The current eon is the Phanerozoic Eon, which began approximately 541 million years ago and continues to the present day.
Step 3:: Identify the Era
Within the Phanerozoic Eon, we are currently in the Cenozoic Era, which began about 66 million years ago after the extinction of the dinosaurs.
Step 4:: Identify the Period
In the Cenozoic Era, we are currently in the Quaternary Period, which began approximately 2.58 million years ago.
Step 5:: Identify the Epoch
The current epoch is the Holocene Epoch, which started about 11,700 years ago at the end of the last Ice Age.
Final Answer
- Eon: Phanerozoic - Era: Cenozoic - Period: Quaternary - Epoch: Holocene Note: Some geologists are now discussing the potential designation of a new epoch called the Anthropocene, reflecting human impact on the Earth's geology and ecosystems, but this is not yet officially recognized by the International Commission on Stratigraphy.
