Eons • Largest, most general division of time. • 2 Eons • The eons are: Cryptozoic (Precambrian) eon and Phanerozoic eon.These divisions, in descending length of time, are called eons, eras, periods, epochs, and ages. These units are classified based on Earth’s rock layers, or strata, and the fossils found within them. From examining these fossils, scientists know that certain organisms are characteristic of certain parts of the geologic record.
