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 :-
The named periods of the Precambrian SuperEon(4576.2 - 542Ma) are:-
Hadean Eon (4,576.2 - 4000 Ma)Archean Eon (4,000 - 2,500 Ma)Eoarchean Era (4,000 - 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 - 1,600Ma)
Mesoproterozoic Era (1,600 - 1,000Ma)
Neoproterozoic Era (1,000 - 542Ma)
archaeozoic era
570-240 mya
The Precambrian period was followed by the Cambrian period, the first period of the Paleozoic era.
Cambrian Period
Precambrian is BEFORE the Cambrian period!
The Archean Eon, which is part of the Precambrian period along with the Proterozoic Eon.
The 4 eras are Cenozoic era, the mesozoic era, the paleozoic era, and the precambrian era.

Precambrian !!!
The Precambrian Era began in the time period 4600 and ended in 570.
The Precambrian is a long period and just as Earth has many climates now, it had many then.
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.
The oldest geological era is the Precambrian period. It is the period of Earth's formation, as well as the origin of the first single and multi-celled organisms.
ok im going to start off by saying this, the last answerer is stupid, and doesnt know what he is talking about. it goes from: PERIOD ERA EPOCH there you go ;)
The period of Earth's time that would be considered longest is the Precambrian Era.
Precambrian
The animals in the Precambrian Period were soft bodied animals. This Era was dominated by single celled organisms: algae, bacteria. Also in existence were jellyfish, spiders, crabs, and worms.
Yes. The first era was the precambrian era followed by the paleozoic era then the mesozoic era than the Cenozoic era.
