The period is the basic unit of geological time in which a single type of rock system is formed. Two or more periods comprise a geological Era. Two or more Eras form an Eon, the largest division of geologic time. Some periods are divided into epochs. The major periods in the geologic history of the Earth are (mya=million years ago): EON.
What is eon era period and age epoch? Epochs are the smallest divisions. Many epochs make up a period, many periods make up an era, and many eras make up an eon. In defining the boundaries between major divisions, we often use markers, like the dinosaur extinction or the appearance of certain organisms. The Paleogene Period (or the early part of the Tertiary Period) represents the time period after the major extinction that wiped out the dinosaurs and about half of the known species worldwide.

Reptiles were common and the first dinosaurs evolved. Permian During the Permian Period, Britain lay on the supercontinent of Pangaea and experienced hot, dry conditions.
The geologic time scale is a system used by scientists to describe Earth's history in terms of major geological or paleontological events (such as the formation of a new rock layer or the appearance or demise of certain lifeforms).
