The methods the geologists used when they first developed the geologic time scale. Were studying rock layers and index fossils worldwide. By Patrick
Paleontologists, stratigraphers, and geochronologists worked with geologists to develop the geologic time scale. Paleontologists studied fossil evidence, stratigraphers looked at the layers of rock formations, and geochronologists used radiometric dating techniques to determine the age of rocks and fossils.
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.

The geologic time scale.
Cenozoic is not a major period of the geologic time scale. The scale is broken down into eras. Cenozoic, Mesozoic and Paleozoic are all part of the Phanerozic era.
Geologic Time. It's called the Geologic Time Scale.

Phanerozoic is the eon which geologic time scale means visable life.
