The Phanerozoic era.
After an era, the next smallest division of time would be an epoch. An epoch is equal to around 10,000,000 years, where as an era is 100,000,000 years.
A period is smaller than an era in the geologic time scale. It is further subdivided into epochs and ages.
The 3 eras of geologic time is Palezozoic era, Mesozoic era, and Cecozoic era
Penguins first appeared during the Paleocene epoch, which is part of the Cenozoic era in the geologic time scale. This period lasted from about 66 to 56 million years ago.
The order of units of geologic time from longest to shortest is: eon, era, period, epoch.
an era is a very long span of geologic time
The earliest era is the Cryptic era (an informal designation) for the earliest part of the Hadean eon which is not technically seperated into era. The first formal era is the Eoarchaean.
No, a geologic era is a longer unit of time than a geologic period. Geologic eras are divided into periods, which are further subdivided into epochs. The hierarchy from largest to smallest is era, period, epoch.
In geologic time, the Hadean is the first EONof Earth's history, from it's formation 4.57 billion years ago to about 4 billion years ago. The Hadean is not an era, which is a smaller subdivision of geologic time.
Era
After an era, the next smallest division of time would be an epoch. An epoch is equal to around 10,000,000 years, where as an era is 100,000,000 years.
