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 - Eonothem
- Era - Erathem
- Period - System
- Epoch - Series
- Age - Stage
- Chron - Chronozone (informal)

What event marked the end of the Precambrian Era?
The Precambrian Era ended with the beginning of the Cambrian Period, approximately 541 million years ago. This period is characterized by the sudden appearance of a diverse range of complex life forms in the fossil record, known as the "Cambrian explosion".
What era featured the longest periods with no life forms on Earth.?
Precambrian
What era is furthest in the past?
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 ]
What are the four geologic time scale eras from oldest to most recent?
The 4 eras are Cenozoic era, the mesozoic era, the paleozoic era, and the precambrian era.
When did the precambrian era begin?
The Precambrian Era began in the time period 4600 and ended in 570.
What was the Precambrian era's climate?
The Precambrian is a long period and just as Earth has many climates now, it had many then.
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.
Which describes the correct order of the geologic time scale from oldest to most recent?
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 ;)
What is the oldest era geologically?
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.
Which period of Earth's time would be considered the longest?
The period of Earth's time that would be considered longest is the Precambrian Era.
Which Era is the longest Precambrian Paleozic Mesozoic or Cenozoic?
Precambrian
How are animals from the Precambrian era generally characterized?
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.
What is the longest era with the least information available?
The Precambrian era is the longest geological era, spanning from about 4.6 billion years ago to 541 million years ago, but it is also the era with the least amount of detailed information available due to the lack of well-preserved rocks and fossils from that time period.
What event marked the end of the Precambrian Era?
The Precambrian Era ended with the beginning of the Cambrian Period, approximately 541 million years ago. This period is characterized by the sudden appearance of a diverse range of complex life forms in the fossil record, known as the "Cambrian explosion".
Did the precambrian era occur first?
Yes, the Precambrian era is the earliest part of Earth's history, spanning from about 4.6 billion years ago to 541 million years ago. It is followed by the Paleozoic era.
Historians know least about era do?
**Precambrian**
