Sloan [31]

Answer:

To understand what era the Eocene period belongs to on the geologic time scale, the scientist would have to examine the Cenozoic era to understand all information related to it.

Explanation:

First, let's start with an explanation of terms.

  • MYA simply means Millions of Years Ago
  • Time Scale is a sequence or organisation of events which is used as a yardstick to measure the duration of history or how long the earth has existed.
  • Eocene Period refers to the geological epoch that lasted from about fifty-six to approximately forty MYA. It is also defined as the second epoch of the Paleogene Period within the modern Cenozoic Era.  

Given the definition of the Eocene Period, to understand what era an Eocene period belongs to, the person must carefully study the Cenozoic era.

Cheers!
