds were well-established. Whales, seals, and kelp spread.
      • Large mammals i.e. horses, camels and rhinos.
      • Smaller mammals such as beavers.
      • Diverse amounts of apes and primates appear.
  • The Pliocene Epoch- 5 to 1.8 million years ago
    • Climate is similar to today's.
    • Continental movement leaves Earth looking much like it does today.
    • First hominids appear, ancestors of current humans.
    • During the Pliocene epoch climate became cooler and drier, and seasonal, similar to modern climate.

  • The Tertiary Period was apart of the Cenozoic Era.
  • Began with the Cretaceous–Tertiary extinction event.
