Which of the four major division of the GTS occupied the largest unit of time in Earth history?
eons
The largest units of time are eons; the 4.6 billion years of earth’s history are divided into four eons. The Phanerozoic Eon includes the most recent 545 million years and the most detailed fossil record.
Which chunk of time is bigger?
Eons
Scientists have divided this timeline into huge “chunks”, or intervals, of time. The largest “chunk” of time is known as the Supereon. Supereons are broken down into smaller units of time called Eons. Eons are further divided into Eras, and Eras are divided into periods.
What is the longest time frame?
In formal usage, eons are the longest portions of geologic time (eras are the second-longest). Three eons are recognized: the Phanerozoic Eon (dating from the present back to the beginning of the Cambrian Period), the Proterozoic Eon, and the Archean Eon. Less formally, eon often refers to a span of one billion years.
What is the longest epoch?

How long ago did the present eon begin?
about 2.5 billion years ago
Phanerozoic Eon, the span of geologic time extending about 541 million years from the end of the Proterozoic Eon (which began about 2.5 billion years ago) to the present.
