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.

What are the phanerozoic periods in order?
The Phanerozoic Eon is divided into three major eras: the Paleozoic Era, the Mesozoic Era, and the Cenozoic Era. The Paleozoic Era is further divided into six periods: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The Mesozoic Era is divided into three periods: Triassic, Jurassic, and Cretaceous. The Cenozoic Era is divided into two periods: Paleogene and Neogene.
Which era is divided into both periods and epochs?
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.
Carboniferous period was subdivided into what two periods?
The Carboniferous period is subdivided into the Mississippian and the Pennsylvanian periods.
What is the periods of Cenozoic era are subdivide into?
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.
Eras are divided into periods which can be further divided into?
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 Mesozoic Era is divided into three periods: Triassic, Jurassic, and Cretaceous. The Cenozoic Era is divided into two periods: Paleogene and Neogene.
How many periods are in each era?
there are different periods in each era. In the Cenozoic era, there are 2 periods, Quaternary and Tertiary. Mesozoic era has 3 periods, Cretaceous, Jurassic, and Triassic. Paleozoic has 7 periods, Permian, Carboniferous, Devonian, Silurian, Ordovician, and Cambrian. Precambrian is just the present, no time periods in it.
Which era is divided into both periods and epochs?
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.
What are the periods of the Cenozoic era?
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.
Which eras on the geologic time scale is divided into both periods and epochs?
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.
What are the periods of the Cenozoic?
The Cenozoic era has three periods. These periods include the Paleogene, the Neogene, and Quaternary. This era covers a span of 66 million years ago until present time.
Which of these was NOT a period of the Cenozoic Era Tertiary Quaternary Cretaceous all of these are periods of the Cenozoic Era?
The question is very muddled but it can be answeredThe Cenozoic Era started with the end of the dinosaurs and is ongoing 65.5 mya to the present thereforeOf the above the following are in the Cenozoic:QuaternaryTertiaryAnd the following are out of (older than) the Cenozoic:Cretaceous
What years did the Cenozoic period exist?
The last 65 million years. It is the current era and is divided into three periods; the Paleogene, Neogene and Quaternary.
What is Earths most recent era?
We are currently in the Cenozoioc Era (sub-era Tertiary); the era is divided into 3 periods, starting with the Palaeogene, then the Neogene, & now the Quaternary period. The era before this one was called the Mesozoic Era
Why is the shortest era on the timeline the Cenozoic era divided into so many smaller divisions?
You can't say it's the shortest, its length is unknown as of now because the Cenozoic era isn't over yet. But it is divided into smaller sections because the most geological and biological changes have happened during the Cenozoic Era, so they break it up, get it?
Carboniferous period was subdivided into what two periods?
The Carboniferous period is subdivided into the Mississippian and the Pennsylvanian periods.
What is the periods of Cenozoic era are subdivide into?
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.
