Geologists have been able to identify crucial episodes in life’s history.

Dividing up deep time The geologic time scale provides the official framework for our understanding of Earth’s 4.5 billion-year history.

Geologists may have voted down formal recognition of the Anthropocene as a geological epoch, but we still need to act to prevent ecological crisis.

The geologic time scale divides Earth’s 4.6 billion-year story into grandly named chapters. Like nesting dolls, the chapters contain sub-chapters, which themselves contain sub-sub-chapters.

Scientists have identified the geological site that they say best reflects a proposed new epoch called the Anthropocene — a major step toward changing the official timeline of Earth’s history.
