The geological era that is divided into both periods and epochs is the Cenozoic Era. The Cenozoic, which began about 66 million years ago and continues to the present, is subdivided into three periods: the Paleogene, Neogene, and Quaternary. Each of these periods is further divided into epochs that reflect significant changes in Earth's climate, geography, and life forms.

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 age of the Earth is measured in geologic time scales that are divided into eras, which are then further divided into periods, epochs, and ages. The current era we are in is the Cenozoic era, and within this era, we are in the Holocene epoch. These divisions help scientists study the Earth's history and understand how life has evolved over time.
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.
The third largest division of geologic time is an era. The eras are further divided into periods, epochs, and ages.
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.

US history is typically divided into the following epochs: Pre-Columbian era, Colonial era, Revolutionary era, Early Republic era, Civil War era, Reconstruction era, Gilded Age, Progressive era, World War era, Cold War era, Civil Rights era, and Modern era. Each of these epochs represents significant periods of change and development in American history.
The major divisions of Earth's history are typically divided into eons, eras, periods, and epochs. The current eon is the Phanerozoic, which is divided into eras such as Paleozoic, Mesozoic, and Cenozoic. Each era is further divided into periods, like the Jurassic period within the Mesozoic era. Periods can be subdivided into epochs, such as the Pleistocene epoch within the Quaternary period.
The age of the Earth is measured in geologic time scales that are divided into eras, which are then further divided into periods, epochs, and ages. The current era we are in is the Cenozoic era, and within this era, we are in the Holocene epoch. These divisions help scientists study the Earth's history and understand how life has evolved over time.
The next term in the sequence "Era, Period" is "Epoch." This sequence reflects the hierarchical classification of geological time, where an era is subdivided into periods, and periods can further be divided into epochs. Thus, after "Period," the logical progression leads to "Epoch."
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.
The third largest division of geologic time is an era. The eras are further divided into periods, epochs, and ages.
The time periods of the Paleozoic and Mesozoic are subdivided into early middle and late instead of named epochs as they are in Cenozoic periods is due to the basis of the occurrence of particular fossils. It is also based upon the absence or appearance of geological horizons.
The Geological eras can be divided into three major eras: Paleozoic, Mesozoic, and Cenozoic. These eras represent different periods in the Earth's history marked by significant geological and biological changes. Each era is further subdivided into periods, epochs, and ages.
