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".
How did the Precambrian Era end?
The Precambrian Era ended around 541 million years ago with the Cambrian Explosion, a period of rapid diversification of life forms. This marked the transition to the Phanerozoic Eon, characterized by the emergence of complex multicellular organisms.
Why did precambrian end?
The Precambrian ended about 541 million years ago.
What marks the end of the Precambrian Eon?
The end of the Precambrian Eon is marked by the beginning of the Phanerozoic Eon, approximately 541 million years ago. This transition is characterized by a significant increase in the diversity of multicellular life forms and the appearance of abundant fossils in the geological record.

The end of the Permian period was also the end of what Era?
The permian period was the end of the paleozoic era.
What was the longest segment of the earth's history?
It was the Precambrian time period.
What was the climate in precambrian time?
In Precambrian times, a relative shortage of volcanoes resulted in low emissions of carbon dioxide. This contributed to low surface temperature, and a lot of glaciers towards the end of the period.
What is the Precambrian Era Known for?
The Precambrian Era is known for being the longest geological time period in Earth's history, lasting over 4 billion years. It is characterized by the formation of the Earth, the evolution of the first life forms, and the development of the atmosphere and oceans. Additionally, the Precambrian is marked by the formation of the first continents and the origins of photosynthesis.
Why did the precambrian end?
The Precambrian ended about 541 million years ago.
Which development marked the end of the prehistorical period and the beginning of the historic period?
The new stone age!
Precambrian are fossils yes or no?
Precambrian is a geologic period that extends as back as 4.500 million years ago. Fossils are very rare from that period of time.
