The Phanerozoic Eon began around 540 million years ago. This eon is marked by the appearance of abundant and diverse forms of life, including the emergence of complex multicellular organisms. It is divided into three major eras: the Paleozoic, Mesozoic, and Cenozoic, each characterized by significant evolutionary events and mass extinctions. The Phanerozoic continues to the present day.

When did the tertiary period start and end?
The Tertiary Period began roughly 65 million years ago following the mass extinction event that ended the Cretaceous Period. It ended about 2.6 million years ago, marking the beginning of the Quaternary Period.
What is the length in millions of years of the Tertiary period?
The answer is 63.2 million years. Since the Tertiary Period began 65 million years ago and then stoped 1.8 million years ago you have to subtract the 1.8 million from 65 million to get the actual lenght of time.
