Making a Time Line Draw a model of a football field. Starting at the left (4.6 billion years ago) and "moving forward in time," label the 10-yard lines in years. Then, using different colored markers, draw a horizontal line to show the beginning and end of each of the following periods and eras. Cenozoic Era (65 million years ago [mya] to present)

775 Periods may be divided into epochs. Seven epochs are names for the periods of the Cenozoic era. 776 The epochs of other periods usually are just termed early, middle, and late. 777 The Pleistocene epoch, which ended just 10,000 years ago, coincides with a time span commonly known as the ice age.

Geologic Time Scale. Organizing Earth’s History. The . Geologic Time Scale . is a timeline that organizes the events in Earth’s history, like a calendar. Single-celled organisms dominated most of Earth’s history. Plants and fish have only evolved within the past 500 million years. Humans evolved about 110,000 years ago.
