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 is the oldest geologic period?
The earliest geological period is known as the Precambrian. This is a very long period of time which begins about four and a half billion years ago, with the formation of the Earth, ending at the beginning of the Cambrian Era which is about 541 million years ago. So the Precambrian is about four billion years long, longer than all other eras combined.
Which Era is the longest Precambrian Paleozic Mesozoic or Cenozoic?
Precambrian
How long hadean era last?
The Hadean Eon lasted from Earths formation about 4.5762 billion years ago until 4 billion years ago, some 576.2 million years.
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.
What is the time range of Precambrian Era?
Precambrian time - The period in the geologic time scale from the formation of the Earth to the beginning of the Palezonoic era, from about 4.6 billion to 543 million years ago.
What geologic era lasted longest?

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.
Is the Mesozoic Era the longest?
The answer is NOOOO!!!! It is not the longest Era!!! The Precambrian consisted of the Archean and Proterozoic Eras which each pull roughly 2 billion years of geologic time making up the first 4 billion years of Earth. The Archean from 4.5 Billion Years Ago to about 2.5 BYA and the Proterozoic from 2.5 BYA to about 570 MYA. The Paleozoic which preceded the Mesozoic lasted about 345 Million years (570 MYA- 225 MYA) and the Mesozoic lasted about 215 Million years (225 MYA- 65 MYA).

What era was 3.5 billion years ago?
3.5 billion years ago was the Paleoarchean Era(3,600 - 3,200Ma). This was in the Archean Eon(3,800 - 2,500Ma) & during the Precambrian SuperEon(4,500 - 542Ma).
