Scientists discovered that the eocene time period existed in earth’s history around 34 mya.

what do they need to do to determine what time period eocene belongs to on the geologic time scale?

learn what happened during precambrian time
study information related to the cenozoic era
view the timing of events in the mesozoic era
research events that happened during the paleozoic era

study information related to the Cenozoic era

Explanation:

A good understanding of the geologic time scale is required here.

The absolute age of 34mya for the Eocene falls in the Cenozoic era.

The geologic time scale is divide into Eons, Eras, Periods, Epoch, Age.

The Eons are larger divisions than any other group.

The GTS is divided into 4 era:

Precambrian

Paleozoic

Mesozoic

Cenozoic

The Precambrian era is the oldest while the Cenozoic is just a few million years.

The age of the Cenozoic lies between Recent to 66mya ago. This is where the Eocene should lie.

d. they are naturallyoccuring inorganic fuels like coal and petroleum.
