The Longest Era of Earths History is Paleoproterozoic Eralasting 900 million years.
The largest unit of time in relation to Earth's history is the super-eon. Super-eons are divided into eons. Eons in turn are divided into eras, eras are divided into periods, periods into Epochs and Epochs in Ages.
Precambrian Super-Eon (4,600 - 542 Ma)
Hadean Eon (4,600 - 3,800 Ma)
Archean Eon (3,800 - 2,500 Ma)
- Eoarchean Era (3,800 - 3,600 Ma)
- Paleoarchean Era (3,600 - 3,200 Ma)
- Mesoarchean Era (3,200 - 2,800 Ma)
- Neoarchean Era (2,800 - 2,500 Ma)
Proterozoic Eon (2,500 - 542 Ma)
- Paleoproterozoic Era (2,500 - 1,600 Ma)
- Mesoproterozoic Era (1,600 - 1,000 Ma)
- Neoproterozoic Era (1,000 - 542 Ma)
Modern Super-Eon (542 Ma - Now)
Phanerozoic Eon (542 Ma - now)
- Paleozoic Era (542 -251 Ma)
- Mezozoic Era (251 - 65 Ma)
- Cenozoic Era (65 Ma - Now)

Where was precambrian era?
it was on earth the precambrian era is an era that happend several million years ago on the earths surface
What is the Archean era?
The Archean era is the earliest Precambrian era, archean means "ancient" or "beginning". The Archean era starts with the oldest known rocks, about 4.6 billion years ago.
The longest era lasting about 4 billion years was what era?
The Precambrian Super-Eon is the informal name for the time on earth before the Cambrian Period. It lasted from 4,576 millions years ago until 542 million years ago, about 4.034 billion years.No geological era lasted as long. The longest era was the Paleoproterozic Era(2,500 - 1,600Ma) which lasted 900 million years.
Which Era is the longest Precambrian Paleozic Mesozoic or Cenozoic?
Precambrian
What is The Oldest Period in the Mesozoic Era?
Statistical analysis of the fossil records indicates that somewhere around 35% of all species disappeared at the end of the Cretaceous Era (there is considerable margin for error in that figure).
What are the 4 eras in earths history?
precambrian era, paleozoic era, mesozoics era, cenozoic era
What was earths atmosphere oceans and continents began to form during a period of earths history called?
precambrian era
What percenatge does the precambrian era take up in the earths history?
The precambrian era lasted from roughly 4.57 Ga to 0.54 Ga before today, equalling about 88 % of Earth's history.
Is The Paleozoic Era the longest time period in the history of Earth.?
The Precambrian is actually the longest block (division) of time in earth geological history. But the Paleozoic era is the longest of the three "eras". The paleozoic era started about 550 million years ago and is marked by the appearance of abundant invertebrate life in the oceans. The paleozoic era ended about 225 million years ago with the forming of the supercontinent Pangaea.
What was the longest lasting government?
The Althingi was established in 930 in Iceland by Viking-era settlers. The world's oldest legislative body is now Iceland's official parliament.
Which eon did most of earths history occur in?
Most of Earth's history has occurred in the Precambrian Era, a time span of over 4 billion years.
According to its name the archaeozoic era of earths history was characterized by what type of life form?
unicellular organisms are earliest forms of life

What are the prehistoric eras?
There are so far 4 Eras in the earths history. the one that started the beginning if the earths history: Precambrian Time. The one after that was the Paleozoic Era, which means "ancient life." next was mesozoic which means "middle life" the one we are in is called the Cenozoic Era which means" recent life." * All Eras ended with a mass extinction.
The oldest era?
Its Archeozoic.
What was the longest era?
Precambrian
Which era spans the greatest number of years in earths geological history?
The pre-Cambrian period which is a little over 630 million years ago. Before this era, there were no biota which leave a decent fossil impression - mainly soft-bodied forms. But see Ediacara in Wikipedia for more information.The earth by comparison is about 4.5 billion years since formation in roughly its present form. [So 630/4.5 000 ]
