What happens during the Precambrian era?
This era began with the formation of the earth from dust and gas orbiting the Sun about 4.6 billion years ago. During this era the surface of the Earth was like popular visions about Hades: oceans of liquid rock, boiling sulfur, and impact craters everywhere!
What major events happened during the Precambrian time?
This division of time — about seven-eighths of Earth’s history — lasted from the first formation of the planet (about 4.6 billion years ago) to the geologically sudden diversification of multicellular life known as the Cambrian Explosion (usually dated at about 542 million years ago).
What life forms were in the Precambrian era?
The only multi-cellular life forms at the end of the Precambrian were in the oceans and included some groups that have survived until the present: jellyfishes and segmented worms (annelids). There was nothing yet on land except the wind.
When did the Precambrian occur?
4,600 million years ago – 541 (+/- 1) million years ago

How long is the Precambrian era?
about 4.6 billion years ago
Precambrian, period of time extending from about 4.6 billion years ago (the point at which Earth began to form) to the beginning of the Cambrian Period, 541 million years ago.
How did the Precambrian period ended?
541 (+/- 1) million years ago

What time era do we live in?
Holocene
According to the International Union of Geological Sciences (IUGS), the professional organization in charge of defining Earth’s time scale, we are officially in the Holocene (“entirely recent”) epoch, which began 11,700 years ago after the last major ice age.
What period are we living in now?
Currently, we’re in the Phanerozoic eon, Cenozoic era, Quaternary period, Holocene epoch and (as mentioned) the Meghalayan age.
Which era is the oldest?
Paleozoic Era
The oldest is the Paleozoic Era, which means “ancient life.” Fossils from the Paleozoic Era include animals and plants that are entirely extinct (e.g., trilobites) or are rare (e.g., brachiopods) in the modern world.
What era are we in technology?
Information Age
The Information Age (also known as the Computer Age, Digital Age, or New Media Age) is a historical period that began in the mid-20th century, characterized by a rapid epochal shift from the traditional industry established by the Industrial Revolution to an economy primarily based upon information technology.
