• • Ice age advances occur during Pleistocene
  • Many organisms go extinct with ice age climate changes
• 1. Tertiary Period

  • Marks the beginning of the Cenozoic Era
  • The Paleocene Epoch 65 to 54 million years ago
  • The Eocene Epoch 54 to 38 million years ago
  • The Oligocene Epoch 38 to 24 smillion years ago
  • The Miocene Epoch 24 to 5 million years ago
  • The Pliocene Epoch 5 to 1.8 million years ago
• 1. Quaternary Period

  • The Quaternary Period began with an ice age about 1.8 million years ago. 
  • It is often called the Age of Humans
  • The Pleistocene Epoch (Ice Age) 1.8 million to 11,000 years ago
  • The Holocene Epoch - 11,000 years ago to present
• pliocene appearance of first hominids
