the mesoproterozoic was an era itself not a period.
This three eras was included in the Proterozoic Eon.The first Era was the Paleoproterozoic Era;next is the Mesoproterozoic Era;then the last is the Neoproterozoic Era. This another three eras was according to the Phanerozoic Eon.The first Era was the Paleozoic Era;followed up by the Mesozoic Era;then the lastly was the Cenozoic Era.
The Precambrian Era began in the time period 4600 and ended in 570.
The Precambrian is the informal time before the Cambrian Period.It is informally called a Super-Eon and certainly not a geological Era.Geological time intervals from largest to smallest :-Super-Eon - AEonothem (informal)Eon - EonothemEra - ErathemPeriod - SystemEpoch - SeriesAge - StageChron - Chronozone (informal)
The Holocene epoch, The Quaternary period, The Cenozoic era, The Information Decade, The Technology Data, The Caraophone Wire-where era and The Technology Age the next period will begin in 30000 it will be called the Rehostiric Period(meaning dInosaurs or old things may come alive, but humans are or wont be affected)
We just learned about this here in World History, The Elizabethian Era is the answer you're looking for
There is some debate among experts, but it is generally accepted that the Precambrian lasted from 3.9 to 4 billion years. This time period is made up of three eras which are the Paleoproterozoic, the Mesoproterozoic, and the Neoproterozoic era.
The Permian period is the last period of the Paleozoic era
The Hadian Eon (4576.2 to 4000 Million years) has not been subdivided into recognised Era's. The named Era's from oldest to newest are. Eoarchean Era (4,000 to 3,600 Ma) Paleoarchean Era (3,600 to 3,200 Ma) Mesoarchean Era (3,200 to 2,800 Ma) Neoarchean Era (2,800 to 2,500 Ma) Paleoproterozoic Era (2,500 to 1,600 Ma) Mesoproterozoic Era (1,600 to 1,000 Ma) Neoproterozoic Era (1,000 to 542 Ma) Paleozoic Era (542 to 251 Ma) Mesozoic Era (251 to 65.5 Ma) Cenozoic Era (65.5 Ma to Now)
Eon --> Era --> sub-Era --> Period We are currently in: * Phanerozoic Eon * Cenozoic Era * Tertiary sub-Era * Quaternary Period
It really wasn't an era. An Era was a much longer period of time. It was called the "Jurassic Period".
9500 BC.
The Paleocene(65.5 - 55.8Ma) is an epoch in the Paleogene Period(65.5 - 23.3Ma).It is also the 1st Epoch of the Cenozoic Era(65.5Ma - Now).It is also in the Phanerozoic Eon(542Ma - Now).
