Geological epochs in order

This is wrong, in Geochronology paleocene, eocene,oligocene myocene ,pliocene are NOT periods but Epochs. The period list also should have included Paleogene and Neogene (old Tertiary period) and Quarternary period. The epoch table should have included the Holocene Epoch, which followed the Pleisticene. Sequence is Eons-eras-periods epochs-ages

Faunal succession: is the time arrangement of fossils in the geological record. Formations: are stratigraphic successions containing rocks of related geological age that formed within the same geological setting. Ga: is an abbreviation used for billions (thousand million) of years ago. Geochronology: is the study of the age of geological materials.The geological Periods can be further subdivided, into Epochs and Ages. At the finest levels, most day-to-day practical time-slicing (or geological correlation, to be more correct) is still done using fossils. Some fossils aren’t very good for this - dinosaurs, for instance, which are large and rare and geographically restricted. The geologic time scale is the “calendar” for events in Earth history. It subdivides all time into named units of abstract time called—in descending order of duration—eons, eras, periods, epochs, and ages.Long before geologists had the means to recognize and express time in numbers of years before the present, they developed the geologic time scale.This time scale was developed gradually, mostly in Europe, over the eighteenth and nineteenth centuries.
