Periods are subdivided into periods of time know as epochs.
The Cenozoic era is subdivided into two periods: the Paleogene and the Neogene. The Paleogene includes the Paleocene, Eocene, and Oligocene epochs, while the Neogene includes the Miocene and Pliocene epochs.
Geological eras can be divided into periods, epochs and ages.
Eons, eras, periods, and epochs are hierarchical divisions of geological time used to organize Earth's history. Eons are the largest time frames, subdivided into eras, which are further divided into periods, and then into epochs. This system allows scientists to categorize significant events in Earth's history, such as major geological and biological changes. Each division reflects varying lengths of time, with eons encompassing billions of years and epochs spanning millions of years.
The geological time scale is divided into eons, eras, periods, and epochs. Each represents a different span of time in Earth's history, with eons being the largest divisions and epochs being the smallest. This hierarchical structure helps organize Earth's history into manageable units for study and understanding.
Eras divide into periods and periods divide into epochs. The Palaeozoic Era is composed of the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian periods (in that order). The Mesozoic Era is divided into the Triassic, Jurassic and Cretaceous periods. The Cenozoic Era is divided into the Tertiary and Quaternary periods. The Tertiary period is divided into the Palaeocene, Eocene, Oligocene, Miocene and Pliocene epochs while the Quaternary period is divided into the Pleistocene and Holocene epochs. Note that eras are not the longest lengths of time. Eras may compose longer stretches of time known as eons/aeons.
The Cenozoic era on the geologic time scale is divided into periods and epochs. This era includes periods such as the Paleogene and Neogene, which are further divided into epochs like the Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, and Holocene.

The geological time scale is the history of the earth. This is in the eras period and epochs.
The Cenozoic era is subdivided into two periods: the Paleogene and the Neogene. The Paleogene includes the Paleocene, Eocene, and Oligocene epochs, while the Neogene includes the Miocene and Pliocene epochs.

Geological eras can be divided into periods, epochs and ages.
An eon is longer than an epoch. Eons are the largest divisions of geological time, typically spanning hundreds of millions to billions of years, while epochs are subdivisions of periods, which are themselves part of eons. For example, the current eon, the Phanerozoic, contains several periods, each of which can be further divided into epochs.
The Cenozoic Era is divided into three periods: the Paleogene, the Neogene, and the Quaternary. The Paleogene includes the Paleocene, Eocene, and Oligocene epochs. The Neogene includes the Miocene and Pliocene epochs. The Quaternary includes the Pleistocene and Holocene epochs.

Geologic time consists of eons, eras, periods, epochs, and ages. These measure periods of billions or millions of years.
